One thousand years ago, a priestess made a promise with a lightning spirit. She would give him her own spiritual energy, and in return the spirit, Kazuchi, would refrain from eating humans. Flash-forward to the present and we learn that Kazuchi has been stuck in a shrine for the last thousand years. Immediately upon breaking free, he looks up the current incarnation of the priestess--- our main character, Yuuto. Though I hesitate to call this a BL-Inuyasha knockoff, the parallels between the two are kind of glaring.
