|Japanese name:||神楽崎 雅|
Although the impression is given that she is a tough-as-nails workaholic, she shows various signs of being a very deeply compassionate person. When the pet ferret was in danger of dying from being crushed by a gigantic heirloom pendulum clock, for all her initial dislike of the animal she raced to find a crowbar which she then used to free the ferret, which later became more attached to her than to Tina. Aoi later explains that the ferret could sense the kindheartedness within Miyabi's samurai-like demeanor.
In the manga, it's revealed that her parents worked for the Sakuraba family before they passed away from an accident. Aoi's mother then took in the orphaned Miyabi, who then was tasked with caring for Aoi. She has great respect for Aoi, and shows this by adding the honorific "-sama" after her name. After accepting Kaoru, she adds the honorific "-dono" after his name.
Her given name means "refinement," which befits her role of training Aoi to be a good wife.
