Well-Adjusted Barely Traumatized Demon Slayer (Murata SI-ish)

[DeeplyoftheWorld]

A/N: As several characters have aged/don't exist in the original Kimetsu Academy but do in this fic, some positions and roles have been adjusted.

Kibutsuji Muzan, a diet member of Japan's parliament, was an ambitious man and would not hesitate to be ruthless. 'Lawfully' and within reason, of course.

Amateurs broke laws. Professionals bent, twisted, chewed up, and spat out the remnants of legislation.

Staring at his new recruit, he allowed himself to smile. The young man quickly graduated from a good university in Tokyo, and he had a close ear to Ubuyashiki Kagaya.

Sato Murata wanted to be a politician in the future. In terms of starting his career and learning under someone, who was better than Muzan?

In Muzan's mind, it was a trick question, because there was no one more suited than him. Of course he was an obvious choice. However, Murata's connection with Kagaya could be as much a blessing and a curse, so it was best to start small.

"I'll have you acquainted with the others, but for now, I'll have you do odd things here and there. Since you recently graduated, you can go rest in your hometown. Maybe even visit that academy you were once a student in," Muzan ordered.

There was no 'maybe.' Visit the academy, update any intelligence or people of note, and return to report his findings.

At least, that was how Murata viewed it. Muzan didn't do nice for the sake of it. If he offered a suggestion, then it was best to follow through with it.

"Understood, sir. I'll be off, by your leave?" Murata asked.

Crawling in paperwork, Muzan waved him off.

-

Sato Murata, twenty-three years old. He graduated university a year early, and because of his grandfather's influence, desired to work in the government as a parliament member.

Old man Sato was a former governor of a large city, but retired to be a convenience store owner. The change of pace visibly slowed down the graying of his hair, which Murata found telling of the stress with politics.

Sato was a good friend of the previous Ubuyashiki head, and by association, Murata held a good relationship with the current head, Kagaya Ubuyashiki.

They met in Kagaya's mansion, drinking tea and sharing a small meal.

"How was the first meeting? Was it as dreadful as you imagined?" Kagaya teased, enjoying the tired look on Murata's face.

Murata sighed, running a hand through his hair. "I'm more worried about the rumors of his secretary. But, his actual name is Michikatsu, not Kokushibo."

Kagaya smiled. "I figured as such. So, Muzan wants you to visit the school?"

"Yes. He's been complaining about Nakime's rivalry with your wife, and how she's been hitting a roadblock with her influence," Murata explained.

Kagaya laughed and finished his tea. "Well, you can go to the academy whenever you wish. Having a graduate come by is always exciting for the younger students."

"Of course. Also, is Sanemi actually a teacher now?"

Murata didn't believe the news at first. Even more so when the subject involved mathematics.

Sanemi was ruthless with numbers, surprisingly gifted at the subject.

Notoriously, Sanemi proved to be a scary and even more ruthless tutor. Murata had many unforgettable memories of Sanemi when they were students themselves.

"He may seem scary, but he is efficient and dedicated. Makomo is the Japanese teacher as well."

"Oh. That's good to hear."

Another set of memories resurfaced. The good, the bad, and the very good.

"Well, don't forget to rest before you come by. I know you have your own ambitions, but I also want to thank you for fulfilling an old friend's needs."

Murata laughed, giving Kagaya a small hug. "Anything for you, got that? If it helps you and helps me, then I would even work for a demon."

-

Staring at the gates of the academy, Murata exhaled a breath of nostalgia.

Kimetsu Academy was a private organization that held elementary, junior high, and high school levels of education. The school produced several influential graduates, and was only one of several enterprises the Ubuyashiki family owned.

They maintained a wide network in several fields, mostly to slow down Muzan's own goals.

Despite being a private school, it was cheap compared to other schools of its nature. Walking towards the gate, he saw a boy standing guard.

"Hold on, hold on! That's not the official school uniform," Zenitsu said, bringing up his clipboard.

Murata's eye twitched. He was just below the average height for a Japanese man. With his youthful face, even store clerks were hesitant to sell him alcohol.

He brought out his identification. "I'm not a student, just a graduate visiting his old school."

Zentisu apologized and bowed. Murata went on his way.

Unbeknownst to Murata, Zenitsu crushed the pencil on his right hand while the other sent cracks through the clipboard.

Seeing the name on Murata's identification brought back an embarrassing memory.

-

When Gyomei became the homeroom teacher for a different class, Zenitsu was excited.

Rumors spread that the new Japanese instructor was going to be their homeroom teacher.

A woman walked in, her black hair and light blue eyes captivating Zenitsu.

So beautiful!

"Ishikawa Makomo," she introduced herself, writing the name on the chalkboard. "As your homeroom and Japanese teacher, I hope to prepare all of you to the best of my ability. Any questions?"

Hands rose up as students murmured amongst one another. Zenitsu was lost in his own world.

A few weeks later, he professed his admiration of Makomo to the woman herself.

To anyone from the outside looking in, Zenitsu committed to what looked like a love confession. Admiration, for him, went beyond a simple compliment. His heavy handed approach often backfired on him.

Unfortunately for Zenitsu, Sanemi was walking through the hallway within earshot. He immediately gave Zenitsu detention for unprofessional conduct and dragged Makomo away, grumbling along the way.

"If I were Murata, I'd rip the kid's head off."

Makomo smiled, chuckling to herself. "It was just a harmless compliment. Living out their youth is what students should do."

Zenitsu heard all of it with his enhanced hearing. He vowed to never forgive the man who already took away any chance he had.

-

When he took off his shoes and entered the school, Murata saw the principal waiting for him.

"You didn't have to go out of your way to do this," he said.

Amane shook her head. "I have time. What better way to spend it than with a graduate and old friend?"

He had no objections, so they slowly explored the school. While the building itself hasn't changed much in the time he's been gone, there were many more faces than his time. Some familiar people, but most were new.

A dull pain erupted in Murata's back and the offending student apologized for bumping into him.

Murata's eyes widened in recognition. "Tanjiro?"

Rubbing his head, Tanjiro smiled when he opened his eyes. "Ah, Mr. Sato! It's good to see you! Are you going to be a teacher here?"

Tanjiro had fond experiences of the budding politician, remembering the late nights of tutoring.

Murata shook his head. "No, I'm just here to relive some nostalgia. The principal is showing me around."

The school bell rang, causing Tanjiro to freeze in fear. "I'm late for Mr. Shinazugawa's class!"

Murata plopped a hand on Tanjiro's shoulder, preventing him from running.

"I'll walk there with you. You're in luck, since Sanemi won't try to kill me."

Tanjiro cried, his face glowing in appreciation. "Thank you, thank you so much!"

Amane left the two of them, but not before wringing a promise from Murata to visit later. Tanjiro took charge and walked quickly, hurrying despite Murata's lack of concern.

Opening the door, Tanjiro was met with Sanemi's yelling. His voice rumbled like a typhoon.

"Kamado Tanjiro! Detention for being late!"

Murata popped behind him, explaining Tanjiro's tardiness. Sanemi grinded his teeth while coming up with a rebuttal, but ultimately let it go.

"Fine. Next time it happens, I won't tolerate it. Understand?"

Tanjiro fearfully nodded and swiftly took his seat.

"As for you," Sanemi pointed at Murata, "go hang out in the teacher's lounge or something. Get the hell out of my sight."

Mocking a salute, Murata exited and made his way to the lounge, happy to see that Sanemi hadn't changed a bit.

-

Ubuyashiki Kagaya: The head of the Ubuyashiki family. Besides owning Kimetsu Academy, Kagaya maintains holdings in the agricultural, technological, and political landscape. His wide network allows him to help counter Muzan's efforts. Some say he has a third eye for investments.

