Quite a dramatic difference from the Ryo-ohki ova's. they seem to have added more silliness to the story and changed the characters backgrounds completely, and did a total overhaul on washu's personality. She is no longer the deep, calm, and collected person she was in the originals. instead she has become more of a mad scientist with a rediculous ego. though the new storyline is still quite good, the added sillyness and lack of character depth definitly let me down a little bit. but still a good watch.
