Atsushi is eighteen and has light gray hair, pale skin, and is of average height with a slim build. He has segmental heterochromia, consisting of purple on the top half of his iris and yellow along the bottom curve of his pupil. He possesses the ability 'Beast Beneath the Moonlight', which basically makes him into a white were-tiger. He's unaware of this, though, and think he's being hunted by said tiger. He's shy, paranoid and constantly apologetic.
