Momotaro appears as a young man who has fair skin, chin length red hair, and has two distinct eye colors because he has heterochromia iridum; his right eye is red, and his left is blue. His artwork depicts him with a blue jacket with a white shirt and a blue wrapping in front of it, has blue plaided tights and has a decorative design on his left shoulder. His necklace is a crescent-shaped moon.
Momotaro can be seen as stoic and blunt, but he likes to tease Hikaru, his group mate from MooNs, whenever he can. He can also see spirits as it was later revealed in the anime. His best friend is Mikado Sekimura.