Ubuyashiki Amane: Wife of Kagaya. She is the principal of Kimetsu Academy. Her calm and serene appearance intimidates some students, but most see her as a respectable and kind woman. Has a strange rivalry with her vice-principal.

Kibutsuji Muzan: A charismatic and devious man who is a diet member of the Japanese parliament. Wants to take over Japan one day. Has a large following, yet many people also dislike him. Children think he looks scary.

Inoue Nakime: Vice-principal of Kimetsu Academy. She is one of Muzan's trusted associates and spies. Performs biwa concerts on her off days, which help raise quite a bit of money. Dislikes Amane.

Kokushibo (real name Michikatsu): Muzan's secretary. Often mistaken for a bodyguard because of his strength. There are rumors that he was once a member of American Special Forces, that he killed a man with a toothpick, and that he robbed the second-largest bank in Russia by impersonating an oligarch.

Sato Murata: A budding young man who wants to be a politician. Childhood friends with Makomo. Good friend of Kagaya since Kagaya's father and Murata's grandfather were friends.

Old man Sato: Murata's nickname for his adoptive grandfather. Technically, they are related, but only on his mother's cousin's side.

Shinazugawa Sanemi: Kimetsu Academy's mathematics teacher. His father died young, so he helps his mother take care of the rest of his siblings. Currently in a relationship with the biology teacher, Kocho Kanae.

Agatsuma Zenitsu: First year high school student of Kimetsu Academy. Lives with his foster parent Juguro. A bit of a shameless person when it comes to love, which disgusts some people. If he acted more natural, maybe the girls would come to see his earnest and honest personality?

Kamado Tanjiro: The oldest child in the Kamado family. Wears the family earrings to honor his father. He also helps in his family's bakery store, waking up at four in the morning to bake bread.

 

[DeeplyoftheWorld]

Coming back from Final Selection, Tanjiro and Takeo were exhausted, tired, and happy.

Nearly two years of training, and they made the first step. It was humbling in a way. Despite all their hard work, their journey only began.

Seeing Urokodaki's home at the horizon, Takeo gained a burst of energy and started running. Tanjiro followed him, and the first person they saw was Nezuko.

Urokodaki and Hanako stood close behind her, but the immediate bone-crushing hug from both brothers had everyone falling to the ground.

Their emotions burst from the seams, and the Kamado siblings cried together. Urokodaki kept his mask on, but his scent of overwhelming happiness did not go unnoticed by Tanjiro.

The brothers cleaned themselves up as Hanako and Urokodaki prepared a large meal for everyone.

"She woke up the day before you both came back," Urokodaki said.

They all sat on the floor, eating their meal with unending appetite. Hanako kept chastising Takeo for his poor manners while Tanjiro's attention was caught by Urokodaki.

"Do you remember when the Ice Hashira spoke about blood demon arts?"

Tanjiro nodded. Takeo's ears perked up in interest.

"I believe Nezuko gets her energy from rest and sleep. But, I wouldn't call it a blood demon art. She is changing herself in a way no demon has ever done."

Urokodaki sighed with all the concern and confusion of a man his age. "Regardless, I truly have hope for you all, and that the answers you're looking for will be found."

Takeo turned to Hanako. "What will you do?"

She answered immediately, as if prepared for his question. "I'm going to the Butterfly Estate to learn more about medicine. If I can't help fight demons or travel with you, then I want to help Nezuko in my own way."

Tanjiro smiled, elated to see his sister pursue something that wouldn't result in death.

Takeo's face scrunched up. "When did you even learn about stuff like that? I thought you were just cooking and cleaning."

Hanako raised her hand and smacked Takeo's arm. Ignoring his grunt of pain, she spoke again. "Urokodaki taught me, thank you very much! I can read and write better than you."

"Hah? No way! What do you think, Tanjiro?" Takeo objected.

He took no sides, only placating his younger siblings by hugging them again. Admittedly, Tanjiro's presence was comforting, so their argument died before it even began.

-

The swordsmith who crafted Takeo's and Tanjiro's swords finally made his way to Urokodaki's house.

Haganezuka Hotaru, an eccentric and overly energic swordsmith, presented the blades.

"See that?" He pointed at Tanjiro's forehead. "A sign like that is a blessing! A child of light, just like the ore that bathes in the light of the sun. Please, take the blade!"

Takeo, miffed at being ignored, immediately grabbed the one in front of him.

His blade turned black.

Tanjiro followed next, holding his sword.

It also turned black.

The house was silent for a moment, then Haganezuka exploded.

"Where is the red? The bright red blade? Why is it just a sad shade of black?" He grabbed Tanjiro, shaking him back and forth, accusing him like a criminal.

Haganezuka cried to himself. "What's wrong with you? What happened?"

Takeo's expression turned stony and he pushed the middle-aged man away from his brother. They stiffly thanked him.

Haganezuka left with a huff, the chimes on his hat becoming softer as he walked away.

"Are all swordsmiths that insufferable?" Takeo asked Urokodaki.

His mask bobbed side to side, hiding a grin. "No. Hotaru has always been one of the oddest swordsmiths I've met. Sabito nearly beat him to a pulp once."

As Takeo and Tanjiro prepared to leave, Urokodaki presented them a wooden box.

Fitting on Tanjiro's back comfortably, they watched as Nezuko shrunk herself to fit in the box.

"The material is of a special wood that's extremely durable and light. As long as your sister hides in it, she can travel during the day safely."

Thanking Urokodaki, the brothers stepped out, hugging a tearful Hanako, and starting their first journey as demon slayers.

-

Their first demon, which Takeo aptly called the 'swamp demon,' was defeated with less effort than anticipated.

First, its appearance surprised Tanjiro. Coming underneath the ground to ambush him, Tanjiro swiftly pushed away the boy who accompanied him, and unleashed an attack.

Hinokami Kagura: Dance

The downward slash burned the demon. He screamed in pain, and two more versions of himself spawned from the ground, set on killing Tanjiro. The rage-induced concentration made them sloppy, and worse, caused their demise.

Hinokami Kagura: Clear Blue Sky

Takeo performed his own ambush and sliced the demon's neck off.

Breathing heavily, he walked slowly to Tanjiro. Nezuko, already out of her box, came over to pet Takeo.

"Stop that!" Takeo dodged like a cat.

Confirming the demon's death, they immediately set out for their next mission.

The Asakusa area within Tokyo was highly urbanized and modern. A drastic change of pace from their old village, the atmosphere overwhelmed them. With the night illuminated by the lights of the city, Nezuko stood next to them, dozing as she walked.

Walking around the streets of the city, Tanjiro and Takeo absorbed everything around them. A boy and his box-wearing brother would normally be a odd sight, but the bustling of the city paid them no mind.

Finding a spot next to an empty udon stand to calm down and relax, Takeo couldn't help but be amazed.

"The city's amazing! It's so bright!" He said, desiring to experience more.

Tanjiro wanted to agree, but held himself back. They had a mission to do, but the crows gave them very little information to work with.

In that moment, he nearly choked in disgust. Covering his mouth and nose, Tanjiro swayed. With Takeo's help he slowly stood up. Tanjiro began walking, then he started to run, trying to find the vile scent. It bore the same resemblance as when his family was killed.

The man responsible for their family's tragedy was undoubtably here.

Takeo, seeing his brother so intently focused, chased after Tanjiro and concentrated on the people around him. Some were in a rush, some were idle, and one man had piercing red slits for eyes. They locked eyes and Takeo instinctively gulped in fear and anger.

Tanjiro, sensing the rush of fear in his brother, saw the man his brother was looking towards.

Wearing a western suit and hat, the man's eyes gazed upon them. He carried a young girl in his arms.

