Annerose is a beautiful woman with blue hair and eyes and a slim build.

As a swordsman, she wears dark blue armor with gold accents covering her shoulders and back, paired with black cloth body armor that protects her chest. She also sports a white cape, white armor pants with dark blue accents, gloves, metal boots, and a light green headband adorned with green gems. She always carries her sword.

One day, before the Bushin Festival Tournament, Annerose spots an apparently weak swordsman named Mundane Mann (who is actually Cid Kagenou in disguise). She approaches him, grabs his shoulder and speaks to him in a serious yet genuine tone.

"You’d best give up now. If you don’t, you’ll end up dying in your first battle at the Bushin Festival Tournament."

Annerose Nichtsehen is a powerful wandering swordswoman hailing from the Velgalta Empire, and a former member of the Seven Blades. As a proud swordswoman, Annerose presents herself as cynical and aloof. When she first met Jimina Senen (also known as Mundane Mann, a disguise of Cid), she assumed he lacked skill as a swordsman and condescendingly told him so. Despite her demeanor, she is a good person deep down and will step in to defend others, especially those she unwittingly places in trouble.
