The seaside town of Tamatsue is surrounded by mountains on three sides. Even though it is undergoing modernization via re-development of the coastal area, there is still a feel of a small town in the mountain side. There are two shrines in the town, dedicated to the ‘god of the mountains’ and the ‘god of the sea’, but while the former has a ‘living goddess’ who they are proud of, there is no enshrined deity for the latter. Thus, they invited a new god to take its place. However, the ‘living goddess’ who appeared was rather useless and couldn’t fulfill the roles required of her!
The older brother of the ‘god of the mountains’, Tatsuki, was asked for help by the new goddess, who also became his classmate. While he supported her in her divine training, many other gods descended on the town. It seems that they all had an interest in him...?
