Uiharu Kazari

is a character in Toaru Kagaku no Railgun. She is a Level 1 Academy City student, and along with her colleague and friend Shirai Kuroko, is a member of the student composed law enforcement organization, Judgment.

Etymology
Her name, "Uiharu" in Kanji (初春) literally means "Early Spring", and "Kazari" in Kanji (飾利) literally means "decorations" and "benefit". It is most likely referring to her flower headband, considering that flowers are a symbol of Spring.

Appearance
Uiharu is a small girl who sports short black hair and has golden-brown eyes. She has thick eyebrows but her most striking feature is her headband made out of artificial flowers. In the manga she often wears a facemask because she is easily afflicted by colds and flu.

Personality
Uiharu is usually shy and humble but always friendly. She is also shown as an equally high-spirited girl as is her friend Saten Ruiko. She admits that she is composed most of the time because of a so-called "limit" she places on herself. Without that limit, she is very energetic and can be airheaded at times as well, as shown during Tokiwadai Dormitory's Festival. Moreover, she is intrigued and interested in the Ojou-sama lifestyle, as shown with her trying to impress Kuroko with her tea making abilities, as well the above mentioned excitability of her person during the Tokiwadai Midsummer Festival. Although she is incapable of normal combat like Kuroko, she still has a strong sense of justice, being a member of Judgment, and will do her utmost to do her duty.

Apparently, she is an animal lover, as she was the only one of her friends that wasn't scared of Ekatrina, Kongou Mitsuko's pet boa constrictor, and even played with it.

Her vulnerability to flu is not shown in the anime version of Railgun, though this later disappeared in later chapters of the manga. The running gag on her not managing to eat her sweets ended in the Railgun anime as well.

Background
Uiharu is a 1st year student attending Sakugawa Middle School in class 1-D along with her friend Saten Ruiko who often teases her by flipping her skirt (which she does to Uiharu only). She is also known for wearing a headband of flowers (and in the Railgun manga, a surgical mask, as she constantly suffers from flu). She has a sweet tooth but is always called for Judgment duties before she can enjoy her sweets. She displays various advanced skills with computers, such as repelling hackers and gathering information.

She joined Judgment when she was still in elementary school along with Shirai Kuroko. They were caught in a bank robbery attempt when their senpai, Konori Mii, had been injured and Uiharu was taken hostage. After being teleported out of harm's way and subduing the culprits (with the secret help of Misaka Mikoto) by Kuroko, she and Kuroko vowed to mature and become better members of Judgment.

She later holds true to this, and joins Kuroko as a member of the 177th Branch office.

 * Main article: Tree Diagram Remnant Arc

Kazari first appears in the 8th novel, calling Kuroko regarding a stolen luggage bag with contents that are cooling parts that are installed on computers. Here, she believes that Kuroko is suitable enough for the case they are working on as the luggage bag that was stolen was addressed to a subsidiary of Tokiwadai Middle School. Even though Kuroko knows that there is no such subsidiary in Tokiwadai, and with other strange variables that are connected with the case such as the mysterious victim of the luggage bag stealing, electricity not working properly, Kuroko tries to end the case quickly by catching the robbers as the Anti-Skill that Kazari called will be delayed in their arrival.

Throughout the novel after Kuroko's utter defeat in the hands of Musujime Awaki, Kazari continually assists Kuroko in her mission, despite knowing that Kuroko is severely injured and that the case is beyond their jurisdiction. She gives various information regarding Awaki to Kuroko, like her strengths, weaknesses and other data like Awaki being a guide to the Windowless Building. Kazari later gives a rough estimation of Awaki's probable coordinates based on blindspots in Academy City's security system to Kuroko.

Battle Royale Arc

 * Main article: Battle Royale Arc

Uiharu Kazari plays a minor role in the arc. She first appears when Last Order, apparently sensing Accelerator near by, quickly leaves the taxi cab appropriated by Heaven Canceller for her to take her to Family Side the apartment building where Yomikawa Aiho's apartment is located, and where she resides. The taxi driver explains on how Last Order quickly left before he can give the change of the fare Heaven Canceller paid beforehand, which had an exorbitant amount that made the taxi driver feel guilty to take. Seeing Kazari as a member of Judgment, he transfers his conundrum to her, to which Kazari accepts. Taking the change, she quickly catches up to Last Order. She doesn't notice her similarity with Misaka Mikoto however, and asks her name, referring to her as "Ahoge-chan" (the hair that sticks up on Last Order's head), to which Last Order says her name.

Kazari is with Last Order when she was in the venue where Oyafune Monaka made her speech on children's suffrage, still looking for Accelerator, and referring to him as a lost child, and later Sunazara Chimitsu attempted to shoot her for SCHOOL.

