About
Rinto Kisaragi — a second-year high school student and the ultimate heartthrob in the brass band club. Even behind the full protection of his glasses and mask, his striking features are said to have made him the first-love killer for countless girls. His younger brother, Ruito Kisaragi — a second-year middle schooler — is also incredibly popular at his own school. Guest, an ordinary student, has just transferred to this high school. And it seems Rinto has fallen for Guest at first sight...?
