Yuumi, looks like a cute cat... leaked by a YouTuber name Natseey as shown below in the screenshot. I think he play tested the champion at Riot HQ and made a video for it to upload faster.. and be the first one to release guide for..
I like the champion from it's look, kinda looks like Dragon Trainer Tristana tho..
What do you think ?
now we just predict how op she will be heh
