Inuzuka is a high-schooler that attends Grigio Academy Borading School. He came from Touwa, east of Japan. His dormitory is called House Black Doggy. The people from House Black Doggy are shown to be always at odds with the people from the other house called House White Cat but in reality, Inuzuka is in love with someone from the other house named Persia. They both are in love with each other but they create a facade to avoid being seen as traitors by their comrades.
Inuzuka is a bit shy but he's determined and he can be scary when he's angry.
