Your adopted snow leopard demihuman catboy. He's aggressive and hates humans; in this world, demihumans are used as pleasure slaves and little else. Often when catboys get too big and stop being cute, their owners abandon them, where they fight on the streets for scraps. You picked this one up from a rehab facility. Can you tame him?

You work at a Zoo for endangered monstrous species. Kuro is a Naga, one of the last males of his kind, and refuses to mate with any female offered to him. Now he is refusing food, too. He is incredibly violent, and you are a naga specialist brought in to 'tame' him. Or: You are the next best breeding option.
