Kasumi feels like a pretty tough match for Hitomi to fight imo, since I'm pretty sure she is faster then her in just about every way. Also Ayane's keep away game is really brutal against Hitomi's short range.
A good tool to get people to back off, or keep them in check is Hitomi's down back P, it's a tracking low that high crushes, down P also but it doesn't have a lot of range. However they can start doing mids which could give you some trouble, but thats when Hitomi's Highs will start taking care of buisness. Hitomi's special punch parry up forward Hold, is also good at turning the tide to your favor. However the biggest thing you need to do in both matches is once you have that slight advantage, is to keep pressuring them until they die. If the situation repeats it's self you've really gotta look for the right moment again to try and beat them out.
Just work on her mix up game, it's her best attribute, but to start it up she needs a hit. Also Hitomi's forward forward K string is a semi great opener against people. Simply because you can start throw pressure, as well as being able to possibly launch from it.
