Merlin is seen as a magicless nobody, yet he is the disciple of the legendary sorceress Lothera and the wanderer feared by the Demon Church. After 18 years of hiding his power, he defeats the Demon Church’s three high priests in the magic tournament. He breaks the queen’s curse, enters a political marriage, and uses judgment authority to avenge his mother. When his mother’s spirit awakens his Hermes bloodline, he unlocks blue-black twin flames and slays the archbishop. Finally, he stands with his mentor to fight the returning Demon King.
