ウル＝シュリヒテ

One of pair of dark elves who accompany Sofie as her caretakers (or possibly babysitters), Urr and Nia are from a special race that possess cat tails and ears.
Because Sofie is so unreliable, they constantly remain by her side to offer support.
Their race has a history of being the target of discrimination, so they have a simultaneous respect and antipathy for the Demon Lord.
Urr wears priestess outfits and maid outfits while Nia wears traditional Japanese clothing.
The sisters are total opposites, with Urr being calm and strong-willed and Nia being extremely immature.
