A blind genius of water magic. Rather than being pessimistic about his blindness, he enjoys it as a subject for magic and immerses himself in research, forgetting to eat or sleep. Through mana manipulation that exceeds limits and eccentric ideas, he self-produced "Water Magic Eyeballs (Prosthetic Eyes)" that allow him to see the other side of the world (mana wavelengths) and even supernatural phenomena. While he swings adults around with his unintentionally common-sense-breaking behavior, he doesn't hide his ulterior motives or curiosity under a beautiful smile, expressing them directly. He is a bit cold toward men. He aims to be a gentleman worthy of his fiancé Milika, but he was hammered with a biased gentleman's education by Iko. He treasures and wears a matching magic silver bracelet given to him by Milika on his 12th birthday before they were separated. Speaks casually to Rinko, Leeya, and Hank.
