Jeanne is a hero within the dreamlike space of the combat providence analysis system known as COMPASS2.0, where heroes partnered with humans must fight to generate the energy required to sustain their world. Her character draws from the historical figure Joan of Arc, and she is depicted alongside other heroes such as 13 and Reiya. Early in the narrative, Jeanne is introduced as a determined and stubborn combatant. She is shown to be experiencing a difficult period, specifically a prolonged losing streak in her fights. Despite these consecutive defeats, her defining trait at this stage is her refusal to take time off or rest. Her stubbornness drives her to continue fighting even when it might be more prudent to step back, showcasing a personality that is persistent to a fault.

Jeanne primarily serves as a fellow hero operating within the COMPASS2.0 system. Her role in the story becomes more directly intertwined with the main plot as a crisis unfolds. She is mentioned as joining forces with the protagonist 13 to pursue a character identified as Bugdoll, who is believed to be the mastermind behind a virus threatening their world. This collaboration indicates that despite her earlier struggles, she is a reliable and active participant in confronting major threats.

Information regarding her deeper background before arriving in the COMPASS2.0 system, her specific motivations beyond the immediate need to fight, her detailed personal relationships with other characters aside from 13, and her emotional development over the course of the series is not available. Likewise, a detailed account of her specific combat abilities and powers is also not documented in the provided information
