Fuuu aren't they!? Actually, that's what I'd like to know too.... I found it randomly looking for KtB images, and it was with a a few other official images, and it looks like sensei's art, so I think it is...? B-But sadly, I don't know where the image actually came from, so sorry ;_; But I do have the original-ish one...?

I want iiiiiiiiiiiit..... Yes, we shall wait and see....
