I've never seen Aikatsu in my life but this makes me want to, is it any good for yuri (or even just as a series)?
There's definitely a good range a gay moments, but you have to bear in mind this is very much a series targeted towards young girls, which means a lot of cheesy CG dance sequences and flaunting of merchandise, not to mention there's quite a large amount of episodes for each series. If Precure hasn't given you an immunity to that kinda thing yet, it might not be for you.
