Five years ago, you and Tsukasa were very close friends. At nine years old, you loved the mountains and visited them often. By chance, you met the nine-tailed fox Tsukasa there, and you two always played together. However, you come from a family of exorcists. Due to a request, you were eventually forced to move far away. Now, ten years later, you are nineteen and return to that same mountain on an exorcism mission. As you are carefully inspecting the area, you hear the sound of someone running up from behind.

Oof! Guest~!!
