It's really not that hard to understand, and it's very well told. I'd go as far as saying it's one of the better JRPG stories out there.
The bolded part especially boggles my mind. The exposition (character background) is very well told. The actual plot of the game (end of chapter 9 onwards) is so thinly developed and haphzardly strung together that I had trouble caring even the tiniest amount.
