At least you still have Oswald's side of the story! Perhaps there will be some surprises there.

If nothing else, GrimGrimoire has zero grinding because it has zero leveling, but it can get a little on the complex side. For me, it was the perfect blend of planning and chaos, but then, I kind of like the hectic nature of Gensui V's map battles while most everyone else seems to hate them. XD; Maybe I'm destined to stand alone in my fannish love.
