The gate that had been separating the two different realms was believed to be unsealed by a member of a dark guild, Soraya. Son Lihwan, whose brother was killed by the same mage, desired to take over his brother's mission and uncover the secret behind the gates, needing the help of his enemy, the three-winged Celestial, Soraya. However, what he sees in the future doesn't seem to align in the present. Now he must take the angel under his control to prevent chaos into their once peaceful world.
