"Every morning, she practices her magic on the outskirts of town" (Page 4)

That's one thing I really like about Nanoha as a character, she still trains even after the threat has been eliminated, really shows how hardworking she is. She isn't like other protagonist who take it easy during the peace time and get screwed over when a new big bad comes, she's does this so she can save everyone when the time comes.
