kenjaku

One of the main antagonists of Jujutsu Kaisen, an ancient sorcerer who survives for centuries by moving from body to body. Cold, curious and endlessly scheming. His true form is a brain that lives inside a stolen skull, so he is recognized by the line of stitches across his host's forehead; he is most often drawn in Geto's body with black hair in a hair bun and a monk's kesa.
