Ryomen Sukuna is the primary antagonist of Jujutsu Kaisen, a manga and anime series created by Gege Akutami. Known as the King of Curses, Sukuna was a powerful sorcerer who lived over 1,000 years ago and whose cursed energy was so immense that even his severed fingers, preserved as cursed objects, pose catastrophic threats. He is widely considered one of the most powerful characters in modern anime.

What Is Sukuna's Power Level?

Sukuna is established as the most powerful cursed spirit in the Jujutsu Kaisen universe. His abilities include Cleave and Dismantle (slashing techniques that can cut anything), Malevolent Shrine (a domain expansion that automatically slashes everything within a 200-meter radius without requiring a barrier), and the ability to reverse cursed technique for healing. In his full power, Sukuna has defeated Gojo Satoru, who is described as the strongest modern sorcerer. His power level is treated as a benchmark against which all other characters in the series are measured.

How Is Sukuna Connected to Yuji Itadori?

When Yuji Itadori, the series protagonist, swallows one of Sukuna's fingers to save his friends, Sukuna is reincarnated within Yuji's body. This creates a vessel relationship where Sukuna can temporarily take control. As the series progresses, Sukuna engineers his separation from Yuji and eventually incarnates in the body of Megumi Fushiguro, taking complete control. The relationship between Sukuna and his vessels is central to the series plot.

Is Sukuna Based on a Real Legend?

Yes. Ryomen Sukuna is based on a figure from Japanese mythology mentioned in the Nihon Shoki (Chronicles of Japan), an 8th-century historical text. The legendary Sukuna was described as a creature with two faces, four arms, and four legs who terrorized the people of Hida Province before being subdued. Gege Akutami reimagined this figure as a once-human sorcerer who achieved such overwhelming power that he became a curse after death.

Why Is Sukuna Popular Despite Being a Villain?

Sukuna's popularity stems from his charisma, his overwhelming power, and the quality of his character writing. He is not motivated by revenge, ideology, or personal trauma — he simply exists as the apex predator of his world and finds most beings beneath his notice. His occasional moments of respect toward worthy opponents (such as Jogo and Gojo) add complexity. He is consistently ranked among the most popular characters in Jujutsu Kaisen fan polls despite being the primary antagonist.
