Ariel has been my favorite Disney princess and the little mermaid my favorite Disney movie ever since I can remember! This is most of my collection that has managed to stay in tact for about 5 to 10 years on average.
I have every playable Neko so far, not all of them are at full limit break though. Should I save my gems for when new nekos drop or try to pull more doubles?
EDIT: I was being a bit impatient and jumped the gun on this question, I have my answer now! They are winter uniforms.
Original Caption: I'm betting the reason is they're planned to be buyable outfits, but does anyone have any other guesses?
