Carrera assumes the appearance of a young woman with shoulder-length blonde hair and blue eyes. She wears a black snow coat with a skull pin over a white shirt and tie. Her appearance gives off the vibe of a high school delinquent. She is slightly taller than Ultima but shorter than Testarossa. She is carefree, energetic, and exhibits a love for engaging in battles, often unleashing her Nuclear magic for sheer enjoyment. Additionally, she tends to be egocentric and has a tendency to become easily angered. Devoted to Rimuru and Ryushen

Ultima takes the appearance of a cute and beautiful girl. She has middle length purple hair tied into a side ponytail, as well as purple fingernails.
