It actually has GREAT invulnerability (when attacking). But it's not a 1F start up so it's not a true reversal. It's an amazing AA for Hazama. You can try stuffing it before he does the kick(in his 214D stance). This move is also unsafe on block.
Or if youre talking about his Kick Super and not his 214D~B, It has lame invulnerability, but will almost always leave him with the upperhand on trades. He usually recovers from most staggers off that trade and can continue his combos as normal.
In summary, Block the Super and if you're fast enough, stuff the 214D~B (before he can push B) for a CH. Blocking 214D~B is good too.
