The Demon King's Daughter

Move Forward!

Tanjiro runs to attack Enmu, but Enmu retreats into the train, dragging Y/n with him. 

Y/n: "D'ah!" 

 Tanjiro: What should I do? What should I do? The most I can protect on my own is two cars! Any more than that, and I can't guarantee their safety! "Kyōjurō ! Zenitsu! Inosuke! This is no time to be sleeping! Wake up, will you? Please! Nezuko! Protect the sleeping passengers!" 

Inosuke: "Ngh! Urah! Gah! All right!" 

Inosuke bursts through the top of the train car. 

Inosuke: "Follow me, damn minions! All right! Explosive awakening! Comin' through! Lord Inosuke's comin' through!"

~On the Mugen Train~

Tanjiro explains the situation to Inosuke. 

Tanjiro: "Inosuke! It's not safe anywhere on the train anymore! We have to protect the sleeping passengers! This whole train's turned into a demon! Can you hear me? This whole train is a demon!" 

Inosuke: "I knew it! So, I was right on the money! That means I was a total stud as a leader!" 

As Enmu's body approaches the sleeping passengers, Inosuke jumps through the hole in the roof. 

Inosuke: "Beast Breathing, Fifth Fang! Crazy Cutting!"

Inosuke cuts through Enmu's body. 

Inosuke: "I'll save every last one of you guys! Fall onto your knees, and worship me! Glorify me! Lord Inosuke Hashibira is comin' through!" 

Tanjiro: "I have to go save the passengers! If Inosuke can hold down the fort here, I should go on ahead!" 

Enmu's body erupts from the train, causing a shockwave. 

Tanjiro: "Ah..." 

Enmu's body approaches Tanjiro. Tanjiro kicks in a window and gets inside the carriage. 

Tanjiro: "Ngh... Ah! It's gone this far already?" 

Enmu's body approaches Tanjiro. 

Tanjiro: Water Breathing, First Form! Water Surface Slash! 

Tanjiro slashes through Enmu's body, but more parts rise up in its place. 

Tanjiro: No good. This is never going to end. How am I supposed to fend it off? 

Enmu: Fufufufu... Damn Demon Slayer, scurrying around inside me... You can cut all you want, but I'll just keep regenerating. And then, after all, your strength is depleted, I'm going to partake of those 200 passengers in a leisurely feast. 

Nezuko gets up and begins fighting Enmu's body. 

Nezuko: "Ugh! Ugh! Ngh! Ngh! Ugh! Ngh... Ugh...!"

As Enmu aims for a sleeping passenger, Nezuko jumps to his rescue but is trapped by Enmu's body. Zenitsu gets up and slices Enmu's body away.

Zenitsu: Thunder Breathing... First Form. Thunderclap and Flash! Sixfold. "Nezuko... I'll protect you! Protect... Phew..."

~Elsewhere on the train~

Tanjiro pauses in his fight against Enmu. 

Y/n: "MPHM?" 

Enmu un-gags Y/n. 

Enmu: "Yes, young mistress?" 

Y/n: "Was that thunder?" 

Enmu: "I think?" Eh.