In a flash, several things happened.

Tanjiro and Takeo sprinted towards him, ignoring the looks they received. The man turned back and kept walking, but not before scratching and injecting a person's neck with drops of his blood. The victim collapsed and convulsed in agony, causing a panic among the crowd. The victim bit the neck of the nearby woman, and she shrieked.

Takeo jumped towards the newly turned demon and held him at bay while Tanjiro bandaged the woman's wounds.

Tanjiro screamed to the sky, promising to hunt Muzan and personally cut off his head.

The police started to arrive, but not before Tamayo approached and raked her arm, setting off a flowery illusion around them. Without speaking a word, Tamayo and Yushiro helped the brothers and the demon get away.

Tanjiro and Takeo returned to the empty udon stand, taking Nezuko with them. They saw Yushiro waiting for them, and they followed him.

"You waited for us?" Takeo asked, his hand resting on his sheath.

Yushiro scoffed, barely able to tolerate their presence. "I was instructed by my lady to wait for you, but it's best to hurry and get to the house as soon as possible."

He muttered to himself, expressing his personal grievances. "I can't believe that guy told the truth. Though, the girl is an eyesore."

They both heard the demon's words.

Tanjiro remained confused. Who was the eyesore? His beautiful, kind sister?

Takeo snarled, punching Yushiro in the face. The demon glared, ready to teach Takeo a lesson, but he took a deep breathe.

This was all for the sake of Lady Tamayo.

Arriving inside the safehouse, the Kamado siblings introduced themselves. Tamayo, sitting next to a bed, tended to her patient. The patient was the same woman that Takeo bandaged, and she slept on the bed, breathing steadily.

"She is fine," Tamayo said. "Unfortunately, I had to lock her husband in the underground cell."

"Shouldn't it be impossible for you to resist human blood?" Takeo bluntly asked.

Tanjiro apologized as he tugged on Takeo's ears, prompting a yelp from the younger brother.

"First, I should introduce myself," she said, forcing everyone to a different room. "I am Tamayo, and the man who guided you is Yushiro. As for your question, I've altered my body greatly, and even removed Muzan's curse. Because of that, both Yushiro and I do not feed on humans and only require blood."

Tanjiro nodded, accepting the explanation. Their scent, even with his enhanced smell, was more subtle than a normal demon's scent. If he passed by them at a busy street, he wouldn't be able to recognize their scent immediately.

Opening the box, Nezuko sprawled herself on the ground. Takeo berated Nezuko for laying around disrespectfully.

Tamayo smiled before continuing. "While we get by with blood, Yushiro requires even less than I do. It was after many years that I was able to turn Yushiro into a demon."

That grabbed the brother's attention.

"I thought only Muzan could turn others into demons?" Tanjiro asked.

She nodded. "That is essentially true, and it is his blood that carries the curse and ability to turn others into demons. Yushiro is the only person I've been able to turn into a demon after centuries."

Takeo's eyes bulged. "How old are you?"

Yushiro punched Takeo in the stomach, relishing the pain on the boy's face. "Do not be so crude to ask a lady her age."

"Do that again, Yushiro, and I will make you regret it," Tamayo frowned.

He straightened up, embodying the image of a well-behaved boy.

"I'll be clear. I do not intend to make more demons, and it is only if I have no other choice to save a person's life that I ask if they wish to be a demon. Otherwise, I will not do it."

Tanjiro understood, and he sensed no deceit or manipulation on her part. Tamayo radiated a type of wisdom singed with sorrow.

"Do you know if there is a way to restore someone's humanity after becoming a demon?"

Tamayo thought for a few moments, then she nodded again.

Eager to know more, Tanjiro got closer, desperate for the answer. Yushiro moved to throw him, but Takeo wrestled with him, causing the two of them to roll around, neither gaining an advantage over the other.

Tamayo stared at Yushiro with disappointment. "Yushiro, I told you, didn't I?"

Shoving Takeo off, he returned to his previous position, sitting properly.

Facing Tanjiro, she spoke again. "No matter the illness or ailment, there is always a cure or treatment for it. However, at this point, I do not have a way to reverse the transformation. To that end, I will need your help."

Takeo sat up, his hands trembling from excitement. "We'll do anything!"

Raising a finger, she listed her first request. "I will need to study your sister's blood. As I understand, she has not consumed the flesh or blood of a human. Demons that do not feed themselves unquestionably go berserk after a certain point. This condition of hers is a rarity comparable to a miracle. In studying her blood, I believe I'll get closer to a cure."

She sighed. "My second request is already being fulfilled at this point, but it never hurts to have more samples. I need blood from strong demons. A stronger demon has more of Muzan's blood, making it invaluable to research, but I understand it is not an easy task to complete."

Both brothers readily agreed without hesitation.

"Someone else is also helping you?" Takeo asked, noticing Tamayo's phrasing of her second request.

She laughed lightly as if someone told her a joke. "Yes, and he was originally the one who mentioned your sister. We have not had many opportunities to meet again, but we exchange letters."

Takeo racked his brain. There were only so many people that knew about Nezuko.

"Was it Murata?" Tanjiro asked.

"The very same," Tamayo confirmed. "It is because of him that I decided to invite you inside, if only to confirm his words."

Pulling out a few needles, she handed some to both Takeo and Tanjiro. "Collect the blood with these, and our cat, Chachamaru, will deliver it to us."

Pocketing the materials, Takeo looked towards his brother "Simple enough. Right, Tanjiro?"

Tanjiro and Yushiro moved in tandem. Tanjiro pushed Takeo and Nezuko away as Yushiro grabbed Tamayo.

The house violently collapsed in a mess of wood and debris.

 

[DeeplyoftheWorld]

With urgency in his steps, Murata followed his crow to the borders of the city.

He did not anticipate this change. Focusing on his running, he stopped from overthinking. It did not do good to dwell on things that already happened.

Surrounded by the thick forest and trees, he made his way to the meeting spot. Taking in a deep breath, he paused, silently waiting.

From the clearing, Tamayo and two other people came out.

Her tight expression and tattered kimono showed signs of desperate escape. The two people beside her fared no better. The man was breathing heavily from carrying the woman, and while the woman did not look tired, her constant trembling was easily noticeable.

"What happened?" Murata hurriedly spread out his supplies, tending to their immediate needs.

Tamayo fell to the ground, her voice broken. "Muzan's dog found us. Yushiro stayed behind while we fled."

"Muzan's dog?" Murata asked, already expecting the answer. Surely, Akaza was sent to capture them.

"Kokushibo," she spat the name with venom.

Murata's brows furrowed in confusion. Evidently, Tamayo had history with Kokushibo. But, even more puzzling, Muzan sent Kokushibo for a task like this?

Why now?

"How powerful is he?" He asked while feigning ignorance. The only information Murata had about Kokushibo were on the pages of a book that didn't exist. To actually meet the man and observe his strength meant certain death.

Clumping the dirt with her hands, the veins in her hands pulsed with anger. "Upper Moon One."

Helping Tamayo up, Murata carried her. Keizan, likewise, carried his wife, and they began running further away from the city. Murata's crow led the way, pointing them towards the Ice Estate.

"How did you escape?"

-

While the ambush on Tamayo and the Kamado siblings ended with no casualties, Yushiro and Tamayo knew it was time to move to a different safehouse.

The brothers and their demon sister left, vowing to help Tamayo in her research. They were well-meaning boys, and it warmed her heart.

Having lived for several centuries, Tamayo procured several houses and hideouts.

After relocating, Tamayo tried to make a breakthrough. While she could not cure the newly turned demon from Asakusa, the blood samples Murata gave her were put to good use, and she was able to break the man out of Muzan's control.

