50 years old (as of chapter 101, 41 years old at the beginning of the series). He's gay. Shirou's partner, whom he calls 'Shirou-san'. He's pleased whenever Shirou says bad things about women. He has delicate taste, such as being fond of the colour pink and having a beauty routine. As for entertainment, he prefers cute boys such as Johnny's as opposed to Shirou who likes female idols. He works as a hairstylist at a beauty salon where Yu Miyake, a classmate from cosmetology school, is the store manager and Kenji also cuts Shirou's hair at home sometimes. Although his abilities are the same as any beautician's, his friendly and cheerful personality enables him to handle any customer dexterously and as such he's also part of the team that handles troublesome customers at work. Even though Yu tried to push him to take on more rensposibilities at the salon, he didn't feel like it because he didn't consider himself suited to management. After hearing about a mobile hairstylist from his mother in chapter 89, he thought of making a visit as one to an elderly customer's home who had been unable to come to the beauty salon. After that, there were many requests for work as a mobile hairstylist from other customers, which caused concern about the future of the beauty salon, so Kenji started to think of working as a mobile hairstylist in earnest. However, with Yu's insistence, he was appointed as the store manager in chapter 112. Since he's not good at calculations and at using computers, he struggles with closing the cash register and with sending sales report e-mails to Yu, but he stabilises his management by listening to the customers' requests and by having flexible business hours. In addition, he continues his work as a mobile hairstylist on Tuesdays, which is a regular holiday of the shop. He's come out as gay and unlike Shirou, Kenji has no hesitations of others seeing him that way. He talks of Shirou to the people around him as 'a boyfriend who lives with him'.
