Uiharu Kazari/Chronology (Toaru Kagaku no Railgun)

This article covers Uiharu Kazari's chronological history in Toaru Kagaku no Railgun.

Level Upper Arc
As a member of Judgment and friend of Kuroko she introduces her friend Saten Ruiko to her and Misaka Mikoto.

Although her esper abilities never come into use and despite her weak physical attributes, her skill in computers makes her a great asset for Judgment and is very reliable. This was shown during the Level-Upper arc, she realizes that her friend, Saten, had used Level-upper and had become comatose as a result, which makes Uiharu exert more effort in trying to discover the culprit, because of this she is the first one to discover Kiyama Harumi's intentions and is instrumental in helping Mikoto defeat the AIM Burst creature and revive the comatose users of the Level-Upper. In the end she tearfully reunites with a now conscious Saten.

Big Spider Arc
She first appears listening to Kongou Mitsuko's testimony on Big Spider's attack on her. Uiharu later appears listening to Konori Mii about Big Spider and praises her senpai for having such knowledge. She is later with Saten, Mikoto and Kuroko talking about the recent attack on Kongou. She appears in the Judgment office and gives information about Big Spider and their leader before Mikoto and Kuroko leave. She is then seen eating together with Saten, and is told by Saten that she understands the feelings of Skill-Outs and is reassured by her that she will never again give up.

In the next episode, Uiharu is seen with Kuroko, Saten and Mikoto talking about Mii and Kurozuma Wataru's relationship, she also tell them that Mii has not been in Judgment for a while now and is not answering her phone. She later joins Mikoto, Saten, and Kuroko to go to Mii's apartment, where they meet her roommate, Yanagisako Aomi who tells them about Mii's past as a member of Big Spider. She later leaves with them and then later listens to Saten's reply to Mikoto's statement about Mii's past.

Poltergeist Arc
During the second arc, she becomes friends with Haruue Erii and is responsible for her, so much so that she quickly disregarded any suspicion towards her by Kuroko as the culprit of the Poltergeist events despite overwhelming evidence. During the previous arc she bonded with Harumi and trust her more as such she convinces her to hand out all her research to Therestina Kihara Lifeline.She later breaks down when she discovers Therestina's intentions of using the Haruue and the rest of the Child Error students of Kiyama Harumi. During the retrieval operation she aids Kiyama in navigating the highways of Academy City and pinpointed the location where children are kept. Finally during the final confrontation between their group and Therestina. She becomes incapacitated by Capacity Down but not before making Therestina talk where the machine to operate Capacity Down is located which allows Saten to find and destroy it.

She is last seen with Saten, Misaka and Kuroko being late for the special event held by Haruee Erii for Kiyama Harumi.

Sisters Arc
Uiharu is briefly seen doing her summer homework, as she was busy with Judgment work all-summer. Mikoto suddenly calls her and asks her about the password she heard from Misaka 9982. Uiharu is successful in breaking the code which allows Mikoto access to the Level 6 Shift Experiment details. It is unknown if Uiharu herself read the files. At a later date, Uiharu, along with Saten Ruiko, is talking to Haruue Erii on her phone. Erii says she will join them later after stopping by the hospital. They meet up with Kuroko to help her with Mikoto. Learning that Mikoto has being busy recently and isn't talking to her, Saten concludes that Mikoto has boy problems which makes Uiharu blush. Later after hearing an alarm from a vending machine, Uiharu tries to go and assist Kuroko, who turns her down thinking that it is a false alarm.

Silent Party Arc
Before the events of the arc start in earnest, Uiharu helps Haruue Erii prepare for her move and is disheartened by this, despite only getting to know for her for a single summer. Regardless, Uiharu tries to put on a facade of strength towards everybody while helping Erii. She is with the other girls when they visit Edasaki Banri when she is finally released from the hospital. When she and Kuroko are called by Konori Mii to help relieve a traffic jam that was caused by STUDY, she jumps at the call and tells the others to go ahead and start their celebration for Erii without them. After they have done their duties, Uiharu pleads to Kuroko to teleport her to the store where she bought the taiyaki she bought for Erii when she was in the MAR research laboratory. When they arrive at the cafe where the celebration was being held, Banri has already left for she had a appointed check-up.

