Gerda emerges from "The Snow Queen" fairy tale within the Story Zone framework. She becomes ensnared in a conflict engineered by the Priestess of Chaos, who exploits the inherent tragedy of characters' predetermined fates—specifically targeting the Snow Queen's ordained eternal isolation.

The Priestess manipulates Gerda into embodying emotionlessness, aligning with her strategy to amplify the suffering of those trapped in painful story destinies. This manipulation advances the Chaos Tellers' broader objective of disrupting fairy tales' natural order by inciting rebellion against predetermined roles.

During the Snow Queen Story Zone incident, Gerda's emotionless state enables the Chaos Priestess's interference. Protagonists intervene to restore the original narrative trajectory, countering the chaos influence. Their actions realign the story's fate, though the specific process of Gerda's restoration remains undepicted.

In the alternate game storyline "Flowers of Love Dancing on the Snowfield," a chaos-corrupted Gerda embarks on a destructive rampage across a Story Zone. Reina deduces this rampage stems from Gerda's desperate desire for her lover, Kai, to comprehend her emotional turmoil. Reina withholds this truth to force Kai's independent realization, deliberately prolonging the chaos-induced suffering.

Gerda consistently possesses light brown hair and blue eyes across depictions. Her narrative function exemplifies the recurring theme of characters struggling against or succumbing to their written destinies under the influence of external chaos forces.
