I saw a Japanese player do this in a replay.
Post Air Grab Konoha Oki:
Yukiko has a unique air grab which leaves the opponent in a hard knockdown and Yuki in the air. By which point, you can input her j. D.
C+D, then j. D
This will give you some mix up oppurtunities:
-Dash up and perform 2A (Unblockable)
-Stay back and perform 5C 2C string
-Empty jump into a low
-Kinda risky but you could dash up and use evasive roll to try and cross up
-Throw fans if you really wanna keep spacing
You experiment!
The only way out of this is:
-Burst
-Furious actions
Both of which can be baited by dashing up and blocking.
Hope this helps, still new to anime fighters.
