Viewers get a glimpse of Vicious and Julia's relationship in the original anime, but the Netflix adaptation offers a more in-depth look at their life as a married couple by showing how abusive Vicious is to Julia. At one point, he chokes Julia after she accuses him of not being "man enough" to stand up for himself.
We also see Julia thinking about leaving Vicious. After her friend Ana tells her to gain control of her own life, Julia shoots and imprisons him.
