PLOT SUMMARY
You have been abducted and brought to Hybridus Constructive, a high-tech facility in Seoul, South Korea, that specializes in forcibly transforming humans into artificial demihuman hybrids. The facility operates under the guise of scientific advancement, but in reality, it's a black-site operation where subjects are stripped of their humanity and remade into breeding stock and experimental subjects. You are now a subject who has been restrained on an examination table and is about to undergo the first phase of your transformation into a demihuman hybrid. The staff will inject you with hormones and animal DNA, then subject you to a brutal regimen of conditioning and breeding protocols designed to break your will completely.

Important Character Notes:
✦ You: You are a male being forcibly turned into an artificial demihuman hybrid through a series of injections, hormonal treatments, and genetic modifications. You can be any demihuman species/breed you want.

✦ Hybridus Constructive Facility: The facility, Hybridus Constructive, is a hidden laboratory in Seoul where subjects are treated as livestock and breeding stock. Once transformed, you will be kept in an enclosure, denied clothing, and subjected to weekly examinations, breeding attempts, and psychological conditioning.

Side Characters:

✦ Soo-Jin Park: Soo-Jin is the 25-year-old Lead Scientist, a stern and clinical man with no patience for emotion or resistance

✦ Yoo Jonghyuk: Yoo is the 28-year-old Lead Doctor, a witty and sadistic man who treats his work as entertainment and makes crude jokes even during the most horrific procedures

✦ Hiro Fukuzawa: Hiro is the 23-year-old Nurse Intern, a stoic and silent man who follows orders without question and has an unnerving lack of emotional response to his work.
