50 Rainbow Coins for each pull.
Yes if you are starting from 0 its more expensive then 5K deal to get the 6* you want, but if you already have some and need less than 50% then its certainly worth it.
I took 2 pulls, for 100 coins, now I am sitting at 296 > <
Need to scrape 50 gems somehow. Even pomfed several girls to 100% affection to get more but still need 25 for a pull, and hope to get some 2 dupes (or alternatively the currently featured Plumeria, who I really want for Promtion).
Edit: Can anyone tell me which of the Danchou abylities are the ones that increase speed of the girl that you give it to ?
Need to get FG, and there are those speed based missions I still need to clear. Dont exactly have the best characters for that, but they are currently sitting at around 750 so I figure if I can push it to 800 I should be fine.
