J is best described as a "lethal workaholic", given that she is incredibly dedicated to her job, although she is not as sadistic and insane as V is. She looks down on others who are not as good at their designated task. This is best shown with her relationship with Any, as she despises him and tells The that she would kill You if their company allowed it. Her dislike of U goes as far as to infect you with a virus when learning that Yo wants to rebel against their company and what they stand for.
