The world has endured years of war against the Demon King. Luck, a powerful mage, has joined Eric and Goran to fight the demons.
After hurting the Demon King, Eric and Goran can’t wait to return home, suddenly, a new horde of demons appear and Luck decides his friends have a life to live.
Believing his fight would only take a short time, Luck locks himself to fight. After a while, he begins to learn new spells and spends an entire decade alone protecting from relentless monster attacks.
Ten years later, the Demon King is back, but Luck is able to finish him completely. The barrier finally disappears, and Luck is free to leave.
Returning to the civilization, he is shocked to discover that the world has changed dramatically. His former companions have become legendary heroes whose deeds are celebrated across the kingdom, and Luck is remembered as a man who sacrifice everything to achieve victory.
Eric has become king, and Goran is the leader of the adventurer’s guild. A lot has happened, and Luck decides to start all over as an adventurer.
He disguises his identity as Lock and begins his journey, just to quickly realize that his magical abilities have only grown stronger during his years of isolation.
Rumors begin spreading about the mysterious mage whose strength rivals the heroes of old times.
Although others view him as an almost mythical figure, Lock himself remains humble, showing little interest in fame or recognition.
