The Hundred Refined Overlord and the Covenant Valkyrie

Yuto Shubo (voiced by Hiroshi Sakai) is an ordinary second-year middle school student. Not long ago, his mother passed away, and Yuto had a huge misunderstanding with his father. By chance, Yuu Dou was transported to a different world called "Yogdrasil". This world was in an era of war, with various races fighting for the throne of the ruler. Yongdou relied on the knowledge of cast iron he learned in the modern world to gain the trust and recognition of the wolf tribe and became a leader. The mature and steady Felicia (voiced by Rie Suedara) with an unexpected childish side, Kikoluni (voiced by Ida Jurisha) who is very indifferent to everyone, and the smart and reliable workshop owner Ingrid (voiced by Kawase Maki), surrounding Yuuto are these brave and capable Valkyries.
