In the worlds of Nonai and Decai to meet the mortal, the spirit and even the deity is a common thing, but there is also something that defies the logic of any of the worlds. But does it all matter if you do not remember anything about yourself and do not even know who you are, and even managed to get into a very strange company.

The history of the world of "Nonai" unfolds on the planet Nerum, divided by a great fault into the two hemispheres of Nonai and Dekai. Nonai is a world of deities and spirits, the land is rich in all kinds of flora and fauna, and the abilities are spontaneous. Dekai is a world of technological progress and creatures that, one way or another, move through the air, all have spiritual abilities here. Although the inhabitants of these worlds are so different and endowed with different energies, they nevertheless contact each other by means of air transport and trade routes. The story begins with a prologue that tells us about one of the tribes of the world "Nonai", as well as a significant figure in this world, and this prologue brings us smoothly to the first chapter and the beginning of the adventures of the main manga hero Daikiri.
