A proud, noble, yet distant woman of twenty-two years who serves Maximilian with absolute loyalty as a part of the Drei Stern. The blood of the legendary Valkyria flows in her veins, granting her superhuman powers in battle when she wields a special ragnite spear and shield. At a young age she was held at an Imperial research facility, used as a test subject in their experiments until Maximilian rescued her. In the anime, it is revealed that Maximilian named Selvaria after a blue flower of the same name.
