"WAAAAAAAAAAAAHHHHH!!!" The three sisters cried on your legs as you tried to get them off of you. You had Nezuko's box on your back, you wanted to think about what Nezuko was gonna do to you yesterday before Inosuke and the others showed up. Of course, the brats distracted you from that. "ARE WE GONNA SEE YOU AGAIN?!"

"GEEEET OFFFF OF ME, YOU DAMN BRATS!!!" You shouted and threw them all off of you lightly. Tanjiro was reminded of his own siblings playing with you in the past. The girls started crying even more as Zenitsu started crying as well.  "What're you crying for?!"

"WHAT DO YOU MEAN?! THIS MIGHT BE THE LAST TIME WE SEE THEM!!" He shouted as the girls cried again and you slammed your fist to his head.

"SHUT UP!" He fell to the ground and you felt aura coming out of the box. You started walking away. "I'll make sure the three of us survive, I swear on my life."

"But then you won't be alive." Inosuke called you out and you blushed.

"Well-I...WHAT I... what I meant...." You started stuttering as Zenitsu looked at you.

"Ah, he was trying to sound cool. What a weirdo." "You're the last person I want to hear that from." You said and you all started to walk away, you saw Tanjiro crying too and patted him on the back.

"Take care, everyone!" Zenitsu shouted one last time before leaving. Due to the many people at the station, Inosuke silently grabbed your robe to not get lost and you went with it. "HUUH?! STILL NO ORDERS?! THEN WE SHOULD HAVE STAYED AT SHINOBU'S HOUSE!!"

"No, we finished our treatment, so staying there wouldn't give us anything to gain." You blocked Zenitsu's punches.

"BUT WE COULD HAVE AVOIDED THAT SAD GOODBYE!!" He argued.

"No... this way it'll be easier to move out when we get orders. Besides, the flame pillar-"YOU IDIOTS!!!" Zenitsu tried to attack Tanjiro but you blocked him effortlessly.

"Hey."

"IM BUSY NOW!!" Zenitsu shouted at Inosuke as you looked at what Inosuke was looking at.

"HEY! HEY!!" Inosuke shouted and Zenitsu glared at him.

"WHADDAYA WANT?! SHUT UP!!" Zenitsu shouted at him angrily.

"WHAT KINDA ANIMAL IS THAT?!" Inosuke saw a train and Tanjiro seemed confused as well. "This is that thing! It's the lord of the land! It slides across the earth! It's so long and overwhelming, it's gotta be! Looks like it's asleep right now, but be careful!!"

"This is a steam train, dumbass." You said and he shoved his hand in your face. "Ew!"

"SHH, CALM DOWN!!" Inosuke shouted and Zenitsu looked at him like an idiot.

"No, you calm down." He said and Inosuke backed up.

"I'LL ATTACK IT FIRST!" "LIKE HELL YOU WILL!!" You shouted and blocked him.

"Maybe it's the guardian deity of this place." Tanjiro didn't understand. "So a surprise attack may not be a good idea."

"No, like we said, it's a steam train. Do you understand the word "Train"? It's a vehicle for transporting people. You backwoods rube!" Zenitsu bluntly yelled at Tanjiro.

"Hm! Train? Then is this what the crow meant?" Tanjiro asked.

"Crow?" And Zenitsu was rightfully confused.

"GAH-!" "HEADLONG RUSH!!" Inosuke shouted as he slammed your body and his head into the side of the train, shaking it.

"STOP THAT! YOU GUYS ARE EMBARRASSING US!!" Zenitsu shouted as you threw Inosuke back.

"DON'T INCLUDE ME IN THAT, CRYBABY!!" You shouted at him and heard a whistle in the distance to see some security.

"WHAT ARE YOU DOING?!"

"THEY'VE GOT SWORDS!!"

"THE POLICE! CALL THE POLICE!!"

"I thought I told you to say out of trouble." A silver haired chick picked you and the three up and ran away with ease. Once on board, the chick dropped you and smirked at you. "I'm guessing since the seal is broken, and Tanjiro's with you..."

"Yeah, I bet you know all about it, wouldn't you, Sis." You said to your sister as Zenitsu immediately gained hearts in his eyes. You stood up and glared at her. "You've kept secrets about our family long enough, it's time to tell me what you know. Now."

"We don't have time to talk now, I'm on the clock." She said and sighed. "I can tell you later."

"That's always how it is!" You shouted at her. "You left me all alone in those woods, in the village because you couldn't handle the stress of keeping it all from me!"

"Watch it." Your sister warned you. But you held your necklace.

"You said this my grandpa gave me this necklace because he wanted me to have it, but that was all just games to YOU, wasn't it?! You hid all those secrets because YOU didn't want to relive them! It was never about me, it was always about you!" You shouted.

"SHUT UP!" Your sister shouted and the ground shook below the train. You were suddenly punched in the face by Zenitsu.

"THAT'S NO WAY TO SPEAK TO YOUR SISTER!! AFTER YOU REUNITED AFTER ALL THESE YEARS, YOU START AN ARGUMENT WITH HER?! NOT EVEN THANKING HER?! SHAMEFUL! BASTARD!" He shouted and started hitting you. Tanjiro pulled him off as you looked down and sighed.

"Crybaby's...right." You punched yourself in the face and bowed your head. "I'm sorry for yelling at you. You did it to protect me. But... I don't regret wanting to know more about my family. I deserve that at least."

"...Yes. You do. It wasn't fair of me to lie to you and put your life in danger." She said and hugged you. "I hope you can forgive me, little brother."

"Of course." You said and looked at her. "Wait, how'd you know where to find us?"

"Oh that? I heard some chatter about a silver haired man with dog ears on his head and I just came over." She said as you all looked at your head. You quickly hid your demon ears and Zenitsu shook you.

"YOU IDIOT!!" "IF YOU HIT ME AGAIN, I'LL KNOCK YOUR ASS OUT!!"

Your sister sighed and held her head. "I thought as demon slayers you'd know the rules. Your organization isn't recognized by the government."

"So, what does that mean?" You asked as Zenitsu kept getting closer to your sister.

"It means we can't actually walk around carrying swords in the open. If we tell them about demons, they won't believe us." He said as your sister looked at him. She tilted his head to the side.

"Well, you're a smart one, aren't you? A handsome one at that." She said and Zenitsu blushed with a smile.

"R-are—"NOPE!" You got in the way of the two pushed them back. "No way in hell, Sis is going for this guy?! SHE CAN DO WAY BETTER THAN CRYBABY!! I'LL EVEN TAKE INOSUKE OVER ZENITSU!!"

"But we work so hard..." Tanjiro was bummed and you sighed.

"If that's how it is, we have no choice. Let's just hide them behind our backs." You said and looked at Inosuke. "PUT ON SOME DAMN CLOTHES!!"

"If we get on the Infinity Train, we should be able to meet Rengoku." Tanjiro informers and your sister nodded.

"Ah, the guy who keeps ordering a lot. Yeah, he's in the back." She told you before she looked around. "I gotta head back to work, but we'll talk later."

