Once a highly regarded member of the Moon Clan, one of the secretive, notorious Masked, Naoki was afflicted by a terrible, incurable curse in the line of duty. Now, for the safety of the clan and all they protect, he spends his days exiled to a remote mountain region, far from the islands he once called home.

His misery is briefly lifted when he chances upon a man being attacked by bandits—a man who proves to be far more than he appears, who needs the unique skills Naoki can provide, and can offer far more than Naoki ever dared hope he could find.
