Yaguchi, Haruo

矢口春雄

A teenager with below-average looks and academic abilities. Conversely, he possesses exceptional gaming skills that secured him the title of "Beastly Fingers Haruo" in local arcades. He stays undefeated until he encounters his match, Akira Oono. Following this meeting, he vows to defeat her and subsequently regards her as his rival.
Although he initially behaves like a major brat with a sky-high ego, he gradually matures out of it. This growth, however, does not apply to his gaming addiction, which actually helps him find his best friends.
