The story takes place in modern society. Spiritual people are people who are born with abilities that are different from ordinary people. Some can control fire and wind, and some can transform into beasts and summon spirits. Different factions have different abilities. Spirit people not only exist in modern society, but originated in the long past. Spirit people have been passed down for a long time before the birth of humans. However, unlike human reproduction, the offspring of spirit people often do not actively inherit the abilities of their parents. The inheritance of these abilities requires the help of the secret method of the spirit world. However, with the development of science and technology, people seem to have discovered that they can create spiritual beings with special powers. Although there will be some flaws, they can be much more powerful than ordinary humans. However, these artificial spirits are called semi-spirits or pseudo-spirits in the spirit world.
Under the influence of various factors such as the decrease in the number of inheritors of the secret method, changes in the way of thinking of spirit people and the environment in which they live, the descendants of spirit people have gradually become ordinary people. It seems that spirit people will slowly perish in this era...
