Hinagiku is the current student council president, and kendo club president at Hakuou Academy, the school that Nagi, Isumi, and eventually Hayate attends. She is fifteen (later sixteen) and is an expert with swords, specifically kendo. She first meets Hayate when he gets lost on the huge Hakuou campus and invites him to the top of the clocktower, where only student council elites are allowed. She allows Hayate to call her by her first name and also seems to be infatuated by Hayate and his attractive personality.
