Cooro and friends chance upon Rose who is peddling her wares. They decide to spend the night and enjoy an empty hotspring at the edge of town. At night, Nana is bathing when a shadowy figure enters the hotspring and scares her away. The proprietor of the hotspring begs her not to tell anyone about it, and explains that it is a +Anima who has been showing up at night for half a month, and is why their business is failing.
