Wait, I'm Not Even the King? Guess I'll Just Build a Harem Anyway!

Are harems difficult?

Klein was just another man of culture—until Truck-kun struck.

But instead of the afterlife, he wakes up in a medieval world... with nothing but ten random treasures drawn from a cosmic gacha.

A talking coin? A cursed crown? A dragon heart? Sure.

But the final pull—the “Legendary” prize—changes everything, the Omni System, a mysterious power that promises him the ability to charm anyone he desires… once he reaches Level 100.

Armed with nothing but his wits, his bizarre loot, and the dream of becoming a king surrounded by peerless beauties, he sets out to conquer the world.

There’s just one small problem: he’s been reborn as a ten-year-old commoner with zero status, no army, and no clue.

From slaying monsters to scheming nobles, from grinding levels to wooing goddesses, this is the story of a man who’ll rise from the mud to the throne—

—to build the greatest army of beauties the world has ever seen.
