Renji was nothing special. No wealth, no fame, no grand ambitions—just a 23-year-old gamer wasting his days in a cluttered apartment, escaping reality through the immersive world of Eternal Realms. In the game, he was powerful, respected, a leader—the elven king, commanding armies and shaping the fate of kingdoms. But outside the screen, he was just another nobody.That all changed the moment his world shattered.What started as a routine gaming session took a terrifying turn when his screen flickered, reality twisted, and an unnatural force yanked him from his chair. When he opened his eyes, he wasn’t in his apartment anymore. He was in a world of towering forests and ancient magic. He was wearing regal robes, a golden crown resting atop his head.

It wasn’t just a game anymore. This was real. And the fate of the elven race now depended on him.But Renji wasn’t a hero. He wasn’t a warrior. He was just a gamer who had no idea how to rule a kingdom, let alone survive in a world teetering on the brink of war.But Just as he was pondering on it a mechanical voice sounded in his mind.
