If you have the mini, which by the way is basically a huge and popular repack of AA2, you can create those characters. Granted they may be a bit different, but in my game I can create girls with demon tails (to-love-ru), wings that are either demon, angel, phoenix, and so on. It is best if you want is to download cards that have elements of stuff that you like or want, or even characters you want and then you can take those elements, like say a cat tail for example and place it onto a different character. This is a link to the mini
