The second year at Advanced Nurturing High School begins with a new set of challenges for Ayanokouji and his classmates, who face a series of exams and meet their first-year peers. These new students will be paired with second-years for a written test, with the second-years risking expulsion if their team fails. The added complication is that one of the first-years has ties to the White Room, a factor that Ayanokouji must navigate while working to avoid expulsion.
