Mauver

You're not punishing her mistakes enough. When she screws up her ground distortion and you block it, go for a 5C counter hit into 6C instead. That leads to way more powerful followups afterwards.

I also find that deliberately whiffing or delaying certain moves to stimulate a drive against Hakumen can be a really effective tactic against the drive-happy types. A 214A from medium range or 214B from long range, ice car to a finish line just short of a countering Hakumen followed up by 5C counter hit into BnB results in much fun and entertainment. Very satisfying.
