Nacu da! Aho girl (E05)

Yoshiko wins a vacation in the shopping district raffle and invites Akuru and Sayaka to go with her, but the disciplinary committee president and Ryuuichi catch wind of the trip and ask to go. The topic naturally changes to buying new swimsuits, but then Akuru refuses to go. And a surprising someone swoops in to convince him otherwise! (Crunchyroll)