As the other girls bicker around Uiharu's idea of giving taiyaki to someone who just had cake, Erii soon remembers that the box in her hands has the same taiyaki that Uiharu gave to her back then. Erii weeps upon remembering this well-cherished memory and vows to Uiharu that she will help Banri the way Uiharu had helped her. Eventually, the reality that she would move far away from Uiharu dawns on Erii, and she hugs Uiharu tightly. Uiharu, despite her best efforts to hold back her tears, and that they only met this summer, she eventually breaks down and cry.

As Saten comments on how childish Uiharu can be sometimes, Mikoto just lets Erii and Uiharu savor this moment.

When Febrie is introduced, it has Saten temporarily move into Uiharu's room, keeping her company after Erii had left. There, the two of them take care of the child. For the early half of the arc, Uiharu aids Saten in taking care of Febrie. When Mikoto tells them of Febrie's involvement in the dark side of Academy City, imploring for their aid to save her, Uiharu, Saten, and Kuroko jump at the call. She spends most of her time in front of the computer searching for information. She is later seen aiding Kuroko in breaking out Mikoto after she is caught by STUDY through the user of her computer-related skills.

Later, her tech-savvy allows her to discover that STUDY has delivered 20,000 Powered Suits to the Academy City Research Exhibition Assembly and that they were the ones who instigated several power outages to cover them up, one of which was the one where she and Kuroko were forced to relieve traffic. Despite the odds, they all decide to take on STUDY and the Silent Party without any help at all from Anti-Skill for the sake of Febrie and Janie, Febrie's sister. She is given the manual on how to pilot a Ekaterina II S along with Saten by Kongou Mitsuko, and memorizes it in a single night while making rice balls with Febrie. In the crack of dawn of the appointed day, Uiharu and Saten stand guard in one of the venue entrances against a group of Powered Suits controlled by Diffusion Ghost. Here, Saten wields her bat while Uiharu takes control of several security robots. They are later joined by a multitude of Judgment members. During the offensive, Uiharu takes advantage of the Powered Suits' simplistic AI and use the security robots to distract them long enough for the others to take them down. Later, Madarame Kenji and Kosako Shunichi of STUDY try to counterattack using their large mobile weapons. As they retreat Uiharu trips but is soon saved by the arrival of Yomikawa Aiho bringing the Ekaterina II S, and knocking out their mobile machines. This apparently gave the girls enough time to pilot and transform it into an even larger mecha. Saten and Uiharu's memorizing a manual in a single night proves useful as they are able to easily to take down the two mobile weapons.

Saten and Uiharu are part of the little conference held after Mikoto defeats Aritomi Haruki, STUDY's leader, who has launched the AIM bomb. When they decide to use the Ekaterina II S as a missile for Mikoto's Railgun against the bomb, Uiharu complains on how they need a super computer to calculate on how they will able to launch the thing into the atmosphere. After the Sisters little secret help with the calculations, Uiharu orders the girls to follow the specifications, with Kongou for her Aero Hand and Maaya with her Float Dial. She later witness the launching of the large mecha into the upper atmosphere, and later sees the debris shower of the explosion that Mikoto caused by using it as ammunition for her Railgun against the AIM bomb.

As Janie and Febrie are in a Kongou Airlines runway, preparing to leave to the outside for body readjustments, Saten cries over Febrie leaving. Uiharu tries to console her but also falls into tears. And thus, the fellowship, though bound by friendship and love, part ways.

Daihasei Festival Arc
Kuroko, Saten, and Uiharu appear right before Mikoto's competition in the three-legged race with her partner Kongou Mitsuko. Saten tells Uiharu of a substance known as Shadow Metal that is formed by the clashing of multiple espers, which can be sold for a large sum of money. Kuroko then appears right after, angry at Saten for spreading rumors again, to which forces her to distract and stay her anger by pointing out that Mikoto's competition is about to begin.

