A teenage kid whose looks and academic skills are below average. On the other hand, he's got amazing gaming skills that earned him the title of "Beastly Fingers Haruo" in the local arcades. He remains undefeated until one day he meets his match, Akira Oono. After the encounter he vows to beat her, and later on considers her as his rival.

While initially acting like a major brat with a sky-high ego, he bit by bit grows out of it, the same couldn't be said about his gaming addiction, which actually helps him find his best friends.
