"Oh, I guess what you're describing is not exactly what one could call true flight. You mean actual flying with your body, right? Technically, I can only truly due that in one way, and even that's more-well, let me explain."

She wanted to talk more about that strength of his in a moment, but since he'd asked her this specifically, she knew she was going to have to demonstrate. Luz gestured to the staff in her hand.

"This is my mentor's staff, what's known as her palisman sits on top. The palisman can come and go when it wants, but when it's on top of the staff, it becomes one with the staff, and gives me the ability to fly on it, like, say, a witches' broom!"

Which was, in Luz's estimation, pretty fun!

"But the other way is, well, this."

She went into her cape and pulled out a small cowboy hat. She then put the staff down and placed the hat on her head. Luz's body disappeared and was replaced with a crow that was flapping it's wings wildly. It circled around Midoriya a moment before coming down on the ground and then, using its wind, sweeping the hat off. Luz was back in her body, hat in her hand.

"See? Technically, not 'true" flight, but still able to fly!"
