Elfreda Mirjasdottir

Elfreda Mirjasdottir, usually called Effie, is part of Lotte's all-female staff and serves as one of the princess's confidantes. She comes from a noble race with cow-like traits, including the ability to produce high-quality milk, and wears a bell around her neck. Effie is generally kind and is often seen with Griselda or Judit while watching over Lotte, Asuha and Naoya.
