A-054 Mantis

CACG Subject File
Subject A-054 is a female human of indeterminate descent. She is approximately 22 years old, being 20 upon establishing initial containment. She was contained shortly after turning herself in alongside Subject A-053 ("Zero"). Like A-053, she was subject to an anomalous medical treatment that gave her anomalous abilities, at the cost of rendering her mute. Medical examinations performed on A-054 have revealed that this inability to speak is neurological, but it has resisted all current attempts at treatment.

A-054's anomalous ability allows her to silence all sounds in a 5m radius, no matter the source or decibel level of the sound. This ability has made A-054 a nearly-perfect assassin, being able to silence her own footsteps to get the drop on possible targets. She can use this ability as she pleases, but it has been found that it may activate should she feel threatened. Like A-053, she was formerly employed by Chuckleskull Tactical Solutions, and seems to feel wronged by them. It is unclear if Chuckleskull is aware of their current status.

Similar to A-053, A-054 was carrying personal weapons that were confiscated upon containment and stored within High Security Armory B1. The main weapon is a modernized form of naginata, used in tandem with a dangerous wrist-mounted razor wire. It's assumed that the naginata was used for open combat, while the wire would be used to covertly dispatch targets. Like A-053's sword, the naginata and razor wire has a particular lack of technological components. The naginata is composed of a high-strength alloy and mounted on a retractable polearm, while the razor wire is mounted to an automatic retraction assembly with variable control. The composition of the wire itself remains unknown.

A-054 has been approved for both housing and Level 2 credentials within Geo-7. Like all other humanoids, she is permitted a weekly health evaluation with Dr. Tenma, as well as food, drinks, and clothing. Despite her problems with communication, A-054 has been extremely amicable and cooperative with CACG personnel. Since initial containment, she has caused little to no trouble. Because of this, she's allowed to roam Geo-7 freely when she is not needed for evaluations or tests.
