Kouzaku Mitori

Kouzaku Mitori (警策看取) nicknamed as Mi-chan (みーちゃん) is an antagonist in the Toaru Kagaku no Railgun Manga. She is a mysterious girl who works under the orders of Kihara Gensei and is currently targeting Misaka Mikoto's Sisters.

Appearance
Mitori is a girl of roughly Mikoto's age, with dark-colored hair styled into twin tails and dark-colored eyes. Her outfit resembles a dark-colored nurse's uniform modified to contain elements of punk fashion, particularly skull-themed accessories. She also wears a pair of dark-colored hosiery and matching pumps. Occasionally she can be seen wearing a hood that conceals much of her outfit, and an accessory she often keeps with her is a short whip called a riding crop.

When she was younger she wore her hair short, and that fell down on both sides of her head.

Personality
Despite belonging to the dark side of Academy City, Mitori possesses a rather cheerful personality and a tendency to find time to be happy despite of her exposure to sinister environments, which is a testament to her sizable experience in the dark side. In fact, she considers those who are able to live peaceful lives in Academy City as "oddities".

Background
When she was young, she was a test subject of the Clone Dolly project, the same facility where research in the Exterior Project was being conducted. There she met and began to visit Dolly everyday and with played with her as friends, using her powers on a bottle of liquid metal to turn the metal into shapes. Supposedly one fateful day she came in as a check-up on Dolly was being conducted and apparently, according to Dolly's explanation, was horrified after seeing the extensive life-support machines that were embedded into her body to keep her alive. She never visited Dolly again, which made her depressed to the point that the researchers there asked Shokuhou Misaki to use her powers on Dolly to make her think she was her friend Mi-chan. Much of this story, from the researchers, is questionable at best and it later motivated her to seek revenge on Academy City for her.

Mitori later attended Kirigaoka Girls' Academy Middle School and later performed a terrorist attack on the Academy City Chairman of the Board but failed in doing so. 14 months prior to the Daihaseisai, as Kouzaku Mitori was put in the Reformatory (Juvenile Hall) for the the terrorist attack. She is later busted out by Kihara Gensei, becoming part of the Dark Side of Academy City. Presumably, because Mitori is part of the Dark Side, she does not have a wanted notification even though she escaped from the Reformatory. Based on data that Shirai Kuroko and Uiharu Kazari uncovered, Mitori would be a 3rd year student in Kirigaoka Girls' Academy Middle School at the time of the Daihaseisai if she hadn't been involved in the "terrorist attack" incident.

After her escape she is promptly declared dead, working for Kihara Gensei and infiltrated MEMBER for him, the latter as a middleman between MEMBER and the Academy City Board of Directors.

Daihasei Festival Arc
Kouzaku Mitori was with Xochitl when she received a call from Baba Yoshio asking for a safe place to hide after Misaka Mikoto destroyed his Type:Mantis and threatened him. Hearing that Mikoto hadn't been stopped, Mitori decided to head out. After being warned by Xochitl about Mikoto's strength, she said that she didn't have to defeat her and that she'd have things cleaned up within the day.

Mitori hacked into the visitor ID GPS system to locate Misaka Misuzu to use as a hostage. Finding Misuzu with Uiharu Kazari, she said to herself that having another hostage wouldn't hurt. She later approached Mikoto via her Liquid Shadow puppet in disguise, telling her that she wanted to ask her about something. When Mikoto mentioned she had no time to speak to strangers but would make an exception to anyone connected to the person who hurt her friend, Mitori revealed an unconscious Uiharu and held a knife towards her throat.

After getting Mikoto to end her phone call and throw her phone away, Mitori mentioned that she had no need to introduce herself seeing as how Mikoto attacked their villas and stole their information. When Mikoto asked what she's talking about, Mitori told her not to play dumb and that she should know what they were after - where the Sisters were being hidden. Mikoto asked why she was attacking her friends but Mitori asked her back if she could really say that, calling her an oddity for living a carefree life despite knowing what was going on in the city, mentioning about experiments on Child Errors, the trick used to obtain her DNA map and the inhuman Level 6 Shift experiments, all leading up to the highest levels of Academy City. Mitori said that Mikoto was different from the average ignorant student yet she turned a blind eye and lived an everyday life, asking her how she could remain calm despite all this.

