High pitched, childish laughter trilled through the air, preceding the girl who would undoubtedly follow. As could be expected by any regulars around 99th street, a small, thin body came flying out of an alleyway at top-speed, arms flailing wildly to signal people to move out of the way. "Pedestrian crossing! Move it or lose it!" she yelled, as people parted to let the crazy Rudie through. It wasn't necessary. Leaping nimbly off a rail, Nana easily cleared the throng of people and continued down the street. "Sorry people!" she called back, before jumping to grind another rail. Her energy couldn't be matched by...anyone, really.
