**Misaka 13577** (ミサカ一三五七七号, *Misaka Ichiman Sanzen Gohyaku Nanajūnana-gō*?) 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 13577 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.

## Chronology

### Toaru Majutsu no Index

#### Academy City Invasion Arc

*Main article: Academy City Invasion Arc*
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.

### Toaru Kagaku no Railgun

#### Silent Party Arc

*Main article: Silent Party Arc*
Misaka 13577 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 13577 is briefly seen enjoying milk tea together with Misaka 10032, Misaka 10039, and Misaka 19090, under the caring eye of Heaven Canceller.

## Abilities

Like all the Sisters, her ability is known as **Radio Noise** (欠陥電気（レディオノイズ）, *Kekkan Denki (Redio Noizu)*?, lit. "Flawed Electricity"), a subset of the **Electromaster** (電撃使い（エレクトロマスター）, *Dengeki Tsukai (Erekutoro Masutā)*?, lit. "Electricity User") 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 aforementioned use of specific weapons, can track targets, and shake off pursuers.

### Equipment

* **Weapons & Gear**: She wears a special set of goggles that enables her to see electron beams and magnetic field lines, which like all the Sisters she cannot 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.
