Shundan Kimi

Kimi (嬉美) is a character introduced in Toaru Kagaku no Railgun. Initially a prisoner in private juvenile hall, she was freed after her allies took advantage of the jailbreak trial to break her out.

Appearance
Kimi is a young woman with long light colored wavy hair, which covers the left side of her face. She has notably sharp teeth.

Personality
She has a vicious personality, using two innocent guards to test her newfound powers. However, she seems to be kind to her subordinates, being willing to let them do what they want once they finish a job.

She is a fan of the musical group Mariophanie and is shown to be both singing and listening to their songs, though she dislikes the material they've released after her escape.

Kimi appears to be apathetic to her surroundings. She paid little attention to the conversations of other prisoners to the point of being unaware that there are now seven Level 5 espers.

Background
She had been a prisoner for three years prior to her escape. At some point, Kimi seemingly managed to attain the "Angel" Dragon that somehow escaped from Kamijou Touma's right hand during the events of the Daihaseisai, but could not use it due to the effects of the AIM Jammer in the facility. Kimi was able to contact her ally Aohoshi, who had infiltrated the juvenile hall staff as head of security. Kimi told Aohoshi about how she had managed to obtain the dragon, though Aohoshi was incredulous at this.

Jailbreaker Arc
She was a prisoner in the private juvenile hall prior to the start of the Jailbreak competition, in room 42. When the jailbreak trial was devised, her allies took advantage of the opportunity to engineer her escape, including Aohoshi. She was to be switched with Iizuka, one of the jailers who was playing the "prisoner" which the competitors were supposed to break out. With the jailbreak trial coming, she and Aohoshi managed to modify the security of the facility in order to test the best competitors and find the best hacker in the competition.

The plan ultimately succeeded, when Uiharu Kazari successfully managed to break her out and through hacking alone. Prior to her breaking off her chains and escaping in earnest, Kimi managed to have a conversation with Uiharu, where she revealed her method of hacking, amazing Kimi. As the event wound down, she was left alone with two guards. Now out of the AIM Jammer's range, she summoned the dragon to eat through her chains and attacked the guards to test her newfound ability. She later regrouped with her accomplices, Aohoshi, Tsurigane, and Raifu, and began the next phase of their plan, to get the best hacker they know: Uiharu Kazari.

Kimi played a card game with Tsurigane and Raifu. Aohoshi revealed that she has obtained Uiharu's registration data. Raifu commented on how Uiharu was with the Railgun, which surprised Kimi when she is informed that the Railgun is the third-ranked Level 5, and there are now seven Level 5s in the city since she was incarcerated. Aohoshi remarked that the information regarding the Level 5s should have been passed around by prisoners to which Kimi revealed that she simply wasn't interested. Aohoshi said that the city's strongest espers are claimed to rival a navy cruiser's in firepower, thought Kimi seemed unimpressed, as she won the card game.

Later on, Kimi's group manages to abduct Uiharu. They take her away in a recreational vehicle (RV), driven by their female minions. Kimi apologises to said minions, saying that neither she nor her friends can drive, and tells them that they can go wherever they want after the job is over. The RV is attacked and stopped by Mikoto and Kuroko, the former ordering the minions to release Uiharu. Kimi tells the minions to ignore Mikoto and go, then greets Mikoto as the Railgun. She tells her that she only wants Uiharu to do a quick job and will return her unharmed afterwards, which Mikoto does not accept. Kimi unleashes her dragon, unsettling Mikoto as she recognises it as the one that emerged from Touma previously. Mikoto attacks with iron sand and demands to know why she has it, but Kimi replies that she doesn't know. The dragon transforms the iron sand into a white substance that easily crumbles, and then destroys a building with its charge. Raifu asks if Kimi got Mikoto, but Kimi denies this as Mikoto wouldn't go down that easily. Kimi and her group flee in two vehicles, using the entrance-way road that leads to School District 11.

Abilities
Kimi appears to have somehow obtained the escaped "Angel" Dragon from Kamijou Touma's right hand, which was unleashed during the events of the Daihaseisai. Unlike Touma however, she has shown some control of the dragon and doesn't need to have her right hand ripped off in order to use it. Here, the dragon is controlled via the right arm and can consume and break physical objects like chains. It is strong enough to destroy a building with its charge. It also has the ability to transform iron sand, and possibly other substances, into a white substance that crumbles easily (implied to be salt, from Raifu's reaction). This ability causes a cross on the dragon's head to light up, and leaves a similar cross mark on whatever is transformed.

The effects of AIM Jammers prevent Kimi from making use of the dragon.
