Cendrillon

Cendrillon (サンドリヨン) is a character introduced in Shinyaku Toaru Majutsu no Index. She is a magician once affiliated with GREMLIN and is the first human magician (unlike Mjölnir) from their group to be introduced in the story.

Etymology
Cendrillon is a name that is derived from the French version of Cinderella.

Appearance
Her nationality and language is French. She has blonde hair and white skin. Her body is slender, beautiful, and she had a well-featured face. Her dress gave an image of an ideal girl from a picture book looked like a princess. The dress is made of countless thin membranes placed one on top of another with her body lines clearly visible (compare with Carissa). The only thing out of appearance was figure-correcting underwear binding to her entire body; it seemed like a diving suit that lay at the core of her elegant dress.

After being saved by Ollerus, she has now the ability to reconstruct her body via having someone use the proper amounts of ingredients. However, if the one that is going to reconstruct her gets the amount incorrectly, strange results can happen, for example, like what happened with Mugino Shizuri, where Cendrillon, though alive and well, was in the form of a young girl.

Background
Her real name and other personal information is unknown, though since she speaks French and the fact that she uses the French name for Cinderella, it can be assumed that she is French, and that she only changed her name into Cendrillon in order to make her Cinderella-based magic more effective, via Idol Theory.

Hawaii Invasion Arc

 * Main article: Hawaii Invasion Arc

When Leivinia Birdway activated her plan to draw out GREMLIN magicians by setting up a bomb, Cendrillon was sent to stop the bomb, since GREMLIN was an ideological organization, not knowing that it was a trap set-up by her. During the battle, she uses her Cinderall-based magic against Leivinia's guards, and later showed her knowledge on Kamijou Touma by using him against Hamazura Shiage and Misaka Mikoto's attacks during his attempts to stall for time until Leivinia.

Her domination however, was short-lived, as before she can perform a spell after noticing Accelerator, Leivinia attacks using an jet fuel tanker to keep her down up until Leivina can use the one weakness of her magic. Using Idol Theory, she mimics the arrival of dawn using the explosion of the tanker, weakening her, and releasing the spell on Leivinia's subordinates. She is later caught for interrogation.

During the interrogation by Leivinia and Accelerator, a superior of Cendrillon contacts her, forcing Leivinia's hands into violence, which resulted in breaking her wand, and seriously injuring Cendrillon. Expecting the superior to aid her, she is later surprised as the superior forces her using a spell to drive the part of Leivinia's wand that have been broken into her temple. She later falls to the ground, bleeding severely. Leivinia notes that what she has done may have caused a subarachnoid hemorrhage to her brain, and would not allow them to extract information from her anymore. Leivinia later notes that she needs only to reel GREMLIN, due that the fact that they contacted them in order to silence Cendrillon.

Cendrillon is later discovered to have survived, and is being heavily guarded by American forces along with Saronia A. Irivika, the colleague who forced her to stab herself. However, she later escapes at the onset of the invasion without anyone knowing at all, and confronts Marian Slingeneyer, the smither and creator of Mjölnir, and one of the true members of GREMLIN. Here, she reveals to Cendrillon the true nature of the invasion, as the eruption was the only event they wanted to happen. Angry at the fact that she was used and the fact that the invasion a lie, Cendrillon attacks but is quickly struck down. She is later asked by Dverger what form she would like to her to make into.

Baggage City Arc

 * Main article:Baggage City Arc

Cendrillon reappears while Marian communicates with Sigyn. As Marian Slingeneyer promised, Cendrillon is alive but is in a form of a table. Here, she is being kept in a secret room made by Marian near Baggage City's waste disposal facility.

After the battle between Othinus against Ollerus and Fiamma, Touma still wanted to help those in need despite needing rest himself. Ollerus told him that with the intellect of him and Fiamma and his eventually recovered right hand, the soldiers who were turned into pillars, Cendrillon, and others made into furniture could return to normal.

Eve of the Festival

 * Main article:Ichihanaran Festival Arc

Ollerus turned Cendrillon back into a human and is now able to reconstruct herself. She swears vengeance on GREMLIN and tries to contact the group that opposed them in Hawaii. She somehow sneaks into Academy City via putting the ingredients and tools for her reconstruction into a package and mails it to Mugino Shizuri. Although, she was most likely trying to get into contact with Shiage, who was part of the group in Hawaii.

Regardless, Shizuri acquires the package, and part of her readjustments of her new prosthetics was to carry out moderate excercises with the parts. After following the instructions carefully, she successfully "cooks up" Cendrillon. She introduces herself to Shizuri and tells her of her goals. She then asks Shizuri to make her Cinderalla dress, at which point she has exhausted Shizuri's patience after she states that whatever Shizuri is doing looks like good training for a wife, who proceeds to attack her with her Particle-Function Waveform High Speed Cannon, destroying a part of the apartment she and the rest of ITEM are staying in. Cendrillon escapes with only a towel and the instructions for sewing her dress on her person.

Cendrillon later successfully sneaks into one of the schools and sews herself the Cinderella dress. She ponders on how Touma is being used by several people through the use of edited information in for them to use his right arm. She then makes up her mind that she will follow Touma in order to achieve her goal in getting revenge against GREMLIN.

Cinderella-based magic
As Birdway explained Cendrillon used magic transformed the story of Cinderella into an attack spell by overwriting religious motifs into it using the symbolism of the dress she wears. For example, in the tale, by using the fact that an amateur girl was given dancing skills for a ball, Cendrillon could move at high speeds fast enough to casually avoid a cluster bomb dropped near her. Her combat skills were also developed to be countermeasures to Kamijou Touma's Imagine Breaker since he can't hit fast enough.


 * Cinderella Attack Spell - Using her foot size of 22.5 cm, any feet smaller than hers will have their bones forcibly widened and if any feet are larger, toes would be severed.
 * High Speed Movement - Cendrillon grants the ability to move quickly based on the concept of the pumpkin carriage that brought Cinderella to the castle.

Other abilities

 * Body Reconstruction - After being turned into a table and then returned into a human by Ollerus, Cendrillon gained the ability to somehow separate herself into small parts and apparently remain alive. Those same parts are the "ingredients" that are used for her body reconstruction, though, requiring someone to follow the instructions to the letter.

Speculation
Cendrillon is the first magician to have Accelerator contemplate whether or not could his vector manipulation affect or defend against magic. He stated that if it was an attack that was area based or moving along surfaces he would be fine, but if the spell was like cursed straw doll ignoring any distance he would be in trouble.

Weaknesses
Birdway, however, demonstrates the inherent flaw to Cendrillon's spells: the concept of midnight, the same time when the magic placed on Cinderella by her Fairy Godmother wore off. The conditions of midnight like "sunrise" and "a clock that strikes twelve" is enough to render Cendrillon unable to use her abilities, and the conditions can be easily simulated by intense light or manipulating clocks to show 12:00 respectively.

Design evolution
Haimura designed her to look like she was wearing a futuristic spacesuit, and draws inspiration from Kamen Rider Fourze
