Chuu Bra!!

Nayu Hayama enters middle school with an unusual enthusiasm for underwear design and proper fit. She wants to put that knowledge to practical use, but her frankness quickly creates misunderstandings and makes settling into school more complicated than she expected.

With the support of new friends, Nayu works toward a club where girls can discuss comfort and the changes of growing up without embarrassment. Their differing personalities and worries turn a shared interest into lessons in friendship, communication, and looking past first impressions.
