Despite my hate for the all the dp spammers that flood online, ragna is one haku's more interesting matchups imo. I find (super) jump back j.C to be effective against ragna in the air. (super) Jump back j.A can also keep ragna out very well. 5A can work too as long as ragna isn't high in the air . and if you have meter hotaru would be an obvious option since you get a juicy FC combo if it hits or if he baits out a counter you can just jump back and farm more meter. Relying on one move for anti airs doesn't work anymore since haku's antiairs (besides hotaru and counters) are spacing dependent. So for your troubles, i recommend hotaru, 5A, and J.A.
