Kanzaki Kaori

An eighteen-year-old magician from Necessarius. Unlike her partner Stiyl, she uses magic to magically strengthen her body. Her sorcery name is Salvare000, "The one being saved becomes the hand that saves".

Appareance
She has long black hair tied up in a ponytail. She also wears a pair of jeans with one side that's shorter than the other side. She uses a two-meter-long nodachi called "Seven Heavens Seven Swords" as her weapon. She has a special attack called Nanasen that uses her sword and some wires.

Personality
She used to be a kind woman who treated Index like a sister, but when Index's memories were deleted by Necessarius, Kaori changed into a cold and silent woman as Index no longer remembered her and consequentially did not trust her.

Background
First time in the novels, she shown as an antagonist who fights Touma and defeted him, later she tell the reason why they doing this. Later in the novels, more of her past is revealed. Not only is Kaori a skilled swordsman, but she is a Catholic Saint possessing the "Stigma", the ability to call upon God's power and the former leader of the Amakusa Catholics; however, Kaori left the group as she resented that she had been fated since birth to become its leader, which led her to despise the concept of luck and fortune as her fortune in turn only bring misery to those around her from what she can see, as it has been mentioned in the novels she no longer wants to see innocent people rushing to protect her, dying in the process, and saying with their last breath that it's alright as long as she's fine. Although she is Catholic, she joined Necessarius as it's a group which even her fortune won't rob them of their lives and befriended Index, developing a sisterly relationship with her. The repeated failed attempts to make Index remember her after each memory erasure resulted in her cold personality as Kaori began to accept that no matter how much a person tries, no one can change their destiny. She begins to show a kinder side to herself after Tōma saves Index and gradually falls in love with him after he helps her face her past with the Amakusa Catholics, becoming more prone to showing emotion and sometimes showing a little embarrassment if she is with him, though many of them are awkward interactions from her trying to thank Touma for saving the members of the Amakusa Church on various occasions and Tsuchimikado Motoharu's attempts to encourage Kaori into various cosplay gear.

In her fight against Aqua, realized she was as arrogant as Aqua. She brushed off Amakusas thinking they're weaker than her, that they need to be under her care at all time so for the first time she asks Amakusas to help her fight Aqua.When Aqua scoffs at Kanzaki saying if she values her life that much, but to this she replies she's only hurt them by leaving them because she was looking down on them as well. Now she will gain her place back and believe in them instead of blaming them and at the end of light novel, she confused how she thank Touma, Tsuchimikado says to her that this is the only way to pay her debt back to Touma is by wearing a fallen angel maid costume. Kanzaki in state of confusion tell Tsuchimikado to bring the costume and ten minutes later she enters Touma's room and then the "fallen angel accident" happened.

Trivia

 * Some of the 'cosplays' Motoharu suggested are maids, angels, fallen angels and/or ero versions of one or more of them, which later on making "fallen angel accident" at the end of the Volume 16.
 * From the SS light novel (also known as volume 13.5), from what Tatemiya Saiji said to decline the Captain of the Knights of England invitation to a ball "You can go home. Our priestess likes to lead a young man rather than being led by an older gentleman", it's now became a rumour that spread across half of London that Kaori has a crush on Kamijou Touma, which doesn't seem to be false from their various interactions between the two. Even people like Laura Stuart makes fun of Kaori using this rumour.
