Yea, I missed that part about the Wukong skin. The monkey king story is chinese though, not japanese, if I'm not mistaken.
The chinese zodiac doesnt offer a lot for leona though.
Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig

As much as I'd love a bunny skin, it doesnt fit for leona, so I guess it's tiger or dragon ?
Dragon is kinda oerused I feel, but it would fit the fire theme, but tiger might be fine as well.
