Misaka 10039

Misaka 10039 (ミサカ10039号) is a Sister, a clone of Misaka Mikoto, that appears in Toaru Majutsu no Index. Originally supposed to be killed in the experiment against Accelerator as part of the Level 6 Shift Project, she is one of the few Sisters that remained in Academy City for readjustments.

Appearance
She looks the same as Mikoto, although for emphasis, her eyes are drawn in a different way. Like all Sisters, Misaka 10039 wears Tokiwadai Middle School's uniform, goggles, and blue-striped panties.

Personality
She has the same personality as most clones, with emotions that have been suppressed as they weren't beneficial to the experiment. Similar to most of the other clones, she seems to have feelings for Kamijou Touma as shown when she displays envy towards the other clones. Later, it is hoped by the Heaven Canceller that she and the other clones will develop their own individual personalities.

Background
Not much is known about her, though as a clone she was most likely produced a few months prior to her introduction in the story.

The morning before Vento of the Front's attack on Academy City, Heaven Canceller is seen talking with the sisters regarding separate measurements for them, Misaka 10032, Misaka 13577, and Misaka 10039 agree that they only need to take one set of measurements since they share the same genes. However, they discover that Misaka 19090 has been dieting in secret, due to Heaven Canceller's suggestion that men, and possibly a certain high school boy, like slender women. Misaka 19090 attempts to get away, but the other clones jump on her. As one of the few remaining clones she was guarding the patients that were evacuated into Hospital buses and taken into the basement of Heaven Canceller's Hospital.

Silent Party Arc
Misaka 10039 was present when the clones received Mikoto's request for assistance in saving Febrie and Janie. They later use the Misaka Network to aid in the calculations on how to launch the Ekaterina II S into space as well as aid Nunotaba Shinobu in giving a calculation boost to the machines Janie is connected on in order to free her, telling Shinobu that they deem Janie and Febrie as their little sisters. After the destruction of the AIM bomb at the hand of Mikoto, they look up to its debris falling towards the Earth.

On September 2 Misaka 10039 is briefly seen enjoying milk tea together with Misaka 10032, Misaka 13577, and Misaka 19090, under the caring eye of Heaven Canceller.

The Fourth Friday of August
In a waiting room in an off limits portion of Heaven Canceller's Hospital called the clinical research area, the 10 Misaka clones having "adjustments" in the hospital come upon a magazine and look up their individual horoscope of their zodiac signs based on their creation dates. Misaka 10039 questions if the information would truly benefit her, confused about its contents, with the others feeling the same about their own individual fortunes.

Finally breaking their confusion of their fortunes, Misaka 10032 wonders what time should they consider to be their birth. She says that the creation dates match the time they are taken from the culture equipment, but they were not taken from the container at exactly 0 years of age, only after they were physically 14 years old through drugs. Misaka 10039 compares it to being inside a mother's womb for 14 years before finally coming out. Misaka 13577 joins in and says that it doesn't matter how long they grew, and says that the time someone comes out of their mother's womb a good enough definition for their birthday. Misaka 19090 protests, saying that the Misakas were taken between various machines while growing, and asks how they should classify it in that case.

Misaka 10032 suggests that the Misaka's date of birth is the day the plan to create them from the DNA map was approved. Misaka 10039 gives a rebuttal however, saying that it would be analogous to the day that the mother and a father decide to have sex. She comments that it would be more like when the sperm was created inside the father's body. Misaka 19090 is shocked by the current direction the conversation is heading. Confused, she recalls that the project to create the Misakas were split into the Radio Noise Project and the Level 6 Shift Project, and asks which of the project's acceptance be taken into consideration. Misaka 10039 suggests that it should be whichever one was the first. Misaka 13577 comments that former wanted a full Level 5 while the latter wanted mass produced experimental subjects, and says that getting a proper definition may be difficult. Here, Misaka 19090 mentions Full Tuning, Misaka 00000, and asks what had happened to her, the clone created by Amai Ao that was cut from the Network.

The girls, tired of their bickering, decided that they did not understand zodiac signs, and decided that they would open up their futures on their own. However, Misaka 10032 adds more fuel to the fire, and shows them a blood type horoscope. The girls who are all Blood-type AB, try to one-up each other who is the superior Type AB as the love fortune of a Blood-type AB is apparently positive to them, leading them to a quarrel.

Later
On the second Friday of October as one of the few remaining clones she was guarding the 7th Level 5 Sogiita Gunha when Ollerus infiltrated Academy City in order to put across a point to Academy City's Board of Directors and Aleister Crowley that if they misuse the Gemstones due to their actions in the Gemstone Mining incident. She was beaten by Ollerus along with the other Sisters.

Toaru Majutsu no Index Movie: Miracle of Endymion
She and the others first appear in the hospital, eavesdropping in the conversation between Touma, Stiyl Magnus, and Tsuchimikado Motoharu, regarding the doom that will befall on earth with Endymion, to which they quickly relay to Last Order.

They later contact Mikoto's friends, who are suprised, regarding on how they will assist them in destroying the explosive bolts. Misaka 10039 holds a Toy Soldier rifle to cover Misaka 10032, who uses a large prototype Railgun to aid Mikoto in destroying the mobile weapons that would've overwhelmed her. As the Endymion begins to break away, she and the others quickly escape the underground base of the Endymion.

Abilities
Like all the Sisters, her ability is known as Radio Noise (欠陥電気（レディオノイズ）), a subset of the Electromaster (電撃使い（エレクトロマスター）) ability. As an esper around level 2-3, the ability allows her to generate 1/20000 of Misaka Mikoto's power, the Railgun, so her ability has a maximum output of only 50000 volts. However, unique to this ability is the Sisters having a form of telepathy that is formed from the similar brainwave patterns, forming a brainwave network. This collection of Sisters connected linked to each other is called the Misaka Network, this also allows her to share memories and experiences with the other clones.

Other abilities

 * Military training: Included in the information that was transferred with the Testament machines, like the other Sisters, she is proficient in combat methods such as the previously mentioned use of specific weapons, being able to trace targets and being able to shake off pursuers.

Equipment

 * Weapons & Gear: She wears a special set of goggles that enables her to see electron beams and magnetic field lines, because like all the Sisters she can't perceive without aid. She also uses a F2000R Toy Soldier and a Metal Eater MX, and is capable using any weapon the other Sisters have used.
