Jean Arnoul, known as simply Jean-Paul in the English dub, is the older brother of Francoise/003. In this adaptation of the series, he worked as a stunt pilot rather than being in the Air Force.
Jean's character design seems to be modeled after his initial manga appearance, although depicting him somewhat older. He seems to be in his mid-to-late twenties and has blonde hair, with fringe covering one of his eyes.
Francoise first refers to Jean as having been very protective of her when they were children, with him fighting off bullies that had been harassing her.