After their victory, Xochitl, in disguise, tries to operate the unique cellphone that is the same to the one that Shirai Kuroko uses. Confounded by the technology, Saten Ruiko overhears her and goes to her aid. However, seeing Saten, surprises Xochitl to the point of shouting. Saten seems to feel that they have met somewhere before (referring to the events of Liberal Arts City), but because of Xochitl she couldn't tell. Xochitl then says she must be seeing things as she looks like someone she knows, confusing Saten. Uiharu Kazari then calls out to Saten that they should now leave. Before that however, Saten focuses her gaze on her, and tells her that she feels like that they really have met before. Xochitl insists that she is just imagining things and that she made a mistake, to which Saten agrees and then leaves.

Mikoto, Uiharu, and Saten would later meet up with Misaka Misuzu. Mikoto notes that her clothes are dirty and that changing them would be difficult for the next event, to which Saten says that Mikoto should ask someone to go in her place. This however makes Mikoto accidentally divulge on her little bet with Kamijou Touma, which entices Misuzu and later has both Uiharu and Saten discuss the person who is "helping Mikoto a lot", much to her embarrassment.

As the day goes on, at lunch break, Saten Ruiko is still up on about with Shadow Metal despite Kuroko's warning on not spreading the rumor, and manages to convince Uiharu Kazari to aid her in finding it. Saten then goes to Kirigaoka Girls' Academy grounds in School District 18. With no event there scheduled, Saten is able to search all she wants with Uiharu's help who is constant communication with her from Judgment 177 Branch Office. Searching for information about Shadow Metal on the Internet, Uiharu notes on how there is an unusually high amount of hits, to which Saten says that there must be "something" if there is that many hits. Continuing on, Uiharu says that she can no longer find the website Saten was looking for, which confuses Saten as she was sure she was saw it about a week ago. Saten smells a cover up and talks about on how there is an organization that targets those who get close to the Shadow Metal.

Mikoto and Kuroko later arrive in the office as the former have a bit of time before her next event as Uiharu jokes to Saten that she might be targeted by the organization who wants the Shadow Metal. Immediately after, Saten is attacked by men in hazmat suits. Concerned, Mikoto asks Uiharu what is going on, to which he explains that Saten is being attacked by someone on the other line. Hearing this, Kuroko and Mikoto mobilized after Uiharu says that Saten is in Kirigaoka Girls' Academy grounds in School District 18. Uiharu is left behind for a backup as they might need to contact Anti-Skill. Arriving there, Kuroko notices them, but Mikoto, seeing Saten being held down angers Mikoto and attacks them. Mikoto and Saten later prostrate themselves in apology to them after it is revealed that they are the one who clean the grounds after an event to prevent the DNA traces of espers from being stolen by outsiders. Seeing Saten as a trespasser in the grounds, it was only natural for them to apprehend her. They are later let go by them. Kuroko says that the rumors of Shadow Metal spread because of the fact that the grounds were heavily guarded to prevent DNA maps from being stolen, and berates Saten for being carried away by a baseless rumor, as well as Mikoto for the attack.

Back with Uiharu, she is relieved that her friends are okay and check back to her search earlier. She notes on how it was unusual, saying that it as if someone is releasing a lot of false information in order to hide something. As Uiharu digs deeper, she is able break through Keitz's automatic dummy generating programming and arrives in Auribus oculi fideliores sunt. She is at first dismissive of the urban legends and rumors catalogued there, but later comes upon the report on Shokuhou Misaki and the location of Exterior. Keitz later notices someone breaking through his setup, frustrating Misaki as Keitz promised her that no one will find the website. Keitz then says that in the off chance this event happened, he had set it up to back trace the intruder. Here, they discover that it is from Judgment 177 Branch Office. Wanting to confront the intruder herself, she goes to the branch office. Shokuhou uses her powers to delete the data from the computer, though it can still be retrieved. Misaki later uses her powers to search her memories and discovers that Uiharu is friends with Mikoto, she then brainwashes Uiharu to forget what had happened to her. Moreover, she later modifies her memories in order to have Uiharu change the patrol route she and Kuroko were going to the next day in order for her and Keitz to catch up to all of them. Having the foresight on Mikoto interfering, Misaki's intention on manipulating Mikoto's friends memories is to keep Mikoto in a leash and constraining her actions, as it stops her from enlisting the aid of her friends and from forcing her way out of her clique.

