Curly serves as an antagonist for the Fortem Cult, an organization dedicated to disrupting predetermined narratives within Story Zones by transforming individuals into Chaos Tellers. Like the protagonists, she wields a Blank Tome, granting her immunity to fate and the ability to traverse Story Zones freely. Her actions consistently oppose the main group's efforts to restore order, frequently involving direct interference in their missions.

She operates primarily alongside Loki, another key Fortem Cult member. Together, they orchestrate events across multiple Story Zones, including Wonderland and Orleans. Specific collaborations include manipulating Dorothy into betraying her companions within The Wonderful Wizard of Oz narrative and capturing Alice to serve as the core of the Jabberwock entity. During the event "Chaos Galahad's Strategy," Curly and Loki coordinate battles between corrupted fairy tale teams, advancing their goal of widespread narrative disruption.

Her motivations align with the Fortem Cult's ideology opposing the Storytellers—entities scripting fates within the Books of Fate. The cult perceives these predetermined narratives as inherently cruel or unjust, justifying their reality-altering interventions despite the collateral damage inflicted on Story Zones. While explicit personal backstory details are absent, her unwavering commitment to this cause establishes her as a persistent adversarial force.