It was much faster than the process she used to turn Yushiro into a demon, which meant that with more of Muzan's blood, she could find additional weaknesses and solutions.

Nakashima Keizan thanked her with all his heart, his wife beside him in a kneeling position. They offered to help her in anything, and while Keizan's wife was a normal human, she offered her assistance regardless.

Nakashima Yukiko was a quick learner, and adapted to her new life quickly.

Just like Yushiro, Keizan did not require very much blood. Even so, his blood demon art started developing at a good pace, and progress was being noted by Yushiro.

"He has a blood demon art suited for battle," Yushiro grumbled.

Holding one of the flesh seeds in his hand, Yushiro threw it in the air and watched as it exploded and transformed into a large spike. He pocketed several more of the flesh seeds, hoping to test its limits further.

Taking notes, Tamayo observed its effects. "Fascinating. The spikes can be used to restrict movement and mobility."

She went to take more notes. Then, without warning, Yushiro collapsed, his face flushed with sweat. Tamayo went over to check on him, but he pushed her away.

The urgency in his voice startled her. "Lady Tamayo, you must leave now!"

"Yushiro, what's wrong?"

He gritted his teeth, and his hands bled. "Just leave! The illusion is breaking!"

Applying his talismans to Tamayo and the couple beside her, he rushed out of the house, scouring for the threat.

With the night still young, Yushiro narrowed his eyes. In front of him was a demon with six eyes and a sword by his hips.

He radiated the aura of a monster. Yushiro's chest began to ache and his hands trembled.

Upper Moon One

"An illusionary blood demon art?" Kokushibo observed and remarked to himself. "It's potent. Even with my eyes, I cannot see through it easily."

Hiding several of the flesh seeds within his hands, Yushiro worked to stall as much as possible.

He rid himself of any pretense of escaping. As long as Lady Tamayo and the others fled, that would be enough for him.

He mentally apologized before steeling his expression.

"Who are you, and why have you come?" Yushiro adjusted himself, masking his fear and preparing his posture.

Kokushibo stood still, confusion tainting his expression. "You do not know me?"

Truthfully, he felt slighted. He was Upper Moon One. Even new demons were vaguely aware of the hierarchy.

"Not a clue, dumbass!"

Kokushibo did not react to the insult. "You hide your fear well, demon."

Unsheathing his sword, he introduced himself. "Very well. I am Kokushibo. His Lordship has sent me to investigate and capture the traitor Tamayo. Yet, I see only you. Is that merely your blood demon art or has she already escaped?"

"Like hell I would tell you!" Yushiro slapped a talisman on himself, hiding his presence. Next, he threw the flesh seeds into the air as they exploded.

With a practiced swing, Kokushibo let out a breath.

Moon Breathing, First Form: Dark Moon, Evening Palace

In a single strike, several crescent moons were released, instantly destroying the protruding spikes before they could hit Kokushibo. Concentrating on his surroundings, he struck out his left arm, the hand coming in contact with flesh.

A choked sound ensued and the talisman on Yushiro broke, which revealed him. Kokushibo's grip on Yushiro's neck tightened.

Focusing his eyes, Kokushibo peered into Yushiro's biology.

"Abomination of Tamayo," he stated. "I will take you to His Lordship himself. Pray that he will find a use for you."

Sensing a lack of demonic presence in the area, Kokushibo walked away as he held Yushiro tightly. He could search for Tamayo later. For now, His Lordship had just received a new experiment to focus on.

-

Days of traveling later, Murata and the others arrived at the Ice Estate. He sent a message in advance to pause all visits or sparring sessions.

The official reason was for renovation. In truth, Murata already prepared a separate area of the estate for Tamayo and her research. Originally, this was so Murata could help ease the demon doctor's assimilation into the Demon Slayer Crops, rather than being thrown straight into the Butterfly Estate.

Granted, he wanted the transfer to be done at least a year ago after the first meeting with Tamayo and Yushiro. At least now, he could put it to good use.

In his personal opinion, it was a bit useless now.

Murata wanted to inform Kanae of the situation and have Tamayo immediately working in the Butterfly Estate. Unfortunately, the master told him to wait. While frustrating, Murata would not disturb the master's order.

The pieces are coming together. Once Nezuko is known, then the rest can fall into place.

Putting away the letter, Murata sighed. The Ubuyashiki premonition made no sense.

-

On the second floor of the manor, a large room was altered into a makeshift laboratory. Tamayo, alongside her assistants, were conducting further research.

It was a good distraction from the loss of Yushiro. She would not want to admit it out loud, but his presence was a bright light compared to the dimness of her past.

The fact that she was able to help someone as a demon filled her with hope. Unfortunately, she could only pray that Yushiro would be strong enough to resist and sabotage any of Muzan's goals.

She knew the man. If only to satisfy his childishness, Muzan would torment and dissect Yushiro rather than employ him for any mission.

Muzan's paranoia was well known to Tamayo, and she was aware of how often it backfired on him.

She could write an entire book about it. With their history, there were many things to tell.

She sardonically laughed out loud.

"Is something wrong?" Yukiko asked.

Tamayo kept any snappish remark to herself. "Nothing wrong. However, we will need to continue testing your husband's blood demon art."

"Of course," Yukiko nodded. "I'll go get him from the courtyard."

-

Keizan, meanwhile, stared at the stars as he regained his stamina. He had just spared with the Ice Hashira and lost more times than he wanted to admit.

Apparently, Murata was only average amongst the hashira. Though, Keizan would have to meet the others for himself before he believed Murata's words.

While his regeneration was slow compared to other demons and his physical strength left a lot to be desired, his blood demon art held potential.

Murata complimented it. "Against a demon slayer, your ability is is useful. A good trap or a well thrown seed could permanently disable someone. Then, it would be an easy feast."

Keizan shuddered. "Please don't describe it that way."

"Fair enough. Take it from me though. Against even a demon, your skill would be troublesome and something to watch out for," Murata said.

Nobu flew from the north, the crow's voice laced with alarm.

"Retired! Retired!"

Plucking the letter from his crow, Murata cursed.

"What happened?" Keizan asked.

Murata crushed the letter in his hand.

Sound Hashira, Uzui Tengen, retired, due to loss of limb from Upper Moon Four!

Wind Hashira, Shinazugawa Sanemi, in serious condition, recuperating in the Butterfly Estate!

 

[DeeplyoftheWorld]

Sanemi and Tengen were a duo that most people didn't expect.

Of course, as equals and peers, they were respectful to each other and willing to get the mission done. But beyond that, they had no deeper relationship.

The ironic thing in the Demon Slayer Corps was that despite the shared camaraderie in fighting demons, a meaningful friendship was difficult to maintain.

With high attrition rates and team missions being based on several factors, it was easy to feel alone. Depending on one's luck, a person could find themselves completing solo missions for years at a time, if they survived that long.

The hashira fared better with those issues, but since their ability were leaps and bounds above the average demon slayer, they were relegated to solo missions, barring extremely rare cases.

The current mission fell into the rare category. This situation was a special request put by both Tengen and Sanemi that the master reluctantly approved.

As a result, they spent most of their time together investigating a certain demon.

They trained together. They ate together. They worked together.

In the past year, Tengen had spent more time with Sanemi than with his wives. A fact that he often lamented privately.

Sanemi could not care less. Though, he did wish to be in the company of Kanae rather than the Sound Hashira.

Over time, they developed a bond deeper than friendship, but not so intimate as romance.

Regardless of their personalities, Wind Breathing and Sound Breathing mixed well. With Sanemi's tricks and Tengen's unorthodox ways, fighting together became more and more natural.

Unfortunately, while their teamwork improved, Sanemi's lack of patience hindered their investigations. In addition, Tengen's information network was devoid of his wives, which further slowed down progress. He did not want to risk their lives against someone like his father.

