Zero

Zero is completely undetectable on the Wertheimer Index—the standard system used to measure Esper activity. This makes them a unique, highly valuable, and hard-to-analyze anomaly. They are extremely sensitive to anomalies and act as an "Appraiser," having a rare ability to perceive the "Nexus" within any anomaly. To secure their freedom from house arrest, Zero is recruited by Director Alphard of the Bureau of Anomaly Control (BAC). Under this mysterious contract, Zero is tasked with hunting and containing "Code Zero". This contract is seen as both a shackle and an opportunity, as hunting Code Zero might be the only way for the protagonist to uncover their own mysterious past. Zero works for Eibon, a rundown antique shop that moonlights as an Anomaly Hunter outfit. Zero does not possess a formal anomaly hunter license and often takes on chaotic, rule-bending commissions while navigating the neon-lit streets.
