Had ~80 tickets, decided to spend all until I get a few golds or rainbow:
I actually cannot believe it. Not only did I get another Rainbow from the salt tickets, but I also got the one girl I wanted from this game! Actually insane luck for me to get
Habranthus of all girls, the very first rainbow I've ever gotten on Nutaku <3. This actually makes my 550 Flower Gems wasted trying to get Onci Valentine not feel too bad.
On a side note, my luck with tickets is actually insane. I can rely on them more than Flower Gems at this point.
