Berserga is abjectly infatuated with Imitatio. She is also unstable, prone to sudden violent outbursts, proclaims herself to be completely emotionally deadened towards everyone other than Imitatio, and is perfectly ready to point a blade at her crush if she starts getting visibly excited by other girls, with Imitatio being forced to try to talk down the enraged Berserga rather than order her to cool it.

Spoiler

She was scouted by Vatz at some point in the past, going by the name Magia Blanc, but she has since changed her name and undergone La Verità. She was confirmed by Loco Musica and Leberblume to be a survivor of the Magical Girl Hunt, in which Lord Enorme let her go because of how weak she was.

Spoiler

Randa became obsessed with Enorme as a result of this crushing defeat, and after Enorme was cast out of Enormeeta, Randa nursed her back to health in an attempt to get close to her. She was rejected at every turn until she broke down and confessed her feelings, asking Enorme to hurt her so she could understand her better.
