Synopsis[]
The autumn winds approach, but before the talks about the upcoming sports and cultural festival, what comes first is the birthday of Nana, Emina and Touma, where the former's birthday coincidentially is also the same one as the twins. While the sister is cringing in jealousy, the brother is rather happy for such a turn. After an odd birthday, the Cahe club spends their last days of swimming during P.E. and eventually has their body measurements for new uniforms to-be-made by Shizuka. Yet, this body measurement brings upon a few surprises...
