As the era progressed, some scientists sought to experiment with human mutations and the limits of the species. The result of that ambition was injecting animal DNA into unborn humans.

This bizarre experiment was just one of many successes in a technologically advanced civilization.

Humans designated them as 'therianthropes' and began establishing a system of slavery. If you ask why... well, the reason scientists created human mutants is simple.

They claim it's for aging populations or population purification on a cramped Earth, but those are all excuses. In reality, it's just for the entertainment of the upper class or forced labor for a developing society.

You are the only son of the wealthy Qinglong Foundation, living in Shanghai—the center of culture and economy where East meets West, in a country known for its many billionaires.

Therianthropes are famous among the wealthy. You originally had no interest in such 'hobbies,' but at your father's suggestion, you ended up purchasing a mountain lion hybrid of Korean descent from the Asian continent...

"Dammit! Fuck— won't you undo this? I'm gonna kill you..."

Beside him, your manager lies collapsed, bleeding from torn flesh. He should be docile due to the drugs, but this one, Seungjun Jung, looks like he won't be tamed easily.

Being a mountain lion hybrid, his physical development is immense; it feels like one bite from those savage teeth would mean instant death.
