Can match Maito Gai's speed when he has the 5th Gate open.

He did not get her name that first time, but they eventually met again. And again. And yet again, as if fated to fight each other. Sometimes their meetings were completely coincidental; her purpose completely unrelated to whatever mission he was assigned to. But they still fought, and she always got away. At first, Gai noticed, she made her retreat whenever he opened four or five Gates, and Gai figured out that was the limit of her speed. That changed in the last two years, when she proved capable to somehow match his speed even with the Limit Gate released.
