Well her offense just STOPS after like a 4 hit block string. She's either going to go for 5B again, pot books / book tray, iad j.6b, or iad j.c (which fails because it will fucking whiff). Without dust she's severly limited to what she can do. And still, H-Hisui can do all of that save throw out book tray but then footstools > whatever she's got to use on the ground in F anyway.
You can see him stop early on a string or two because he doesn't have shit to follow up with because dust isn't available. Then he wises up, but it's still pretty limited.