The others later arrive, and much to Kuroko and Mikoto's chagrin, Saten then immediately asks Uiharu if she had found any new information. Uiharu then says that she has done some searching herself but couldn't find anything. That night, Saten introduces Uiharu to her parents

The next day, Misaki makes her move against Misaka Mikoto. Uiharu, as programmed by Misaki, takes Saten and Kuroko away from their proper patrol route. Kuroko realizes that they are in the wrong route, which surprises Uiharu truly believed she was going the right way. Then, Keitz appears behind them, pretending to be an outsider in need as a distraction. Misaki later comes out of an alley as they are distracted and uses her powers to freeze their movements, preventing Kuroko from using her powers, and later erases their memories of Mikoto. As Mikoto tries to escape Misaki's clique, she notices Kuroko, Uiharu, and Saten walk along by. She is relieved and comes towards them, but much to her horror, discovers that they too have been brainwashed by Misaki. Mikoto is greatly angered by this affrontary, but is unable to do anything even if she tries to convince them that she is truly their friend. Moreover, Mikoto has another event to partake in.

Kongou, fresh out of her latest event, later meets up with Kinuho and Maaya and later stumble upon Kuroko and the others. Kuroko later airs her frustration on Mikoto coming up to her, making an accusation, and then asking them if they were joking. This surprises Kongou, Kinuho, and Maaya, wondering if Kuroko and Mikoto had a fight. Back with Kuroko and the others, she wonders on how Saten and Uiharu knew Kongou. They point out to her that they met when they were visiting Kuroko in the hospital, though this confuses Kuroko as she is not close with Kongou. The others can only conclude that there was a mutual acquaintance but cannot remember who.

The girls go their separate ways for the moment, with Uiharu going through her Judgment duties, unaware of the battles that have taken place. Misuzu meets with Uiharu, who still knows her as Misaki had only erased their memories of Mikoto. She sees Uiharu with a lost boy for his father to pick him up. Uiharu divulges on how the IDs of the visitors have GPS functionality, and as such can be tracked by Judgment headquarters if someone is lost. As they talk together, Kouzaku Mitori later finds them both and knocks them unconscious intending to use them as hostages against Misaka Mikoto.

She and Misuzu are later saved by the efforts of Mikoto and Kuroko, and are later taken to Judgment 177 Branch Office. When she wakes up, she overhears Saten's hypotheses regarding Uiharu being controlled by Misaki since yesterday, leading to them to conclude that is the reason why Uiharu took them to the wrong patrol route. Saten then says that they should keep it a secret from Uiharu, saying that she is the type that to feel responsible when no one is to blame. Just then, Uiharu has woken up from the infirmary opens the door and asks them to tell her exactly what they are talking about, to which Kuroko agrees, much to Saten's shock. She however, says that Uiharu should first make some tea. Kuroko whispers to her that she admires that she is protecting Uiharu, she says that she isn't that weak to have that break her. After being briefed about it, Uiharu is dismayed for being manipulated. Kuroko however says that after their break they should restart their investigation, and asks Uiharu if she can look through the Bank for anyone suspicious. Uiharu asks if she is sure that she can trust her, to which Kuroko says that they do not have time to have a detailed examination as they need her skills now. She then tells her that if she is really worried, then she can do her work in front of them. Uiharu goes right to it, impressing Saten.

As the investigate liquid metal, Saten notes that only two companies that have developed liquid metal have survived. Kuroko says that the companies have no record of loss or theft, which opens up the possibility that someone inside the company is helping the esper using liquid metal (Kouzaku). Just then, Uiharu has finished the search according to Kuroko's specifications and they discover that the name of their attacker is Kouzaku Mitori. Findin information about her, Uiharu says that Kouzaku is in the Reformatory for an attempted terrorist attack 14 months ago. Saten asks if she escaped, to which Uiharu says that if she did, then Judgment should've been notified. Uiharu asks again if Kouzaku truly was the culprit, to which she confirms. Regardless however, Kuroko wants to double-check and says she wants to go to the Bank's control center. Uiharu then asks what Saten would seeing as she will likely not be allowed there as she is not a member of Judgment. Saten says that she will pass and asks about Misuzu, to which Kuroko says that she has explained the situation to Konori Mii their senpai. She says that Mikoto wished for Misuzu to be told that she collapsed of heatstroke and that she will be kept in the office for protection under the guise of getting a new ID issued.

