吉本 結衣

Vocals & Guitar.
Yui is a second-year student of Oubi Academy. She is Souta's unrequited love as well as his greatest rival. She is a tomboy and has always been one step above Souta in everything they did. As a result, Souta is always telling her, "When I overcome you, you'll have to go out with me! I'm the one who loves you!" She usually acts obedient and a little slow, but when she gets mad, she becomes just as unreasonable as she used to be, surprising even Yuko. Her weakness is dirty jokes.