Finding themselves in a lull, Sanemi complained.

"At this rate, we'll never find the bastard," downing his drink, Sanemi ordered another.

Tengen scoffed. "Calm down, you brute. I have a good feeling about the next place."

-

Tengen's village was a hidden and old secret. They were not the only family of ninja in the history of Japan, but in the Taisho era, they were one of the few remaining.

The village was empty, with a seemingly unnatural mist clouding the area. Tengen remembered brighter days, with children running around and old people walking peacefully.

Well, as peacefully as retired spies and assassins did.

Strangely, other clans of ninja were possessed by a fervor similar to his father. Not only did the decline of their profession cause a panic, but the sudden change in lifestyle proved harsh for many of the people, and most abandoned the path or died while training.

Shaking his head, Tengen stuffed his old memories away as he observed the buildings.

Old blood stains covered some of the wooden structures. It appeared as though a massacre swept the area. If his father became a demon, then the first place he destroyed was likely the village.

There was no need to continue the bloodline if one was immortal. They were the bloodline.

Tengen muttered to himself. "I don't know why I waited so long to come back."

"Because I bet it brings back shitty memories." Sanemi said, seeing Tengen's tight expression. Sanemi wouldn't want to come back to his own village either, after everything that's happened.

Preparing a running start, Tengen waved him off. "It matters not! Let's continue."

Sprinting into the distance, Sanemi followed.

-

"Why are there so many damn stairs to your home?"

Grumbling to the top, the two hashira stopped in front of the gate.

"The first head of our clan wanted our estate to be the highest in the village. It also helps with training," Tengen explained. Their crows flew above them, scouting for anything suspicious.

"That's strange. It's locked." Tugging at the chain and its lock, Tengen began lockpicking.

"Step aside," Sanemi commanded, bringing out his sword.

Tengen half-heartedly chopped Sanemi's head. "Idiot! This is still my ancestral home! You want my family's spirits to haunt you?"

With a light glare, Sanemi mumbled to himself.

Finessing the lock and throwing out the chain, Tengen opened the gates to his family home.

When they entered, the gate closed behind them.

Standing in the middle of the yard, they saw a figure sitting right before the entry to the manor itself.

A man that looked like Tengen stared at them.

Upper Moon Four

"If it isn't my son and his rabid monkey," Tetsuji said dispassionately, as if he were discussing the weather.

"Did you decide to kill the rest of our family and village before or after you became a demon?" Tengen asked. His face was engraved with unrelenting focus and a burning fire danced in his eyes.

"Does it matter?" Tetsuji lazily said. "I killed them as I pleased. Good timing as well. Once I got rid of your brother, there was no one else left to inherit the Uzui name."

Tengen shook, his blades already unsheathed in his hands. "I pray you find torment in hell. There are no words to describe your cruelty."

Sound Breathing, First Form: Roar

Jumping towards his father, Tengen brought down his blades. Tetsuji blocked, already ripping an arm to create his blood weapons.

Wind Breathing, First Form: Dust Whirlwind Cutter

Sanemi closed the distance, unleashing his own attack to cover Tengen's blind spots.

The area groaned from the ensuing collision. Trading blows, Tengen and Sanemi clashed with Tetsuji. Covering each other whenever a weapon flew towards them, both hashira maintained their momentum.

Suddenly, Tetsuji kicked Tengen harshly.

Crashing through the gate, Tengen kept falling farther and farther. Seeing his father charging straight at him, Tengen's eyes widened.

Pulling out a bomb, he let it explode as it propelled him down to the village. Throwing out several more, he swung his weapons together to disorient Tetsuji.

Wind Breathing, Sixth Form: Black Wind Mountain Mist

Sanemi chased down the two as he unleashed another attack.

Regrouping, Tengen and Sanemi fought side by side, putting the pressure on Upper Moon Four.

Frustrated with his lack of progress, Tetsuji exploded both his arms. He quickly regenerated but the pools of blood turned into a pinprick of needles.

Nicked by several needles, Tengen immediately noticed the effects.

"It seems not even my most talented son is immune to the poison," Tetsuji said, picking up on the slight hesitation in Tengen's expression.

Tengen laughed heartily, his amusement echoing in the quiet village. "Dumbass! You think this stuff works on me? Tut-tut, I'm disappointed in you, father."

"Don't bother hiding it. I can sense it."

Wind Breathing, Second Form: Claws Purifying Wind

"Sense this, bastard!"

Tetsuji dodged the attack. With a counterattack, he slashed Sanemi's arm.

The rich marechi blood wafted in the air, causing Tetsuji's eyes to narrow and his pulse to quicken.

Flushed with heat and excitement, Tetsuji stared back at Sanemi.

"You...are marechi?" Laughing to himself, he started clawing at his arms. "What a beautiful night!"

Sound Breathing, Second Form: Flashing Chains

Tengen mounted another strike at his father. Busy with Sanemi's advance, Tetsuji found himself on the defensive again, his neck coming into contact with Tengen's blade.

Turning his foot into a curved axe, he kicked upwards, attempting to impale Tengen.

Tengen retreated, allowing the demon's neck wound to heal back up. Sanemi sliced again, but Tetsuji parried and summoned several more weapons.

With both hashira able to keep up, the battle began turning into a temporary standstill. Tetsuji could kill them given enough time, and it was only a matter of time. Tengen and Sanemi slowed slightly, the collective wounds beginning to pile up.

Tengen racked his mind for another idea. It didn't look good, and if one of them let down their guard for even a moment, the demon would capitalize on it.

The battle continued, Tengen throwing out whatever he had on hand, and Sanemi going for cheap shots when able. Their speed steadily slowed and their stamina waned. Tetsuji's endurance, on the other hand, was commendable but the drunken feeling and the constant barrage of attacks made him sloppy.

Coming up with a last ditch effort to end the battle, Tengen rushed again.

Seeing the nonverbal sign, Sanemi kept engaging the demon, keeping him distracted.

Sound Breathing, Third Form: Spinning Flashing Rumble

With speed that made him look like a whirling drill, Tengen aimed straight for his father's chest, impaling him.

Wind Breathing, Eighth Form: Primary Gale Slash

Digging into the shoulder towards the neck, Sanemi poured his strength into his sword.

Tetsuji found himself in a rare moment of dread.

-

It was not long after Tengen left that Tetsuji found himself in a bind.

Tengen's younger brother was learning well and adopted the mannerisms and tactics as his father. Unfortunately, he did not possess as much latent potential as Tengen.

Tetsuji could sense the potential of each of his children. It was an instinctual skill, and while Tengen claimed to have no talent, his hard work and potential saw him reaching heights no other child could.

In a fit of rage unlike him, Tetsuji murdered his last son.

Tetsuji's last surviving wife committed suicide shortly after, and for the first time in his life, he shambled mindlessly, lost in purpose and meaning.

After six centuries, this was what the Uzui bloodline amounted to?

It made him want to hunt down Tengen himself.

During a dark night, Tetsuji found himself approached by a horrifying being. The man pricked himself with his blade, collecting a small pool of blood in his hand.

"Bloodline?" Kokushibo thought for a moment, sheathing his sword while giving the blood to Tetsuji.

"If His Lordship is willing, then becoming a demon is the answer. Only then will your concerns of lineage and bloodline disappear. As a demon, you can continue honing your skills for centuries."

With a clear solution to his problems, Tetsuji drank the blood greedily. He convulsed and writhed in pain, the transformation into a demon taking over a day.

For once in his life, Tetsuji felt enlightenment. He suddenly understood why the monks went to torturous efforts to find such clarity.

In Tetsuji's mind, this sense of clarity was only possible by becoming a demon.

He would never regret it.

