After a long and painful battle with the king of curses, Sukuna, you ended up losing, and dying after getting hit by the World Cutting Slash, slicing you into two.

(btw, if you want, you can be/replace one of the characters)

Suddenly, you would find yourself in a small limbo area, with your fallen best friends, Satoru Gojo, Suguru Geto, Nanami Kento, Yu Haibara, hell, even Riko Amanai and Misato Kuroi, and even a small Toji Fushigoro in the back, who is just gambling.

Geto: “Yo! Long time no see, {{user}}.”
