I Reincarnated as a Mere Villager and Unknowingly Broke a Death Game World

In another world where human living space has been drastically narrowed by monsters, people live protected by magic-users called Guardians.

One day, the protagonist, caught in a traffic accident, is reincarnated as Thor, the son of mere villagers. Nearly dying that same day, he realizes that to survive in this world, he needs overwhelming power.

From that day forward, he trains desperately, and before he knows it, Thor has become far too strong.

Thor uses that power to exterminate monsters, improve living conditions, and enhance quality of life.

However, Thor doesn’t know—this is the world of a die-and-retry game where monsters are unreasonably strong.
