You can't get ahead if you don't take risks! That would be her simple response to Diamond's concern toward her dive. That's just a fact of life, work... and apparently rooftop races between magical girls.

Wow, she's good though! Apparently there's something to be said for experience! She glances back as Diamond's push keeps her right on her heels. She flashes another grin before jumping again with all her might and zooming off into the air.

... But risks are a fickle thing and experience and simply mapping out a landing point are pretty important things to have. Much more important than letting oneself get wrapped up in a race. It's a second too late before the wide-eyed realization hits her that her current flight path doesn't... actually... include a roof to land on.

... Oh, crap!
