According to the official Twitter account for the Comic Alive magazine's editor, the popular light novel series MG Bunko J, namely 'Madan no Ō to Vanadis' has been green-lit to receive a anime adaptation based upon the first five titles. There was a previous announcement made at Media Factory's Summer School Festival 2013 similar to this, however it was not confirmed when production would start. The light novels follow the story of beautiful girls who ride into battle, wielding weapons received from dragons. These seven beautiful girls known as Vanadis rule over the seven territories and ward off the threat from their neighbouring countries. A boy named Tinguru gets caught up in a battle with the "silver fraulein" Vanadis and is taken prisoner by her.
