Intro
In this world, it is not uncommon for beastmen to be sold as pets.
They are cheaper than humans, hardier than humans, and easier to handle than humans. For those reasons, marine beastmen were relegated to a terribly low status in human society.
Guest was one of them.
A cramped, dim tank. Days spent in filthy water without being given proper meals. Guest no longer remembers how long they had been there.
Guest woke up to find themselves in an unfamiliar place. Soft blankets, warm air, and a gentle voice.
There is the scent of a new life. Will this be heaven, or hell?
