As you were in your dream, something was clicking in your head. 

(Y/N): What's going on here? Why am I- 

Mom: (Y/N), is something wrong? 

(Y/N): N-No Mom. I- Why is Mom here? What's going o- 

Then you noticed that your arm had blood on it. 

(Y/N): What's going on h- AAAAAAAAAGH! 

You were set on fire! 

(Y/N): WHAT'S HAPPENING?! 

You woke up! 

(Y/N): Huh? What th- 

You noticed that Nezuko came out of her box. 

(Y/N): Nezuko, did you- 

She nodded, and you hugged her. 

(Y/N): Thank you Nezuko! 

She blushed and hugged you back. 

(Y/N): Okay, time to help your brother and the others. 

You then noticed ropes tied around them. 

(Y/N): Hmm ... 

You burned them, only to see someone pointing a knife at you. 

(Y/N): This girl ... is the demon controlling her? 

Girl: DON'T INTERFERE! BECAUSE OF YOU HE WON"T LET US DREAM! 

Suddenly others were coming up. 

Girl: HEY! I DON'T KNOW ABOUT YOUR TUBERCULOSIS OR WHATEVER, BUT IF YOU DON'T DO YOUR JOB, I'LL TELL HIM SO HE WON'T LET YOU DREAM! 

(Y/N): WHAT?! THAT BASTARD! He's praying on our weaknesses! My parents! Ruby, Weiss, Blake, and Yang's parental situations, Tanjiro's family, how dare he! I'm sorry everyone, but I have to go and fight! 

You knocked out the passengers! 

(Y/N): Nezuko, you wake the others! 

Nezuko nodded and gave you a thumbs up! 

Then you got up on the train. 

Enmu: Well, look who made it. You should have just stayed asleep. 

(Y/N): You're one of Muzan's Kizuki, right? 

Enmu: Yes. To be honest, your parents seemed like good people. Why didn't you want them back? It doesn't make any sense. I love to see the contortions of a human face. To gave upon someone struggling with their grief and suffering, I just can't take it! When the conductor punched the tickets, the spell was cast! But ... how did he wake up? 

(Y/N): I'll make you pay! Playing with people's minds, is unforgivable! WATER BREATHING: FIRST FORM: CONSTANT FLUX! 

Emu: BLOOD DEMON ART: WHISPERS OF FORCED UNCONSCIOUS HYPNOSIS! 

Enmu's Hand: GO TO SLEEP! 

But you kept charging at him. 

Enmu: WHAT?! What is he- 

You saw images that enraged you, your parents raging at you for not saving them, and for being weak. 

(Y/N): MY MOM AND DAD WOULD NEVER SAY THAT! DO NOT INSULT THEM! 

You decapitated Enmu. 

(Y/N): Well that was easy. That guy that Tanjiro fought seemed stronger. 

Enmu: I underestimated you. Your existence gets on my nerves! 

His head attached to the train! 

(Y/N): WHAT?! 

Enmu: Yes, that expression. I love it. You want me to tell you why I didn't die even though you decapitated me? Well, I'm in high spirits right now! It's simple, that body isn't my main body. You see- 

(Y/N): NO! 

Enmu: YES! I FUSED WITH THE TRAIN! THE ENTIRE BODY IS MY BODY! FLESH AND BONES! HAHAHAHAHAHAHAHA! 

(Y/N): Then that means the passengers are- 

Enmu: MY HOSTAGES! 

He then went back into the train while laughing! 

(Y/N): YOU FUCKER! RUBY! WEISS! BLAKE! YANG! TANJIRO! ZENITSU! INOSUKE! KYOJURO! WAKE UP! PLEASE W- 

Just then Inosuke burst through with Tanjiro and Team RWBY tagging along! 

Inosuke: AAAAAAAAAAAAAAAAAARGH! COME ON MINIONS! LORD INOSUKE IS COMING THROUGH! 

Weiss: WE ARE NOT YOUR MINIONS! 

Tanjiro: (Y/N)! We're okay! Nezuko woke us up! 

Weiss: What's going on? 

(Y/N): The Demon! He's fused with the train! His whole body is a- 

Inosuke: HEH! HAHAHAHAHAHAHAHAHAHAHAHAHA! 

Ruby: Uh ... Inosuke? 

Inosuke: TIME FOR ALL OF YOU TO BOW TO THE MIGHTY INOSUKE! BEAST BREATHING: FIFTH FANG: CRAZY CUTTING! 

Inosuke started to cut the car below them! 

Blake: WHAT ARE YOU DOING?! 

Weiss: YOU'RE GOING TO HURT SOMEONE YOU CRAZY IDIOT! 

Inosuke: INOSUKE IS COMING THROUGH! 

Weiss: Guess we're doing this. WATER BREATHING: SECOND FORM: WATER WHEEL! 

