Publisher Marketing: After a few months of relative calm, the Sasaki Agency is inundated with requests to solve a series of unnerving cases that appear to have arisen from a single incident. According to eyewitness reports, a man in black has been showing up at a Tokyo hospital and miraculously healing children of incurable diseases and genetic conditions. Yet the recipients of his "treatment" quickly become unrecognizable, exhibiting strange shifts in personality and heralding the arrival of a deity known as Lady Osara. Over the course of her investigation, Rumi realizes that local legends concerning the moon could be the key to solving the mystery. With her paranormal encounters growing increasingly dangerous and her assistant, Aoyama, becoming increasingly distant, can Rumi turn things around before more people are made victims?
