Mugen Train

Since Y/N is not in the butterfly mansion arc, I'm going to skip it.

Y/N: Kyojuro do you really have to scream everytime you eat?

Kyojuro: Yes! I will enjoy every bite for it may be my last!

Y/N: I don't know where you got that idea but okay.

Y/N falls asleep as the train starts to move.

No it's not from the demon art he just fell asleep normally.

Y/N wakes up as he sees the whole train in a mess. Kyojuro is holding a girl's neck, Zenitsu and Inosuke are sleeping. He looks outside the train and sees that Tanjiro is fighting Lower Moon 1, Enmu.

Y/N: Hey, i just woke up whats happening?

Tanjiro: Quickly! When you fall asleep cut off your head!

Y/N: Wait what do you-

Y/N fell asleep from Enmu's demon art.

Y/N: He told me to cut off my head, really? Well i don't think he would just randomly tell a hashira to kill themselves.

Y/N reluctantly cuts off his head and wakes up again.

Y/N: Wow, so it actually worked.

Tanjiro: Yeah but we have bigger problems the demon merged with the train!

Y/N: WAIT WHAT THE F-

Tanjiro: Come here, we need to cut off its neck!

Y/N follows them and sees inosuke there

Y/N: Ok ill start with the top, Thunder Breathing, Second Form, Rice Spirit!

All 3 of them jump down and see the Train Conductor.

Conductor: Why must you get in the way of my dream!

Before he can say another word Y/N knocks him out and throws him off the train.

Tanjiro: Hey why would you do that!

Y/N: If anything bad happens to the train he'll be safe.

Tanjiro: You didn't have to throw him out the train!

Y/N: I did, I just felt like it, Also we have bigger problems to deal with.

Y/N Destroys the lower half with Thunder Swarm revealing the flesh and bone.

Y/N: Alright now go cut it!

Before any of them can launch any attacks they are put to sleep but they all quick wake up.

Enmu does it again but this time Y/N counters it by closing his eyes.

Y/N: Thunder breathing, First form, Thunderclap and Flash!

Y/N Easily cuts through enmu's flesh and cuts the bone but notices the train is about to crash.

Y/N Quickly grabs both Inosuke and Tanjiro and throws them from out the roof.

Y/N!! Tanjiro yells

By spamming thunderclap and flash, Y/N is easily able to get everyone out of the train in time including himself.

Y/N; Yo! You guys okay?

We're fine! Tanjiro yells back.

In the middle of nowhere Upper Moon 3, Akaza shows up.

He instantly rushed Tanjiro who was still hurt from the fall.

Y/n blocks the attack easily and readies an attack
