I'm going to tell you a terrible secret, but this particular skin/AU/whatever you want to call it, should have been the first planned skin for Uri, because even she herself inspired by this event.
And I am the happiest person in the world, because it was brought to life by exactly the artist I wanted it from.
And yes, her true form is a giant jaguar spirit. She just thinks the human form looks cuter (hey, she just worships humans, so even in her real form, she'd rather lick you to death than actually hurt you).
