The male lead character, Kazuki, is a second year student from an elite magic school, Aoi Academy, with serious social problems, and because he has a low spell count of only eight spells, most of the other students, especially the girls, would not notice him until his magical heritage is revealed.

Overall, Kazuki is a good person and helps others by using his magic, even when that means that he runs the risk of turning into ash. His selflessness and kindness eventually wins over the hearts of Rin and Kuriko. He is at times indecisive and uncourageous, but he prevalently shows his honest nature and his sense of doing the right thing.
