Jujutsu Kaisen (from Jujutsu Kaisen Wiki)
The story of Jujutsu Kaisen is set in a world where Cursed Spirits feed on unsuspecting humans and fragments of the legendary and feared demon Ryomen Sukuna have been lost and scattered about. Should any curse consume Sukuna's body parts, the power they gain could destroy the world as we know it. Fortunately, there exists a mysterious school of Jujutsu Sorcerers who exist to protect the precarious existence of the living from the supernatural!

Yuta Okkotsu is a major supporting character in the Jujutsu Kaisen series and the main protagonist of its prequel series, Jujutsu Kaisen 0: Jujutsu High. He was initially a special grade cursed human haunted by his late childhood friend, Rika Orimoto. Satoru Gojo mentored Yuta and enrolled him at Tokyo Jujutsu High.
