Jennifer

Jennifer is a rather sexy woman (much to Laharl's dismay) and often jokes around in a very flirtatious manner. In the anime, her breasts would often bounce whenever Laharl would take notice. She was also afraid of the Netherworld once, thinking that demons were nothing but monsters that would hurt innocent people, especially women and children, until she saw the child-like appearances of Laharl and Etna. Despite her appearance, however, her intelligence and technical knowledge surpasses most scientists. In fact, she was the one who created the All-Purpose Robot Thursday at age five and even earned her Ph. D at age ten. She is also skilled at martial arts, specifically kung fu - a skill now extinct on earth. Of all the characters in the game, she is the one who supports Gordon the most.
