Well, that move is a pain cause of the tracking second low kick. You have to guess if he gonna do the low kick or not, there's no guarantee option to deal with it. I tried to block the 1st flying kick and use some jumping mid punch/ kick of some character to crush the low kick but all failed because it's fast enough to get me first (Maybe someone can find a move like that). If you only tend to block the 1st flying kick, that's mean guessing all day everyday, and it's brain killer lol. I suggest a riskier option: spacing and holding the flying kick; two or three holds should make Hayate afraid of spaming this move though.
