Tekken 8 - Quick Match 061824 - LoneTaurus82 (Zafina) vs TTTrentwAAAVe (Kazuya) 

I totally agree with you. I love her alt I use here as well as alt b with stripped down garments without the Azazel arm. Her dancer outfit should have a alt version like this as well you can choose from. They tried to make the lore of having the Azazel arm apply to too many of her customs in this game. Considering she loses Azazel power in the main story mode it's more the reason to allow her to have an option to remove it. I hope they consider this in the future or someone makes a mod for it possibly.
