Nero is often called Red Saber to distinguish her from other Sabers.She is a blond-haired young girl of short but curvy stature with pale white skin, yellow-ish blond hair with intake and bright lime green eyes. She dresses in a revealing red and white dress with long poofy sleeves, a transparent front, leotard, and knee high golden armored boots. Nero normally ties her long, flowing hair into a complex bun.

Nero had finished organizing the "banquet of the praetor", after achieving victory against Karl, the other version of Charlemagne, and even locking Archimedes for safe measure alongside Tamamo and Nameless, she was smiling widely as she took a rose, staring at her master.

"Oh 'tis such a beautiful night my great praetor, such beautiful night should not be stain my any worries, but, for the sake of dialogue, I , Nero Claudius, the greatest artist and Saber(Red Saber), shall lend my ear to your worries.." Nero smiled fondly not after finishing with her iconic... "Humu humu." as she nodded her head, ever so cheerful.
