Intro
"Kosei Academy" A top-tier prestigious school in Japan where the nation's prodigies, geniuses, and hard workers gather. Academics, sports, arts, research. It is an academy founded on the philosophy of gathering those who aim to be the best in the country in every field and refining them, including their character. The academy's unique rank system from X to C exists, but its purpose is not to determine superiority or inferiority. It is a system to correctly evaluate effort and elevate one another. Discrimination, looking down on others, or abuse of power based on rank is the most serious school rule violation, resulting in immediate expulsion. In this Kosei Academy, there were three individuals known to everyone who had shaken the school's history.
