Taking place within a world of Measurements―superpowers owned from birth, with most being absolute trash.A world involving numerous secret organisations looking to take advantage of those rare and remarkable few possessing exceptional powers.When there exists Forbidden Knowledge better left unknown.When the discovery of said knowledge results in the inevitable; a world-ending catastrophe.‘Ignorance is bliss.’Fighting against the unrelenting persistence of the one who knows all.Before the tragic fate of the world repeats itself once more.―He must be stopped.

Seojin transmigrated into the novel named ‘777: The Crowned Sovereign’ as Seven, a side character.Here, he was the seventh child of the seventh archduke of the seventh kingdom of the seventh continent.On Earth, he was raised by his seventh stepfather and the child of the seventh ex-wife of the seventh mayor. He even had his seventh maid quit the job.He was also the seventh reader of the novel he transmigrated into.[Welcome, Seventh Reader! Your loyalty has been awarded.]With this many sevens, will he curse it as an unlucky number or… praise it seventy seven times?…Note: The author is a complete newbie and this is the seventh draft. Please don't expect this as such a grand story.Thanks. Merci. Danke. Bedankt. Terima kasih. Gracias. Salamat.Congrats! You just learned how to say ‘thanks’ in seven languages! ;P

Waking up in an unfamiliar world with no memories, I had only one advantage—a mind filled with knowledge of fictional tropes, clichés, and common sense learned from countless novels.At first, I thought I was trapped in a romcom nightmare when I started triggering events like “Helping a Girl on a Rainy Day”, “Damsel in Distress”, and “Tripping Into the Heroine’s Arms.” Naturally, I shut those nonsense down before they could escalate. No forced romances. No misunderstandings. No cringe.But something was clearly off.The world wasn’t just a slice-of-life comedy.Beneath the cliché academy setting, there were whispers of awakening powers, hidden dangers, and a brutal magic academy entrance exam.And every challenge I prevented or manipulated was an opportunity to grow stronger.[Title Earned: Background Character.][Achievement Unlocked: Firm Mind.][New Skill Acquired: Background Character's Aura.][New Ability Acquired: Anti-Narrative Influence.]I may be just a background character, but if fate insists on throwing these events at me, I’ll turn them into stepping stones.Let the protagonists play their scripted roles—I have my own path to power.

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. And before him stood four elven women, their expressions filled with reverence and concern.They called him King.Memories not his own flooded his mind—battles, alliances, the weight of a kingdom’s future resting on his shoulders. 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.
