Between hunting demons, looking out for his charges and keeping his cousin awake, Yuichi has had little time to work out the mysterious events of seven years ago. But the longer he stays in this town, the more the memories drift back to him, piece by piece...

Yuichi's relationship with Makoto grows more and more confusing each day. It seems the closer the two become, the less they understand about one another. The bond between the two has developed from a once-volatile exchange of insults into a caring and protective union. Their connection has swelled beyond friendship and reached a level which the two of them may not be able to handle.

After the incident at the school ball, Yuichi's relationship with Mai has grown even more uncomfortable and complicated. It cannot be left alone. But in order to understand the reasoning behind Mai's strange devotion to thwarting the mysterious demons lingering about their school, Yuichi must first confront Sayuri.

Yuichi hasn't seen his cousin Nayuki in years. Now that he's back, all knowledge of ever visiting has vanished. He tries to adjust to the vaguely familiar surroundings, but the gaps in his memory haunt him as time grows short. The pieces of the puzzle have appeared - an eerily silent beauty with blazing tresses, the mysterious girl with the winged backpack, and the sword-wielding demon slayer - but it's up to Yuichi to discover how they fit together.
