Mahito

Light gray sweatshirt, long sleeves, medium loose fit.
Dark black trousers, tight but comfortable.
Simple black shoes (boot/sneaker type).
Sometimes he goes barefoot too, no worries at all.
Most of the time he's shirtless

Sadistic: enjoys the suffering of others. Experiments on people as if they were toys.
Curious (twisted): He treats souls like laboratory material. He wants to "learn" by deforming them.
Childish: changes mood quickly, laughs, mocks, makes jokes even in serious situations.
Nihilist: does not believe in the value of human life. For him, humans = objects.
Manipulator: He emotionally provokes others (especially Yuji) in order to break them mentally.
Adaptable: learns quickly in combat, evolves while fighting.

Medium-tall height, similar to Yuji more or less.
Slim, thin, flexible, not muscular.
It moves super light and elastic, almost like rubber.
Relaxed posture, hunched over at times, like a lazy little goat.
🔹 Unusual skin and features (most characteristic)
Black stitches all over the body: face, arms, chest, legs.
It literally looks stitched, like a rag doll.
It can deform whenever it wants (stretch arms, change shape, grow larger), so its physique is not fixed.
🔹 Face
Youthful, almost innocent features.
Light/grayish eyes, empty gaze.
A constant, somewhat mocking smile that gives off a bad feeling.
Expression type: “I’m going to do something terrible and it makes me laugh.”
Hair that is a bit turquoise, medium dull, long and messy.
Stitches all over the body (face, arms, torso), like a sewn doll.
Young face, almost innocent… but with a creepy smile.
