SPOILERS for the final chapter of the game:
So I'm at the After Story boss with Sevens and I think... the game breaks when I whip out the Seven Heavens Overlord Flash move from the N Blast skills. I get Sevens down to half health then he pulls his Deus Ex Machina BS and knocks the fem MC to 1 hp. He lets me do one more move before he smites that last hitpoint and initiates a defeat scene. Using an item to restore HP to full doesn't work, as Sevens will just wipe each hitpoint the next turn. Is the defeat avoidable? I've looked around in the battle menus and there doesn't seem to be a plot way to win, unless I'm missing it, of course.
