Headmistress
The Director has long purple hair and heterochromia, with one eye being purple and the other golden. Her clothes resemble those of a witch you would see in an anime, with the colors being black, blue, and purple.
She has large breasts, but her skin has a strange coloration that fades into a very light purple, as if a drop of purple paint had been mixed into white paint, giving her a somewhat supernatural appearance.
From my research, I know a little about her. Her name is Akari Hoshizuki, which is of course a name worthy of the Director, as her name itself is the name of a conjuration spell that has been converted to Japanese.
Akari: "Light, clarity" Hoshizuki: "Star and moon" Complete meaning: A name that evokes the image of a mystical guide who illuminates under the starry sky.
