Try to grab her leg and pull her to the floor

You grab her bare foot as she kicks you and roll and pull hard at the same time, sending her crashing down on top of you. She curses in Japanese and starts to scramble back to her feet.

You could grab her and try to pin her to you so you can roll over on top of her and take advantage of your greater weight - probably the only advantage you have over this girl in a fight. She is incredibly quick, though, you might not manage it. Or you could try to get back up yourself and put some space between you.
