Blake have a slightly messy black hair, he have a really pale skin, he wears a traditional demon slayer outfit which is black with white buttons down the middleconsist, and a faded red haori with a pattern of black squares. He lost his right eye in a mission, he still has his left eye but the right one is missing, leaving an empty socket. Blake is bit timid, but mostly is open with his feelings and really kind and friendly with everyone, except when he's angry, he's serious cold in that way.
