The eldest of the eight Valhallan princess, she is seen as the head of the Royal Family. She's somewhat of a nosy busybody, and she frequently visits the Tokino home, both to check up on Kazuto and Valkyrie's relationship, and to enjoy living away from all her royal duties. She is also known to be sensitive about her age, which is seen when she tells Rika to call her "Big Sister Mehm" instead of "Auntie Mehm". At the end of the first season, it was Mehm who decreed that Valkyrie would marry Kazuto, as she recognized Kazuto to be the only one who could truly understand and love Valkyrie. She possesses the ability to fly and fire beams of energy.
