"Get out of the way, or you're going to get hurt!"

Sora is well past the point of being able to abort, and even if she could, Kanonno probably can't get anything productive under her in time. So as she starts to touch the ground, she tucks her legs in and translates the momentum sideways. Unfortunately, she still rolls a good dozen feet plus, coming to rest some distance away. Unless, of course, Kanonno didn't move from behind the flight path, in which case she's going to find her feet swept from under her via Sora's tumble.
