5

During summer break, Nyamo helps Yukari create a balanced routine of rest, leisure, and swimming. Tomo, Yomi, and Osaka visit Chiyo’s lavish mansion and are further astonished when she invites them to her summer house, joined by Sakaki, Yukari, and Nyamo. At the beach, Chiyo, Tomo, and Yomi swim while Osaka shares trivial facts with Sakaki. Later, Tomo and Osaka attempt to spice up the evening with scary stories and inappropriate conversation, but both efforts fail. The group then enjoys fireworks before returning to school. Upon their return, the girls exchange photos from their trip, leading to unexpected and strange reactions when viewing the images together.
