>>715897261Subversion of a Magical Girl story where the girls are being taken advantage of by the typical mascot creature.
I'd go in as blind as possible but yes, it has a strong story and cute girls and probably is a good bet for you if that's what you're into. It gets intense.
The first arc of the gacha is an adaptation of the anime it's based on. The anime is definitely the better way to experience that initial story but not 100 percent necessary
