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

Yukimura injures his leg while the group is training for the upcoming tests. He later devises a plan for how the group should handle the marathon and then the day of the four tests arrives.

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.

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.

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.

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.

As Hirata recovers and the class shows unity, it's finally Ayanokoji vs. Sakayanagi. The final special exam has begun and the first round is basketball. Class C puts up a good fight, but Sakayanagi plans to mentally shake Sudo so he will fall.

The class narrowly lost to Class A in the final exam, and were demoted back to Class D. However, the students showed growth throughout the year. Horikita, in particular, having grown as leader requests to dissolve the alliance with Class B.

It's spring break. Shiina calls Ayanokoji to discuss books. Meanwhile, Class B's Kanzaki appears before Ryuen, who is having a secret meeting with Hashimoto. Although the class was defeated, Kanzaki faces Ryuen without hesitation.