Mikoto started to reply but changed her mind, saying that it had nothing to do with this and that none of this was an excuse to hurt her friends. Saying she had nothing to tell her, Mikoto warned Mitori to let Uiharu go, saying her electricity would reach her before she could move her knife. Mitori then mentioned how she thought she was Mikoto's friend seeing how she knew her mother. She then pointed to Misuzu, also held hostage. Saying that not even Mikoto could save them both and that it was clear that she didn't need to weigh their lives against the location of the clones, Mitori once again asked where the clones are. Mikoto again said she has nothing to say to her. Mitori asked Mikoto if she thought she was bluffing or if she was willing to let one of them die. Mikoto then declared she would save Uiharu no matter what. Mitori laughed and asked if her mother was expendable. As she remarked how cruel that was, Mikoto attracted some pipes with magnetism to pull Uiharu away while attracting her phone to block the knife, before moving in and attacking with electricity.

Seeing that the negotiation had failed, Mitori attempted to carry through with her threat, saying she wouldn't like it to end with Mikoto underestimating her and telling Misuzu to resent Mikoto for abandoning her. At that moment, Shirai Kuroko teleported in and threw her wheelchair down at her. Jumping out of the way, Mitori threw a knife at Kuroko, who evaded it. She then escaped as Kuroko was teleporting Misuzu to safety. As she was escaping, she had her liquid metal puppet attack Kuroko as she was moving to apprehend it and walk towards Mikoto, pointing towards her with a smirk before it dissolved as Mitori moved out of range. In the sewers, Mitori remarked that they couldn't have Mikoto dying yet, saying that direct negotiation was hard, though necessary as she could do too much over a camera. She then thought back on the conversation, thinking that Mikoto had no reason to feign ignorance, but they determined it was her from the witnesses. She then considered that the witnesses may have lied, or had their memories altered. Thinking about Mikoto's expression back then, she then said that there may be some hope left.

Mitori later reported to Gensei that it was Shokuhou Misaki who was the real culprit behind the attacks on their villas, only to find to her slight dismay that Gensei already knew. Gensei then told her to continue with her preparations.

When Saten Ruiko investigated the Liquid Metal factory and was threatened into leaving by Xochitl, Mitori's puppet attacked Saten when she turned round, slicing her backpack, coming out of the pipes and scaring her into running off. She then asked Xochitl why she let her get away to which Xochitl replied that since the supposed plan was in its final stage, she didn't think she could interfere at all. Mitori replied that was no reason to let her live and went off with a subordinate to catch Saten.

After capturing Saten, Mitori remarked how she was an energetic rat as she struggled against her captors. When the subordinate asked what to do with her, Mitori told him to find out why she came there then dispose of her, saying she has something she needs to do. She turned to leave but turned back when Xochitl appeared and dispatched the subordinates.

Mitori asked Xochitl if she was betraying them or if she cared for Saten. Xochitl replied that she didn't care for the idiot but Mitori was the real traitor. She then revealed how the Professor had become aware that Mitori had used her position as a go-between to have MEMBER carry out jobs from someone outside the Board of Directors. After Xochitl declared her intention to punish her, Mitori asked if it wouldn't result in a one-sided slaughter, to which Xochitl told her not to assume she's safe where she's hiding, stating that Mitori doesn't know all of her spells. Mitori thought that this was probably a bluff, but noted that Xochitl's power, coming from outside Academy City, might be able to produce an unexpected phenomena. Considering that she couldn't afford to mess up, Mitori decided to retreat, leaving Xochitl a warning that she should leave Academy City if she wanted to live much longer.

Later, when Gensei initiated his Level 6 Shift attempt on Mikoto, Mitori looked on from a nearby rooftop, smiling. She then used her access to Exterior's Mental Out, granted by the Level Upper, to communicate with Mikoto, who wasn't properly conscious due to the shift which was being forced on her. Reminding her of the atrocities she'd seen, Mitori pointed out the Windowless Building and that everything would continue as long as it stood, suggesting she destroy it.

Mitori then watched in amazement as Mikoto unleashed a huge lightning strike on the Windowless Building. She believed that the building had been destroyed, but to her dismay the smoke cleared to reveal it unharmed. She then called Gensei, asking what was going on as this wasn't what as he said, to which Gensei replied that the building couldn't be damaged by attacking in head-on and that Mikoto was still growing, remarking on how impatient she was. He reminded her to carry out her duty if she wanted to achieve her goal, giving her another task to perform.

As Misaki met Keitz Nokleben on the roof of the Exterior building, Mitori attacked with her puppet, snaring Misaki's leg. As Misaki tried to use her remote, Mitori added to Misaki's earlier remark that only someone with Mental Out could oppose Mental Out, saying something remote controlled could also handle it. She then told Misaki to come with her and not resist. Her puppet's limb was then suddenly severed by a shard of metal, teleported by Kuroko.

