Aoko Aozaki

Aoko Aozaki is a heroine from the Nasuverse who is also known as Miss Blue and Teacher and is a magician.

Background
Aoko is a member of the Aozaki family, the current Family Head of the clan. She has a very bad relationship with her sister, Touko Aozaki, who often steals money from the Mage's Association by using Aoko's name.

Personality
She is shown to have a bright cheerful personality that reacts very strongly to careless actions. But, as a teenager in Mahoyo, Aoko shows an aggressive personality at the beginning until she develops some care towards the others beyond Alice, such as when she and Soujuurou become friends.

Despite the fact that she and Touko are sisters, Aoko shows great hostility towards her, to the point that she dislikes Runes because Touko use a Rune-based Thaumaturgy. However, she is considered irresponsible by Touko for using the power of Magic without thinking about the consequences.

Aoko values special places with precious memories and living things, regardless of if they are humans, animals or even plants; to the point where she used the Fifth Magic against Touko just after the temporary death of Soujuurou. She has passed on the "value of life" to Shiki Tohno.

She doesn't like her name because it sounds like Blue, so Shiki decides to call her "Teacher".

Appearance
Aoko shows a very beautiful physical appearance with a white skin and the combination of brown hair with blue eyes. Usually she uses at home a light blue sweatshirt and gray jeans or a casual-red dress with an under-black shirt and pants with a pair of boots. While out, she often uses her school uniform or her brown coat with an chess style of scarf on her neck over the uniform.

Just after she fast-forwarded her own time, Aoko appeared with her red hair, wearing a white shirt, blue jeans with pulled at the knees and a pair of brown shoes.
