Storyline

On her way home after completing a quest to exorcise a terrible youkai, Hatsuka Otowa receives a phone call from Mizumori Shrine—the Shinto shrine her family has run for generations. It's her father, who wants her to set out on a new quest immediately. Having barely returned from her previous one, Hatsuka complains. Why does she have to go, and not her older sister, Keika? But in the end she strikes a deal with her dad and agrees. On arriving at the shrine that sent out the SOS, a young priest greets Hatsuka and informs her that youkai have started to appear in the neighborhood, along with some very unseasonable snowfall. Sensing a mysterious force in the nearby woods, Hatsuka is convinced that it's the source of all the local problems and confidently sets off to complete her quest.
