When his clan is wiped out by a beautiful demon, young Taikobo finds himself in charge of the mysterious Hoshin Project. Its mission: find all immortals living in the human world and seal them away forever. But what is the ultimate goal of the Project? And does Taikobo even know whose side he's really on?!

Taikobo gets more than he bargained for when he takes over the protection of two young princes prophesized to be part of a much larger master plan. As he unearths more of the truth of The Hoshin Project, Taikobo finds that he may never be able to trust anyone again.
