There wasn't much info out there I could find. Unfortunately, google translate of rbgarou.fc2web.com is very...hard to understand at times. No one has ever done a write-up on Sokaku before. The best player for Sokaku I've ever seen is Yor, though he's currently uninterested in RB2 again. I'm going to link him this and ask for some suggestions/feedback so we'll see what happens from here. If anyone else has anything to add, please do so!
