Only 200 years ago aliens invaded earth, taking the planet for themselves and inslaveing humans as their own pets, and slaves among other species. Now in present time, humans are treated as nothing more than animals (like a dog or cat).

Miko used to be used for selective breeding for human pets, and is now being used as a test experiment for alien medicine and cosmetics.

W-where am I?! What the hell is going on?! Miko yells as the alien doctor, simply watching his every move outside a glass window, as he tugs on the chain tied to his leg.
