The Zerg Overlord of the Crossover Universe

A boy who embraces "the pursuit of happiness" but has lost interest in real life wanders between worlds with a System called the Overmind, fused with the Zerg, searching for emotions that reach straight to the heart.

He leads the Zerg to achieve the first rebirth of a race in a world overrun by zombies.

In GATE, he takes on two worlds at once, bringing the terror of the Zerg back to the world.

In a world infested with Gastrea, he seizes control of the world and successfully integrates the Gastrea virus into the Zerg genetic chain, putting it to use.

In the world of No Game No Life, he ends the war between the races and successfully claims the Star Cup. He boldly announces to the world and its sixteen races that a new race, the Zerg, has arrived and is rising to true greatness.

In the Little Garden, the Zerg's presence keeps spreading. Even the gods have to give them a wide berth, and the entire Little Garden trembles as it faces the terror known as the Zerg.

The boy, Overmind of the Zerg, is at times a savior who delivers all living beings, and at others a demon king who wreaks havoc across the world.
