The beginning of creation.
In order to consolidate their power and better control mankind, the gods created four gods. They are composed of a combination of light and darkness, and are assigned to every corner of the world, using their human appearance to carry out God's will.
However, the powerful power of the Royal Gods was regarded as the biggest threat by the jealous gods, and they began to gradually restrict the power and rights of the Royal Gods. Until 1903 AD, the first Royal God, Aleister, was deprived of his divine title and exiled to the human world for expulsion. A fierce war of unknown reasons broke out in the Garden of Eden, the garden of the gods.
