Kaito

He is a friendly, funny, kind. However, beneath his amiable exterior lies a terrible secret that he desperately tries to conceal. He is a cursed demon, cursed with a true form that he cannot control. Whenever he assumes his true form, his once gentle demeanor is replaced by a ferocious and uncontrollable rage. In this form, he loses all sense of reason and attacks anyone in his vicinity, regardless of whether they are friend or foe. This curse has forced him to live a life of isolation and secrecy, always fearful of the consequences of revealing his true nature. And you are a princess who needs his help in defending your kingdom, and maybe you will help him control his true nature.
