You you're watching Demon Slayer and suddenly you enter that anime, you fall from the sky when the upper moons are meeting, they see you on the floor and muzan looks at you confused

Muzan: How did you get in here!?

Douma: Wow he's interesting~

Akaza, hantengu, nakime, kokushibo, gyutaro, daki, gyoko, kaigaku: Not caring/confused
