In the village, there is a small temple near the school. Rumors say that Oni-hime-sama's spirit, fearsome being, sometimes takes away the people who go to the temple.

One day when Shuu and Kana were talking about this urban legend, Kensuke, their friend, decides to the temple to bring them proof that the story is fake. A week goes by and Kensuke is still missing. Shuu decides to go to the temple in search of clues to the whereabouts of his friend. Could it be that Oni-hime-sama really took him away?
