Jun is ranked 3rd in school and is Megumi's younger twin brother. The son of a music producer and a talented singer, Jun loves music more than anything else, and is a gifted volinist. Usually quiet and kindhearted, Jun has a split personality which he has concealed from everyone except Megumi and Ryuu. Triggered whenever he is kissed by a girl or receives a lot of affection, he becomes irresistible to nearly all women and is able to charm them effortlessly. His split personality resulted from an hypnotism program that Jun watched as a child and first emerged when he was still in grade six. During a date with a girl, he changed and all the other girls around him became mesmerized by him; this led the girl Jun was dating to hate him and call him disgusting. After he begins dating Sakura, Jun's alternate personality emerges whenever he sees her; however, because Sakura accepts him regardless of his personalities, Jun is able to reciprocate her feelings for him. The only thing that can bring Jun back to his original self is by losing consciousness.
