I superjump and airdash the moment i see shippu's starting animation (superflash), repeat,
bonus points if the hakumen messes up and i react fast enough to throw out a gravity.
Oh yeah, i forgot to mention, this is assuming the hakumen does 2 kishus after each shippu.
If its just one, well I'd have to play against a haku that did that to find out, but with 2 kishus, if the hakumen gets too close, you can airdash over them safely off of a super jump.
