Unreg - you are correct. For some reason it didnt show for me before.

Paraphin - It works this way - for every gacha pull you do, 5* and 6* duper give you small amount of Rainbow coins. You get 300, you can exchange them for a free rainbow on that list.

Now this mechanic has been on DMM for a few months. And I´ve burned around 1300 gems over that period, and at this point I am still only at 216. And lets be clear here. You get about 3x the Flower gems at DMM that you get on Nutaku. So for Nutaku players this is a quite a long time objective.
Definitely dont expect to have those 300 coins within few months.

Unless Nutaku somehow monetizes this and sells it as a daily deal, or part of a bundles, or something. :P

Rainbow medals have been around for almost exactly one year, actually.

The details are in the Patch Notes below the game window. I used Google Translate to get the geist of it, but I am still not sure what is the currency they are talking about. Seems to me like you need 5 Danchou coins to exchange for some sort of Rainbow currency. Once you have 300 of it you can exchange it for a rainbow ticket (or directly for the girl in question). Or something like that ?
Anyone with JP skill might wanna take a look at thi ?
