Just my opinnion but... isn't the gameplay a bit too boring?, I mean it's just clicking over and over.
Then when I saw the price of the gacha and everything else I was like WTF?!, 5k nutaku gold for 10 characters, basically you have a 35% of probability to obtain UR-LR, if you just think about the LR then a 15%.
So... 30k nutaku gold for a 95% chance for LR... it seems crazy. The funny thing is that I got a 6 star out of luck while doing gacha with the free tickets, got Asagi Igawa.
But well, at least the game has good events or it's better to leave it already?.