With that they all leave the office, with Kuroko and Uiharu going to the Bank's control center. When they arrive, Kuroko discovers that Kouzaku has been dead for at least two months due to heart failure. Kuroko wonders if she was wrong in her assumption, but then finds something odd. She discovers that her body was incinerated immediately after she was found instead of getting an autopsy. Then, the minder in the Bank comes up to them and says that Kouzaku may not have one. She explains that they might have something to hide and that they destroyed her body, evidence, before the true cause of her could be found. She also says that Kouzaku might not even be dead. When asked, the minder says that there is a rumor about the Reformatory, and on how student suddenly disappear for some reason. When the guards report it they are waved off and ignored and it is always high level espers or excellent students who disappear. She says that Academy City makes a deal with the esper or student and releases them in secret and then fake their s as it is far more convenient, though she says it is just a rumor.

They are later contacted by Saten Ruiko after getting information from Xochitl regarding the situation Mikoto is in. Kuroko then teleports to School District 2 as the Level 6 Shift attempt on Misaka Mikoto takes place. Saten and Uiharu later aid Kuroko as she does battle with Kouzaku Mitori.

Kuroko teleports from building to building trying to find Kouzaku. She recalls Misaki's informing her, in that Mental Out isn't very effective on Mikoto, and as such the Liquid Shadow puppet cannot give Mikoto orders. This leads her to conclude that Kouzaku can only guide Mikoto's psyche if she is nearby. However, with such a high concentration of research facilities near where Mikoto is, Kuroko contacts Uiharu and asks her to check every camera within 800 meters of School District 2's Judgment building. She tells Uiharu to see if she can find Kouzaku on one of the cameras as well as a list points the cameras do not cover. Uiharu asks Kuroko if she needs backup, to which Kuroko says they do not have time.

As Kuroko teleports into one of the buildings, Kouzaku has her puppet slice through a door to attack her. Kuroko then proceeds to engage the puppet in combat. As she battles, she finds out where Kouzaku puts the camera on her Liquid Shadow puppets so she can see, which is on her neck. She attacks it with her darts, disabling Kouzaku's secondary senses, and forcing her to use echolocation to grasp the situation, Kouzaku's primary sense for her puppet. She then uses a small device to deafen her ability to echolocate. Kuroko then teleports away as the puppet is preoccupied, trying to search for Kouzaku. However, the facility is so vast, she requires the aid of a clue. Back in Judgment 177 Branch Office, Saten manages to find Kouzaku in one of the cameras. Uiharu contacts Kuroko, telling her of Kouzaku's moving into an alleyway three minutes ago, though she can't tell what building she's in as she hasn't been seen in the other cameras. Kuroko then rushes toward the likely location of Kouzaku.

Kuroko asks if they're sure Kouzaku hasn't been seen in any other camera, to which Saten confirms. Kuroko notes that Kouzaku would show up in the cameras if she moved into another building. Seeing this, Kuroko manages to pinpoint the building where Kouzaku is likely hiding in. She orders Uiharu and Saten to turn all nearby movable cameras toward the building as she teleports in.

Back with the puppet, Kouzaku is able to pierce the device, but then realizes that the security cameras likely gave her location away. She then has her puppet slice and enter a sewer pipe to head to where Kuroko is going. Uiharu notices this as well, and reports it to Kuroko, confirming to her that the place where Kuroko is in is where Kouzaku is hiding. Kouzaku, turns her attention to Kuroko, and uses the cameras of the Homing Cameras that is used for Daihaseisai events to target her. Kouzaku observers the battle directly during the puppet's confrontation with Kuroko in the building. After Kuroko uses the anti-listening device on her puppet again, Kouzaku uses the puppet to attack her, though could only spread her attack as she could not tell how high up Kuroko is. Despite being hit on the side and on the arm, Kuroko teleports away and applies a small a balm on her injuries. While doing so, she believes that Kouzaku is in the building based on the puppet's actions and that she is in the upper floors. After treating her wounds, Kuroko pursues Kouzaku from below, though notes that she may be overlooking something.

