As promised, all spoilers will be under a cut! My understanding of Japanese is very limited, but even with that in mind, there will be plenty of gameplay spoilers and some plot summaries.
For now, all "screencaps" are taken with my phone, since I don't wanna spam my PSN friends with spoilers >< Sorry for the low quality shots!
