Hinomaru (日丸) is one of the characters that has yet to appear in any series. He is a beetle and Tsukimitsu's brother.
Hinomaru has red eyes and raceless skin. His hair resembles a beetle's mouth. He wears a simple gakuran unbuttoned from the third button upwards. He also has a pair of black shoes.
He seems to be very cheerful and upbeat, contrasting against his brother's serious personality.
Not much is known about him, other than that he is Tsukimitsu´s brother and, most likely, an inhabitant of the Pitch Black World.
Up to this point, he has only been seen in some of Deep-Sea Prisioner´s ilustrations.
Tsukimitsu is Hinomaru's brother.
- "Hinomaru" means "Round Sun".
