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, essentially using two innocent guards to test her newfound powers.

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.

Background
She has been a prisoner for three years prior to her escape.

Jailbreaker Arc
She was a prisoner in the private juvenile hall prior to the start of the Jailbreak competition. She later planned her escape with Aohoshi, head of security of the juvenile hall to switch her with Iizuka, another one of the staff, who was supposed to be the "prisoner" the competitors were supposed to break out. With the jailbreak competition coming, she and Aohoshi managed to modify the security of the facility in order to test the best competitors and get the best hacker in the competition.

Prior to her escape, Kimi somehow managed to attain the "Angel" Dragon that somehow escaped from Kamijou Touma's right hand during the Daihaseisai, but could not use it as it was suppressed by the AIM Jammer in the facility.

Her plans later succeed, when Uiharu Kazari successfully manage to break her out and through hacking alone. Prior to her breaking off her chains and escaping in earnest, Kimi manages to have a conversation with Kazari, where she reveals her method of hacking, amazing Kimi. As the event winds down, she is left alone with two guards. Now that she is out of range of the AIM Jammer, she summons the dragon to eat through her chains and attack the guards to test her new found ability. She later regroups with her accomplices, Aohoshi, Tsurigane, and Raifu, and begin the next phase of the plan, to get the best hacker they know: Uiharu Kazari.

Abilities
Kimi somehow managed to attain the escaped "Angel" Dragon from Touma's right hand, after they came out during the Daihaseisai. Unlike Touma however, she has shown some control of the dragon, and doesn't need to have her right hand ripped off to be used. Here, the dragon is controlled via the right arm and can consume and break physical objects like chains. Kimi likely used the dragon to literally eat the guards that were with her prior to meeting up with her team.
