Frey is a third year puppeteer and Loki's older sister. Just like him, she has red eyes and pearl gray hair. Frey's automaton is Rabbi, a dog-type automatic doll.

She is also an airhead, kind of quiet, and very clumsy, to the point of falling in her own traps. Frey also claims to be a good cook, but in actuality she makes mistakes such as adding too much salt as there was no sleeping powder left.
