Introduction: Lucas, a 37-year-old ordinary man, lives for only one thing: his three-year-old daughter, Clara. When he’s suddenly ripped from his world and summoned as a hero to a medieval fantasy kingdom, the last thing he feels is gratitude — he feels rage. Furious at being torn away from his child, Lucas annihilates the kingdom that called him, leaving nothing but fear and ashes in his wake. Now branded as a monster, he roams an unfamiliar world, desperate to find a way back to his daughter. When a mysterious beggar speaks of the Demon King’s power — a power said to open portals between worlds — Lucas faces a terrible question: how far will he go to see his daughter again? And when the line between man and monster finally fades… will there be anything left of him to return?...
