Shinichi Kanou is a shut-in otaku with a vast knowledge of anime, manga, and video games. One day, after applying for a job in hopes of escaping his secluded lifestyle, he is kidnapped and transported to the Eldant Empire—a fantasy world filled with elves, dragons, and dwarves. Trapped in this strange land, Shinichi is given an unlikely task by the Japanese government: to spread otaku culture across the realm by becoming an "Otaku Missionary."