"...Okay." You said and Zenitsu immediately went to follow her. You grabbed his neck. "What the hell do you think you're doing?"

"I'm going to buy the tickets as Tanjiro talks to Rengoku." He said and you picked him up and walked.

"I'll do it with you." You said and approached the counter. "Four tickets."

He gave them to you and you all walked to back. "GRAAAAH!! WE'RE IN IT'S STOMACH!!"

Inosuke shouted in the middle of the train and you got pissed at him. "WE'RE IN IT'S BELLY!! GRAAH!!! LET'S TAKE IT DOWN!!!"

"SHUT THE HELL UP!!!!!!" You shouted at him with rage.

"Isn't Rengoku a hasira? Do you know what he looks like?" Zenitsu asked and you nodded.

"Yeah, I have to remember him. He's one of the people who were desperate to kill us. Which makes me wonder why we're looking for him." You looked at Tanjiro and he looked at you with a nod.

"I'll explain it all in a minute, but Rengoku had wild hair. His smell is pretty distinct so we should be getting-"DELICIOUS!!" A shout stopped you all and you saw a man shouting, who just kept repeating "Delicious!"

"Hey, are you Rengoku?" You got to the point and he smiled at you and turned his head.

"DELICIOUS!!" He shouted and Tanjiro nodded in a bit of disbelief.

"Uh... Yes... I totally get that." Tanjiro said and got his answers. Meanwhile you sat down with Nezuko and soon the train started moving.

"GRAAAAAH!! WHOA! WOW!! IT'S SO FAST!!" Inosuke stuck his head outside and you looked as Zenitsu tried to pull him in.

"BE CAREFUL, YOU IDIOT!!" He shouted at Inosuke.

"I'M GONNA GO RUN ALONGSIDE!!! I'LL EAVE IT TO SEE WHO'S FASTER!!" Inosuke said something stupid.

"BETTER NOT! WE HAVE NO IDEA WHEN THE DEMON WILL APPEAR!" Rengoku said something that made you all look at him.

"Huh?" You and Zenistu said.

"NO WAY! A DEMON'S ON THIS TRAIN?!" Zenitsu demanded to know and Rengoku nodded. "IT IS?! GYAAAH! WE'RE NOT TRAVELING TO IT?! IT'S HERE?! GYAAAH! I'M GETTING OFF!!"

"Over 40 people have disappeared on this train!" Rengoku explained. "The corps sent a few swordsmen, but then they all went silent! And that's why I'm here!"

"OHHH! THAT MAKES SENSE!!" Zenitsu started crying. "I'M STILL GETTIN'OFF!!"

"Allow me to inspect... your tickets." The conductor said as you were confused.

"The conductor is going to check out tickets!" Rengoku shouted and you glared at the man.

"That's not what I meant-!" You said as the man's face alerted you.

"Enjoy your trip." The man said and you went wide eyed.

"HEY!" You immediately went to grab your sword but everything changed. It went black...

"Y/n? Are you awake?" You heard a old woman's voice and found yourself in a plain of grass. You saw a woman. "Why are you looking at me like a ghost?"

"That voice...? Grandma..,Kagome?" You asked and she knocked you over the head.

"Why do you say it like a question?! Between you and your mother, you definitely carried more of your grandfather's traits." She said with her arms crossed. You looked around to see yourself with black hair.

"Y/n...? Is something the matter?" Your mother, Moroha, appeared and patted your back. "Did you lose a bet again?"

"Why do you assume it's again?!" You shouted at your mom again, she sighed and out her hand on her hip.

"You know that older siblings-"Tend to mess with younger ones, I know!" You shouted and stomped away. "You always do this!"

"Love you too." Moroha said with a smile and you walked into the woods. "Be safe on the way to Tanjiro's!"

"Okay!" You shouted and continued to walk. When you got to Tanjiro's, he smiled at you.

"Y/n! What's the occasion?" He asked and you sighed.

"Nothing much, just getting away from m...m..." You started to say and then immediately felt your body pulse in and out.

"Y/N! ARE YOU OKAY?!" Tanjiro shouted as Enmu is seen above the train as you sleep with the others. Your body is seen leaning on Nezuko's box with your body flipped upside down.

"Nothing will make me happier than to die as I dream." Enmu commented as the conductor was seen crying.

"I punched their tickets and put them to sleep just like you said. Please, put me to sleep soon too. Please, let me see my dead wife and daughter." He bowed on the ground. "Please.... I Beg you..."

The hand on the ground...nodded. "As you wish. You did well. Sleep now... and meet your family in your dreams."

The man fell to the ground as more kids looked at the hand. "Um... we..."

"I'm a little while, the sleep will deepen: so wait here until then. Malevolence and signs of demons will sometimes awaken demon slayers with good instincts. When you close in to tie them up, be careful not to touch them. Be very, very careful with the demon hybrid, any wrong move could lead to your death." The hand explained. "I have to stay in the front car for a little while. Do your best until my preparations are complete. And may you have sweet dreams too."

"All right." The children said.

"It doesn't matter how strong demon slayers are. Human motivation comes for the heart, from the spirit. You just have to destroy their spiritual core. Do that and why become living corpses that are easy to kill." Enmu said and put his arms out. "All human hearts are the same-fragile and weak like glasswork... but... the hybrid... might be a problem..."

"Should we tie up their arms?" A kid asked.

"Yes. And don't forget the warning to be careful." Your hand was tied as a girl looked around as you gripped your chest. "Is he already figuring it out? I have to move quickly!"

She ran and ran but there didn't seem to be a wall. "Where is it? Where is the barrier?"

She felt the ground move and but and stabbed the ground as a rift opened. She landed in a night filled sky. "This place, so quiet, so peaceful and beautiful."

She approached the core when suddenly! "GAH!!! GGAHHH?!"

The you in reality stood up gripping the girls throat as Rengoku did the same to the girl targeting him. Usually... people who have fallen under the sleep demon's spell cannot move. Trapped in a dream, their consciousness and their physical body are completely severed. Enmu was being extremely cautious. There was a possibility that the demon slayers and the hybrid, despite having succumbed to the spell, would sense his malevolence and break the spell. So he first planned to use humans to destroy the demon slayers' spiritual cores, thereby incapacitating them. He meant to kill their bodies. Those who have lost their spiritual cores cannot resist even when their lives are in danger, and this would be prefect for giving Y/n to Muzan...

But Rengoku and Y/n were able to move... in a spell that should've immobilized them. The girls who entered their dreams gave off no evil aura... but Their bodies instinctively sensed that the destruction of their spiritual cores would render them unable to fight. Y/n's barrier was bigger and wider than anyone Enmu has put to sleep, simply because Y/n's senses are trained to the max. It was almost as if his bloodline was screaming for his body to protect him, the girl Y/n was holding in the air swear she saw multiple people replacing Y/n's face. But, Rengoku and Y/n cannot kill humans so they are at a stand still.

"I should be fine." You said after getting up and holding your head. "What was that? My senses should've picked up on-my senses...? Why would I rely on my senses?"

"Tanjiro, I gotta go." You rushed out of the house as Tanjiro looked at you.