-

"I will not lose! To be bested by children!"

Roaring desperately, Tetsuji detonated his body, leaving only the head and bits of the torso intact.

The blood turned sharp, scratching Tengen and Sanemi. A perfect representation of a death by a thousand cuts.

Regenerating his arm only to turn it into a blade, he cut off Tengen's leg, causing the demon slayer to cry out and lose balance. Tengen made to grab something, then he fell and collapsed in pain.

Running away, Tetsuji fled as the first signs of dawn advanced.

Sanemi, initially torn between chasing the demon or helping Tengen, immediately rushed back to Tengen, trying to stop the bleeding.

"You'll be fine, damn it! Just stay alive! Stem the flow!"

Tengen kept his eyes opened, but his consciousness waned. Despite his closeness to death, he smiled triumphantly. "Don't...worry. I got...something."

Sanemi kept cursing. "Stop speaking nonsense, and focus on your breath!"

The kakushi arrived, herded by Tengen's crow as they assessed casualty damage.

-

Leaving the medical ward, Murata walked into a room prohibited by most people.

Kanae was inside, peering into journals and working on a medical experiment.

"Ah, Murata, it's good to see you! Did you talk to Sanemi?" She asked, a cheer in her step.

"I did, but since Tengen's at his estate, I couldn't ask for his side of the story. Did he tell you anything?"

She hummed, then nodded, a manic gleam appearing in her eye.

"Yes, but even better, he retrieved samples of his father's poison. With a cure in sight, Sanemi will be ready in no time!"

Murata raised his brow, delighted but wary by Kanae's excitement.

"I'll be able to get back into my duties as well," Kanae remarked. "This Flower Hashira is blooming once again!"

Murata nodded. Now he understood.

Bidding her a farewell, he left, writing a letter to Tamayo.

 

[DeeplyoftheWorld]

The next few weeks passed by like a gust of wind.

Kanae resumed her post as Flower Hashira, and Sanemi began recovering from his battle. They both began spending more time together; Sanemi was put on quarters while Kanae started intense physical training again.

Tengen retired due to the loss of his leg. His wives were increasingly worried about him, especially after losing an eye, but having a leg torn off was the final straw.

Sitting inside the Sound Estate, Murata listened to Tengen's voice.

"To know that my father is still around and killing innocent people, it enrages me," Tengen sighed.

Feeling a phantom pain, he massaged his stump. "Even though I nearly died, I don't regret it. Fighting against my father filled me with joy. Does that make me a bad person, to want to hurt and kill my father?"

Murata shook his head. "Since he willingly chose to be a demon, there is no room for mercy. Maybe sympathy, but from what you've told me, he was a cruel man even before becoming a demon."

Tengen laughed, a low sound that rumbled from his chest. "I figured you say that."

They sat in silence for a few moments before Tengen spoke up. "This is selfish of me, but since I'm out of duty, I don't want my wives to work while I stay here. They're coming back now, but having worked in the Entertainment District, we narrowed down a potential demon living in the Kyogoku house."

"I thought you were too busy hunting down your father to help them?" Murata asked.

"I was, but the muscle mice were there. I'm the only one that can understand them, which is why I even know. I prepared some notes you can take, but I'm entrusting it to you."

Murata internally groaned. Tengen's journey to the Entertainment District was the perfect catalyst for awakening Tanjiro's mark.

It wasn't a simple matter of training Tanjiro to awaken the mark. Indulging in an memory, Murata recalled that achieving the mark was like being sifted.

In other words, the difference between those who manifested the mark and those that didn't was death. Mere training couldn't replicate a life or death battle.

Unless one was Gyomei. But, he was one of a kind, so the problem was still there.

Murata rubbed his forehead, the sudden sting bringing him out of his head. Tengen retracted his hand, having just flicked Murata.

"Don't get all gloomy on me," Tengen said. "I still plan on doing things, but I'm not fighting."

His face lightened up, an idea stirring in his brain. "Say, since you have a habit of finding talented people, try to find someone that can benefit from my teachings. They don't have to be flashy or anything, but if they can learn from me, that would be enough."

"Are you absolutely sure?" Murata asked. He had only one person in mind, and they would get along like oil and water.

Yet, since they both had an enhanced sense of hearing, maybe it could work.7

Tengen scoffed. "Don't give me that look! I can handle myself just fine."

"Then of course, I'll try," Murata answered. It wasn't Tengen he was worried about, after all.

The two friends moved to lighter topics before being interrupted by Nobu.

"Summoned! The master wants to see you!" He cawed.

Murata acknowledged his crow, and he stood up. Grabbing Tengen's hand, he helped him up and gave him his crutch.

"Don't let me hold you up," Tengen said.

Murata nodded, and he departed.

-

"It's good to see you again," Kagaya rasped. The master sat on the engawa, surrounded by two of his children. The moon was full and bright, illuminating the garden.

Murata stepped in, putting himself in a kneeling position. He went to say something, but the sliding door opened again.

Makomo showed up, kneeling next to Murata as they waited for the master's command.

"There's been a situation stirring at Natagumo Mountain. I trust that you will work together to fight the demon."

"As you wish!" They both said, picking up their sword and leaving.

Running towards the destination, Murata racked his mind.

Natagumo Mountain sounded familiar, but any information about it evaded his brain like smoke in the air. He couldn't help but think how strange it was for the master to personally ask two hashira for a task like this.

But, it had been a while since he was assigned a mission with Makomo. She lifted her head, staring into the sky, then increased her pace. Murata kept up, and they approached a mountain surrounded by forests.

"I'll go for the top while you search around the base," Murata offered, coming up with a quick solution. She wordlessly nodded and they split up.

-

When Hashibira Inosuke told Gonpachiro and Tatekato to go ahead and let him take care of the large demon, he didn't expect to actually lose.

With anything demon-related, if one sword didn't do the job, then use another one. If one cut or slice didn't work, keep slicing! Keep up the attack, and don't let the demon rest for a single moment.

Yet, the large demon kept regenerating, and he roared, the sound of it causing the trees to visibly vibrate.

Beast Breathing, Third Fang: Devour

Raising his swords, Inosuke sliced from both sides of the demon's neck, desperately trying to saw it off. The effort gnawed on his strength, and the effort became unbearable.

He was too slow, and the demon grew two more arms to grab the swords and throw them away. The demon's other arm gripped Inosuke's head in a vice, and the pressure began dulling his senses. His vision became to blur as pain built up, and Inosuke saw flashes of his friends and a crying woman.

The demon's last arm, primed in a position to punch off his head, never happened.

The hair on Inosuke's skin rose up. He shuddered from the small chill and realized that all of the demon's arms were slashed away. Falling to the ground, he looked up and saw a plain man.

Ice Breathing, Fourth Form: Ice Cutter

Watching the man tear through the demon and cut off its head with no difficulty, Inosuke realized something.

He had a long path ahead to get stronger, but if he could beat this man, then it would prove his strength!

"Fight me!" He cried out as the man looked back at him in pity.

It hackled Inosuke's nerves.

"You beat that demon, but if I beat you, then it proves that I'm the strongest!"

Before he said anything else, he found himself tied up to a tree.

"Don't leave! Come back here, damn it!"

The man shook his head and muttered to himself as he ran away. "Can't believe this is already happening..."

"Get back here!"

-

Murata wanted to slap himself once. Then, slap himself again. And again.

Obviously, this was the one and only Natagumo Mountain.

For Tanjiro, this was a pivotal moment when his life flashed before his eyes. Remembering a memory of his father, he was able to unleash the first form of Hinokami Kagura against Rui.

However, since he already began practicing Hinokami Kagura, the events on Natagumo Mountain lost a lot of its significance. Regardless, Murata didn't want to take his time, so he left Inosuke behind and kept an ear and eye for Tanjiro, and by extension, Takeo. They were undoubtably going to fight together.

