Although the islands were first formed by Izanagi and Izanami, the land was far from peace. Multiple demigods, spiritual deities, and beasts once roamed it. They intuitively hunted or fought against one another to survive. The first god from heaven who descended to Nakatsu Kuni was Susanoo, who was banished due to his reckless and callous behavior towards his elder sister, Amaterasu. His main contribution to dispelling the land's unrest was slaying the giant serpent beast, Yamata no Orochi, and creating his reign in Izumo.
