I shouldn't be rating this after only seeing one episode, but I'll come back and update if my opinion changes. I have good feelings about this and will continue watching.
My favorite thing about this is that it has a great variety of female protagonist that aren't completely sexualized, it's one of the few anime's I've seen with that. Plus their powers are pretty cool.
It has a bit of a slow start, but is still interesting enough to carry the narative. I found the animation was good, nothing spectactular but it doesn't detract from the story. Voice actors I thought were pretty good, overall sounds didn't stand to me though.
