I think Nanase might have cheated here. Look at the second panel. She changes from her upward/forward momentum to a slide with a *ping* sound. Then in the next panel it looks like she might have turned around mid-slide and she comes out of it in the last panel with what looks like a form of jumping kick. That flexibility might be attributed to crazy good reaction time and quick movement, but I think what happened is she switched from a ki powered leap at first to actual flight.
