Kensaku Hirota is a supporting character in the series. He is a male student in the same class as the protagonist, Masatora Akutsu. Kensaku is generally known for having both good looks and a pleasant personality, yet he is consistently portrayed as having no luck when it comes to romance. His primary character trait is his enthusiastic but ultimately unsuccessful approach to dating; whenever he sees a girl he finds cute, he immediately confesses his feelings, only to be rejected every time. This pattern of constant confession and rejection defines his comedic role within the story. His personality makes him an energetic and outgoing presence, functioning as a class clown or a maker of lively atmospheres among his peers.

Regarding his background and key relationships, Kensaku has a self-proclaimed childhood friend named Yuka Tanabashi. Yuka views another character, Lily, as her rival in love and becomes highly competitive over this, which ties her to Kensaku through their shared connection to the main romantic dynamics of the plot. Information concerning his specific motivations, role in the central conflict, notable character development over the course of the series, and any unique abilities remains unavailable.