"WAIT!! Y/N!!" He shouted as you started running in the forest.

"Wrong, wrong, wrong, wrong!" You saw a house and saw Urokodaki with Nezuko's box. You stopped running and turned around to see that both had disappeared. You smirked with a pissed expression and started running again. "So those bastards tried to you with me! I gotcha, you fucked up!! NEWS FLASH!!! I NEVER SAW THE FACES OF MY GRANDMA, GRANDPA, OR MY MOTHER!!!"

Nezuko is seen rolling out of her box as she looks at you and Rengoku holding two girls in the air. "?!"

She rushed to you and pulled on your robe. "Mmmfh! Mmhjphh!!!"

She saw it was no use and hit her head on Tanjiro to try and wake him. Her forehead started bleeding and she started crying. She lit her flames on fire and soon did the same to you. You soon were surrounded by pink flames. "...! NEZUKO!!"

"Yes?" She asked you as you froze and didn't face her. "Tanjiro told me to come check on you. You know that you give him a rush everytime you visit.you should hang out with me a bit more often, even I can get jealous."

You put your head down as your mother, sister, Tanjiro, and Grandma Kagome all showed up. Kagome stepped forward. "Y/n? Are you... are you leaving...?"

"Leaving? Mother don't be crazy, he wouldn't..." Your mother said and then saw The Tessaiga on your waist. "What are you doing with that? Y/N, ANSWER ME!"

"This was the only true gift I got from grandpa." You said as Kagome sighed.

"He talked you into this, didn't he?! Let's all calm down and talk." Kagome said and you didn't move.

"I hate to admit it... I really wanna stay."

"Y/n?" Tanjiro asked you.

"Tanjiro, You all were supposed to live a happy life together. Maybe my family and your would be neighbors. It would've been great to be apart of that. With everyone... in peace and harmony."

"Y/n, don't tell me you're-"What's my grandfather's name?" You interrupted Nezuko.

"What...?" She asked and you let out tears and screamed with pure sadness and emotion.

"WHAT'S HIS NAME?! SAY HIS NAME!!!" You shouted and cried. Nezuko rubbed her arm and smiled.

"It's Inuyasha, of course."

"Nezuko could be in the sun, I could be with my mom, grandma, my family. How it was supposed to be, if it was like that, I would still be helping Tanjiro sell charcoal and human."

"I didn't even know his name..." You immediately took off running with Tessaiga pulled out. Nezuko tried to run after you with tears in her eyes.

"PLEASE! DON'T LEAVE ME!! PLEASE!! Y/N!!!" You closed your eyes and ran.

"But I'm too far gone, I'm a demon. And I CAN'T GO BACK TO WHAT I'VE LOST!! I'm sorry, I can't stay with any of you, I'm sorry. I hope to get to know you all for real, when I get out of this."

Tanjiro is seen running in the snowy woods as well. "The demon isn't anywhere. But there's a giant smell and what's this? It's like there's some kind of curtain. It smells faintly of demon everywhere. I can't pinpoint the location. I need to hurry! Nezuko is bleeding and the demons are after Y/n! If everyone else is asleep, things are really bad!"

"Are you really leaving?" A black haired Y/n appeared in front of him.

"Y/N! No, his hair is back to black! This isn't him...! I'll find him when I get out!" Tanjiro shouted in his head as Y/n looked at him. He looked at his getup before chuckling.

"I never took you for a green guy, I always thought more something along the lines of your father." He said and smirked like a demon. "Bloody red."

"YOU'RE NOT THE REAL Y/N! Y/N WOULD NEVER SAY THAT!! THE FACT THAT YOU THINK THIS IS HOW HE ACTS IS DISGUSTING!" Tanjiro shouted and pulled out his sword. Y/n pulled out The Tessaiga.

"Oh yeah, then show me, Kamado. Show me just who I am." He dashed for Tanjiro and attacked him. Enmu looked at the train.

"They're having trouble. I wonder what happened. They haven't destroyed anyone's core yet..." He said and sighed. "As long as the hybrid stays and they're buying time."

You are seen running through the snowy woods and ran to a open plain. A well, a single well one the center of the forest. "This is the only place I remember! There's gotta be something here!"

Tanjiro blocked a strike as he was sent flying back. Y/n slammed the Tessaiga on his blade and walked up you the downed boy. "You should give up here, don't waste my time."

Tanjiro got up again and Y/n clicked his teeth in annoyance. "What?! You're gonna waste your time fighting me, just give up!"

"No way..!" Tanjiro said and held his blade. "Y/n wouldn't give up in the face of danger, When someone is in need and is in danger! He rushes to it! I have people waiting for me, so get out of my way!!!"

Y/n was taken back as he gritted his teeth. "Then you and that annoying demon can both die by the blade!!"

Tanjiro quickly dodged the strike and twisted his body to slice the back of Y/n's neck before he quickly dashed in front of the body and lopped off his head. "Y/n, he wouldn't fight like that. He's stronger and braver than me. That was as fake as this dream, hang on Y/n! I'm coming for you and Nezuko!"

You looked around to see flames growing around the well, after a wave of flame, Inuyasha appeared behind you, although you couldn't see him and your back was turned to him. "Y/N, I know you know nothing about me, but trust me. To free yourself from this world, take your blade, and end it."

You turned around and didn't see him behind you. You knew what that meant and took out your sword. You kneeled down at the well and put your head over it. "Damn it, this is scarier than I thought! Damn it, do I even go to the afterlife? I'm part demon, no! Don't hesitate!! DO IT!!"

You put the sword to your neck. "TO SAVE EVERYONE, END IT!!!"

You sliced your throat and immediately woke up. "AHHHHHHHH!!!"

"Huh?" You looked around and felt something in your hand. You saw girl knocked out and a rope that was cut. You dropped the girl on the floor and looked at Tanjiro. "Tanjiro!"

"Y/n! You're alive!" He said and you raised an eyebrow.

"What the hell were you dreaming about!?! Did I die in your dream?!" You wanted to know but you looked at Nezuko. "Nezuko! You're safe!!"

She ran into your arms and you hugged her tightly. "I'll never leave you. I promise."

"..." Nezuko figured your dream had something to do with this and she pet your hair. She put her hands on the back of your head and pet your hair more. You allowed it and held her face with your hands. "?!"

"Hehehe, your warm body. I missed this." You said as Nezuko started blushing and waving her hands all around. "..?"

"Y/n!" Tanjiro got your attention. "The tickets put us to sleep!"

"Then the demons must already be in the train." You quickly grabbed Tessaiga from under your seat and looked at the ropes. "I'm guessing cutting the ropes wouldn't do anything, Nezuko, can you..?"

Nezuko lit Zenitsu's and Inosuke's ropes on fire, you pondered Nezuko's good mood.

"Wonder that's got her hyped up?" Reason 1 You. You looked at Zenistu. "HEY! CRYBABY! BOAR! GET UP!"

"MMF!" Nezuko pouted and you gave her headpats.

"Yes, I know, you did all you could." You said and Tanjiro looked around.

