In the year 2xxx AD, humans are no longer the rulers of the earth. They are replaced by "demons" from aliens. They possess god-like power and their technological development is far beyond what humans know. They are cruel, vicious, bloodthirsty and ruthless, but have beautiful appearances that do not match their hearts.
When the earth is renamed, the home planet of mankind is equivalent to destruction. It is no longer the hometown of mankind, it is just a body, a place ruled by demons.
Status, glory and wealth have become nothing more than illusions, and people with only a beautiful appearance are only worthy of being pets or slaves that the "devil" can play with at will.
Only those with strength can live without being regarded as useless, and she is one of the examples, but even she cannot untie the knot called emotion...
When former lovers, alluring friends, and a group of "demons" intertwine into a chaotic tapestry, can a sharp sword resolve the problem?
