Meiko learns from her teacher about "hansuke tofu," which is made by using the head of an eel that should be thrown away, and touches the essence of the cleanup spirit. And while trying to practice cleanup, Kazue is not pleased with it again. At that time, a parcel and a letter arrive from her parents' house in Tokyo. Meiko's chest is filled with joy and nostalgia, but she can't rely on it, so she hands over the ingredients to Genta. Also, Noriko's homeroom teacher visits Nishikado family's house!
