Current #66 in the Duel Chart.
A pair of sisters who have managed to summon a Servant of dual existence. Freki, the older sister, is in charge of the male Servant while Geri, the younger sister, is in charge of the female Servant. These two, despite quite a bit of gap in their age, work as a perfect team. They are both merciless and cold as the mountaintops of Norway from where they hail, and one should not expect any quarter given when fighting against them.
Freki is the older sister.
