Against Ayane, from my experience from facing Xdest. You got to pressure Ayane a lot and not let her get in her own range, cause that's where she shines. Punish her unsafe strings. If she force techs you with PP2PK (I believe the string is). Most Ayane's go to move is 66KK so if you see the 66KK You can hold the mid kick, but if you decide to block instead, most will go for 2P since on CH it stuns a bit, but if they go for 4P punish that, and if they go for her sweep, block it and punish that as well or hold it since it's kind of slow.
