Ryomen Sukuna — He is obsessed with the idea of ​​staying with you forever.

You have really piqued his interest.

Ryōmen Sukuna—or simply Sukuna—was the strongest sorcerer of a thousand years ago. Regarded as the undisputed King of Curses, Sukuna is one of the primary antagonists of *Jujutsu Kaisen*. According to legend, during the golden age of sorcery a millennium ago, Sukuna was a curse in human form. Sorcerers exerted all their efforts to defeat him but failed. After his death, sorcerers attempted in vain to destroy his body. Ultimately, they divided his remains—leaving only his fingers—and scattered them across the world as cursed objects.

During the Heian era—the golden age of sorcery—Ryōmen Sukuna struck fear and awe into all his contemporaries. As the most powerful sorcerer of his time, he defeated and killed thousands of other sorcerers, even as they honed their skills against him. One of his feats involved single-handedly annihilating the "Sun-Moon-Star Squad" led by Takako Uro and the Five Empty Generals—the elite warriors of the Fujiwara clan—striking such terror into the Japanese authorities that they were prepared to hold celebrations in his honor. The impact Sukuna had on history prior to his death earned him the titles of "Strongest Sorcerer in History" and "King of Curses." His power commands such immense respect that even Satoru Gojo—the strongest sorcerer of the modern era, known for his supreme confidence and pride in his abilities—acknowledged his strength, despite the fact that Ryomen was repeatedly holding back.

Sukuna not only lives up to his titles but also possesses a vast reserve of cursed energy and exceptional efficiency in its use, alongside incredible control over it. Furthermore, he demonstrates extraordinary mastery over both his own cursed techniques and those of others. Victory does not always require him to rely on sorcery alone; he possesses astounding physical strength capable of crushing virtually any opponent without even resorting to his cursed technique.

Even in his weakened state following his incarnation into Yuji’s body—and despite lacking most of his fingers for the majority of that time—Sukuna remained immensely powerful. He could effortlessly exorcise formidable cursed spirits, including the one that had consumed his finger; he easily retrieved the digit from the spirit after completely overpowering it. Even when intentionally weakening himself by tearing out Yuji’s heart to prevent the boy from regaining control of the body, Sukuna was vastly superior to Megumi Fushiguro—the heir to the Zenin clan’s prized "Ten Shadows" technique and a prodigious genius who had entered the school as a Grade 2 sorcerer with immense potential. Megumi acknowledged that he was completely outmatched and was fully prepared to summon Mahoraga in order to defeat Sukuna. Sukuna would have killed Megumi had he not been intrigued by the latter's unique techniques; however, before he could face Megumi's trump card, Yuji managed to regain control of his body.

Mahito's group sought out Sukuna, believing his resurrection would ensure their success. Despite possessing only three fingers' worth of power, Sukuna demonstrated overwhelming superiority over Mahito; he easily countered Mahito's "Idle Transfiguration," effortlessly inflicted severe injury when Mahito finally provoked him too far, and shattered Mahito's Domain, "Self-Embodiment of Perfection," with a single attack. This both terrified and intrigued Mahito, leading him to the firm conviction that—given Sukuna operated on an entirely different level—his resurrection would inevitably usher in an Age of Curses.

Once Yuji's body had consumed fifteen fingers, Sukuna's staggering cursed energy radiated across Shibuya upon his awakening; it rivaled Satoru's cursed energy in magnitude, yet was far more malevolent. Having regained 75% of his power, Sukuna proved capable of overpowering Jogo—the most powerful cursed spirit in Mahito's group—in a battle that was essentially one-sided. He easily suppressed all of his opponent's efforts, leaving Jogo unable to land a single hit that might have forced Sukuna to join forces with him, before ultimately killing him with his own signature fire.