Running past the endless trees, he finally came upon an open area. Tanjiro was collapsed on the ground, Nezuko was tied up, and Takeo was nowhere to be found.

The demon, Rui, holding his head with a thread of web, walked towards Tanjiro.

"Did you really think that would work?" Rui mocked. "Did my trick delude you into joy? I don't what your sister did, but you pissed me off. I'm done with this."

Preparing numerous threads of web, Rui began unleashing a barrage of attacks intending to kill Tanjiro.

Murata jumped in and cut down every thread.

Staring at Rui's eyes, Murata noticed the engraving.

Lower Moon Two

It seemed that Rui was on a spree of promotions. Maybe Muzan 'encouraged' Rui to pursue more strength.

"Another one of you barbarians. It's like you're pests standing in my way!"

Concentrating dozens and dozens of razor sharp webs, Rui threw them at Murata.

Ice Breathing, Fifth Form: Freezing Hundredfold Slashes

Quicker than Rui expected or anticipated, the threads were sliced into nothing.

Then, he felt light. His head fell to the ground, and he watched as the man spoke with the younger boy. He relived lost memories, and his last moments were spent crying for his parents.

Murata observed the crying Rui, and felt nothing. It was different in the pages of a book, but knowing that Rui killed numerous demon slayers and tortured other demons to be part of his family left him disgusted.

Tanjiro spoke to him about the tragedy of demons, and that to kill them was their final mercy. To be honest, Murata understood. But, he didn't pay attention to all of Tanjiro's talking.

He was one of the luckiest demon slayers to be born. His sister prevailed over demonic instincts. He had the goal to turn her back into a human.

Most demon slayers lost everyone they cared about to a demon. There was no going back to anything resembling a normal life. Becoming a demon slayer wasn't a career; it was a death sentence.

For one to grow old and retire? It simply didn't happen often enough.

In the distance, Murata saw Takeo running, followed by Makomo.

Her eyes widened upon seeing Nezuko, and she swung her sword. Murata blocked the blow, and they stood facing each other.

Makomo's expression turned sharp, and her voice betrayed her calmness. "Murata, did you raise your sword to protect a demon?"

He ignored her question and told the Kamado siblings to run away. Takeo hesitated as Tanjiro began standing up, but when Murata raised his voice again, they fled.

"I did, and there is a good reason for this."

"I hope you save it for Giyu as well. I received a message from him, and he and Shinobu are in the mountain right now."

Murata sighed. At least if Giyu was there, he could hold off Shinobu. Though, it was a bit overkill to send another hashira, wasn't it?

What was the master thinking?

"Giyu understands what's going on. I made sure of it," Murata said.

Makomo, realizing the implication, glared at Murata. It was one thing to involve himself, but to involve her tsuguko was an offense, especially if she didn't know.

"Then I can't wait to hear it from him. But I'll still have to go and apprehend the demon," she made to leave, but Murata grabbed her hand.

He accused her of lying. "Don't lie. You're just going to kill her, but once you hear me out, then you'll understand."

Her face promised a world of pain, but Murata continued talking, trying his best to appear as rational as possible.

In the middle of his speech, a crow cried out.

"Message! Message! Tanjiro, Nezuko, Takeo, to be brought to headquarters for trial!"

"Is that it?" Makomo looked disappointed. Murata opened his mouth, but she shushed him.

"Save it for the trial. After all, I'm not the only one you have to convince," she said.

They walked back, and Makomo pointedly kept a cordial distance from Murata.

He really wanted to drink.

If only he was back at the Sound Estate.

 

[DeeplyoftheWorld]

Goto, a member of the kakushi, shook Tanjiro and Takeo hurriedly, like he desperately wanted to leave.

"How long are you going to sleep? Get up! Get up!"

Groaning and opening his eyes, Tanjiro was greeted by the sun. It made him want to close his eyes again, but he kept them partly open to adjust to the light.

Around him were several people. They imposed on him with a terrifying presence. At first glance, they appeared stronger than any demon he's faced, bar Muzan.

He cried out for his friends and siblings. The shaking and shouts finally stirred Takeo, and he too woke up.

"Where are we?" Takeo mumbled, his eyes widening when he saw the people around him.

"What do you think?" Goto said, keeping himself in a kneeled position. "You're in the presence of the hashira!"

"Thank you, kakushi member!" Kyojuro said, his voice booming with enthusiasm. "Indeed, we are the hashira."

Pointing at Tanjiro and Takeo, he continued speaking. "And you are both on trial! It is treason to spare or harbor a demon. Thus, it is within our right to execute you immediately!"

Takeo objected instantly. "Wait, that's not-!"

"I don't disagree, but first, what do we do with Murata?" Obanai interrupted. "He's guilty, and let's not forget about Giyu."

Makomo's hands trembled with indignation. "He's my tsuguko, so it is up to me to decide his punishment. Moreover, the fault lies with Murata, who ordered him to stay silent."

Giyu, while a tsuguko, was behind Makomo and present for the trial. He remained silent and was sitting on his knees.

Tanjiro noticed that Murata was positioned away from the other hashira, thereby isolating him. He wanted to say anything to defend him, but his throat throbbed with discomfort and pain.

"Shouldn't we wait for the master first?" Mitsuri asked. "Shouldn't he be here for something as important as this?"

"We are bound by duty, aren't we?" Sabito countered, a frown etched on his face. "There are traitors and a demon that's still alive. It is our responsibility to uphold the code and rule."

Staring at Tanjiro and Takeo, Sabito offered a mercy. "However, I do want to hear the story firsthand. Why are you protecting a demon?"

Shinobu offered water to both Takeo and Tanjiro. Drinking it with the fervor of a dying man, Tanjiro cleared his throat.

"While we were gone, a demon attacked our family. Nezuko, she's our sister, was turned into a demon. But, she hasn't eaten a single human and she never will!"

"Of course you would defend her if she's family. I, for one, don't believe you in the slightest," Obanai said, glaring down at Tanjiro.

"We became demon slayers to cure Nezuko!" Takeo said. "In over two years, she hasn't killed or eaten anyone!"

"As compelling as that is," Kanae interjected, "you just repeated yourself. Words alone cannot prove such a miracle."

Tanjiro and Takeo continued pleading, but their voice was cut short by the appearance of another hashira.

"What are we doing here?" Sanemi asked. "Are we really entertaining these traitors?"

Seeing the box held up in his hand, Tanjiro and Takeo looked on with dread.

"A demon that doesn't eat humans? You know what we call that here?"

Murata moved to stop Sanemi, but Gyomei intercepted by placing a hand on Murata's shoulder. The pressure forced Murata down, causing him to wince.

Sanemi's grin turned feral as he stabbed into the box.

"A damn delusion, that's what!"

A muffled cry could be heard from the box, and with that, Tanjiro and Takeo charged at Sanemi.

Sabito held both boys back as Makomo announced the arrival of the master.

The hashira bowed together as Ubuyashiki Kagaya was assisted by two of his children. Feeling the sun on his face, he smiled.

"It's a beautiful day, isn't it? While Tengen's retirement is regrettable, it is good to see one of our own return."

"Yes, master. It is also good to see you again, and we all pray for your continued health and fortune," Kanae said.

Sanemi impatiently cut to the chase. Sheathing his sword, he addressed the master.

"Master, could you enlighten us about the demon traveling with these demon slayers?"

Even though he could barely see, Kagaya turned his face towards Sanemi.

"Ah, yes. Regarding Tanjiro, Takeo, and Nezuko, I have sanctioned their situation. I hope you all respect and agree with this decision."