Blake: SHADOW BREATHING: FIRST FORM: SHADOW OF THE FIRST MOON! 

Blake did an upwards slash at the train parts with shadow blades coming out! 

Yang: FISHMAN KARATE: DEMON BRICK FIST! 

Ruby: Man, you guys already know some skills? I need to give this a try! FLOWER BREATHING: SECOND FORM: HONORARY SHADOW PLUM! 

Ruby did circular motion swings at the train as well! 

Meanwhile ... in the train... 

Nezuko was trying to free the passengers, but Enmu's flesh was preventing her. 

Nezuko: Hmm ... 

Zenitsu: THUNDER BREATHING: FIRST FORM: THUNDERCLAP AND FLASH: SIXFOLD! 

Zenitsu cut them all down at fullspeed. 

Zenitsu: Zzzz. Nezuko, I will protect you. 

Nezuko: Uh ... I think I prefer (Y/N) as my future husband. 

Back above... 

You, Tanjiro, and the girls kept cutting apart the train. 

Tanjiro: Are you sure Nezuko is alright? 

(Y/N): Tanjiro, it's fine. She's a demon, she can regenerate. I just hope Kyojuro is okay. 

Speaking of him! 

Rengoku woke up! 

Rengoku: So this is what happened while I was sleeping? SOME HASHIRA I AM! If there were a hole, I'd hide in it! 

(Y/N): Guys! 

Rengoku appeared. 

Rengoku: Young (L/N)! Young Kamado! Rose Girl! Ms. Schnee! Little Kitten! Blonde Girl! 

Yang: HELL YEAH! IT'S RENGOKU! 

Rengoku: To come this far, I had to do some really precise blade-work! 

He made the train shake! 

(Y/N): HA! NICE WORK! 

Rengoku: It has eight cars. I will defend the back five! The Yellow Boy and your sister will defend the other three. The rest of you will search for the demon's head! 

As long as it's a demon, it has to have a vital spot! Now hop to it! 

He then took off as fast as flames! 

Blake: He's amazing. 

(Y/N): Yeah. Now where is the head? 

Weiss: More importantly, where is Inosuke? 

Inosuke: DAMN IT THAT GUY JUST PISSES ME OFF! 

Blake: That's him. 

The stupid pig was running across the roof. 

Tanjiro: INOSUKE! You need to keep an eye on the first three cards as you- 

Inosuke: I KNOW GANPOKITO! I'VE ALREADY FOUND IT! 

Tanjiro: STILL NOT MY NAME! 

(Y/N): Hmm ... it must be- AHA! 

Tanjiro: What? 

(Y/N): THE FRONT OF THE TRAIN! IT'S THE HEAD! 

Soon... 

Inosuke got to the front car! 

Engineer: HEY! WHO ARE YOU?! 

Inosuke: OUT OF THE WAY HANDS! 

A bunch of hands came at him, but he was overwhelmed. 

Inosuke: SHIT! 

??? and ???2: WATER BREATHING: SIXTH FORM: WHIRLPOOL! 

You and Tanjiro cut them down. 

Tanjiro: It's here alright. I can smell it. 

(Y/N): Inosuke! It's here! 

Inosuke: HEY! I'M THE BOSS AND- 

(Y/N): NO! I'm the head of the team, and you listen to me! 

Inosuke: WHO SAID (W/N)?! 

(Y/N): THAT'S NOT MY NAME! 

Inosuke: BEAST BREATHING: SECOND FANG: SLICE N DICE! 

He sliced at the car, and out came the neck bone! 

(Y/N): This is it! 

Tanjiro: WATER BREATHING: EIGTH FORM: WATERFALL BASIN! 

But as he slashed it, the wound closed. 

(Y/N): Damn, this guy regenerates fast! 

More hands started to come! 

Tanjiro: (Y/N)! Inosuke! Let's match our breathing and attack together! 

Inosuke: GOT IT! GOOD IDEA! 

(Y/N): RIGHT! LET'S TEACH THIS BASTARD WHAT HAPPENS WHEN HE SCREWS WITH PEOPLE! 

But then Enmu unleashed another attack! 

Enmu: Blood Demon Art: Eyes of Forced Unconscious Sleep! 

Several eyes appeared. 

(Y/N): NO! NO! 

You then realized what to do! 

(Y/N): ENOUGH! 

You used the Sharingan to stop the eyes! 

(Y/N): NOW INOSUKE! 

Inosuke: RIGHT! BEAST BREATHING: FOURTH FANG: SLICE N DICE! 

He exposed it again! 

(Y/N): TANJIRO! 

Tanjiro: ON IT! HINOKAMI KAGURA: CLEAR BLUE SKY! 

Tanjiro cut the train down, and it decapitated Enmu! 

Enmu: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH! 

The train then came apart! 

(Y/N): WELL DONE TANJIRO!
