Fräulein Kreutune

Fraulein Kreutune (フロイライン＝クロイトゥーネ) is a character introduced in Shinayaku Toaru Majutsu no Index.

She is a mysterious, seemingly human, woman who has existed since the age of witch hunts, and by the time of the Ichihanaran Festival Arc, was imprisoned inside the Windowless Building until being freed through the efforts of Kamijou Touma and Thor.

Etymology
Fraulein is derived from the Germanic honorific that is previously in common use for unmarried woman, comparable to Miss in English. It can be presumed that Fraulein isn't actually her name, as even Reading Thoth 78 has declared that her identity is unknown.

Appearance
Kreutune has the appearance of a woman who is almost two meters tall. She has silver hair, which is depicted as lavender in the illustrations instead of Index's "blue" silver hair. Moreover, the hair is unkempt and is long enough to reach her ankles and obscure her face. Her clothes consist of a two-piece transparent dress made out of synthetic fiber, revealing her pink underwear.

She is seen by Touma as having inhuman characteristics, despite no obvious signs of being different from a regular human being, just a feeling of something singularly off regarding her appearance, most likely similar to the Uncanny valley.

Personality
Fraulein has no readily apparent personality, other than her seemingly infinite curiousity to absorb information. She has no concept of like or dislike, and she is driven not by any sense of ideology but by curiosity. It's as if her entire existence is based solely on her absorbing information or learning as much as she can from her environment, as concluded by Reading Thoth 78.

She is apparently not particularly malevolent and only attacks when provoked, or if she deems certain people as threats such as Thor or Kamijou Touma. Moreover, she's benign enough to be strung along by two children, specifically, Last Order and Fremea Seivelun. Furthermore, she is utterly taciturn, only speaking when asked, as with the case of her telling Last Order and Fremea Seivelun who she is.

Background
Records of her existence in the pasts, specifically those in the age of witch hunts in the Middle Ages, shows that she wasn't as taciturn as she was now. The veracity of these reports is unknown, but it shows that Fraulein can full meaningful conversations with others, and can do sarcasm and even boast. It is the case with one of her trials, were a person she calls a priest "kind" to mock him of his actions towards her, which did no work due to her queer abilities. Moreover, she apparently had normal human emotions and expressions.

She seems to be immortal, impervious to conventional forms of damage, and retains her youthfulness. Legends abound that she has survived and outlasted 308 of the trials by ordeal that became the basis fir the "confession by torture" method that was later often used in witch hunts. Although accounts of her do exists, they are buried by numerous other legends during the time period of the witch hunts. Because she is an impedement to the Plan related to Academy City, due to her innate drive to learn and transform after acquiring enough information, she was imprisoned the formerly impenetrable Windowless Building, the same building where Aleister resides in. In total silence and darkness, this sensory deprivation prevents her from being curious.

Baggage City Arc

Othinus first mentions Fraulein at the end of the suppression of Baggage City by Academy City, where Fraulein is apparently part of her goal to gain power through the distortion of the world—holism.

Ichihanaran Festival Arc

Eve of the Festival
Fraulein is mentioned several times by Thor, and uses the fact that she is trapped inside the Windowless Building to recruit Touma into rescuing her as she is the center of Othinus and Ollerus conflict that may put Academy City in danger. However, she first appears only after Thor and Touma break through Calculate Fortress, and from there, piques the attention of Fraulein, and creates a huge hole from which she emerges. She immediately notices Touma and Thor, and quickly subdues them via her powers, and from then on, the City went into Code Red.

Fraulein reappears after destroying the Four Wings that threatened Thor and Touma a while back during their attempt at breaking the Calculate Fortress, near a takoyaki stand that was preparing for the Ichihanaransai, and in her curiosity, first stares at the man working on it and then starts imitating him, as if she herself was making the takoyaki. At first she was clumsy at it but became more adept quickly. As she does that, several Anti-Skill operatives led by Kakita appear before her. As he reports to his colleague over the radio that he and his unit will now restrain her, but is apparently told over radio that they have no jurisdiction. Kakita argues with someone over the radio, after being told that they should take Fraulein to a place which has the jurisdiction. Kakita tries to argue his place, and states that the standard procedure is to take her to the neares branch. He is then told a false report that Fraulein is a spy disguised as a diplomat, but this does not make Kakita yield. He later orders Momozawa to handcuff her, and Yashiro to bring the Anti-Skill truck around. However, before Kakita can finish his instructions, Fraulein stood up and they are forced to surround her. Fraulein gets away and can be assumed to have taken them out herself.