A cacophony of voices erupted, and the hashira each said their piece regarding the matter.

On one side was Murata, Kanae, and Mitsuri.

The other side included Obanai, Seiko, Rengoku, Gyomei, Sanemi, Sabito, and Makomo.

Shinobu did not say anything, but remained neutral.

Sanemi summed his disagreement poignantly. "It is our sworn purpose to kill demons, not spare them. I implore you to punish both Murata and the Kamado brothers."

Pulling out a letter, the master had one of his children read it out loud.

"This is a letter from former hashira, Urokodaki Sakonji."

Makomo and Sabito looked up with surprise.

I humbly ask that you allow Tanjiro and Takeo stay with their sister, who is now a demon. Despite being a demon on the brink of starvation, her mental fortitude has allowed her to retain her humanity. Not once has she devoured a human, and this has remained true for over two years. Impossible as it is, it is an undeniable fact. However, in the event that Nezuko ever harms or kills a human, I, along with Kamado Tanjiro, Kamado Takeo, Tomioka Giyu, and Sato Murata will commit ritual suicide.

The brothers couldn't help but tear up. Giyu remained as stoic as a rock, and Murata stayed silent.

Sanemi and Sabito pointed out that despite the conviction, it did not guarantee anything. If Nezuko did kill a human, then that was one human dead that could've been saved.

The master acknowledged it, but brought up his own argument. "You are correct that there is no proof that Nezuko will not harm humans. On the other hand, we can't prove that she will attack a human. We know she has not eaten a human for two years and now, five people are willing to put their lives on the line for her. If you deny this, then a more convincing argument must be shown. In addition, both Tanjiro and Takeo have met Kibutsuji Muzan."

More voices raised, and a barrage of questions were thrown around.

"What were his abilities?"

"Where is his stronghold?"

"What was he doing?"

With a small gesture from the master, the hashira instantly quieted down.

"Muzan sent demons after Tanjiro and Takeo. It may be to simply silence them, but I don't want to squander this miraculous opportunity. I also believe that Nezuko is going through a change that even Muzan couldn't predict. Does it make more sense?"

It made sense, at least to Murata. Though, since he was already aware of these things from the beginning, it wasn't a surprise.

Sanemi spared a quick glance at Murata, then faced the master.

"If it were anything else, then maybe I could see it. But, a demon is a different story. After everything we've done to fight demons and the lives that were lost along the way, I just can't accept it!"

Pulling out his sword, he cut his arm. "Forgive me for this intrusion, master, but let me show you the ugliness of demons!"

He carried the wooden box indoors, allowing his blood to drip on the box. Seeing no reaction, he stabbed into the box, prompting a small cry to come out.

Tanjiro and Takeo looked on with anger, their voices shouting for her. Sabito still held on to them firmly, and Obanai stood right behind to keep a close eye.

Murata appeared calm, but he was praying inside. Even if he knew the outcome, it didn't change the fact that his life was on the line!

Nezuko stood up, her muzzle gone and her eyes focused on the fresh wound on Sanemi's arm. Her face flushed, and she started salivating. Getting closer and closer, Sanemi kept a tight grip on his sword, watching for any sign of attack.

After several moments of internal struggle, Nezuko turned her face away, snubbing Sanemi.

He went through several emotions in that instant, but he settled on being dumbfounded. Likewise, the other hashira were either surprised or impressed by Nezuko's fortitude.

After the children described the sequence of events to Kagaya, he allowed himself a small smile.

"I believe with that, Nezuko has demonstrated that she poses no threats to humans," he said. "Tanjiro, Takeo. I'm sure there will be some who still won't accept Nezuko. That being said, prove yourselves. Fight stronger demons, then your words will have weight."

They bowed, and both yelled to the sky that Muzan would be defeated.

It was a bit childish, and the master gently chided them to take things one step at a time. The kakushi carried them out.

Sanemi wordlessly went back outside, and they began the meeting in earnest. Giyu made his leave with permission from Makomo.

-

Moving into a large room, the master felt the presence of each hashira.

With eleven hashira, the current generation of demon slayers was powerful. Perhaps the most powerful since the Sengoku period.

Tensions fell, but there was still a fair share of hard feelings towards a certain hashira.

"There is one other thing that I would like to discuss now," Kagaya said.

Judging from his tone, it was as serious as the matter involving Nezuko.

Seeing that Murata was not surprised in the least, the rest of the hashira looked at him in varying states of confusion, annoyance, or irritation.

"I suspect Nezuko is someone that will bring immense change. However, Murata has been in contact with another ally, one who bears great knowledge and experience against Muzan."

The door slowly opened, revealing Tamayo.

Everyone stiffened, but holding his hand up, Kagaya stopped any sort of premature attack.

"She has been staying in the Ice Estate, but I want her to move into the Butterfly Estate to continue her work against Muzan. Is that acceptable to you, Kanae?"

Kanae nodded, finding herself easily accepting the proposition.

The meeting continued. An endless amount of questions were asked as Tamayo patiently offered her knowledge. Taking up the entire day, night approached.

-

Leaving the mansion, Murata collapsed just out of sight, taking measured breaths and looking at the stars in the sky.

His relationship with most of the hashira were mended, but the fact that he kept such important information secret put a damper on things.

Makomo followed Murata, seeing him mentally rest from his metaphorical heart attack.

"I know you're still upset."

"That does not even begin to cover the depths of my displeasure," Makomo kept herself calm, but the veins in her forehead and hands proved otherwise.

She sighed, and sat next to him. "I'm sad that Giyu didn't even tell me."

"I told him to be quiet about this."

"That's the other thing," she said, poking his chest. "This was something that could've been discussed with the others, but you believed it was better for it to be hidden. We are hashira. Equals, peers, and above all, a unified front. Even if it was an agreement between you and the master, it's easy to see how this could be perceived as a slight, wouldn't you agree?"

Murata did not have anything to say against her. It was a good thing Nezuko proved herself.

Without results, all he had were words and knowledge of a potential future. Murata did not believe that was enough to convince the others, which was why he went with secrecy in the first place.

Yet, he could understand that being kept in the dark proved to be more hurtful than the actual information itself.

Still, he would not regret what he did.

"In any case, you owe me and Sabito a big favor."

"What for?" Murata gulped, allowing ignorance to guide him.

Her frown could terrify a rock into combustion. "It was very unfair to manipulate Giyu like that and as a hashira, I have to look out for my tsuguko. Don't worry, we'll make sure you stay alive."

Murata prayed for a second time today. His life was on the line once again.

-

Sanemi found himself outside, his thundering footsteps illuminating his mood.

He was raging at several things, but the fact that a demon like Nezuko was allowed to live burned him.

It had nothing to do with the girl herself.

"Are you still sulking?" Kanae snuck behind him, speaking without a hint of playfulness or amusement.

Sanemi cursed. "Obviously."

"Do you want to talk about it?" She walked next to him, keeping up with his pace.

"I can't believe he would hide this from us! Just when you think you know someone-"

"He had his reasons, didn't he?" Kanae defended. "But, that's not what you're most upset about, is it?"

That much as true. Sanemi could even justify it from a logical standpoint. If Murata told him about Nezuko two years prior, he would go over and kill her without question.

Sanemi did not tear up or get emotional. He was the type of person to raise a fit or physically deal with the problem before it advanced any further.

In a quiet voice, he muttered. "It's not fair."

"Hmm?"

"I'm saying it's not fair. What's so different about that girl? 'Mental fortitude?' Don't give me that shit! If anyone had fortitude, it was my mother!"

He plopped himself to the ground, ripping out clumps of dirt. "She loved us, so why didn't she...?"

Kanae squatted next to Sanemi, wrapping an arm around him. He kept ripping out dirt as his vision blurred.
