Ryuuen agrees to feed Kikyou with the questions he wrote for Class D, which she’ll use to win the bet and get Suzune and Kiyotaka expelled. In exchange, Kikyou will help make sure Class C wins Paper Shuffle. Ryuuen then takes his gang to go investigate the study group with Kiyotaka and Yukimura, bringing along Shiina Hiyori to try to determine if the Class D Mastermind is among them.
While the experience shakes the group, Haruka likes the vibes they’ve created and decides to formally make them a group, complete with everyone in it being on a first-name basis Airi suddenly inserts herself into the group and asks to join in, presumably to be close to Kiyotaka, and the group agrees.
That night, Kiyotaka calls Kei, but not to invite her to the movie his study group is going to tomorrow. Instead, he has a favor to ask of her. Kei, who wants to become closer to Kiyotaka, has a birthday gift wrapped and ready for him, but has to settle for a LINE sticker, to which he reacts with his usual Ayanokouji stoicism.
The next day when the study group heads meet at karaoke to discuss progress, it becomes clear what Kiyotaka asked Kei to do. She confronts Kikyou for her unrelentingly sweet good girl attitude and accuses her of looking down on her, even tossing a drink on her uniform. Yousuke scolds her and she apologizes, tearfully asking if she can get Kikyou’s uniform washed; Kikyou agrees.
The big day of the Math test that will determine both Suzune and Kiyotaka’s fates arrives, and Maya makes it a point to greet Kiyotaka, only to be shuffled off by a clearly jealous Kei. Yousuke can tell how she’s taken a liking to Kiyotaka, and suggests that having a non-fake boyfriend would probably be best for her.
Before pencils up, Kiyotaka and Suzune revel in the class unity that’s been created through their efforts. Then the test begins, and Kikyou immediately realizes that the test questions she gave Ms. Chabashira are nowhere to be found. Just like that, she’s lost the bet, and she knows it.
Kikyou can’t even pretend to hide her rage when she slams her hands on the desk and then storms out of the classroom. While she’s been a lot more bluster than bite as a villainess, it was still satisfying to see her brought low after she thought she had the Shuffle in the bag.
She meets Ryuuen to voice her anger, but Ryuuen tells her he doesn’t owe her his loyalty, since she couldn’t deliver what she promised him. The bottom line is that before she even made a deal with him, Suzune already had her beat, by going to Chabashira before her and getting her to agree to only accept questions from her, the official class rep.
Kiyotaka explains this to Kei, who then wonders why he had her plant a cheat sheet on Kikyou’s uni. That was only meant to be insurance in case Suzune’s gambit failed. But Kiyotaka has to hand it to Suzune, she achieved this victory all by herself, proving she’s grown as a person and and operator.
Considering the witness, Kikyou has no choice but to abide by the promise she made should she lose to Suzune. Suzune reaches out her hand as a gesture of trust, and is determined to get Kikyou to like her, but Kikyou assures her that will never happen. She also makes clear that while she promised not to try to sabotage her, their deal didn’t say anything about Kiyotaka.
Still, I have to think that the fact that Kikyou and Ryuuen sever their brief alliance can only hurt both parties and help Kiyotaka. He probably knows that too, which is why he presented Ryuuen with the facts on the ground; that Suzune already had Kikyou beat, and got him to agree to a deal to alter Class C’s questions.
Ryuuen doesn’t like one bit that the Mastermind used him the way he so easily uses others, so he plans a bit of revenge in the form of destroying Kei, sending Kiyotaka a photo of her to make it plain. Combined with Kikyou preparing to focus all of her efforts on getting him expelled, Kiyotaka now finds himself in the crosshairs of two adversaries at the same time.
Is that just fine with him? You bet. He welcomes both Ryuuen and Kikyou coming at him with everything they’ve got. It will only make his victories over them that much sweeter. And as huge a prick as Kiyotaka usually is, his commitment to protecting Kei, like his pride over Suzune’s growth, is genuine and admirable. I’m not about to bet against him now.
