Mahito is one of the primary antagonists of the Jujutsu Kaisen series. He is a cursed spirit allied with Pseudo-Geto. His group’s ultimate goal is the eradication of humanity and ultimately replacing the population with cursed spirits.

As described by jujutsu sorcerers, Mahito is a human-looking cursed spirit with a patchwork face and gray eyes. (In the anime, Mahito possesses heterochromia, as his left eye is dark blue and his right eye is gray.) He has long grayish-blue hair that reaches past his neck and is sectioned off into three large strands with ties at the ends. Along with his face, Mahito has stitches all across his body that give him the appearance that he was sewn together.

Mahito normally sports a black shawl that is separated into three pieces on the left sleeve. He also wears matching pants with and sometimes without white shoes.
