The story is set in another world inhabited by gods. This world is positioned above the sky and below the ocean. Four evil gods formerly supported this world by serving as pillars, but they fled, along with all the other minor gods residing there. Consequently, the Kashikan appeared. Their duty is to capture the fleeing gods and restore stability to the country. The protagonist, Ichiyou, is a Kashikan who reluctantly accepted this role to secure his foster father's freedom. His foster father, a tiger, was captured to serve as a replacement for the four gods who had run away. Ichiyou's primary goal is to recapture the evil gods and reclaim the peaceful life he once enjoyed.
