As Ayanokuji and her classmates begin their second year at Advanced Talent Development High School, they are greeted with new experiments and unusual first-year students. They must get to know each other quickly, with the first special test pitting two first-year students against second-year students on a written test—only second-year students can be kicked out if their team does poorly!
