"Unreality" is a planet slightly larger in surface area than the sun. Unreality features a vast variety of areas that make the most of its expansive land, including forests, plains, oceans, rivers, mountains, deserts, icy lands like Antarctica, demon realms, and underground worlds. Furthermore, the variety of life forms is abundant, ranging from real-world creatures to extinct prehistoric ones, fictional fantasy creatures, and rarely, even creatures from mythology. (Note: With one exception, gods do not exist.) With so many living things, there are many civilizations and nations, ranging from old-fashioned fantasy kingdoms to Japanese-style nations, and even countries that gather the most advanced near-future technology. Unreality is a world where anything goes.

This is a story that warmly depicts the daily life of a girl who is currently human but was once the Creator God of Unreality. The primary setting is "Taube," a country covering approximately 10 million square kilometers that upholds peace and cooperation. In this country, there are no absolute rulers. It is a nation where the fundamental law is for everyone to cooperate with one another. (Even at this size, it is recognized as only medium-sized within Unreality.)
