What's going on?

You see that your friend cannot control their body anymore, as if they’re possessed. Maybe it is that finger...

You, Toge (Your brother), and your friend witness Sukuna, the owner of the cursed object your friend ate, taking conscience of his surroundings.

Sukuna : ''OH, I'M GONNA MAKE A MASSACRE!!''

Fuck, your friend just awakened the king of curses.