Meanwhile, back in Judgment 177 Branch Office, Saten and Uiharu becomes worried of Kuroko's injuries. Uiharu, as she watches the cameras, later catches the Daihaseisai Homing Cameras surrounding the building where Kuroko is in despite being no events. Uiharu researches that Anti-Skill apparently used them to see if anyone has yet to be evacuated but notes on how the powerful electromagnetic waves there are too powerful for the cameras to approach. Saten then gets the idea in having them use the cameras to aid Kuroko, leading Uiharu to eureka moment. She asks Saten how long the cameras were there, to which she says that they have been there since Kuroko entered the building. Uiharu then reports this to Kuroko, giving to her the possibility that Kouzaku is not inside the building but somewhere else.

With this new knowledge, Kuroko continues her pursuit of Kouzaku inside the building. Kuroko finds the last blindspot of the building, only to find that she isn't there. Kuroko goes over thoughts once more, and discovers that Kouzaku may be hiding in the sewers and that she was led into a trap by Kouzaku. Kouzaku's puppet later catches up to Kuroko a ventilation duck. As Kuroko uses another anti-listening device to seal her echolocation, Kouzaku turns one of the Homing Cameras she has hacked toward the blind spot. Considering the lag when Kuroko teleports and the locations where she is likely to jump to, Kouzaku has her puppet fire a knife hidden inside it towards Kuroko. However, unbeknowngst to her, Uiharu has hacked that particular camera to display dummy footage, allowing Kuroko to escape.

Uiharu later becomes exhausted after hacking the camera and is later fanned by Saten, praising her for her hard work. Kuroko later manages to find the real Kouzaku and defeat her, ending her manipulation of Mikoto.

After the battles come to a close and Mikoto is turned back to normal, Misaki uses her power to restore the memories of Kuroko and the others' memories of her, though modified the events somewhat for them, making the believe that they were out trying to catch terrorists targeting the festival to avoid contradictions. Apparently all to hide the existence of both Exterior and the Sisters from public knowledge, as well as passing along the information on the virus to Heaven Canceller to treat the sisters. Mikoto's not participating in the festival events on the second day was changed as well to that of her eating too much and having her stay in the bathroom all day, much to her chagrin.

All the girls visit the field where the bonfire folk dance is being held and comments on how they are unable to dance. Mikoto goes away to buy them all drinks. In the meanwhile, Kamijou Touma later meets up with Saten, and thanks her for the protective charm she lent. Touma offers her to buy her some food to make it up to her, though she says that it is all right. Mikoto later comes around with the drinks, and finds Touma talking with Saten. Touma says that he borrowed a protective charm from her, confusing Mikoto though later figures out it was for the borrowing race. Mikoto's stutters and awkward way of presenting herself to Touma does not go unnoticed before the eyes of Saten and Uiharu.

Capitalizing this new found knowledge, Saten approaches Touma and asks him to dance with her around the bonfire as a way to thank her for lending him her protective charm. Touma is fine with the idea, though asks if she is sure with it, to which confirms. Saten then tells Touma to go on ahead, leaving the girls alone. Mikoto is utterly shocked by what has transpired, but with a knowing look between Saten and Uiharu, they make their move. Saten fakes an ailment finally catching up to her, prompting Mikoto to ask her if she is okay. However, Kuroko suddenly figures out their ruse and tries to tell Mikoto, but Uiharu comes up behind her and covers her mouth. With this ruse finally set up, Saten says that she can't move but tells Mikoto that she can dance with Touma in her place. Mikoto becomes embarrassed by this, and makes up a bunch of excuses. Fed up with this, Saten forces Mikoto to say that she wants to dance, to which she does.

The girls later see Mikoto dancing with Touma which is unceremoniously interrupted by Kuroko, teleport dropkicking Touma away, much to Uiharu and Saten's disappointment.

Dream Ranker Arc
While walking to school one day, Uiharu has her skirt flipped by Saten yet again. She later has a Judgment patrol with Kuroko. She tells her about a recently-popular treasure hunting smartphone application that can supposedly show pictures of incidents that will occur in the future. After she explains the details of the app, Kuroko decides that they must investigate.

