Kenjiro Hato is the last of the new Genshiken members and the only male to join in Genshiken Nidaime. Kenjiro is a fudanshi (a male fujoshi) and has the same love of yaoi and boy's love doujinshi and manga as the other fujoshi of Genshiken.
Because he assumed being a fudanshi would have caused Kenjiro problems, he adopted a female persona, including a perfect female voice, and dresses as a female when attending Genshiken. He garners a lot of attention in doing so because he's seen as a very attractive girl.
Hato's actual appearance is of a young looking bishounen boy with short dark hair. He is described as having a flawless complexion, which is attributed to his daily use of various moisturizers. He also meticulously plucks his body hair (but uses hair removal lotion at times), giving him smooth and supple skin all over.
As a regular boy, Hato dresses in typical men's casual wear like collar shirts and cargo pants. In his crossdressing form, he will typically wear one of several wigs, the most prominent being a long, thick brunette inspired by his senpai Michiru Kaminaga. He will also dress in very feminine clothing, which garners attention from men as well as jealousy from certain women.
Hato is a mild mannered and generally calm individual. He can get flustered quite easily in embarrassing situations.
When dressed as a male, Hato has a casual way of speaking to people. When Hato crossdresses, he assumes a very feminine identity, including a female voice and a feminine manner of speech. According to the extra manga chapters, the minimum requirement for him to assume his feminine identity is to wear girl's underwear.
Although Hato can change his voice at will, his feminine voice is so strongly intertwined within him that he even speaks in feminine tone in his sleep.
Hato is the last member to join the new generation of Genshiken. Upon arrival, he was seen as such a beautiful, normal looking girl. His looks even intimidated Kuchiki from approaching him. However, as Hato was leaning forward on the table, Kuchiki grasped a strand of hair to feel how soft it was. At this point, it was made aware that Hato was a male wearing a wig. Hato assumed the worst would happen, but as a matter of fact, the members of the club couldn't be happier. Ohno stated Hato put in the most effort to join (and is practically drooling to see him in cosplay), while Kuchiki adored at the idea of a beautiful crossdresser being a part of the club.
