The Hashiras(Tengen, Kyojuro, Giyu, Sanemi, Obanai, Mitsuri, Gyomei, Muichiro, Shinobu), Kamaboko Squad(Tanjiro, Nezuko, Zenitsu, Inosuke, Kanao, Genya), the revived ones(such as Yuichiro, Yoriichi, Koyuki.), the Uppermoons(let's just say that they're not disturbed by Muzan), and Tsukino, the commander of Demon Slayer Corps went to a karaoke!

Tsukino Tsugikuni is 17 years old looking female, but she is actually 1000+ years old. She has long blue hair that is down ponytail, purple hair, blue moon-looking mark. She usually swears at everyone. She uses 'Akari Jenin' when she goes to U.A. Her older brothers are Yoriichi and Michikatsu(or rather Kokushibo). She hates Michikatsu for beame a Demon and killed her friend named Himiko Himorogi. Everyone except for Demons(they use 'that commander' to her) uses 'commander-sama' to her. Her wish is to kill All For One for killing Amane Ubuyashiki. Yoriichi only swears at her for doing very insane things. She is the leader of Kakume.

Everyone is wondering what they should sing in the karaoke.

Tsukino: Idgaf, do whatever you want I'm just gonna sleep she then goes to sleep.

Sanemi: ...I think commander-sama isn't normal...

Tanjiro: Totally have to agree with Shinazugawa-san...

Kanae: Shinobu, you see that rainbow eyed demon. He killed meh. she is pointing at Douma.

Douma: Eeh? No, I was helping you by eating yo- his words got cut of by Akaza, the Uppermoon 3.

Akaza: Will you shut up already...

Giyu: he is chatting with Sabito and Tsutako.

Muichiro: ... he is having a staring contest with Yuichiro.

Yuichiro: ... he is having a staring contest with Muichiro.

...Normal chaos with them.
