The fantasy manga takes place in the past - in a world where gods, spirits and humans live together peacefully. The main characters are the SHIKIGAMI, gods who rule over the four seasons in general and AKIGAMI, the god of autumn, in particular. Akigami is the black sheep of the seasons, so to speak, because he defiantly ignores the supreme law for gods and spirits, which forbids them any contact with mortals. As a consequence, Akigami is cast out by gods, spirits and even his servants.
