With the island test over, Ayanokoji Kiyotaka and the others are enjoying their summer vacation on a luxury liner. Suddenly, they're interrupted by a new special test. Ayanokoji is called into the same room as Karuizawa Kei and others, where they learn that this test isn't strictly along class lines...

With Day 1 of the "thinking" test over, Ayanokoji is talking to Hirata and the others about a way to break out of the stalemate when he receives a message on his phone from an irritated Horikita. Meanwhile, noticing something strange about Karuizawa's behavior, he seeks information from Horikita, but...

Karuizawa is pushed to her breaking point by the girls of Class C. Ayanokoji watches impassively, but Yukimura flies to her aid, unable to bear it. Noticing Karuizawa's abnormal levels of fear, Ayanokoji seems to get an idea...

Class D prepares to face their next major challenge, a test called "Paper Shuffle" where the price of failure is expulsion.

Ayanokoji's class embarks on their first trial as the ascended Class C, the mixed training camp.

After conversing with her brother Manabu, Horikita offers Yamauchi name as the one who should be expelled. Not only has he made few contributions to the class, but he also worked with Sakayanagi in Class A to expel Ayanokoji.
