i find itsuu(AG w/e)>A works ok in my experience, as they're usually jump cancelling afterwards, which leads to combo for you
but if they are just trying to hit you raw, they like to cancel drive (before or after hit, kinda matters?) w/ B, to go through. which isnt so terribly good for litchi if u got itsuu stance with your back turned
although, i've found itsuu>C to randomly hit people behind me somehow. prolly char specific.
