Episode 12

"Genius Lives Only One Story Above Madness." (天才とは、狂気よりも1階層分だけ上に住んでいる者のことである.) is the twelfth and the final episode of You-Zitsu anime series.

Summary
Ibuki notifies Katsuragi through a ham radio that she has secured Suzune's leader card as class A and class C were revealed to be working together. With Suzune's illness getting worse, Ayanokōji has her withdraw from the test. But Suzune refuses that and says that losing the card was her fault and it was because she didn't have any friends. Then Suzune faints due to tiredness and Ayanokōji carries her to the teachers camp where Suzune drops out. On the final day, the students clean up their campground and the classes guess the leaders with class B opting not to make any guesses.

At the assembly, Ryūen reveals that he secretly forged a pact with Katsuragi to transfer 200 test points worth of materials to Class-A and will get either the leader card or a photo of it. Class C quickly spent the remaining 100 points and everybody except for Ryuen, Ibuki, and Kaneda, who was assigned to spy on class B, withdrew from the test. Class C would then guess the leaders: Totsuka for class A, Chihiro Shiranami for class B, and Suzune for class D.

The results are revealed, and the winner is class D with 225 points, followed by class B with 140 points, class A with 120 points, and class C with 0 points. The students return to the cruise ship where Alice Sakayanagi reveals that things went according to plan in making everybody mistrust Katsuragi to weaken his leverage over the class as her ally Hashimoto secretly outed class A's leader to Ryūen.

Suzune questions Ayanokōji who explains that he intentionally led Ibuki to stealing the card, and then he had Suzune withdraw so that he could make himself the leader ensuring that class A and class C incorrectly guessed her as the leader.

As for guessing the other leaders, he reveals that he only saw the backside of Katsuragi's card and knowing how cautious he was if he sensed he was being watched, Ayanokōji deduced that Totsuka was really class A's leader. He was also aware that Ryūen had not withdrawn leading him to guessing him as class C's leader as he saw him with the same radio Ibuki was holding. Not wanting to jeopardize class D's alliance with class B that Ayanokōji opted not to find class B's leader as he knew Kaneda would do so. Suzune is in awe at his machinations and tries to question him on what drives him to help her but as it turned out Ayanokōji made it appear that she was the one responsible for class D's victory in order to have others put their trust in her. As the class thank Suzune, Kushida approaches Ayanokoji and asks him if he would trust Horikita or her to which Ayanokoji does not reply.

Ryuen reveals that the main motivation for the alliance with class A is so that the students would sign a contract to receive 20,000 points from each student every month until graduation.

Much later, Ayanokōji meets with Sae Chabashira who reveals it was his father who requested he be expelled though the latter said Ayanokōji would leave on his own accord. Chabashira soon asks him on what he plans to do now, to which vaguely answers as she laughs at his response. Suzune confronts him once more as he calmly states she needed allies and noticed she finally changed. After he confirms he did everything to help her, she gets flustered and blushed before begrudgingly thanking him as she stated she will see him as an ally though she warns Ayanokoji not to get too friendly with her as all she wants is to get to class A.

While she goes on, Ayanokōji internally notes that he doesn't acknowledge her, Kushida, and Hirata as his allies but merely pawns in helping him win. As it turns out, Ayanokōji is more than willing to do anything to accomplish that goal even use people for that purpose believing them to be tools. He ends his monologue by stating that all that matters is him winning in the end.
