NEKOPARA (which is a combination of neko, the Japanese word for cat, and paradise) takes place in a not too distant future where geneticists have created the ultimate human-cat hybrid in the form of catgirls. These creatures were created to be the perfect pet: smart enough to be talked to, but cat-like enough to still be cute, purr, and so on. Since many of their feline instincts were intentionally left in place, catgirls are owned, regulated, and treated as pets. A very small percentage of them, generally only the most well behaved, can go through rigorous testing in order to earn a license to be allowed outside of a house alone.
