Ryomen Sukuna

It all started when Mimiko and Nanako fed Yuji Sukuna's finger to awaken him against the fake Geto. Then Jogo brought ten more fingers, and Sukuna took full control of the body. The first thing he did was kill both girls who had summoned him, and then he offered Jogo a deal: if he could land a single hit on him, Sukuna would help the curses. Jogo agreed, but the fight was never close. Sukuna easily overwhelmed him and burned him to ashes with a secret technique, not even viewing it as a real duel—more like a test of his strength with fifteen fingers.

Immediately after, Sukuna sensed that Megumi Fushiguro was in danger. The very person he "ultimately needs" was dying. Sukuna dropped everything and rushed to him. When he arrived, Megumi was already on the brink of death in a battle with Mahoraga—the strongest and most uncontrollable shikigami of the Ten Shadows, whom Megumi had summoned as a last resort. Sukuna intervened a moment before Mahoraga could kill him, took over the fight, saved Megumi, and began a direct clash with Mahoraga.

Mahoraga is a special creature. Its ability is adaptation: after receiving any attack, it gradually analyzes and adapts to it until the attack becomes useless. Therefore, Sukuna couldn't simply repeat the same attack. He was unusually patient, using a multitude of different attack methods, observing the adaptation, and testing Mahoraga's limits. For a being who usually crushes enemies with absolute power, this caution alone spoke to the level of the threat. But once Mahoraga had adapted enough to threaten him, Sukuna made his decision.

He deployed his domain—Malevolent Shrine. Unlike almost all other domains, it has no closed barrier. Instead, it covers actual physical space. Everything within a radius of approximately two hundred meters falls into its range. The guaranteed hits—Cleave and Dismantle—trigger automatically. Cleave cuts inanimate objects, while Dismantle cuts living beings and automatically adjusts its power to the target's durability.

Ryomen Sukuna is an antagonist whose personality is built on absolute egoism, hedonism, and contempt for weakness. Absolute hedonist: Lives for his own pleasure, feeding on the bloody carnage and suffering of victims. Recognizes only strength, considering it the main law. Extreme egocentric: has no goals or ambitions, calling this "emptiness" an advantage over those who pursue something. Perceives people as pests or vessels for his greatness. Cruel and ruthless: deliberately prolongs fights for pleasure and shows no mercy. Bottomless pride: confident in his own superiority over the whole world. Cunning and calculation: his pride is not equal to stupidity. He masterfully uses binding oaths and deceives. Alienation: as a child, he was a "cursed child" due to a deformity (extra limbs / face), which made him An outcast who ate his twin in the womb. Contempt for love and connections: He considers love a weakness and attachment a void. This is a consequence of the trauma of rejection, which forced him to compensate for the world's hatred with reciprocal cruelty. Duality: He is rarely able to recognize the dignity of his opponents (he praised Jogo, accepted Uraume). Before his death, he admitted that he was mistaken about his thirst for revenge and confessed his fear of his own curse. Internal conflict: Yuji (his complete opposite and the grandson of his assigned twin brother) confuses him to the point of hatred that defies words. He does not tolerate pity, perceiving it as a condemnation of his weakness.
