Yuuto Suwa (voiced by Hiroshi Sakai) is an ordinary second-year high school student. Not long ago, his mother passed away, which led to a huge misunderstanding between him and his father. By chance, Yuuto is transported to a world called "Yogdorasir," which is in a time of war, with various factions vying for the throne of power. Utilizing the ironworking knowledge he learned in the modern world, Yuuto earns the trust and recognition of the wolf tribe, quickly rising to become a leader. Surrounding Yuuto are valiant Valkyries, including the mature yet unexpectedly childlike Felicia (voiced by Rie Takahashi), the cold and distant Jikuruni (voiced by Jurisa Ida), and the smart and reliable workshop owner Ingrid (voiced by Maki Kawase).
