Arturo knew what it was like to be the butt of jokes, now it's time for others to learn to fear him.

Arturo is a high school student so overweight that the nickname "bowling ball" given to him by his peers fits like a glove. He doesn't score high in school, has never had girlfriends, and has no friends, and perhaps, he never will. He takes refuge in video games, where he spends most of his time, using the joystick as his only form of physical activity.

One day, targeted by Geronimo, the most feared bully at school, Arturo becomes the victim of a cruel prank that leads him towards an untimely death. However, fate has something very different in store for him. At the same moment, in a parallel world, a summoner makes a mistake in a spell, summoning Arturo, reincarnating him in the body of the King of Demons.

Now that Arturo has become the Final Boss, following the patterns of an RPG, he must level up to the maximum to destroy the realm of humans. However, an unexpected surprise slows him down: Geronimo is also summoned, but as the Hero of Light.

Will he be able to maintain control of his realm and not fall back into Geronimo's clutches, or is he destined to repeat the cycle of oppression and victimization?
