Planet of the Orcs Vol. 1

A high octane portal fantasy set in a world at war between orcs, armed with guns, and magic-wielding humans.
He was fifteen when he first became a hero, blasted to another world by an unknown entity. At the end of his harsh and hapless journey, the hero defeated the Demon King. Over the next ten years, he was sent off to different worlds, and every time, he saved them. Now, on his thirteenth world, the enemy is the orc race whose highly advanced civilization has forced humanity into a desperate struggle for survival. What’s more, the orcs seem to have banded under a cunning leader. Has our hero finally met his match?
