Elza Lynch, codenamed Angel, is a 26-year-old human officer in the A.D. Police Branch division, specializing in deep-cover undercover operations primarily targeting the Genom Corporation. She possesses distinctive silver hair, dark skin, and black eyes. Her core mission involves infiltrating Genom to gather intelligence on corporate misconduct and illegal Boomer-related activities.

During one critical operation, Angel assumed the cover identity of Basil Nikvest's girlfriend to investigate the origins of the destructive Sex Boomer Crusher. Her deep-cover work successfully confirmed Genom created the Crusher and transferred it to Nikvest. This investigation, like others probing politically sensitive conspiracies, placed her at extreme risk.

Angel was assassinated by members of a radical faction led by Kenji Sorime. Her murder coincided with the activation of the Domino Effect Explosion system, a large-scale terrorist bombing campaign across Genom City. Responsibility for her death was falsely attributed to Basil Nikvest as part of a scheme to conceal the true perpetrators.

Within Branch, Angel's role remained focused on covert intelligence gathering rather than direct field operations with the main team. Her intelligence significantly aided Branch investigations into Boomer crimes and corporate corruption, though her deep cover limited interactions with other unit members. Her assassination formed part of Sorime's faction's coordinated series of killings targeting key Branch personnel, culminating in the destruction of their headquarters.
