Inuzuka attends Grigio Academy Boarding School, where he's a high school student from Touwa in eastern Japan. He lives in House Black Doggy, one of two rival dorms on campus—the other being House White Cat. The two houses have a bitter rivalry that defines school life, and Inuzuka plays his part, staying loyal to his housemates' cause.
What nobody knows is that he's actually in love with Persia, a student from House White Cat. The feeling's mutual, but they're forced to keep it secret. Being caught together would brand them both as traitors to their respective houses, so they maintain the rivalry act in public while hiding their real feelings.
Personality-wise, Inuzuka comes across as pretty shy most of the time. He's got determination though—once he sets his mind to something, he follows through. Don't get on his bad side: when he gets angry, he can be genuinely frightening.
