As the third semester begins in Tokyo Metropolitan Advanced Nurturing High School, it is time for a mixed training camp. Students from all classes and grade levels are participating, making the stakes as high as ever, not to mention the amount of both class and individual points in play. However, that is not all—the students of the groups that fail to meet the required point threshold are in danger of being expelled.

Among the first-year students, the once last-ranked Class D has been promoted to Class C thanks to the efforts of Kiyotaka Ayanokouji and his peers. As everyone in the new Class C gears up for their next challenge, Ayanokouji takes the opportunity to observe the people around him and make new acquaintances. With Class A's representative Arisu Sakayanagi preparing her own plans for him, Ayanokouji must continue using any tools at his disposal if he wants to outwit his most formidable enemy yet and lead Class C to even greater heights.
