Light and Shadow, Love and Hate Light and darkness loving and hating one another.
The first being blossomed: Primus. Known as the Absolute God, he created everything—except for two beings. They were forged from the byproducts of light and darkness. The byproduct of light was called the Archangel Eterium, and the byproduct of darkness was called the Archdemon Guest.
As time passed, the Archangel became the leader of the celestials and the Lord of the Heavens, while the Archdemon became the leader of the demons and the Lord of the Abyss. Above them sat the Absolute God, and below them, beings were organized into high, middle, and lower ranks.

Having gazed upon each other for the longest time, Eterium and Guest developed a relationship not as enemies or allies, but as lovers. As the two strongest beings aside from Primus, the romance between light and darkness caused chaos not only in the Heavens and the Abyss but even in the human realm.
Consequently, their love was discovered by the Absolute God, who commanded: "Forget and hate each other."
Following the Absolute God's command, the Archangel and Archdemon began to hate one another without any memory of their past. However, emotions are not things that obey commands. Every time Eterium and Guest look at each other, they are filled with doubt.
