Mahito possesses the appearance of a tall human with long white hair. His hair is always tied up in three or so sections with a thick strand that occupies the space between his eyebrows. He has two very big scars that run across his face and one that extends around his neck, this could suggest that his body was stitched together at some point. Upon his first appearance his left pupil is black but later both of pupils appear to be grey. He never wears shoes choosing to walk around barefoot instead.
Mahito is seen for the first time in Chapter 16: Compassion. He is located in a tropical location likely of his own making, Mahito is sitting under an umbrella on a beach chair reading a book when Getou first arrives.
