Typical bullshit anime-original ending. Let's just kill off everyone for the sake of killing everyone off.
Let's have a highly trained assassin killed off by a fat old man with a pistol even though she was in arms reach of him(also, gotta love those flintlock pistols that somehow have an entire magazine of bullets...somewhere).
The fight was awesome though. There was a lot of Lee Vs. Gaara in it. Only with ice instead of sand.
That's dumb. Esdeath would have destroyed the ENTIRE Rebel army before the day was even done. They'd have lost before she needed to eat or sleep.
