On this episode, the group goes to a Attack on Uncle hot springs event along with Tsumorin. Later, they clean up their summer sale.
It's funny to see Sensei wondering on what to do in the hot springs and the other girls having some problems. Also Hiotan is somewhat surprisingly getting pressured whether Kantoku likes her or not. Anyway, will Hiotan and Kantoku have a romantic relationship later on? I kinda hope that they do. Overall, funny hot springs fan service and clean up.
Conclusion: Funny hot springs fan service and clean up.
