Some thoughts about Kokoro now after a lot of play.
I find that her two new moves, 44P and 236P+KP are rather lousy moves. 44P has a 7 frame sabaki window and on a successful sabaki of mid punches only deals 20 damage versus the normal 40 damage you'd get if this move hit cleanly (which is probably never will given how slow it is). Although the red threshold is nice, I feel the fact that you can fast hold this basically means there is no real advantage to a successful sabaki on this move. You will almost certainly be held against good players if you go a CB. At best, its just another 50/50 (launch or throw), which isn't really what Kokoro really needs.
Likewise her 236P+KP is a mid mid with a throw heichu mix-up and its not a natural combo, so it can be held out of if the first hit connects. Its pretty much tag-team combo filler since solo combo damage Kokoro has 66P+KP+KP+K. Although the tech crouch property is pretty nice the input kinda makes it a little tricky to whip out against highs.
Finally the sidestep P+K makes a return. I actually still like this move and I still like here. Its easy to underestimate given how slow it is, but that is an advantage. Kokoro appears to move faster than the actual attack, its only half a second later that the attack connects and can put the opponent in a sit-down stun. It can be useful for pressure.
Tweaking Kokoro's 33PP so that the first hit no longer deep stuns (thus no longer a natural combo) and reverting 6P+KP may have done some harm. Kokoro had very few good approaches and even with her new moves (both mids BTW) this kinda makes it worse. Baji Quan is all about approach (see Akira and Leo) so its rather odd that Kokoro doesn't imitate the importance of Baji's stance oriented approaches. All she has is Heichu, which doesn't quite qualify as Akira's "Heichu" is better on all accounts.
