Natsu is sitting alone at Mizumori Shrine. He finds an e-mail requesting the dispatch of exorcists while checking his PC, and after reading the contents, he heads to the village where the request came from. At the village shrine, he hears the details of the request from the priest. The priest tells him that the weather in the village has been getting strange lately, and that youkai have started appearing along with it. Natsu decides to head to the place where the youkai appeared in order to solve the situation.
