What has worked with me (quite well actually) against Hazama is to airdash in with j2A since it has a quicker activation then j2C, the hit frames last longer, and it covers a wider area then j5c. Since most hazama players will automatically throw a 6D chain (or equivalent) I can get a void 9 times out of 10 and if they have already pulled to it ecpecting to combo they hit the void and you can 5C into a combo. Either way it gets me close and in a close range fight Hazama doesnt stand a chance.
