This game is much better than I expected

Honestly, I thought this game wouldn’t really be all that but it’s actually pretty good. The gameplay is nice and smooth, of course the character designs are good and it’s just fun to play overall. I can see myself actually continuing to play this game for a long time. My only problem though is that there are way too many micro-transactions. Even by gacha game standards, there’s a lot. On the other hand, the developers are very generous as the free rewards are quite good which is not exactly the most common in some of the big name gacha games. Either way, great game and I swear I will get Asmodeus when she comes back.

Good game that suffers from common gacha issues

Played this game for several months but finally gave up after several banners seemed to be getting worse in drop rates. I knew this game was really bad on micro transactions, but it seemed to be getting worse. I pulled on several banners over 200 times and no 5 star dropped. You save for weeks and when don’t even get one, it really bums you out. You get a pity character but you need two just to make them usable.
Leveling characters takes forever unless you spend money. The story is decent, but is really slow at releasing, which is odd considering the episodes aren’t even voiced. Though I had a feeling there was more to this game when I started, it apparently is heavily censored on IOS. For a game based on a ecchi anime, it loses a lot when half the game is missing. Which is odd as Azur lane and especially NIKKE out lewd it but don’t have to remove part of the game.
The devs obviously do not care because every response I’ve seen is a automated response to every issue no matter the problem. I’m glad I stopped spending on this game recently because it just a waste when even money won’t get you what you want in the game.

The game itself is good but it have a fair share of problem

First let me get thing straight, this game is great, it have everything I like and expect from a typical gacha game and the free rewards and events are not that bad.

So let get straight into the problem why I give this game a 2 stars rating( note: I will update this review depending on dev’s response). This game have some serious loading issues, I don’t know if it only a problem on IOS because every time I play this game on my PC it work fine but a moment I tried to play it on my phone, the game just doesn’t want to log in and I have to close the app and open it again multiple times just to log in. It also have huge problems when it comes to in-app purchase, every time I buy some pack, it took the game 8-10 hours to process my order and sometimes it took a whole day. The game itself is fine but if those issues are not getting fixed, this rating will remain the same.
