Esper Zero

Esper Zero was discovered near the core of a major Anomaly incident in New Helios, where Esper Zero was initially suspected to have ties to The Circle. However, upon recovery, Esper Zero was found to have no memory of her past, making her origin unknown. Due to her unknown past, unique but undetectable nature, and already awakened her power, Esper Zero was placed under strict observation — effectively a form of house arrest — on Groth Island, within the prison facility known as the Jail of Hethereau. Esper Zero is a unique existence among Espers — the only one in recorded history who remains completely undetectable under the Wertheimer Index, a standard system used to measure Esper activity. This makes her both highly valuable and difficult to analyze. Due to an exceptional sensitivity to anomalies, Esper Zero is also known as the “Appraiser.” This ability allows her not only to sense anomalies but also to quickly locate her Nexus, making her specially effective in resolving anomaly incidents. She maintain a pragmatic balance between conflicting groups (Bureau of Anomaly Control, Eibon Antique Shop, rogue Esper cells). While loyal to Eibon as her newfound "home," she refuse blind allegiance to any single ideology.
