Aoko Aozaki

Height: 163 cm (Mahoutsukai no Yoru)

She is described to be an extremely strong person in terms of personality, regretting nothing in her life because she follows through on every decision she makes. Because she does not care at all about what other people think of her, she is able to stay true to herself in any situation, believing that the worst thing a person can do is to lie to oneself. Even while accepting her life as a magus, she stubbornly sticks to the life of an honest person. Although people know her as "Magic Gunner" or "Miss Blue" and fear her power, her actual magic is a mystery. She also has a sister, Touko Aozaki, that appears in the parallel story of Tsukihime, Kara no Kyoukai. Despite the fact that she and Touko are sisters, Aoko shows great hostility towards her, to the point that she dislikes Touko's form of Thaumaturgy.

During Tsukihime (月姫): A wandering Magus Shiki Tohno met in his childhood years. At the time, Shiki was still under hospital care and recovering from the accident that caused him to see lines that no one else could, which gave him his Mystic Eyes of Death Perception that he didn't know how to use properly. It was she who gave him a special pair of glasses, the Mystic Eye Killers, that block the lines from his vision. However, the biggest gift she gave him was the meaning and will to live his life. Since she doesn't like her name as it sounds like Blue Blue (Ao = Blue, __Ao__ko __Ao__zaki), Shiki decides to call her "Sensei" (Teacher). Shiki has never referred to anyone else in his life as such; that's how much he respects her.

During Mahoutsukai no Yoru (魔法使いの夜): A 17-year-old apprentice magus learning Magecraft from Alice Kuonji in Misaki Town. Aoko tries to live two completely different lifestyles, as a normal high school student during the day and acting as a Magus during the night, but Alice reprimands this as a half-hearted approach.

~!Aoko is a Magician capable of utilizing the Fifth Magic (第五魔法), making her the only person in the current world capable of performing its miracles. The Fifth Magic causes Aoko to go into a Redshift (赤方偏移) state, where her appearance and age are slightly changed, and her hair is turned red. Its exact domain is uncertain, but it has roots in time travel. Her usage of it is limited to localized individual time travel, but Touko, her sister, cannot believe that is the true nature of the Magic. The concept of time travel falls under the Second Magic, so it makes no sense for such an ability to now be called the Fifth Magic, but Touko decides further speculation is none of her business. Despite Touko being a vastly superior magus, Aoko was chosen to inherit the Magic instead of her. It also holds the answer as to why she is called the "newest" Magician. She is familiar with Zelretch and the Second Magic to some extent, as she is able to classify Neco-Arc existing in the world of Melty Blood as his doing.!~
