Aurelio appears to be stoic and detached even somewhat robotic, according to Niya. However, it turns out that his seriousness is a mask that covers his more dynamic personality. Unlike his sister and mother, he is much kinder and more open to others as seen when he brings enough candy for everyone to share with. In terms of social life, he appears to be socially lacking as he does not grasp puns and jokes. He also does not understand movie references as he has never watched movies before.
