A Certain Omni-Duo

Vilgax had already won. Earth burned, its skies torn apart by warships and alien fire, cities reduced to silence under his rule. There were no heroes left standing. The boy who once fought everything the universe threw at him was there to witness it, battered, furious, and too late to change anything. But time doesn't always move in one direction.

A certain time traveler intervenes, pulling him from the ruins of that broken world and dropping him into another version of Earth, one that feels familiar, yet dangerously different.

A city of science rises at its core, where power is not granted by chance, but cultivated through calculation. Here, espers walk the streets, their abilities ranked and refined, their existence governed by cold, precise systems. Among them stand the Level 5s, monsters in human form whose strength alone can tilt the balance of nations. Yet even in this advanced world, danger festers beneath the surface.

Because this Earth is not safe.

Creatures known as EVOs roam beyond control, twisted by unstable nanites that warp biology into living weapons. Science and chaos collide in unpredictable ways, creating threats that neither esper abilities nor technology alone can fully contain.

The Ultimatrix reawakens.

With it, a broken hero rises once more, no longer the boy who failed, but something sharper, colder, and far more dangerous. This time, he does not fight alone. A stubborn lightning princess who shocks first and asks questions later. A loud, reckless kid who can turn his body into weapons without thinking twice.

Around them gather the strongest espers, an ultimate team forged not by chance, but by necessity. Together, they hit back, against EVO outbreaks, against shadowy experiments, and against threats that feel a little too close to the past he's trying to outrun. Because Vilgax isn't just a memory. And if there's one thing he's learned, it's that running never works. So this time, he doesn't wait.

Because....

ITS HERO TIME
