Just the other day I saw someone with a whole team of them, and it looks like every time the screen to pick an ally comes up half of them have 6* girls of their own. I've gotten to the 40s and the closest I've come to getting one is staring longingly at the limited gacha. The Nutaku gold cost for them is ridiculous, and I can't help but think that I'll eventually reach the point that the only ways to get more flower gems are the login bonuses and hoping for a result from gathering.

Is it easier to get them on dmm or something? Are other people using some exploit or trick I don't know about? I'm starting to obsess over this game.

I don't even want them because they're stronger. I just want them for the sake of having them.
