Not saying it belongs in the "just fly" pool since fanon goes back and forth on Marisa flying with no broom BUT Marisa can fly without her broom in canon and I'm not sure there's ever been any limit on magic in Touhou. On top of that, Marisa is also either oddly athletic and strong or has some Hijiri-type magic

My magic's run out and I can't fly...But wouldn't it be faster for you to come over here...I'll make some strong flowers right away!
