Just a random theory of mine (I know it's off topic but, whatever)
OK, I know I'm jumping into conclusions soo fast but, this is just a theory... So read with caution pls
Just like Aikatsu and AiStars in season 2; they all have wings...
1st Aikatsu's Wings were all about Constellations, then AiStars were planets... So what if, in the season 2 of AiFriends' Wings were Gemstones?... I mean in season 1 we already have some kind of connection or reference to it : DIAMOND FRIENDS... Or mabye it'll just end up just like Akari's Gen XD
I'm just saying... This isn't real, it's just a theory and my opinion... So pls don't be mad...
