When sixteen-year-old Soren Kojou is abandoned in a deadly gate dimension by people he trusted, he survives six months alone and discovers a strange library. Inside it — fifteen abilities, ancient power, and the inheritance of a being who died sealing a world-ending threat.

Back in the world, Soren builds an empire from nothing, infiltrates the most powerful guild on his continent, and spends two years dismantling a corrupt system that killed his mother and his father before he was old enough to know him.

But the corruption was never the real enemy.

The real enemy came from the gate dimensions humanity has been harvesting for thirty years — patient, ancient, and building its army in the dark. And it’s been watching him the whole time.

Vireon System is a progression fantasy about a boy’s Journey from being the most notorious villain, to the most mightiest hero.
