Containment Protocols: Due to its physical vulnerabilities, RPC-644 it is to be held within a modified humanoid containment cell located in Site-008 designed to minimize the risk of injury or contamination, with easy access for the on-call medical staff. The anomaly requires a highly concentrated liquid diet designed to minimize byproduct buildup. Regular psychiatric appointments are to be scheduled on a biweekly basis to satisfy RPC-644's psychological needs and avoid mental deterioration, in addition to a daily checklist of household tasks.

Description: RPC-644 is a Japanese female in the late 20s with no visually discernible abnormalities. The qualities that distinguish RPC-644 from a non-anomalous human arise from a combination of internal biological alterations of both mundane and anomalous nature, as well as indoctrination and behavioral programming.

The physical modifications extend down to the genetic level and include, among others, the integumentary, gastrointestinal, urinary, and cardiovascular systems, as well as the bone marrow. The most significant changes and their effects that have been documented are listed below.

The resulting changes indicate the end goal of increasing attractiveness and minimizing waste or impurities normally produced by a healthy human body at the cost of independent survival. This biological anomaly is incapable of employing many of the repair mechanisms present in the human body, necessitating transfusion and specialized medical treatment in the event of an injury. As such, non-invasive research methodology is highly encouraged to reduce complications involved in otherwise trivial procedures such as injections.

Psychological alterations are present as well. Although not expressly revealing overt modification as is the case in other parts of the body, specific areas of the brain experience reduced activity. Among others, functions associated with the medulla1 or the hypothalamus2are selectively suppressed; the amygdalae3 are nearly completely inactive. This appears to be the result of both chemical and 'mundane' treatment designed to sculpt not only RPC-644's body but also the mind. The most significant outcomes of these changes are listed below.

RPC-644 is effectively harmless whilst possessing a very limited mindset directed entirely towards subservience. The neurological changes have been ingrained to the level where, if unable to perform the programmed duties, it will become increasingly anxious and paranoid. This is the only known instance of the anomaly expressing strong emotions.


Following the injection of undercover agents into the Japanese criminal underworld during 1980s, the competition between the country's yakuza5 and Kabushiki Kawaii6 became all the more apparent. Clashes over the market share of human trafficking and prostitution have reached a boiling point in the early 20██ with the ██████ Family pinpointing a KK customer in the Aichi Prefecture, resulting in an armed clash involving MST Whiskey-9 ("Lab Rats").

Supported by the autopsy reports the customer, ████ ████████, was in possession of multiple entities similar in design to RPC-644 as well as one reminiscent of RPC-880. Before Whiskey-9 was able to take control of the situation all but one of the anomalies were executed by their keeper whom committed suicide shortly after to avoid capture. RPC-644 was found in vicinity of the corpse, apparently mistaking the expiration for rest; no resistance was put up during the extraction. The relatively normalcy of RPC-644 and identity of the customer solidified the notion of KK appealing to a less extreme customer base as means of exerting influence, with the operation having confirmed the existence of an entire series of these specific anomalies.

This eventually led to the conception of Project Lotus7 as a counter.
