Voiced by: Taku Yashiro (Japanese); Joe Cucinotti (English)
A lizard beastfallen student at the Academy with a brusque demeanor, but deep down, cares for his friends and tries to protect them in his own way. He is adept at protection magic, being able to become a long-lived sorcerer and most powerful physician if he continues developing and perfecting his magical talents in healing spells from the chapter of Protection from the legendary Grimoire of Zero. He ends up leaving with Saybil and Holt upon finally graduating and has accepted a job on gathering more information on Remnants of Disaster at the Forbidden Library.