"IT'S NO USE! THEY WON'T WAKE UP!! RENGOKU!" Tanjiro shouted at Rengoku as he moved. You immediately grabbed the blade as the girl swung at you. You immediately gripped the blade and broke it with your claws. You picked her up by the throat. "Y/N!"

"I'm technically not allowed to kill you, but I can't have you attack us." You said and glared at the woman, unleashing some demon aura.

"Y-You-! Because of you... He won't let... us dream!!" She said and you didn't need to hear anymore as the others woke up. You dropped her and kneed her in the stomach, knocking her out.

"WHAT ARE YOU DOING?! IF YOU'RE AWAKE, HELP OUT!!" Another girl shouted at a crying kid. "I DON'T KNOW ABOUT YOUR TUBERCULOSIS OR WHATEVER... BUT IT YOU DON'T DO YOUR JOB... I'LL TELL HIM SO HE DOESN'T LET YOU DREAM!"

"Shut up, if he doesn't want to get his ass kicked than it's understandable. You kids are pissing me off and there's more important things than dealing with your brats." You said and quickly knocked them all out except the crying kid.

"You want to stay in a happy dream, right? I understand. I wanted to stay in my dream too." Tanjiro said and you gently put the kids down. Nezuko and you looked at the boy. "Are you all right?"

He smiled. "Thank you. And be careful."

"We're demon slayers, we have to be." You said and ran off with Tanjiro. "NEZUKO! We're moving out!"

You and Tanjiro immediately got to the outside and covered your nose. "Ugh-! The demon smell is crazy strong! The front of the train! Got it!"

"Then let's go!" Tanjiro said and you leaped to the top and Tanjiro flipped his body to the top. "Nezuko! Stay there! It's too dangerous! Go wake everyone up!!"

You and Tanjiro took off running and when you took the Tessaiga out again, Tanjiro immediately took out his sword. Enmu looked at the two. "Oh, you're awake? Good morning. You should have stayed asleep. I was showing you both such a good dream. Demon, I showed you the family you never even got to know. And boy, you should thanks me-I could've shown your family being slaughtered. Next time, shall I show your father coming back to life?"

"Oi!" You took gripped the Tessaiga and flames came out from the 9th form. "YOU MADE A BIG MISTAKE ENTERING MY DREAMS! I'M FUCKING PISSED NOW!!"

"Demon Breathing 11th form-!" "Go to sleep..." The hand said and stopped you and Tanjiro halfway to Enmu. You both suddenly woke up and continued to charge at him. "...?...Sleep."

Your body stopped and soon, if not right away, you woke up and charged at him. "Sleep."

"Sleep." Tanjiro woke up again and you hopped onto the next train cart with him and started to raise your sword.

"Demon Breathing 6th form!"

"Sleep!!" The hand shouted again and you both fell asleep and woke up. "Why isn't it working? No, it's working..."

You and Tanjiro are seen slicing your heads off in your dreams. "The spell has caught them many times. But the moment I catch them, they notice it and lull themselves in the dream to awaken! It may be happening in a dream...but killing oneself requires considerable courage. These boys are out of their mind."

Enmu then shows the two nightmares. Inside Tanjiro's dream his family criticized him. The same could be said for Y/n...

"I hate you! I HATE YOU!!" Nezuko is seen shouting at you as you stand over the Kamado's dead bodies. "WHY DO YOU GET TO LIVE?! WHAT MAKES YOU THINK YOU HAVE ANY RIGHT TO LOVE ME?! YOU COULDN'T SAVE MY FAMILY, WHY SHOULD I CARE FOR YOU!? YOU'RE USELESS AND MEAN NOTHING TO ME! I WISH I NEVER MET YOU!!!"

You are then seen on the ground as your mother kicked you to the ground as your sister spat on your beaten body. "I can't believe something as despicable as you came out of me. You did nothing for our family name, you're better off in the ground."

"What did you do besides cry and whine? You couldn't save anyone then, you can't save anyone now." Your sister picked you up by the hair and smirked. "You are nothing but a fake, a human? Nothing about a freak like you is human. You don't even deserve to be alive."

"She's right." Tanjiro said with her and took out his sword. "You couldn't save my family, you mean nothing to me."

"KILL HIM NOW AND GET IT OVER WITH!!" Inosuke shouted as Zenitsu stood next to your sister.

"You don't have to look at that disgrace anymore." He said as Giyu and Urokodaki looked at your body.

"You couldn't even use water breathing? You disgust me." They said as the area changed as you are seen bleeding out as your grandmother shoots and arrow into your heart and traps you in a tree.

"I should've killed you the minute you were born. Nothing good comes out a son of a demon." She said as Inuyasha walked at you and pushed the arrow in further.

"How dare you live without a care in the world? You only survived due to your cowardly nature! There's nothing special about you, you follow others and you lead them to their death. In the end, you're a demon, and you kill everyone. You have no right being alive." He said.

In reality, the nightmares only enraged the two. Y/n didn't realize it, but his blood boiled and he used all of his power to 100%. Even though he was part demon, bringing it to 100% brought him immediately to the level of a hashira due to all the training Y/n had done. He had awoken the form he'd been containing for so long:Demon.

"PART DEMON, HALF DEMON, OR FULL DEMON, I DON'T GIVE A DAMN!! BUT INSULTING MY FAMILY IS WHEN YOU CROSS THE LINE!!!!!!!! MY FAMILY WOULD NEVER SAY THAT!!! I'M GOING TO FUCKING KILL YOOOOOOOUU!!!!!!!!!!!!!!!"

You immediately dashed for Enmu as Tanjiro woke as well. "MY FAMILY WOULD NEVER SAY THAT!! DO NOT INSULT...."

Tanjiro dashed for him as well as you immediately were half way into the neck before Tanjiro was there. But Tanjiro pushed your sword forward. "MY FAMILY!!!"

You cut off the head of Enmu with your sword and you immediately looked at your body to feel the power surrounding you. "Tanjiro, it's not done yet."

"I truly understand... how the master felt when he ordered me to kill you in addition to a hashira and to capture the mutt..." Enmu's face was connected to the train. "Your very existences... grates on my nerves!"

"You think that's gonna stop me...?You got another thing coming." Your voice was deeper and your sclera was blood red. "Let me take a guess, your main body is somewhere else. If I had to guess with the time you had, I'm going to assume that the train is your body. The only reason you would do this is to make us waste time trying to protect all the passengers while you feast on them and by time...am I right?"

"You really get on my nerves, Mutt." Enmu said and sunk in the train.

"Tanjiro, I'll be back." You said and seemingly disappeared but the train shook.

"Was... Was that Y/n's strength?! That was the strength of a hashira!!" Tanjiro noticed as Nezuko is seen slashing the tendrils and kicking them away from the sleeping passengers. She was quickly grabbed and her bones were cracking when Nezuko saw a purple dragon coming straight at her.

"Full Demon Breathing 8th Form: Demonic Dragon." The dragon hit Nezuko and she closed her eyes. The dragon destroyed the Tendrils and left Nezuko uninjured. You then appeared behind Nezuko looking at the oncoming tendrils. "Hmph. Full Demon Breathing 6th form: Demonic Rampage."

