When Yukimura simply can’t watch anymore, he steps out from his hiding spot to put a stop to Shiho and her cohorts’ abuse of Kei. But if he’s expecting gratitude from Kei, he doesn’t get it, and Kiyotaka probably assumed that would be the result of getting involved. When Venus group’s test concludes early, Kiyotaka deduces that Class C is the favorite to win, and starts making some moves.
Those moves involve arranging so both Kei and Chiho’s gang meet in the bowels of the ship, and this time Chiho brings Rika, the girl she demands Kei apologize to. The girls rough Kei up some more, culminating in Chiho realizing that Kei has been traumatized by bullying, and even gets Rika to start slapping Kei silly. All of this is to get Kei to “rock bottom” so he can recruit her for his purposes.
After Chiho leaves, Kiyotaka approaches Kei, who is an absolute wreck, and twists the knife like the true piece of work he is. He tells her he knows what she truly is, and that she and Hirata were never actually dating, and she assumes he’s blackmailing her for her body or something to that extent.
Of course, we know that’s not Kiyotaka’s style, but it’s still a dark and unsettling scene between the two. Kiyotaka would argue, however, that it is all necessary to send Kei to the absolute brink so she’ll take him seriously as an ally. He shows her video of Shiho’s crimes, and offers to protect her from now on in a way the previous guys couldn’t. Because for all the wounds Kei bears—emotional and physical—he still believes she and not Suzune is the best chance of Class D uniting and rising.
Before the final discussion on the last day of the test, Kiyotaka finds Ichinose dozing on the couch, and the two talk about their mutual desire to graduate in Class A (and how she knows he knows how many points she has, but she’s not going to say anything more about that). When the discussion begins, Hamaguchi proposes that everyone should show the rest of the group their phones to reach a better outcome.
Kiyotaka knows that while Hamaguchi presents this option, Ichinose is behind it, and it fits the gambit he already prepared. One by one, Mars Group is convinced to reveal their phones until the VIP is exposed: Yukimura. We then cut to a flashback of Kiyotaka and Yukimura switching phones. Even so, Ichinose calls Kiyotaka and exposes Kiyotaka and Yukimura’s scheme.
But that’s fine, because Kiyotaka isn’t the VIP either…Kei is, and always was. Not only did he switch phones with her before switching with Yukimura, but he also used his personal points to buy the means to switch out the SIM cards, so if someone called his phone, her phone (in Yukimura’s hands) would ring. It’s a great double-switcheroo trap that Mars Group falls for…except for Ichinose, who figured it out, but didn’t stop it because of her rapport with Kiyotaka.
So Class D is the victor, right? Wrong. Class A loses the most points while Class B breaks even, but in a gut punch of an ending Class C is revealed as the ultimate winner. Ryuuen, of whom I am getting thoroughly tired, was able to learn from a Class D student that Kikyou was a VIP. He once again confronts Suzune to gloat and continue to act like a skeevy prick around her. Kiyotaka shows no emotion, but can tell that as this cruise test ends, it’s not going to be smooth sailing for Class D.
