J is best described as a "lethal workaholic", as she is incredibly dedicated to her job. She also uses corporate jargon like "synergistic liability" and "fourth quarter profits" as insults or vulgarism. Although J is not as sadistic and insane as V is, she does look down on others who are not as good as her. This is best shown in J's relationship with N, as she despises him and tells him that she would personally kill him if their company allowed it.
