勇者が死んだ! 村人の俺が掘った落とし穴に勇者が落ちた結果。

Three years ago a hero sealed a Hell Gate. The seal has been weakening ever since, sporadically letting monsters through. After a big group of monsters entered the country through a Hell Gate, the profession of heroes was needed again. A small radish farmer by the name of Touka Scott is forced to take matters into his own hands and protect the region from attacking monsters.
