I am a new player, I saw this game got black rock and hopped on cause ive missed other colabs with her (mainly PGR), but now I have her maxed. I saw they have Reki from BlazeBlue and want her badly, but I only have one copy. I've done the math, and I'll need 27,000 coupons to max her out. All this to ask, what's the fastest way to get coupons in this game?
