An accident transports him to another world — only to discover it's the world of a game he used to play, and what's worse, he's been reborn as an expendable character destined to die early in the story. To defy this fate, he desperately leverages his game knowledge to grow stronger — eventually attaining unparalleled strength, he throws himself into the conflict on a continent facing a Demon Lord invasion.