You started slicing all around Nezuko and 2 train cars getting rid of all the tendrils in a matter of seconds, you landed on the ground and your feet slide as you stood back straight. Nezuko looked at you in shock. "MHM?!"

"...I didn't want you to see me like this.." You said and wobbled back a bit.

"I have no clue how long this is lasting, but I can't stop now." You said and looked at the Tessaiga. "I used 7th form to stop the regeneration in this area so I should be able to move on without worrying about you."

"Hmm?" Nezuko was still shocked and hugged you.

"?!" You were taken back and tried to move her off. You then smiled as your fangs showed. "I remembering promising myself to confess to you, it'll have to wait a while. Until I get the guts too, I'll just have to protect you in the meantime."

She blushed immensely but she looked around to see you gone. You rushed forward down the cart to see the flame pillar as you both found Tanjiro. "Tanjiro!"

"Kamado! Higurashi!" Rengoku said as Tanjiro looked at you two.

"Rengoku, Y/n!" He said with shock and happiness.

"To come this far, I had to do some really precise blade work... so I think the demon's need some time to regenerate... but there's no time to spare, so I'll make it quick!!" Rengoku shouted. "This train has eight cars. I'll defend the back five! The yellow boy just woke up and is helping your sister in defending the remaining three! You, Y/n, and Hasibira will keep an eye on those three cars as you search for the demons head."

"Whatever it takes to keep everyone safe." You said and Rengoku seems to understand you a bit more.

"WHATEVER SHAPE IT TAKES, AS LONG AS IT'S A DEMON, IT'S GOT A VITAL POINT SOMEWHERE!! I'LL LOOK FOR IT WHILE I FIGHT! NOW, HOP TO IT!" Rengoku took off and you stood up.

"INOSUKE!" You shouted and it shook the car.

"W-What?!" Inosuke said a little scared. "THAT GUY WITH WIDE, STARING EYES GAVE ME AN ORDER! But he's kinda...sorta... AMAZING!! AND THAT PISSES ME OFF!!"

"MEET US AT THE FRONT!" You shouted as you ran forward with Tanjiro.

"ALREADY WAY AHEAD OF YOU!!" Inosuke charged forward and Tanjiro looked at you.

"Y/N! Are you sure it's there?!" He asked you and you nodded.

"It's actually under the train, but I need to head to the front anyway." You picked him up and dashed so fast that you sliced up the hands coming at Inosuke and put him down.

"WHAT THE-?! HOW'D YOU GET HERE SO FAST?!" He shouted as you got your claws out.

"I'm not quite sure. I have a couple theories, adrenaline, bloodline, but I think it's because I'm using 100 %. But I feel something happening to my body." You said as Tanjiro looked at you.

"What?"

"I'm not quite sure, but for now, let's get this open." You, Inosuke, and Tanjiro sliced the bottom and saw a neckbone. Tanjiro immediately attacked it with 8th form but to blocked it. "Full Demon Breathing 7th form: Adapting to Victory."

The Tessaiga turned black immediately as the hands started attacking everyone and. You quickly cut up the arms attacking you arm they never came back. "INOSUKE, Y/N!! LET'S MATCH UP OUR BREATHING AND ATTACK TOGETHER!! SOMEONE WILL ATTACK THE FLESH AND THE OTHERS WILL SEVER THE BONE!"

"GOT IT!!! GOOD IDEA!! YOU HAVE MY PRAISE!!" Inosuke shouted and you gave a smile.

"Look who's become a team player." You said and saw the demon eyes and went asleep, not a millisecond later you woke up and sliced the eyes attacking you. You kept slicing the eye and closed your own so they couldn't get you. You leaped in the air and slammed your fire on the arms, burning the flesh. You quickly saw the neckbone. "INOSUKE!! GET TANJIRO!! I'M ENDING THIS!!"

"Full Demon Breathing 11th Form!!!" You leapt in the air again and stopped moving the air, it was as if you were almost floating. You twisted your body and pushed off the air and sped towards the neck-bone. The air around you was distorting everyone's hearing and the air shook around you. You slashed straight through the train and the whole train shook and the ground below the train shook. "I didn't even get to use it all."

"AAAAAAAAAAAAHHH!!!!!" Enmu screamed as you covered your ears with the others.

"YOU CUT OFF IT'S HEAD SO ITS TRASHING AROUND!! UH-Oh!" Inosuke shouted as you quickly picked up Inosuke and Tanjiro. "HEY! WHAT ARE YOU DOING-?!"

You threw him out as Tanjiro tried biting your hand to let him go and you threw him out. "NO, Y/N! THIS WHOLE TRAIN'S GONNA FLIP!!"

You quickly turned it the train and used your senses to the max again and breathing constant to dash through the train. Time seemed to be moving slower as you saw Rengoku picking up passengers as well and you did the same, you threw them safety outside and went to find Nezuko, your sister, and Zenitsu. You found them and threw them outside before they noticed what was happening. You saw Rengoku wave to you and you nodded. You both leapt off the train as time went seemingly back to normal as your chest pulsed again.

You walked up to Tanjiro. "Hey."

"!!" Tanjiro immediately grabbed your face and headbutt you.

"GAH-!! DAMN YOU!! THAT FUCKING HURT!!" You shouted at him and he glared at you.

"IT'S YOUR FAULT FOR FREAKING ME OUT!!" Tanjiro made a good point as Rengoku walked over next.

"It looks like you both can do total concentration breathing: constant! I'm impressed!" He said and Tanjiro looked at him.

"Rengoku..." Tanjiro said as you looked at him.

"Is there anything we can do to stop the bleeding?" You asked him, Rengoku nodded and looked Tanjiro.

"Concentrate more, improve the accuracy of your breath. Focus on every inch of your body." Tanjiro was told and he followed instructions as your healing factor kicked in and healed you right away, you weren't even tired, but something was happening to you. "There are blood vessels. Broken blood vessels. Concentrate more. That's it... Homeostasis. Stop the bleeding."

Rengoku put his finger on Tanjiro's head. "Concentrate."

Tanjiro closed it and was gasping for air. You looked impressed. "How did you know that would stop the bleeding?"

"Another step to becoming Hashira! Learn all types of tricks!" He said and smiled at you. "There're lots of things you can do if you can master your breathing. That doesn't mean you can do anything... but you'll be much stronger than you were yesterday. I'll give you some pointers when we get back, Y/n. Do you want a bone as well?"

"I know you didn't mean any harm, but that one hurt me." You said as with a smile and Tanjiro smiled as well. "Tanjiro, everyone is safe. Many injuries, but no deaths. Surprisingly, but now when we head back-...!!!"

"What is it, Y/n?" Rengoku asked as you looked up and he did too as a demon suddenly crashed from above. His eyes said Upper Moon Three. He immediately tried to punch Tanjiro.

"Full Demon Breathing 10th Form; Demonic Pinwheel!" You used your demonic energy and spin vertically in a circular motion, cutting the ground below you and sending it at the demon. You cut his arm in half as he leapt back, you sent the ground at him with a mighty kick but the demon punched it all before healing his arm.

