Citing that France is second only to Japan in cosplay popularity, Chika insists the StuCo welcome their new French exchange students while cosplaying. But when Kaguya and Miyuki put on cat ears, neither of them can resist smiling at the intolerable cuteness of the other.
Regardless, both don’t want the other knowing they find them cute, so they try to tough it out by grotesquely contorting their expressions in a futile effort to hide their mutual delight. To an outside observer like Chika, this looks like they’re glaring at each other with looks that could kill. Loser? Chika…for once!
The StuCo must organize a welcome party for the French, and two of them are needed to do all the necessary shopping, so Chika suggests the two losers of a “banned word” game will do the honors. This is a case of both Kaguya and Miyuki actually wanting to go shopping together, so it behooves them to let Chika win.
That suits Chika just fine, since she wants to win and pulls out all the stops to do so, demonstrating that while the Prez and Veep might look down on her as a second-rate intellect and airhead, she can more than handle herself in a banned-word game. She switches up her manner of speaking by rapping, and has the perfect words she knows Kaguya and Miyuki will readily say if properly stimulated: “love”, and “serious”, respectively.
With Kaguya and Miyuki both losing, their shopping date is set; they just have to agree when and where to meet, which requires one of them text the other for the first time. Kaguya’s maid (and audience surrogate) is somewhat exhausted by her charge’s beating around the bush (as are we all!) so she puts Kaguya in a corner by calling Miyuki then tossing the phone to her.
Miyuki’s extremely stern-sounding father answers, and eventually hands the phone over to his son, who is in the bathtub but doesn’t mind talking since his phone is waterproof. Once they’re talking, the tension fades away, but Kaguya makes the mistake of hanging up when Miyuki was in the middle of saying something else.
Kaguya curses herself while kicking in bed, but the result of her error is that Miyuki ends up being the one to text her first, telling her to stay warm and have a good night. Winner: Kaguya. Unfortunately, it pours so hard Shibuya Station floods, and the shopping trip is cancelled before it can begin. Still, Kaguya’s instinct to go regardless was correct: Miyuki was waiting for her, in the rain, by Hachiko…with his waterproof phone.
Thankfully, Miyuki doesn’t catch cold just in time for the French exchange students’ welcome party, so we get to watch him try to bluff about speaking French when he only skimmed a guidebook. Meanwhile, Kaguya merely pretended not to know French, only to turn around and speak fluently with one of the students. Even Chika, daughter of a diplomat, speaks French and other languages. Just full of surprises!
Little does Miyuki know the headmaster intended the party to be an important test to determine whether he’s truly worthy of leading the school. Betsy, the French StuCo veep and notoriously foul-mouthed master of verbal invective is sicced on Miyuki, and she proceeds to absolutely enrobe him in nasty French insults. Since Miyuki doesn’t speak a lick of French, it all bounces off!
The thing that isolated him ends up convincing the headmaster he does have what it takes, by enduring everything Betsy could through at him with placid “oui, ouis” in response. Even better, when Kaguya overhears Betsy, she comes to Miyuki’s defense, all while showing Betsy is no match for a properly scary Japanese high school girl.
Once the party has ended, Kaguya is ashamed of her nasty word-using, but Miyuki reminds her, he doesn’t speak French, so he didn’t hear any particulars of what she said. All he knows is she didn’t like how Betsy was talking to him, and fought on his behalf. For that, she has his gratitude. And so the episode closes with a win for both Kaguya and Miyuki.
