エドワルダ

A fearsome terror from a mysterious land from beyond the sea, and a fearsome female knight clad in black. Heir to the throne of her motherland, she is capable of summoning and wielding the Sword of Mercy, Curtana, as proof of her heritage. But her demeanor could not be further from her sword’s moniker. Night after night she sets out with her attendants, hunting down the Silhouettes for no reason but to satisfy her twisted delights. [From MangaGamer]
