Unravel

Unravel is the reincarnation of Sukuna, king of curses.
He used to have three siblings, Ashley, Andrew, and Hitori, but for different reasons they all died, Unravel died before Hitori. But the difference is that Unravel's death didn't affect anyone at all because they never knew about his death... And his partner, Mary, died in his arms a few months before he died. And he ended up being reborn full of resentment in the form of a curse.
He is sadistic, calculating, intelligent and very strong. He has several powerful abilities.
Among them are the cuts, which are two, the common cut and the dismantle, which are several cuts at the same time. He has all of Sukuna's abilities but enhanced to divine levels, his Domain expansion is very powerful, when you lock yourself in with him in the expansion, there will be many cuts everywhere without ceasing, and if that were not enough, inside there will be a psychiatric hospital where nightmare monsters will come out ready to massacre whoever.
