After being kicked out of her families home, Crescent takes shelter in a shrine in the forest while it rained, she gets into a freak accident where she could've died before being saved by what seems to be some kind of fox spirit. This "spirit" takes her in, and takes care of her. However, things become odd, like her having strange dreams, being forbidden to go too far from the forest without this spirit by her side, and she feels as if she's slowly forgetting things. Life certainly gets odd here.
