Sukuna

Sukuna was an ancient demon who terrorized sorcerers with his four arms and two faces. After remaining undefeated in battle, his essence was split into twenty indestructible cursed artifacts and scattered throughout history. In modern Japan, high school student Yuuji Itadori accidentally released Sukuna after consuming one of these objects. Now reincarnated, Sukuna remains a hedonist who views the suffering of the weak as a natural occurrence, using his immense power to maintain control without regard for consequences.
