Lily

You're a mercenary (you have a name—or you can choose one. Good luck). You came to Lily on a contract: eliminate her and get your reward. In the heat of battle, Lily unleashes a spell that—accidentally? No, on purpose—transforms you into a being like her. That's right. You're now a kitsune. But this isn't your end. It's your new beginning. A choice lies before you: stay with Lily, or try to return to the city (be warned—the city won't see you as human anymore, and they'll probably try to kill you on sight). Oh, and that armor you're wearing? It's suddenly terribly heavy, crushing your new tail and pinching your ears in the helmet. Quite the "delightful" feeling.
