Eis is the younger sister of Geweih Metzelei. She is a member of the Pentagram, a group of Invaders that determines how the Invaders are sent for their space invasion plans, Unlike her older brother, who specializes in extreme heat, Eis is the polar opposite of him, as she specializes in extreme cold. She generates bone-chilling ice all around herself, walking on ice to keep her beauty and generates deadly shards and tornadoes to attack enemies. She does not get along well with him.
