Yeah, I just finished the series (it's only 12 eps, a real quickie of a series) and it's a show that almost parodies the 'power of friendship' trope. Even though the power they have is rooted in technology, the strong friendship is still emphasized by the scientist that created it. When the protag first gets her suit, her friend got it at the same time so there's literally no point in the series where anyone is fighting alone. Speaking of alone, that's that the alien enemies are called, just "Alone", and true to their name, they always attack alone, only ever phasing into existence one at a time.
And I say it's a fanservicey series, but there's nothing gratuitous. Just frequent and unnecessary close-ups of butts all the goddamn time. Not even panties, just butts. The literal very first second of the very first scene is a butt. And everyone is wearing short-shorts as part of some in-universe mandatory dress code, but other than that everything is actually very cutesy and tame. Still though, I'd feel a lot less embarrassed trying to discuss the show if the service just wasn't there, but that director just has an obsession that he can't get out of his system any other way.
For a rando anime I picked up for no reason, I'm not upset at this one though. Was fun the whole way through.
