三好 一成

Member of the Summer Troupe. "A frivolous and trendy young man who has lots of friends and excellent social skills. He believes that he's friends with everyone he sees, and he talks to everyone and anyone as if he's known them for forever. He's very skilled in graphic design and was responsible for designing the troupes' flyers and promotional website. His relationship with Tsuzuru is the same as a high school senpai-kouhai relationship." [From the A3! Wiki]
