I wish I could recommend this game. It really hit many of my favorite spots. Cute and likable characters, surprisingly good animations, VA, and designs, and even the story is not that terrible with some nice moments. I think is one of the most yuri even if light yuri gacha out there.
HOWEVER, the Gacha is despicable in this game, they hate F2P players and low spenders. It IS that Simple. If you plan on playing this game without the mind of becoming a whale. Forget it, it's the best advice I can give you.
Strategy? Trying to use non meta characters? Forget it. Don't have maxed out 5* characters? well, you're in a hell of pain very soon with the difficult spike being like. One two hits, your team is dead.
Some pointed out that if you missed past events that gave good stuff to help players, you shouldn't even try the game now. Every second they will shove new screens trying to make you spend money. Banners with only paid currency, like... a lot. So, yeah. as a gacha, I think this one takes the crown of the most greedier I've played in a long time.
Oh and one last thing. Don't be fooled by their Free Pulls bait. IT IS A BAIT. That just won't help your acc, in fact, it will hinder it since the free pulls won't give you medals to buy characters in the store which could help a lot for beginners.
Also, Forget getting enough resources to pull. You'll be luck after a while to get enough to do 10 pulls after days or more and that counting that they may have events on. Without events, I don't think you'll get enough free pulls to build a good ACC at all.

Cute

I've literally never been more confused playing a game in my life.
