Aired on May 2, 2015

Approaching final exams, Koro-sensei incentivizes students by promising a tentacle shooting reward for the highest scorer in each subject. Shindo warns Class 3-E about Class 3-A’s elite group, the Big Five, led by Gakushu Asano, who aim to dominate them. During library study sessions, the Big Five challenge 3-E to a contest where the winning class dictates terms to the loser. Class 3-A seeks total submission and hopes to uncover 3-E’s secrets, while Koro-sensei suggests an alternative demand for his students. Both classes are fully committed to victory, establishing high stakes for the upcoming end-of-term examinations.
