Hikari is a young man with a slender build. He wears a red robe with golden accents over his black uniform, around the center of which is the sheath for his sword. Hikari wears black leggings and boots along with black gloves. He also has black hair tied in a ponytail. Hikari represents none of Clan Ku's ambition and ferocity. Unlike his brother, he is a kindhearted and honorable prince who believes that the kingdom needs allies, community and peace for all rather than enemies and war.
