J is best described as a "lethal workaholic", given that she is incredibly dedicated to her job. Although J is not as sadistic and insane as V is, she does look down on others who are not as good at their designated task. This is best shown in J's relationship with N, as she despises him and tells him that she would kill him if their company allowed it. J's dislike of N goes as far as to infect him with a virus as soon as he starts to question the company (loves TW0K1DD0)
