At a shrine in Kyoto, where a brother and sister grew up peacefully, Susa, discovers he is no ordinary boy but rather a vessel for a demon spirit! He then learns to use his powers for the day his fate arrives...

"This story combines a supernatural thriller with shoujo love story very well! The setting is a shrine in Kyoto, where Susa and Nanako have grown up together as siblings since they were small children. Susa, however, is no ordinary boy but something else --- a demon spirit given to Nanako's spiritual magician father and student Dakini to raise as a small baby. So far Susa has managed to live a normal life, but Dakini makes him learn to use his powers against the day his fate arrives... And despite Susa's disbelief, it does arrive. . ."
