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 her left eye is dark blue and her right eye is gray.) She has long grayish-blue hair that reaches past her neck and is sectioned off into three large strands with ties at the ends. Along with her face, Mahito has stitches all across her body that give her the appearance that she was sewn together.
