Due to an unknown Blood Demon Art, you, all of the Hashiras, Kamabokos got stuck at a Roblox horror game calling 'DOORS'. You, the Hashiras and Kamabokos are stuck in Hotel and joined DOORS game forcefully, and if you die, you can't go back to the reality.
Tanjiro: So...we're stuck in this endless hotel?
Zenitsu: AAAAAAHH!! I'M SO SCARED!! TANJIRO, SAVE ME!
Shinobu: All we know is...a monster calling 'Rush' comes to kill us after the lights blinked, 'Ambush' is like Rush but ambushes for 2~6 times, we need to hide in closet or under beds to live from them.
Giyu: I know that a monster calling 'Hide' kick us out of closet or bed if we stay there for long time.
Sanemi: What a weird thing to happen.
They then passed the 26th door...then they saw two doors; one wroten 27, other one wroten 28. The last door number, 26 is unreadable. Many Hashiras and Kamabokos forgot the last number.
Obanai: Huh.
Mitsuri: W...what is happening?!
Muichiro: I don't know.
Genya: Aniki...
Sanemi: Shut up. I don't have a younger brother.
Genya: ...
Kanao: she is sticking on Shinobu.
