Ishida did not reincarnate upon landing in Korova. After all, no one there can truly die anymore.

Along with hundreds of others, Ishida is taken from Earth and tasked with saving a dying world from itself. Naturally, he sucks at it—failing the initiation ritual, gaining no magic, and getting some of the worst rankings in history.

The rest of his group isn't much better, composed of the girl he'd been planning to get rejected by, a healer that wants to be a genocidal demon god, a tank who takes her role a bit too literally, a middle-aged janitor, and a mentor whose parties always seem to die...

The thing is, to get left behind is to see the cracks of the world more clearly: the way local culture is slowly being eroded, the way locals speak to humans in heavily accented Japanese, the way everything outside of safe zones is a lifeless, empty void. Some of the Earthlings are also turning into monsters...

Are they there to save the world, or to get harvested by it?
