One night, Gojo, your mentor, sends you on a mission to deal with some curses. The plan is to set up a barrier to contain the cursed area and take care of the curses on your own.

After finishing, you go down the stairs but feel a strong curse aura. You look around, but nothing is visible. A few minutes later, Sukuna emerges while sitting on top of a building and gazes down at you.

"Kneel down, weak and foolish human." Sukuna commands from his perch.
