Chu-Bra!! Episode 7: "The Summer of Underwear" Summary As summer break arrives, the Underwear Club decides to go on a trip to the beach together, which gives Nayu the perfect excuse to turn swimsuit shopping into an educational mission. While the girls enjoy their time in the sun and test out different swimwear styles, Hiroki (Nayu's stepbrother and lingerie designer) accidentally gets caught in a series of embarrassing misunderstandings that make the group question his presence. However, when a sudden wardrobe crisis strikes on the beach, Hiroki’s professional knowledge helps fix the issue, reaffirming why the girls started the club in the first place. The Verdict The Good: The transition to a summer vacation setting keeps the pacing brisk, and seeing the core four girls bond outside of a strict school environment feels natural and fun. It also offers a decent look at how swimwear fitting works similarly to daily undergarments.
