Buy every gear available and level them up as well as the ones you get from those amiibo. Not too hard xD Maybe just try to reach A+ rank. I'm not sure if I have the patience for S/S+
Reach level 50! I'm only at like 36 just now I believe. I don't play every day, maybe a few hours ever couple of days but in no massive rush. Also would like to get to at least A+ rank but I can't see that happening...
