Well if I can remember somewhat correctly, I believe I came to the DMM side of FKG around late April or early May timeframe. I don't remember specifically how many gacha pulls I've tried. Currently lvl 134 and this is what I have to show for at years end:

11 rainbows (6 natural from gachas)
92 golds

Still haven't finished story mode and I am struggling with whale ship still as I don't have enough of all the types (except for Slice) of girls leveled up to be strong enough yet. I'll have to devote more focus on doing this better in 2018.
