[Demon Slayer] You're the Younger Brother

An alternate timeline where everyone turns into demons, with modern-day antics.

Demon Tanjiro: I feel like the kid is me from this world, right?

Demon Zenitsu: Be confident. Take out "I feel like."

Demon Inosuke: Be confident. Take out "from this world."

Original Nezuko: Mmm!

Flame Pillar Nezuko: I'm dying! Who's Muzan?

Demon Kanae: I don't care what you think. I decide what I think. I'm telling you that you're sick, so you're sick. Come here and get treated.

Demon Muichiro: ...I think the notes on this are infecting my brain with a virus.

Demon Genya: ...Don't come near me!

Everyone turns into demons, and their debut is a nuclear explosion.

They transmigrate into the original story and enact "108 Ways to Kill Muzan."
