I've finally started to get my bearings in this game. Still, it breaks my heart to know that I'm progressing throughout the game without my precious Strarf. So the question is, how do I got about making her available for purchase?
I figured this thread would also be useful to discuss methods for unlocking various other Shinki. To start, I apparently unlocked Ach after beating her in the F3 Tournament (she was 2nd seed).
