1. Flowering Peach - 50 FK Pull Gacha in July 2016
2. Sakura - Step-Up #1 (8/05 - 8/12): Random (up to and including Daisy) - Used $50 based on Paypal and I believe it was this Gacha since I got her before Geranium's event (26.07.2016 - 09.08.2016)
3. Kerria - Black Friday 2017 Deal - Used $10
4. Mei Plumblossom - Nutaku 2nd anniversary (1/13 - 1/16) - Used $30
5. Astroe Maria - Freebie for 350 Days Login - Got her on June 20, 207
6. Apricot - 50 FK Pull in July 15, 2017
7. Dianthus - Summer Sale Rainbow Gacha (7/26 - 8/2) + 5* Exchange Ticket (7/26 - 7/28, NG only) - Used $15
So I got 2 Rainbow Gurls from Gacha and the rest were NG - it still excites me b/c you never know when you pulled a Rainbow for FK pulls
I wish I can record data and wanna see my statistics on pulls in Nutaku but at least, DMM, I did record all 50 FK pulls
