I've been playing around with j.5d~B as an anti air and just confirm off normal hit around midscreenish and a little closer to the corner but not enough to be a near corner combo maybe a space forward in nuetral or back. you can confirm j.5d~b at any height of norm jump and get a combo and knock down in the corner or closer to get the great route she has! so i guess its an anti air too and air whiff punish (Hakumens) !
Mid screen is j.5d~b -> Land -> 5C -> Tk.236b -> j.5d~a -> j.4d~a -> 6C -> 5d~a -> 6C -> 236C~B 3079 damage. Also if you are close enough to the wall you can 4d~6B (Really let it Lounge over!) -> 6C -> 236C~B for 3229 damage
Note 1: to get the combo to work from the top of your opponents normal jump height ie when their head is off the screen like hakumen or hazama for example you need to delay the 4d as much as possible. some times people and in training mode they fall in such a way that its not really an issue but sometimes you can see the space and therefore need to delay it!
I tried this on Hakumen, Platinum, Rachel, and Hazama all worked. tried to get all the types i could think off.
If people were already doing this my fault also if you have something better im open to interpretation.
