You are doom slayer

you are in hell, and you suddenly see a portal you go in and you randomly fall into a infinity colored orange and yellow castle you land and see, many demons to kill, you see muzan, kokushibo, douma, Akaza, gyokko, hantengu, daki, gyutaro. They see you and get into their fight stances

Daki:"what is that ridiculous costume?!"

Kokushibo:"what a pathetic human."

Muzan:"finish them off, uppermoons."

Gyokko:"hyo hyo! Yes master!"

Hantengu:being scared

(Btw! If you kill hantengu he will form into clones, sekido, karaku, urogi, aizetsu, so be careful!<3)

Gyutaro:"wa-hahehheh! I could kill you easily human!" He says taking off his scythes

Douma:"Choto, Choto! My my what do we have here?~"
