Hato is a first-year male student who joined during Ogiue's initial membership drive. Though his sexual orientation remains unclear, Hato has a strong affinity for yaoi and boys' love manga and doujinshi, making him a "fudanshi." This passion led him to adopt a female persona, complete with an almost perfect female voice. He attends Genshiken meetings dressed as a girl but goes to classes as a boy. Even after the Genshiken members discover his secret, Hato continues to cross-dress for meetings, prompting the club to arrange for former member Madarame to let Hato change at his apartment.
As a girl, Hato looks and sounds so convincing that male students on campus start trying to uncover more about this "mysterious beauty" who only appears after classes end. Yajima initially found it hard to believe that someone who looked so beautiful as a girl could actually be a guy, but she saw the evidence firsthand when Yoshitake and Hato visited her apartment and the trio got drunk. Hato doesn't think he looks very beautiful when dressed as a girl. Like Sue, Yoshitake, and Yajima, Hato also works as one of Ogiue's paid assistants for her professional manga. Skilled at drawing, he contributes by helping with the background imagery.