"Nice sword. No wonder why Master wants to you." He said and licked his blood.

"Fast regeneration, and overwhelming demon aura. He's an upper moon, but there's no way I can let him out of my sights now." You thought and your chest pulsed again.

"Now why would someone as powerful as you attack the wounded first?" Rengoku asked as the demon put his hand out.

"I thought he might interrupt the conversation we're about to have." Akaza said as you glared at him.

"What talk? I can tell by your cocky demeanor, you're an idiot. I already hate you." You said as Akaza smirked.

"Of course, like you, I also hate weak humans. When I see weakness, my skin crawls." Akaza said as Rengoku looked at him.

"Don't bind Y/n in with you, we all share different values." He said and Akaza out his hand on his hip.

"Aha... then I have a great idea." He said and raised his hand. "Why don't you become a demon?"

"Hmm... no, thanks." Rengoku said as Akaza looked at both of you.

"I can tell your strength by looking at you. You're a hashira. You've developed... your fighting spirit to the edge of perfection. The mutt might as well be a hashira too with all the strength I'm getting from him." Akaza said as Rengoku lost the smile.

"I am the flame hashira, Kyojuro Rengoku." He said and the demon pointed at him.

"I am Akaza. Let me tell you, Kyojuro, why your power will never truly reach perfection. It's because you're human. Because you age. Because you eventually die." Akaza explained. "Become a demon, Kyojuro. If you do... you can train for hundreds of years and keep getting stronger."

"Growing old and dying... is what gives meaning and beauty to the fleeting span of a human life." Rengoku said. "It's precisely because we age and die... that our lives have value and nobility. Strength is not a word... that means much in regard to flesh. These boys aren't weak, do not insult them. I'll say it again, you and I value different things. I have many reasons for not becoming a demon."

"I see." Akaza said as you stayed quiet.

"Y/n." Rengoku said to you, not breaking eye contact.

"Yes, sir...?" You asked him and he gripped his sword.

"Fight." He commanded and you gripped Tessaiga and nodded.

"Yes, Sir." You said as Azaka got in a stance.

"If you won't become a demon, then I'll have to kill you and take the mutt by force!" Akaza charged at you both and you charged first.

"Full Demon Breathing 5th Form: Adamant Barrage!!" When swung, the Tessaiga fired a barrage of diamond shrapnel that went after Azaka. He put his hands up to block it and when he broke them, he didn't see you or Rengoku. Rengoku clashes with Akaza and a large fire burned into the sky. Akaza jumped in the air.

"THE OTHER HASHIRA I'VE KILLED... DIDN'T HAVE FLAMES. STILL, NONE ACCEPTED MY PROPOSAL. WHY IS THAT? AS SOMEONE WHO ALSO WALKS THE PATH THE WARRIOR, I DO NOT UNDERSTAND IT!! ONE CANNOT SIMPLY DECIDE TO BECOME A DEMON. YOU MUST BE CHOSEN!" Akaza shouted. "BUT YOU, WHO WORKED SO HARD TO BUILD SUCH A MAGNIFICENT TALENT, WOULD SIMPLY LET IT WITHER AWAY! SUCH A WASTE!! IT'S HARD FOR ME TO ACCEPT! I CAN'T STAND IT. DIE FOR ME, JYOJURO. DO IT WHILE YOU'RE YOUNG AND STRONG!!"

Akaza unleashed an air type blood art as you took the chance you were waiting for.

"Demon Breathing 3rd Form: Whirling Death!!" You leapt from the ground and twisted your body into drill spin aimed for Akaza's neck. Because he was taken off guard and the speed you were going, Akaza barely dodged it and sent the same attack at you. You were in the air and flipped your body to see Akaza and Rengoku using fourth form to block the attack. "Full Demon Breathing 4th Form; Backlash Wave!"

As soon as the air type hit you, you immediately used your Demonic energy to engulf the his attack in a twister and reverse the flow back on him, the wave swirled around at Akaza as the wave was too big to dodge so Akaza put his hands out as the twister hit his body and sent him back.

"YOU DAMN-!" Akaza then saw you pushing the wave to Rengoku as he dashed forward. "So his plan was to make it easier for Rengoku to kill now because he knows he can't. Well! Sorry to burst your bubble!"

The wave ended as Rengoku was blocking punched from Akaza with his sword. You used Full Demon Breathing 8th Form; Demon Dragon. Five powerful bursts of demonic energy was released and took  the form of a dragons. All five went after Akaza as he jumped around to try and dodge them, You used 10th form to encase yourself in demonic energy and spins vertically in a circular motion downwards at speeds which Akaza dodged. You smirked. "Damn, your fast, but try this ONE!"

Your body pulsedand you felt yourself loosing control. "No!! Not yet! RENGOKU NEEDS ME!"

Akaza ran to punch you but you raised Tessaiga as it turned black. You dodged all the punches and made her to leave tiny cuts on him when you could. You leaped in his arm a moment he tried to punch you. You landed on the arm and sliced his neck, but he covers it with his hand, so you spam around his body to drag The Tessaiga through his body. Before he healed Rengoku sliced Akaza multiple times before he healed. Akaza went for a punch at him again and you spent to slice his legs. He leaped in the air but Rengoku used his third form to slam his blade at him in a downward arc. Akaza went down as you went for a thrust but Akaza used his blood air to send air attacks at you. You used Demon Breathing 5th Form to stop the attacks. "FOR AN NOVICE, YOUR SWORD TECHNIQUE IS WONDERFUL!! YOU SHOULD ENJOY IT WHILE IT LASTS!!"

"YOU NEVER SHUT UP, DO YOU?!" You pushed his blade back and saw Rengoku use fifth form at him and sent what seemed to be tigers engulfed in flames that charges towards the demon  at blinding speeds. You used the Sixth form to send Akaza towards it with every swing being stronger than the last. You pushed him back and you went to thrust your sword, he sent you back with a punch as you went flying on the ground. You flipped up on the ground and dashed back into the fight. Akaza dashed for you as well as you threw Tessaiga at him which he immediately dodged but then was sliced twice in the back. Akaza looked to see Rengoku holding The Tessaiga but it went back to the Katana form. Rengoku used sixth form inspired by you and span at quick speed in a drill shape. Before Akaza could dodge, you grabbed him and ran with him forward. Akaza and you are hit as you both went flying back but healed quickly. You took out your claws and channeled your demon energy as you ran to Akaza. He sent beams of shockwaves at your you leapt in the air. "Iron Reaver Soul Stealer!!!"

The energy came off your claws and made quick work of the blood art. You wiped some blood off of you while Azaka was distracted with Rengoku. By drenching your claws in your own blood, you charged your blood with demon energy and sling it like a barrage of crescent-shaped blades. The blades went at Akaza and he made the mistake of looking at it. "Blades of Blood!!!"

The blades cut him in the shoulder, side, and legs. It healed, but Akaza looked at you from the corner of your eye. "The hybrid is strong, he's definitely a problem. Strong if not stronger than Kyojuro."

