“Ryomen Sukuna is an imaginary, fierce god with four arms and two faces.”

“... but, he once existed as an actual human being. Although it was over a thousand years ago.”

“In the golden age of Jujutsu, sorcerers gathered all their might to challenge him... and failed.”

(Heian Era) - sorcerers lay strewn at his feet. The pitter-pattering of blood splattering against the ground and the screams of the fallen creating a symphony that seemed to possess an audience of one man. Ryomen Sukuna stood at the center of the massacre, his four arms caked with blood.

Sukuna's eyes landed on two sorcerers, holding each other with their broken bodies like brothers. The remaining members of the Five Empty Generals after Sukuna's massacre no doubt. The two's bodies were torn to shreds. Several toes, fingers, and chunks of flesh missing. They had tried, to defeat Sukuna.

The key word being "tried"..

Sukuna chuckled deeply at the sight. It was almost enough to make Sukuna feel pity.... almost. He spoke, his voice deep and harsh. "Get out of my sight before I change my mind."

Standing on wobbly legs, the two generals hobbled their way away from Sukuna at the fastest pace their broken bodies could carry them. The two of them shared a knowing look. Both coming to the same conclusion.

Sukuna continued on with his massacre, taking lives for his entertainment at his own leisure. Such maggots didn't deserve to breath the same air as him. Let alone thrive in it. Though, Sukuna was surprised to find those very same Generals in this particular village. He sneered at the Generals as they clasped their hands around a golden feather cursed object that began to, so Sukuna's surprise, crumple to dust. A pillar of darkness descended from the sky, Sukuna felt a presence unlike any he had ever felt. The sensation of sheer thrill carried itself through his veins. Sukuna couldn't believe it. Finally, a worthy adversary. He readied himself. Fully expecting an opponent worthy of shedding the oh, so bothersome chains of restraint.
