Touko Aozaki

Touko Aozaki (蒼崎橙子) appeared initially as the sister of Aoko Aozaki in the publicly unreleased novel Mahou Tsukai no Yoru and made a later appearance in Kara no Kyoukai. She is also an acquaintance of Alice Kuonji in Mahou Tsukai no Yoru.

A heavy smoker, she is stated to always have a cigarette between her lips. According to her younger sister Aoko, Touko "looks like an educated mom with spectacles and a cigarette".

Role
In Kara no Kyoukai, she is shown as a puppet maker and as an occasional designer of buildings. Together with Mikiya Kokutou, she runs a kind of detective agency Garan no Dou (伽藍の堂) that only engages in cases with supernatural or abnormal elements. She placed a bounded field around the building that houses Garan no Dou that was supposed to make it undetectable via hypnotic suggestions, and made it into her workshop, but Mikiya was able to find it regardless. Because of that, she acknowledged his talent for "finding things" and became his employer.

Touko does not share a particularly good relationship with her sister, yet the causes for this break are unknown. Part of it is probably due to the fact that Aoko, despite being formally inferior magus (not counting her ability to "blow things up"), inherited the title of Family Head of Aozaki Clan. Apparently, Touko is getting money from Mage's Association using her sister's name.

She is also mentioned (albeit unnamed) in the epilogue of Heaven's Feel route of Fate/stay night as a magus on the run from the Mage's Association that made Shirou's "new" body.

Abilities
She's a powerful magus, and she's able to reproduce parts of a body that can be used instead of the lost part. While this would be nothing special, she can reproduce the part in such a perfect way that it comes close to the real one. She is also proficient in using rune-based thaumaturgy. The glasses [[Shiki Tohno ] wears were originally made by Touko. Her sister Aoko stole them from Touko and made them indestructible.

As a doll-maker, she received a Sealing Designation for creating a doll (body) that was an exact replica of her own body.

Touko has 20 Magic Circuits, which was a surprise to the Aozaki clan as the number of Magic Circuits in their line had been dwindling. Due to her formidable power, Mage's Association dubbed her with the color Tou (橙), which is close to the three primary colors. She wished to get the color Blue, but that title was taken by her sister Aoko.

She is able to create a Bounded Field around Shiki's hospital room with the help of a rune stone, which prevents the entry of spirits. One Wraith manages to find his way inside of it by possessing a dead corpse.