You dashed at Akaza as Rengoku threw Tessaiga again, you slid under Akaza's legs and caught it. You twisted your body and slammed the katana on Akaza's arms. "Nice, nice, nice! Show me more, Y/n!"

"You asked for it!" You used 7th to stop his regeneration as you cut him Azaka didn't feel any regeneration activating from his hand. He was on guard and glared at you as you smiled and used Demon Breathing 2nd Form: Wind Scar. Tessaiga released a powerful energy wave that enveloped Akaza in a single sweep. The burst of energy split into three paths on the ground and destroyed most in its path. Knowing that wouldn't hit him, you and Rengoku appeared behind him and pushed him into it. The attack got him and he was pushed into the ground, creating a crater and shaking the terrain.

"That's enough!!" Azaka shouted and pulled himself up and you immediately dashed for him with Rengoku. Azaka tried to hit you with a reverse, rising axe kick. You dodged it and a scrape of it caused your cheek to bleed. You swung the Tessaiga up diagonally as Azaka stepped back to dodge it, Rengoku span in the air and slashed downwards at him. Azaka dodged it and ducked under it as did you but you span all the way around to gain force for the 6th form. Once in front of him, you started attacking him three times; one strike vertically, one diagonally, and one last devastating horizontally blow to the side which sent him bleeding and flying back. Rengoku quickly span his sword horizontally and knocked Azaka back to you. Azaka kicked with both legs in a flowing motion as he ducked, you quickly used Wind Scar on the ground and split it apart, stopping his attack. The ground rose in the air as you landed on one in the air as Azaka did the same. You both leaped off the ground and charged at each other. "If you stop resisting, all of this could be over! Such talent going to waste!!"

"Don't patronize me." You and Akaza attacked all over the air as you used Adamant Barrage to limit Akaza movements before Rengoku fired his fifth form as the tigers hit Akaza and destroyed the ground in the air. You saw the air type attack from Azaka and immediately used Pinwheel to spin down vertically and block the attacks. You slammed your body on the ground and bowed to dodge another punch from Akaza as Rengoku rolled off your back to slam his katana onto Akaza's neck. Akaza quickly lifted his hand and the blade went through it, you used whirling death in a crouched position and sliced the legs in a motion. Akaza had no choice out to leap back. You and Rengoku stood up straight before Rengoku charged forward again.

Out of the corner of your eye you saw Tanjiro trying to move, you gritted your teeth at him. "DON'T YOU DARE MOVE!! YOU'RE WOUNDS WILL OPEN AND YOU WILL DIE!! STAY WHERE YOU ARE!!!"

"WHERE ARE YOU LOOKING, KYOJURO!?" Akaza shouted as Rengoku used fifth form to stop the attack from Akaza. You fell to the ground and let go off Tessaiga.

"GAAAAAH!!!' RAAAAAAAAHH!!!" You shouted in pain and rage as Nezuko slowly opened her eyes. Akaza looked at you.

"Oh? It seems that his body is breaking down due to him mostly being human, how interesting!" Akaza said and sighed. "And that means I can't stay here for much longer, Kyojuro."

"Y/n! To save you...! I'll..." Rengoku looked at you trying so hard to resist losing control.

"Get AWAY!!" You shouted as your body shook. "NO! DAMN IT!! I CAN FEEL MYSELF LEAVING!!!"

"GRAAAAAA!!!" You ran on all fours towards Akaza at high speeds, but your moves were silent. Your pupils were gone and your eyes were filled with red.

"No matter how desperately you fight, Kyojuro, it all useless. That wonderful cut you made has already healed completely." Akaza failed to hear or notice you. "But what about you? Your left eye is crushed. Your ribs are broken. You're bleeding inside. Those are serious wounds. If you were a demon, you would heal in the blink of an eye. To a demon, those are just scratches. No matter how hard they struggle, humans cannot defeat demons."

"I WILL FULFILL MY DUTY!!" Rengoku shouted and actually saw you approaching. "I WON'T LET YOU TAKE Y/N OR LET ANYONE DIE HERE!!!"

You leaped at Akaza and he finmaly realized you, "WHAT THW-!?"

He accidentally used his full strength on you. "NONONONO!!"

"RAAA-! GAAAA-H———!" You shouted in pain as Akaza's fist was through you.

"Y/NNNNNNNNNN!!!!" Inosuke and Tanjiro shouted out as Nezuko watched in heartbreak as she fell to her knees. Akaza started to freak out and Rengoku gripped his teeth.

"Nononono, you can't die! When the master finds out about this!" Akaza tried to remove his hand but it didn't happen. "Huh?! Why won't it?!"

You gripped his arm and smiled as one of your pupils came back. "Hehehe-try this one, Fist Bitch."

He was confused until Akaza heard Rengoku unleash his ninth form: Rengoku! Akaza quickly pushed your body off his arm and you went flying back, at the last second Akaza uses a art to fight back. When the smoke and dust cleared, Akaza's hand was through  Rengoku's. "THAT HYBRID FOUGHT TO KEEP YOU ALIVE! GIVE IN!! SAY YOU'LL BECOME A DEMON, OTHERWISE YOU'RE FINISHED!!! YOU'RE ONE OF THE CHOSEN STRONG ONES!!"

"HOW DARE YOU HURT THE KINDEST DEMON I KNOW?!" Rengoku plunged his sword into the neck of Akaza. "GRAAAAAAAHHH!!!!"

The sun started to come up as You started to move, and was still in rage mode. You picked up the Tessaiga and dashed for Akaza as your demon remembered the hole in your chest right now. "GRAAAAAAAAAAAAAAAAHHHHHHHHHHHH!!!!!!"

Tanjiro and Inosuke seemed to have the same idea as Akaza tried to get away. Before you could cut off the head, Akaza broke his arms in Rengoku and left before the sunrise. Tanjiro threw his sword at Akaza but you couldn't see him anymore. "WHERE ARE YOU GOING, YOU COWARD?! DON'T RUN AWAY!! THE DEMON SLAYER CORPS ARE FLASH AND BLOOD HUMANS! OUR WOUNDS DON'T CLOSE QUICKLY!! LOST LIMBS DON'T GROW BACK! AND YET YOU'LL ONLY FIGHT IS IN THE DARK OF NIGHT WHEN YOU HAVE THR ADVANTAGE!!  SO WHY ARE YOU RUNNING?! YOU ASSHOLE!! COWARD!! YOU'RE AFRAID TO ADMIT...THAT YOU HAVEN'T WON TODAY! RENGOKU HASN'T LOST! RENGOKU IS STRONGER, MUCH STRONGER THAN YOU! HE DIDN'T LET ANYONW DIE!! HE SAW THE FIGHG THROUGH TO THE END!! HE PROTECTED THE REST OF US! THIS IS YOUR DEFEAT! AND THE VICTORY BELONGS TO RENGOKU!"

"HRAAAAAAAAAAAH!!!" Tanjiro started to shouted as tears went down is face. "AAAAAH!! AHHHH!!!"

"RAAAAAAAAAAAAAAAHHHH!! AWOOOOOOORAAAAAAAAHHH!!" You unleashed attack after attack at the forest where Akaza ran off as Rengoku looked at you.

