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 Prisoner's ilustrations.
Tsukimitsu is Hinomaru's brother.
- "Hinomaru" means "Round Sun".
