Touko Aozaki

Touko looks like a woman in her late twenties, even when she is decades older. Lord El-Melloi II comments that this is because she is "fixed into place". Despite hating her name due to the association with the color orange, she has a habit of always wearing one orange-coloured accessory.[21] She is a heavy smoker, smoking the rare brand Dragon Smoke despite their bad taste, so she is stated to always have a cigarette between her lips. She often uses them to write her runes in the air Touko originally had a terrible relationship with Aoko because she took her position as the successor to the Fifth Magic.[21] In her later years, however, this relationship appears to be mended. In retaliation for having her prized Mystic Eye Killers stolen from her, she's been making an effort to buy as much stuff as she can under Aoko's name. Even though there's a high chance of her location leaking out if she keeps it up, it seems that revenge against Aoko even takes priority over her own self-preservation.[11]

Touko was originally obsessed with reaching the Swirl of the Root which led her to hate her sister. She was competitive with Araya as they both were trying to reach the Akasha, but eventually she gave up on it. While giving up on it, she enjoys her daily life with people she cares about. She usually cut ties with people and she realized that she stayed too long with Mikiya, Shiki, and Azaka.

Touko is an individual with dual personalities, allowing her to change her personality depending on how she views the situation. She switches depending on her glasses. When wearing them, her facial expressions are calm and kind and she is objective and ruthless. After taking them off, her facial expressions are very cruel and she is subjective and emotional She hates being called "Scarred Red" as it reminds her that although she wanted the colored title of Blue similar to her family name, she instead ended up with the colored title of Red. The nickname implies that her given name of "orange" is merely a tainted color of her title of red, a pure primary color. She made a personal rule that whomever calls her that nickname would end up with a death sentence
