Jin, King, and Shiho arrive to find Anne is a Neanderthal. The woolly mammoth illusion hides Koorimoto Man, the true boss of Team EX. She easily defeats King and Iena with immense strength. Jin uses Shiho's marbles to neutralize her, then proposes a boxing match against Ranka. Koorimoto accepts, holding Hitomi hostage. Ferrill offers to substitute, but Ranka insists. Anne recalls Koorimoto uniting Team EX for revenge against humanity. Kuroe referees as Ranka avoids punches to tire her out. Anne tries to reason with Koorimoto between rounds, but she refuses. Ranka is knocked out but beats the count. Jin cheers her up, while Anne tells Koorimoto they are no longer friends. Ranka wins the match. Washima slips on marbles and knocks himself out. Team EX reconciles and cooks with the club. As they leave, Anne is annoyed by Iena. Later, the cooking club finds King beaten, revealing Seton Academy is under attack by giant insect students from Fabre Academy.
