This is a tough MU...
The dive kick is pretty punishable on block obviously, but also on whiff, 10f or something? If she's abusing the OH low string, you can reversal between hits (back dash or armor). If you don't opt for that, but guess right and she goes into military stance, block high as the low will lead to much less damage (for midscreen situations).
If you're pressuring her, you don't have to respect any wake ups since d4 low profiles everything but X Ray (whiff punish leg grab) so check her with that often. The best she can do is reset neutral with ex ark kick whiff (Which is punishable on block so even that's risky).
