Aroe is introduced. She has burst her paddling pool and decides to go to a swimming pool instead, but loses her entrance fee. Lightheaded from lack of water, she stumbles home but falls. Chiku-tan comes to her aid by pouring her grandfathers sake onto Aroe's head, which makes Aroe even dizzier. Chiku-tan and Chiku-rin make plans to attend a festival and meet Binchō-tan after she has finished her work for the day. Aroe also attends. Ren-tan has a fortune-telling booth. She tells Aroe's fortune and they meet up with Binchō-tan and the Chiku sisters and share some Ramune Ren-tan has won.

Kunugi-tan watches the festival from afar. As she is not able to attend, her butler goes to the festival and brings her back some Ramune.
