勇者死了！ tells the story of Tōka (Takashi Kondo), a somewhat lecherous farmer who is reincarnated as a hero to save the world from monsters that are still invading humanity today due to incomplete sealing of hell. With the help of his allies like Goshima (Toshiyuki Toyokawa), Ayahama (Yuka Hirata), and others, he must use his newfound abilities to defeat the beasts and bring peace back to the land. The series is based on a light novel written by Sadao Tsunamoto.
