As part of a special test, the school has brought the students to an uninhabited tropical island where they must now live for a week. Their performance on the test can have an enormous impact on the point standings of the four classes.

At the start of the second term, preparations for the sports festival begin. The students are nervous about the fact that performance in the events will affect their written tests, and even more pressure is added by the unique team breakdowns and freedom given to the students to decide who takes part in what event.

As the sports festival comes down to the wire, Horikita must deal with Sudo, as well as Ryuen's threat.

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

Horikita decides to use Paper Shuffle to settle matters with Kushida, and Ayanokoji finds himself caught in the middle.

As the day of the Paper Shuffle draws near, the plans of the various forces in play collide.

Ayanokoji receives a visit from outside the school, and learns more about the conditions of his stay.

Karuizawa, whose cooperative relationship with Ayakoji has ended abruptly, cannot hide her embarrassment at the complete loss of contact with him. As Class D discusses their plans for the future, Ryuen and the other members of Class C appear overbearing.

Ayanokoji makes his final decision on how to deal with Ryuen and the Class C threat.

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

While Class C are discussing Karuizawa and Hirata's break up Yamauchi is approached by Sakayanagi from Class A. Horikita warns that it's a trap, but Yamauchi pays it no heed. Meanwhile, Horikita tells Ayanokoji that rumors are swirling around Ichinose.

Turns out the one spreading the rumors was Hashimoto, who did so at the behest of Sakayanagi. Shortly thereafter, Sakayanagi appears before Class C and she informs them she has evidence regarding the rumors about Ichinose.

Everyone in Class C has passed their year-end exam. While relief flows through the classroom, Chabashira announces a special exam. It will be a class vote to choose three people worthy of praise and three worthy of censure.

With the approaching class vote, a disturbing atmosphere hangs over Class C and fills them with suspicion. Second-year Class A's Asahina informs Ayanokoji that Ichinose has asked for cooperation from student council president Nagumo.

Class C considers various strategies for the special exam, but they all lack a decisive factor. Hirata remains disappointed in the class vote result. Ayanokoji calls out to Hirata, who acts coldly towards Mii-chan who is worried about him.
