This guy can send you back to the start of the fight very easily on Very Hard if you can't hit these parries (I'm not sure how it is on the lower difficulties). In case anyone did not want to go through a fight just to (potentially) die to him, I made this practice video. I would also encourage people to use the in-game practice mode but of course that doesn't help when you're in the middle of a stage.
Fortunately, you really only have to worry about that second parry. It's fairly awkward, but you should get used to it in no time.
