Receiving funding from the government to nurture the next generation`s hopefuls, Tokyo Metropolitan Advanced Nurturing High School brings together the brightest youth of Japan onto a single campus. At this seemingly perfect institution, the reserved Kiyotaka Ayanokouji arrives as an incoming member of class 1-D, where he befriends one of his classmates, the antisocial Suzune Horikita. At first, his peers revel in the academy`s leisurely lifestyle, taking advantage of all of its state-of-the-art facilities. Soon enough, however, the facade of Tokyo Metropolitan Advanced Nurturing High School gives way to its true nature—only the top scoring classes can fully utilize the school`s offerings, and Class D is the furthest from such a status. Standing at the bottom of the hierarchy, Class D houses all of the school`s "worst" students. Following this rude awakening, Ayanokouji, Horikita, and the rest of Class D must overcome their differences and clash against other classes in order to climb to the coveted position of Class A by any means necessary.