They head to a road where an accident is predicted to occur. While waiting, Uiharu sees a Judgment recruitment ad and hopes that their branch will get a new recruit, so that she has someone to look after. They wait for ten minutes and nothing happens, causing Kuroko to get frustrated. A traffic accident suddenly occurs and Kuroko saves the would-be victim, then tells Uiharu to direct traffic until Anti-Skill arrives. While Uiharu follows this order, Kuroko locates and meets the app's creator Miyama Shaei, who was watching from afar.

They head over to the Judgment office to talk, and Uiharu offers Shaei some tea. Shaei explains how his precognitive power works and asks them to keep the true potential of his power secret. He also says that he was never able to alter the incidents he predicted by himself, so Uiharu speculates that Kuroko's teleportation (which works in 11 dimensions) allows her to interfere with the incidents. Shaei then makes a prediction in front of them to prove his power. This allows them to find and save a drowning girl. The three of them work together to prevent several more incidents.

Shaei eventually predicts that two concurrent events will happen in the same park the next evening and fire will be involved. They therefore enlist more Judgment members to search and set up checkpoints around the park. Uiharu gives Kuroko a device that will let her see a real-time satellite image of the park, though Kuroko disapproves of Uiharu hacking the satellite for this. Kuroko points out that the cherry trees are blooming out of season and the two of them wonder what caused this. Kuroko is then called away by Shaei.

Uiharu and the other Judgment members are at the park on the evening of the predicted fire, but have yet to find anything suspicious. The fire suddenly begins, and Judgment evacuates the civilians but has trouble due to the unnatural speed with which the fire spreads. Kuroko deduces that the plant ampoules placed beneath the cherry trees have made them more flammable, and Uiharu uses this theory to predict the fire's further spread. All of the civilians are evacuated successfully, but Shaei arrives and begs them to save a stray dog. Uiharu uses the satellite footage to narrow down the possible locations, allowing Kuroko to save the dog as well.

After the incident is over, Uiharu advises Shaei to stay away from Kuroko, calling her a pervert. She later explains the cause of the fire to Kuroko, including how the culprits (who were only trying to make the cherry trees bloom year-round) learned how to make the ampoules from Indian Poker. They meet Shaei again, but he reveals what Uiharu said about Kuroko, causing Kuroko to chase Uiharu and wrestle her to the ground. Uiharu tries to escape by changing the subject, talking about how everything worked out in the end, but Kuroko sees through this. They then return to work.

Later, Uiharu and Saten walk along with the latter talking about her plans with Indian Poker. They pass a girl with large breasts (thanks to using the Indian Poker card "Bust Upper") and are both amazed. Saten marvels at the size, and Uiharu says it's rude to talk about this.

Uiharu meets Saten after the latter is questioned over her involvement in a recent incident. She tells Saten that she has to stay in an Anti-Skill facility for the next few days for her safety. She also says that no bodies or injuries were found at the department store where the incident occurred. She finishes by saying that they should move now and that Judgment will provide everything that Saten needs.

After Saten moves back to her apartment, Uiharu visits to report that everything's fine. A dejected Saten invites her in for dinner, as Frenda Seivelun (who she planned on having dinner with) never showed up.

At a Judgment meeting, Uiharu tells her colleagues about recent leaks of information from the School Garden and major companies, concluding that Indian Poker is the cause.

After the Indian Poker incident is resolved, Uiharu talks with Saten about urban legends, such as the story of the talking golden retriever. They walk through the city exploring the sites of urban legends. They come to a water reservoir that is said to contain a mutant giant serpent. This leads them into a conversation with two gyaru girls, one of whom claims to have seen that serpent three weeks ago. She shows them a photo she took but the serpent is out of focus so Uiharu and Saten are skeptical. Saten thanks Uiharu for letting her see various urban legend sites to cheer her up. She asks her if she'll disappear in the future, and Uiharu promises that she won't if Saten doesn't look so sad again. They then run into a flustered Mikoto. Mikoto tells them that a "friend" of hers has realised that she may have special feelings for someone (i.e. Touma), but is depressed since that someone seems to like "symbols of motherhood" (i.e. large breasts). Saten asks if Uiharu has any advice, and Uiharu says that, if this boy won't ignore anyone in need, all the friend has to do is experience a tragic situation and to stay in such a state of tragedy. As a confused Mikoto listens to Uiharu's advice, Saten desperately tries to keep Mikoto from being misled by this advice.

