Speaking of which, you might want to do DP to get 500 Alyssa Coins so that you'll get free shit in Kamihime once the cross-over event is finished. Or maybe just 300, since getting 500 only nets you a crappy Dark SR.
Is the free shit good? That almost sounds like too much work. How long does it take to get those 300 coins if I've never played DP before? And how many days do I have?
