Thru luck or $

The only rainbow unit that I got from pure flower gems was Flowering Peach. Sakura and Kerria I bought - can't remember how much Sakura was (hoping it wasn't 50 bucks) but Kerria was $10 for the Black Fri deal which was the best deal

The first day playing the game, I got the 6* girl from the first pull yolo and guess what, she's the one appear in the ad on nhentai that had lured me playing this game. I think I wouldn't playing a web game for so long if that didn't happen
