The first semester has come to a close, and the Ikeda lab is having a party where everyone's bringing what they like to eat and drink. They're having fun, playing games like the "prime number Yamanote line game," when a drunken Himruo finally does a certain something with Yukimura... And even Kanade ends up drunk... On the other hand, the mood quantifier obtained through the previous round-robin kiss experiment has progressed their research tremendously, and in order to gather more data, Yukimura and the others use fairy tales such as "Snow White," "Kaguya-hime," and "The Crane Returns a Favor" as references, but...
I never expected Himuro-senpai to 
be like this when she gets drunk...
...لم أتوقّع أن تكون هيمورو-سينباي هكذا عندما تسكر
Ich hätte nicht erwartet, dass sich Himuro
so gebärdet, wenn sie einen im Tee hat.
No pensé que Himuro
sería así al embriagarse.
No sabía que Himuro
se ponía así al emborracharse.
Je ne l’imaginais pas
réagir à l’alcool comme ça…
Non mi sarei mai aspettata che Himuro-senpai
fosse così da ubriaca...
Não imaginei que a Himuro-senpai
era uma bêbada assim.
Никогда бы не подумала, 
что пьяная Химуро ведёт себя так...
