Yuusha ga Shinda! Murabito no Ore ga Hotta Otoshiana ni Yuusha ga Ochita Kekka.

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.
