#1 On her way home after completing a quest to exorcise a terrible yokai, 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 yokai 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.
#2 When Keika receives a request to vanquish yokai, her younger sister, Hatsuka, is already out on another quest. Determined to set a good example for Hatsuko, who often fails to show up to training, Keiko visits the village Shinto priest who made the request, who tells her of a giant monkey yokai who has led other yokai on a rampage in and around his village. She confidently accepts the request alone, believing that her powers as a priestess would help overcome them...
#3 One day after the incident over Sesshoseki. The mayor of a nearby village came to Natsu, who was away from the shrine alone, for help. The village head is said to have asked for help from a retired demon because a youkai is rampaging near the village. However, there is only one Natsu at the shrine now. Natsu thinks a little and tells the village mayor that he will do something about it. In this way, Natsu went to exterminate the youkai alone in order to save the nearby village.
