The Miyagi Advanced Academy boasts its high-end facilities, world-class faculty, and its overall capabilities as a school. Kinoshita Haruzaki, a second-year high school student with an astounding 217 IQ (which he keeps as a secret) transfers at Miyagi Academy, hoping that nobody learns about his secret. He just wants to live a peaceful, and normal high school life. Little did he know that Academy's students don't go along well with transferees, in which the "Pureblood and Filthblood" system, wherein you are considered a Filthblood if you haven't been enrolled in the academy since Nursery, exists. Discrimination is so evident in this school that a lot are dropping out because of this. Will Kinoshita find his desired peaceful and normal high school life?
