5FrFr! 「怜と理論とブーメラン！」

Rei is worried as he does not have a swimming suit except for the one he had when he was in elementary school. Just as he was worrying, Nagisa came in showing him a bunch of swimming suits and asking him to choose one as he had to take responsibility due to what he said before Rei joined the club. However, Rei cannot make up his mind, thus, Nagisa calls Makoto and Haruka to give advice. In the end, Rei chooses a speedo due to what Makoto had said.

レイは小学生の時以外は水着を持っていないので心配です。渚が心配していたとき、渚は彼に水着をたくさん見せて、レイがクラブに参加する前に彼が言ったことのために責任を負わなければならなかったので、水着を選ぶように頼んだ。しかし、レイは決心できないので、渚は真琴と遥香に電話してアドバイスを求めた。結局、レイは真琴が言っていたのでスピードを選んだ。
