That's a good question...

Maybe it's Molecular Displacement. She isn't fast, she's literally teleporting by shifting her molecules. What appears to be massively increased strength (like cutting down that tree) is actually her creating a molecular displacement field around Crimson Rose's blade. It would also explain why it can do nearly-impossible things without getting gunked up between the two sides of the blades because her Semblance is creating an invisible extension to the blade.
