Valkyrie "Female Warrior, Lady Fighter"
About
It is rare for a demon to have the potential to become a Valkyrie, but those with potential are taken in as the single apprentice of a retired Valkyrie and are then known as a "Liebe". The Liebe then goes through tough and intensive training which teaches them fighting and survival skills. Due to the hardships associated with their training, Valkyries tend to have a tough personality. Magic Knights are said to be a subgroup of Valkyries.