"Y/n, it's alright. Calm down..." He said but you were out of control. You saw Inosuke and you leapt at him, only to be tackled by Nezuko who grew in size and pinned you down. She got you in a headlock but you immediately headbutt her back and she glared at your demon form, not scared of it at all.

"SWT BWY!!" You were suddenly slammed into the ground by the necklace as you raised your body up again, you almost scratched someone but Nezuko brought you to Rengoku as he and Nezuko gave you a hug.

"It's okay, you did your best... It's not your fault..." Rengoku said and tears went down your face before you went to normal. Nezuko wanted to save you more but needed to rush to her box due to the sun. "Thank you, for fighting alongside me. It was an honor. I believe if you train that form of yours, you'll surpass the hashiras in no time."

"It's not fair..." You cried into his shoulder. "We have the same injury, but I'm the only one who's gonna live..."

"Don't think about it like that. There was nothing more you could have done...Tanjiro, you're hurt pretty bad too, Y'know. That cut in your belly will open up and if you die, I won't have my victory anymore. Come here, let's talk a little here at the end." Tanjiro sat down next to you. "I remember something I saw... in my visions of the past. You both should go... to visit house Rengoku, where I was born. There you'll find the writings of past flame hashira. My father read them often, but I didn't ... so I have no idea what's in them. They may contain records of the Hinokami Kagura you mentioned."

The arm in him was destroyed as you gritted your teeth and looked away in sadness. Tanjiro looked at him. "Rengoku... that's enough. Isn't there anyway to stop your bleeding? Can't you use your breathing."

"No. I'm going to die soon. But I have something to say, so listen. I want you to tell... my little brother Senjuro... to take the path that he thinks is right, to follow his heart. And tell... my father to take care of himself. And Tanjiro... I believe in Y/n and your little sister. I consider them members of the demon slayer corps. When I saw them on the train, they shed their own blood to protect humans. If they risk their lives fighting and protecting people.... She's a member of the corps, no matter what anyone says! Stand tall and be proud. No matter how weak or unworthy you feel... Keep your heart burning, grit your teeth, and move forward. If you curl up in a ball and hide, time will pass you by. It won't stop for you while you wallow in grief. Don't worry over my death. I'm a hashira. It's my job to shield you junior members. Any hashira would do the same, we can't allow... the young buds to be plucked."

"Y/n, Tanjiro, Boarhead boy, Blondie there... you all keep learning and growing." Rengoku smiled one last time. "Someday you guys will become hashira and be the pillars of the demon slayer corps. That's what I believe. I believe in you all."

You cried and took Nezuko's box in silence. Zenitsu and your sister came over. "When the train went off the tracks, Rengoku and Y/n used a bunch of techniques... to get everyone out and to minimize the damage to the train cars."

"I know he did." Tanjiro said as Zenitsu was asking too many questions.

"I can't believe... he's dead. Was there really an upper-rank demon?" You glared at him and picked him up.

"YOU HAVE THE AUDACITY TO ASK THAT?! WHERE THE FUCK WERE YOU?!" You shouted at him as your sister gripped your arm.

"Y/N! Stopped!! He saved me from the tendrils! He helped stop my bleeding." She said and you were sad. "Don't take your anger out on him."

You dropped Zenitsu gently and clenched your fist, tears flew down to your fist. "I'm... im sorry."

"It's okay... I was asking too much..." He said as Tanjiro cried even more.

"This is all so frustrating. Everytime I learn to do something new... I learn just how much more there is I don't know about." He said as everyone started to cry again. "These AWSOME people are fighting with such skill and power and I'm still so far behind them. I feel like I'm falling behind. Can I.... Can I ever become anything like Rengoku?"

"DON'T DWELL ON SUCH WEAK THOUGHTS!" Inosuke shouted at you all. "YOU CAN OR YOU CAN'T! IT DOESN'T DO ANY GOOD TO SIT THERE WONDERING ABOUT MAYBES!! HE SAID HE BELIEVED IN US... SO DON'T WORRY ABOUT ANYTHING OTHER THAN LIVING UP TO THAT!! EVERYTHING THAT DIES RETURNS TO THE EARTH... CRYING WON'T BRING ANY OF THEM BACK!! NO MATTER HOW FRUSTRATED YOU FEEL, DON'T CRY!! EVEN IF YOU THINK YOU'RE WRETCHED AND UNWORTHY... YOU MUST KEEP ON LIVING!"

"But you're crying too." Zenitsu called him out. "The tears are flowing out of your mask."

"I'M NOT CRYING!!" He shouted and head butted Zenitsu, which was quickly treated by your sister, Miki. News of Rengoku's death reached Ubuyashiki and the Hashira. When you arrived back to thr butterfly mansion, you had questions.

"My first question is, where is our family?" You asked Miki and she held her head.

"The basic summary of it is that they are trapped in the future, because they went through the well, but they still can interact with us due to Toga's blood in our  bodies." She said and you didn't know what that meant, but moved on.

"Why did you put this spell on me and keep the seal?" You asked and she held her arm.

"The spell was something in case you went out of control... you were right. I abandoned you because I couldn't handle our parents leaving. So I told Nezuko about you, but I'm surprised she kept it a secret all this time." She said and you sighed and got up. "What? No more questions?"

"No, you need to head to work." You said as she sighed and looked at you.

"Um, you literally destroyed my job before that weird Demon fuzed with it." She said and you gave her a needle. She caught it and looked at it.

"Shinobu gave you a job, I put in a good word, don't mess it up." You disappeared from the room as Miki smiled at you.

"You always did act like the oldest..." She said as you are seen looking at the night sky alone. You held the Tessaiga as Nez was trying to hop on the roof.

"Ah, give me a minute." You said and she hoped on the roof that time and laid down next to you. "You wanted to see me? ....
To check up on me..."

"..." Nezuko nodded as a large silence rang out.

"I learned you knew... that I was a demon." You said to her but she didn't seem surprised. "I'm not mad. I'm actually... kinda glad. Thank you, for being in my life."

"...Mhm!" She hugged you and you headpatted her but she slapped it away. You gave her a hug and she took it. You both looked at the starts and she saw a... "PMHJM!"

"A picture?" You said looking at the stars. "Oh, I see it. Looks like a pan."

"Hmm! Mhm!" She was trying to connect the dots and you chuckled.

"What kinda idiot would make star that have pictures a thing? I'm sure it's just a coincidence." You said but she pointed a bigger frying pan. "That's... I got nothing..."

"I can't help think there's more I could've done. Even with stopping the regeneration, he was too fast for it to take effect. But that's an excuse, isn't it? There's no point in crying, like Inosuke said, Rengoku's back in the earth with his mom. Still smiling through it all...."

"What about that one?" You say with a smile as tears come down your face. Nezuko looked at you in silence before intertwining your fingers and nodded. "So I got that one! This is pretty fun!"

"I should Face the demons head on, moving forward and not letting this send me back. I'll become as strong as you, Rengoku... I promise."

You and Nezuko spent the rest of the night stargazing before you journey got more difficult.
