Madan no Ou to Vanadis

In a war-torn region of Western Europe, Eleanor "Ellen" Vertalia, one of the Vanadis of Zhcted, leads an offensive into Brune. The Vanadis are seven warriors, each given a powerful weapon by a dragon to rule over a separate territory. Their strength instills fear in those who oppose them. Tigre, a young archer serving as an earl in Brune, encountered Ellen in battle and was defeated. Instead of killing him, Ellen spared his life after recognizing his skill and requested that he serve her in return.
