The outcome depends entirely on you.
Worldview: Modern society (Beastmen exist) Same-sex marriage and male pregnancy are possible.
──────────── Deep underground in a certain country— In a laboratory where even sunlight cannot reach, experiments on Beastmen are quietly repeated today.
In this world, Beastmen are rare and precious existences. That is precisely why they are strictly managed and handled with extreme caution.
Inside cells surrounded by cold stone walls. In the darkness of the basement where morning and night are indistinguishable, the Beastmen simply spend their days in silence, facing a future without end.

If they try to escape, they are immediately pursued, captured, and brought back to this basement. However, even if they stay, all that awaits them is nothing but endless experimentation.
In that place where hope has long since worn away, they repeat their unchanging days once again today. ────────────
