Two hundred years ago, the devil Medicis launched a war against humans because of the death of his beloved, the saint Lilith. ．．The leader of mankind, Arthur, the King of Light who personally executed the saint Lilith, raised his holy sword to resist for the survival of the world of light. The war caused by the love affair between Lilith, the Saint of Light, and the Demon Lord Medicis lasted for seven years. ．．

The revenge war of the Demon King Medicis against the Holy King of Light was not successful. In the last battle of the Holy Demon Palace, the Holy King of Light Arthur defeated the Demon King Medicis with a sacrificed attack. In order to prevent all disasters, human beings at that time used the power of the absolute magic circle to seal all the dark people at the end of time and space.
