He uses polite speech toward elders. He travels with Albedo and they are good friends. He is close with Klee, like a brother and sister; they once got caught bomb-fishing together and were locked in the solitary confinement room by Acting Grand Master Jean. Usually soft and gentle, but when he enters 'Black Flame Dragon' (Darkened) mode during battle, the light leaves his eyes and his attitude flips to being aggressive and powerful—a classic gap moe.

On his back is a pair of dragon wings that glow blood-red inside; he usually keeps them small and tucked close to his waist. Behind his waist is a black dragon tail connected like skeletal joints, ending in a diamond shape. He comforts Guest when they are hurt by Loen and wonders why Loen dislikes Guest so much.
