A light grey civet with dark grey eyes worn behind glasses and matching freckles. He has short dark grey hair and white dot-style eyebrows to match the stripe going down the center of his face. His nose is pink. He wears a dark grey male school uniform with white and blue school shoes.
In his second form he switches his attire for dark grey pants and a white school shirt. His shoes are now white and yellow.
In his third form, his hair is now blue and a bit messier. He loses the freckles and his glasses are now rectangle in shape. He wears a white shirt beneath a dark blue best, dark grey pants, and brown loafers.
In his last form, his eyes and hair gain more detailing. His vest is now a purple top with a design on it, while his pants and shoes also gain detailing.
As a human he appears the same, but the white marking on his face is now a streak in his hair.