As Kuroko declared her intention to arrest and question everyone present, mentioning Mitori's falsification of the Bank's data, Mitori attacked with her puppet. Kuroko evaded her attack and at Misaki's request, teleported Keitz and Misaka 10032 to safety. Mitori attempted to attack the two but Kuroko teleported herself and Misaki away. As Mitori had her puppet repair itself, she remarked on how they'd found her data in the Bank that soon. Noticing Kuroko moving to pursue her, Mitori informed Gensei that she'd failed to capture Misaki, asking him to handle her as she needed to protect herself. She also suggested to Mikoto to swat away the "fly" that was bothering her.

As Kuroko was searching for Mitori in the buildings near to where Mikoto was, Mitori had her puppet slice through a door to attack her. Kuroko then proceeded to engage the puppet in combat. Evading its extending limbs, she sent a stake into the camera around it's neck and used a device to deafen her echolocation to escape. After piercing the device, Mitori sensed Kuroko was heading her way. Realizing that the security cameras likely gave her location away, she had her puppet slice and enter sewer pipe to head to where Kuroko was, then proceeded to use it to destroy the cameras nearby. Turning her attention to Kuroko, she used a floating camera to target her when she used the sonic device and stabbed at her with her puppet, spreading out her attacks to suggest she was trying not give herself away while viewing directly.

Mitori's puppet caught up with Kuroko through a vendilation duct, as she reached the last blind spot in the building. As Kuroko used another device to seal her echolocation, Mitori turned to the camera, believing luck was still on her side. Considering the lag when Kuroko teleports and the location she was likely to jump to, Mitori had her puppet fire a knife hidden inside it towards her. She saw Kuroko get hit by it and then saw her lying dead on the floor below. Laughing madly, Mitori apologized, saying she wouldn't have killed her if she hadn't interfered, though she added that she'd have met the same fate when the city was destroyed.

Sensing Mikoto's progress, Mitori then guided her into creating a black sphere, aimed at the Windowless Building. Mentioning that though Mikoto could destroy the city she had to make sure that that person was definitely eliminated, Mitori told them to apologize to "her" in the afterlife, yelling for Mikoto to blow them away. She then heard something behind her and turned to see Kuroko, who had realized she was hiding in the sewers. Mitori was shocked that her camera, out of the thousands around, had been hacked with dummy footage, to which Kuroko replied she had the ultimate partner for that. Kuroko then declared she had nowhere left to run.

Cornered and with no time to call her Liquid Shadow, Mitori reached for her knives, thinking about how she didn't just come down there to hide but also in case she was tracked down, as the passage limited teleportation. She then planned to shoot Kuroko with her ballistic knife when she teleported to avoid her first knife, taking advantage of her lag, taking both of them down if she attacked via teleportation instead. As Kuroko moved forward, Mitori threw the first knife, but to her surprise instead of teleporting Kuroko intercepted it with her hand. Not reacting fast enough, Mitori was punched then kicked down by Kuroko. Screaming, she lunged at Kuroko with the second knife but Kuroko teleported and kicked her in the back of the head. As she fell, Mitori thought of Dolly before losing consciousness.

Abilities
Mitori is a Level 4 esper, with the ability is known as Liquid Shadow (液化人影(リキッドシャドウ)), which gives her free control over liquids with a specific gravity of 20 or greater, which in her case, she prefers the use of liquid metal. The ability gives her high combat ability and she can remotely control the liquid from even several hundred kilometers away.

She uses her ability on liquid metal to make and shape forms out of it. She however has shown that she uses it form and control a copy of herself. This puppet is capable of manipulating its body parts to create weapons which can be as sharp and agile as a butterfly knife, and can withstand electric attacks and having objects teleported into it. However, it appears that the puppet dematerializes into a puddle when Mitori goes too far away from it. Mitori is unable to see through her puppet, instead using a form of echolocation to detect heartbeats within a few dozen meters of her puppet and a skull shaped camera worn around it's neck. She can also seen using several Homing Cameras after the skull shaped camera is damaged, though depending on the angle of the Homing Camera she has to spread out the attack and even then not generated to hit the target properly. The puppet can also hold objects inside its body and can propel them outside, as when Mitori made it throw a knife hidden inside it to give Kuroko a lethal blow.

The "Liquid Shadow" only has the senses of hearing and touch, which compensates by having a puppet wear a collar with a camera on it. She also has some difficulty with precise body control if it does not have the same volume and shape as her own body.

Equipment
She carries knives with her for emergencies, including a throwing knife and a ballistic knife. Mitori is proficient with using and throwing knives.

Trivia