As Last Order and Fremea Seivelun continue to there lost sojourn in Academy after eating at the Food Stand Spire, the two girls discover Fraulein, who begins to mimic Fremea's movements. For some unfathomable reason, Fraulein aids them in finding their way back into School District 7, and is successful, as Last Order recognizes an area. After being dragged along, Last Order tries to thank and her and asks her name, to which she responds that her name is Fraulein Kreutune. Last Order and Fremea wants to exchange e-mail addresses with her, but seeing as she had no cellphone, Fremea however, gave Fraulein her child buzzer to her that was originally from Hamazura Shiage and the others. Fremea tekks her that it uses GPS, and if she pulls the string, it will send her current location to the cell phone registered with it. Essentially, allowing Fremea to be notified of her whereabouts. Fremea notes that it can receive e-mails without cost from the registered cell phone. Fraulein seemed puzzled with the device, and continues to stare at it. She is interrupted by Last Order saying that they are now friends. Fraulein is confused by this, to which Fremea answers that there is no reason why they can't be friends. After analyzing the situation, Fraulein concludes that they are indeed friends.

While Fraulein ponders to herself what the term "friends," Anti-Skill surround her and uses anti-life form and anti-machine smoke bombs. The narration refers to having her eyes roll in a strange way that seemed odd for a response to violence.

As the eve closes down, Reading Thoth 78 discusses with Aleister Crowley, who apparently accessed the AI, regarding Fraulein Kreutune. It states that Fraulein will transform after acquring enough information, though states that it will take 2,300 years for her to collect such information. However, if she consumes Last Order's brain and takes control of the Misaka Network, she can reduce 2,300 years to a mere 3 seconds. The AI notes that the time when Fraulein will acquire the properties that is needed for her to absorb powers through brain consumptions is within two hours.

General characteristics
Fraulein is a queer existence. According to Reading Thoth 78. despite some genetic differences, Fraulein can only be called human, therefore, she could either be another species of human or a subspecies of it. However, it concludes that her identity, probably including what she truly is unknown. To add further proof to this, she is referred to by the AI as a life form that does not possess a Personal Reality as she does not have a mind or ego, a prerequisite for humans to be referred to as espers, and that her powers project only from her simplistic mind in contrast to espers who control it through the use of their entire body and is corroborated by Thor referring to her as a person that has not been dyed by the colors of "magic" or "science."

Information absorption
Her thought patterns are referred to as similar or even more simplified compared to an insect, but her body is overly optimized. Her only apparent motivation is to "learn". She scans the conditions of her environment and the direction that leads to the most suitable environment for her, and here, regardless of what type of information, she absorbs the information in her environment by scanning it. This ranges from apparently simple observation, to plain mimicry, as with the case of the boy in the takoyaki stand, which she starts imitating, eventually becoming even better at it. Continuing with the insect metaphor, once Fraulein has absorbed enough information, she will grow from a collection of continuous thought processes even simpler than an insect’s to a more complex and flexible thought process. In the process of that growth, she will likely experience a great change, that is probably greater to what can be referred to as "Fraulein Kreutune". Fraulein has the ability to modify herself to adapt herself in the environment. Since, she has physical limitations, her transformation will only occur after she has absorbed enough information which should take her an estimated 2,300 years. However, with the advent of the Misaka Network, if ever she can control it after eating Last Order's brain and reproduce its structure within herself to acquire its properties, she can reduced the time to three seconds. Furtheremore, if she deems doing so is necessary, any personal circumstances, such as her friendship with Last Order, are estimated to not be enough of a factor to stop her true nature from taking over and eating the brain.

Once transformed a great change between a larva and an adult insect, that is Fraulein Kreutune, which her transformation conceals the possibility of reversing the position of prey and predator. If the position of the hunter and the hunted are reversed, the construction of the food chain will collapse and incredible damage will be done to the current culture that is centered on mankind’s use of science. The deprivation of her senses, and putting her in an environment that she does not consider interesting stops her from learning anything and potentially "transforming."

Other abilities

 * Immortality and Agelessness: Fraulein is seemingly immortal and has lived for hundreds of years if the records of her existence are to be held true. Moreover, if she is indeed hundreds of years old, she retains the look of an adult woman, giving her the ability to retain her youth.
 * Invulnerability: According to medieval records, no form of torture and trial, such as burning, crushing, and drowning, was not able to harm or kill her. This unique durability of hers and her characteristic of being neither a magician or an esper, is what attracted Othinus to her for her plans as she can survive any modification she will put her through. Although she is invulnerable to conventional methods, people such as Othinus and Ollerus maybe able to find a way to harm her.
 * Microscopic substance insertion: It is the name Thor uses to refer to Fraulein's ability that she used on them and on the Calculate Fortress. She somehow inserts a microscopic substance inside the target, which immediately affects it. If the target is organic, it will cause it to faint, due to the effects that exhibit characteristics similar to an organ transplant rejection. If the target is inorganic however, the substance expands from within, tearing it apart. Thor states that he has no idea of the fundamental issue of what she is controlling, while Touma conjectures that it may be related to her durability and immortality.

Character Art Designs
Fraulein is designed as she is described in the novels. Not much else is known about her design details, but Haimura comments on how she reminded him of the Pillar Men of Jojo's Bizzare Adventure fame.
