Spent all day today on this. I unlocked and completed Futaba's Palace.
That storyline was just incredible -- and Futaba's crowning moment of awesome at the end was just ::chefs kiss::
The boss fight at the end of the Palace was long and drawn-out and I'm very glad I'm playing on easy. The SP management was bad enough as-is. I fear what it would be like on normal.
This is a pretty good game, it turns out.
