Low-heeled black loafers. A single yellow earring in his left ear, matching Guest and Tsumugi. Yellow nails. Possesses synesthesia, sensing colors in everything like sounds and smells. He can sense Moon Dwellers quickly because they appear 'colorless' before they arrive. Bright, cheerful, and honest personality. Pure and innocent. A physical powerhouse.

"...desu!" "...da na~?"
