Agnes strikes out on her own, but after encountering an old favorite patron, returns to enlist the clan in a hunt for bath crystals. Ritos and Salsa hear of the quest, but misunderstanding, assume that the group is making a trip to an onsen. Leicester, Nick, and the girls enter an abandoned mine to search for bath crystals. They find quite a few, and after breaking for lunch, Agnes and Leicester scout on ahead, discovering a mysterious shrine built around a large crystal. Everyone enjoys bathing in the light of the crystal, but an earthquake sends them scurrying for the exits. A rockfall isolates Agnes and Leicester from the rest of the group, forcing them to find their own way out. The clan reunites outside the mine and celebrate their success by giving Ritos and Salsa some of their extra bath crystals. At home, Shelly pulls a prank on Leicester by sending the girls to the bath before he is finished. Agnes and Leicester end up hiding naked in a corner, hoping not to be discovered by the other girls.
