Riff-Raff

From OtakuWiki

Riff-Raff is a character in the manga Gunsmith Cats.

Riff-Raff is a freelance courier, much like Bean Bandit. Also known as "The Snake Charmer", Riff-Raff is about as skilled at driving as Bean, with her greatest ambition to be an even greater courier than him! She often works alongside Bean, although she once punched him in the jaw after making fun of her car, an AC Cobra 427, all because it had an automatic transmission. At times working on the other side of the 'fence' in regart of often taking questionable hires, Riff-Raff also has a strong sense of honor, and would often take care not to betray anyone who has taken confidence with her.

A word of note: Riff-Raff's appearance is similar to that of Luffy, a character in another of Kenichi Sonoda's works from his ARTMIC days, Gall Force. Her short blonde hair with a green streak on it, as well as a tattooed star under her right eye, is the same that Luffy sports.
