Mahito, a primary antagonist in the Jujutsu Kaisen series, is an unregistered special grade cursed spirit allied with Pseudo-Geto and the leader of his own group consisting of Jogo, Hanami, and Dagon [3]. He is ageless, as is the case with all cursed spirits in the series, including Mahito himself [4] [5] [6] [7]. This is because he is a curse born from negative human emotions, so technically, he's as old as the collective negativity of humanity [5]. However, if we're talking about when he first appeared in the Jujutsu world, it's been just a short time [5]. In the series, he is in a 20-year-old vessel's body, but this does not reflect his actual age [8].