Jailbreaker Arc
Uiharu watches a news program about the opening of a private juvenile hall for espers. The hall's director, Kyougoku Ryouta, announces a Jailbreak Trial in which espers will compete to try and break out a fake prisoner from his hall. Saten is excited by the one billion yen prize money, but Uiharu doubts that they expect to actually pay it. Mikoto is goaded into participating by Kyougoku's boasts (that his hall could hold even Tokiwadai students) and the other three end up participating as well.

While lining up outside the juvenile hall, Uiharu shows the others a map of the facility. The trial begins. Uiharu asks Saten about the oversized gloves she's wearing. Saten explains that they'll let her climb the outer wall, but Uiharu points out that this would be physically demanding and would make her a sitting duck for the hall's defences. Another group of participants is sent flying by an acoustic weapon, forcing the others to cover their ears. Kuroko then teleports the group past a pitfall, but can't use her power any more because of the hall's AIM Jammers.

Uiharu and the others observe other competitors trying and failing to get past the wall. Saten plans to use her gloves to climb it, but Uiharu points out others who have the same idea (and fail). Kongou and her friends approach, planning on launching logs at the wall to breach it. This fails and logs are sent flying everywhere, so Mikoto protectively embraces Uiharu (because of her injury) while kicking Kuroko out of the way of a log. Uiharu thanks Mikoto and then smiles, though Kuroko is jealous of her for being embraced by Mikoto. Mikoto makes her own attempt to breach the wall, which fails, and then has an idea. By cooperating with the other competitors, they successfully create a lasting hole in the wall. However, all the competitors rush in at once and Uiharu is separated from the rest by the crowd. She tells them to go on without her and that she'll continue on her own.

While the others try to break the prisoner out, Uiharu pre-empts all of them by hacking the juvenile hall's systems. She makes the surveillance cameras show recorded footage and takes control of the guard robots to carry her into the hall, then to carry her and the prisoner out. Afterwards, the prisoner wonders if Uiharu analysed the security in advance, but Uiharu reveals that she hacked it on the spot be exploiting the habits and preferences of the human engineers who designed the security. Uiharu later takes part in a press conference where she receives a congratulatory plaque from Kyougoku.

Uiharu rejoins her friends and learns that Mikoto had figured out Uiharu's actions, since the entrance to the prisoner's building was opened without any signs of force (suggesting it had been hacked). When Saten asks what Uiharu will do with the prize money, Uiharu replies that she'll donate it to Asunaro Park (which dismays Saten). Uiharu says it's fine since she didn't win with only her power, she's scared of having so much money and, if she wanted money, she could hack an online bank. The last of these reasons causes Saten and Kuroko to be wary of her.

Later, Uiharu discusses the Jailbreak Trial with Mikoto and Saten in a restaurant. She tells them that the juvenile hall had a long-range AIM Jammer but didn't use it during the trial. Mikoto and Saten praise Uiharu's skills, though Uiharu realises that an angry Kuroko is behind her. Kuroko demands to know why Uiharu is skipping out on her patrol duty, but Uiharu claims that she is getting the energy to keep her brain at top performance. Kuroko stuffs a bun in Uiharu's mouth and drags her off to work.

That night, Uiharu calls Saten to complain about Kuroko. She hears a knock on the door and ends the call to answer it. She is kidnapped by Kimi and her group, Kimi being an actual prisoner of the juvenile hall who had tricked everyone (including Uiharu) into breaking her out, who are after her hacking skills.

Uiharu is rendered unconscious and taken away in a recreational vehicle (RV). Her friends track down the RV and attack it. However, they are repelled and Kimi's group continues to flee using two new vehicles. They drive along the entrance-way road that leads to School District 11.

Astral Buddy Arc
Hokaze Junko visited the Judgment office to discuss the dropped picture. Junko asked Kuroko if she knows someone good at investigation and she recommended Uiharu Kazari. Junko and the ghost headed to Sakugawa Middle School, where they met both Uiharu and her friend Saten Ruiko.
