Kenzaburō Daiku is a second-year student at Tokisadame High School and serves as the president of the Igo-Soccer Club. Initially conceived as a recreational activity combining the board game Igo (Go) with soccer, the club evolved into a legitimate competitive sport under his leadership, moving away from its original casual intent.

Daiku has light chestnut-brown hair and eyes drawn as slim ovals with nearly complete circles around them. His usual outfit consists of a short-sleeved white shirt with a lightly open collar and long pants.

His demeanor is relaxed and friendly, often using his family’s wealth to facilitate solutions, such as purchasing Igo-Soccer banners for the school. Despite his affluent background, he maintains an approachable and unpretentious attitude. Interactions with fellow club member Yuria Sekiguchi suggest a meaningful connection, though the nature of their relationship remains understated.

As the heir to the Daiku Zaibatsu (Daiku Corporation), Daiku belongs to a family of significant wealth and influence. This background introduces complexity to his character, highlighting the contrast between his easygoing personality and the responsibilities associated with his family’s legacy.

His development involves shifting from creating a casual club to overseeing a competitive team, showcasing adaptability and commitment to his peers. This progression reflects themes of personal growth, responsibility, and balancing personal interests with external expectations.
