Romio Inuzuka  

, 犬塚 露壬雄

Grigio Academy Borading School is where Inuzuka, a high school student from Touwa in Japan's east, attends. His dormitory, House Black Doggy, houses people who are often at odds with those living in House White Cat. Despite their rivalry, Inuzuka and Persia, someone from the other house, share a love that they keep hidden to avoid being seen as traitors by their peers. Although Inuzuka can be shy, he is determined and capable of becoming fierce when angry.