She later attempts to hand Last Order to Anti-Skill after handing her the change, but had managed to snuck out and wandered the streets. She is with her in a train station in School District 7, lamenting her predicament. As she wonders about Last Order's strange name and powers, she asks her why the train isn't coming, to which Kazari says that there is a freight train coming. Kazari then asks in turn, asking her where she thinks the person she is looking for is, to which Last Order points to a direction. Seeing this, Kazari assumes that Last Order had a power to search the person she is looking for, though it was not very precise. Last Order becomes worried that she can't find the person, to which Kazari consoles her, though Last Order sees through how general her words of encouragement were, she still thanks her. Kazari tries to cheer her up by saying that she will give her a present. She takes one of the flowers from her hair, surprising Last Order, and says that it is hibiscus, which means "we'll, let's give it a shot". Last Order however says that the meaning is incorrect, to which Kazari ignores her and continued to smile as Last Order's energy returned. At the same as this, Accelerator happens to pass by in the sports car he has commandeered to take to School District 23. With Kazari none the wiser, she wonders where the people in the car were going to in such a hurry and states Anti-Skill should work harder to catch people like them. Meanwhile, Last Order started thinking about something.

Last Order later tires herself out in her search for Accelerator, prompting them to rest at an open-air cafe, where Kazari orders a parfait for herself. Last Order says that she is sure that the person she is looking for was nearby but suddenly went off somewhere. She then however notices a free gift key chain from a fastfood outlet and hurries towards there. Kazari is perturbed by this as Last order still needs to find that person she is looking for and that she wants to finish her parfait. She however, suddenly reminds her of the change from the taxi, to which she hurries off. As Kazari tries to eat her parfait, Kakine Teitoku approaches her, not even bothering to hide the conspicuous Tweezers he has equipped. He shows her a photo of Last Order and asks where she is. Last Order denies ever seeing Last Order, and advises Teitoku to go to the nearest Anti-Skill booth and ask them there. Teitoku seems to accept her answer, however, he suddenly hits her in the head. He tells her that he knew that she was with Last Order hence why he didn't ask Kazari if she knew the girl in the photo. Teitoku dislocates Kazari's shoulder with his foot, and begins torturing her. Teitoku knows that Kazari has noticed him and had Last Order escape. He says that he understands that she is not that capable, and though he is a scumbag he prefers not to involve normal people. He tells her that if she had cooperated with him in the first place he wouldn't have to resort to violence. He continues by saying that however he has no mercy for his enemies and that she has become one the moment she decided to protect Last Order of her own free will. He then asks her not to allow him to kill her. Kazari continues to be tortured by Teitoku, all the while bystanders don't even approach to aid her. In deep pain, Teitoku asks her again, to which Kazari mocks him, saying that Last Order is at a place he will never see. She then sticks her tongue out as a final gesture of defiance. Hearing this, Teitoku decides to finish her off with his foot. However, before he can do so, Accelerator arrives and throws an ATM machine at Teitoku, mocking him for attacking someone like Kazari. Teitoku's feet missed its aim, but Teitoku still however achieved his goal, something he tried to do through Last Order, and that is finding Accelerator. It is likely Kazari was taken to safety afterwards. It is unknown if she was there to witness the battle between the two top Level 5 espers of Academy City.

 * Main article:Silent Party Arc

Before the events of the arc start in earnest, Kazari helps Haruue Erii prepare for her move and is disheartened by this, despite only getting to know for her for a single summer. Regardless, Kazari 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.

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 Kazari'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 Kazari gave to her back then. Erii weeps upon remembering this well-cheished memory and vows to Kazari that she will help Banri the way Kazari had helped her. Eventually, the reality that she would move far away from Kazari dawns on Erii, and she hugs Kazari tightly.

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-savy 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 Ruiko 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, Kazari and Ruiko stand guard in one of the venue entrances against a group of Powered Suits controlled by Diffusion Ghost. Here, Ruiko wields her bat while Kazari takes control of several security robots. They are later joined by a multitude of Judgment members. During the offensive, Kazari 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 Kazari 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. Ruiko and Kazari's memorizing a manual in a single night proves useful as they are able to easily to take down the two mobile weapons.

Ruiko and Kazari 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, Kazari 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, Kazari orders the girls to follow the specifications, with Mitsuko 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 readjusments, Ruiko cries over Febrie leaving. Kazari tries to console her but also falls into tears. And thus, the fellowship, though bound by friendship and love, part ways.

Toaru Kagaku no Railgun: Uiharu SS
Published in a special booklet. Kazari stars with Yomikawa Aiho of Anti-Skill, where they try to stop a runaway tanker that is part of a terrorist plot.

Toaru Majutsu no Index Movie: Miracle of Endymion
Uiharu Kazari primarily plays a expositionary role in the first half of the movie, telling of the history of Endymion's construction, as well as its CEO, Ladylee Tangleroad.

She joins her friends in escorting Meigo Arisa in a photoshoot. She and the others are then forced to wear skimpy stage outfits, though she is more enthusiastic about it than Ruiko. She is later teleported away by Kuroko after the mall they were in is being bombed.

Later, she is in the Judgment branch with Ruiko when they discover that Arisa has been abducted. In the climax, she is joined by Ruiko during the attempt by Anti-Skill to break ingot Endymion. After an explosion rocks the space elevator and making it liable to collapse, she tells of a drastic plan of destroying the explosive bolts of the Endymion to break it away from the Earth. Both she and Ruiko overhear, Tsuchimikado Motoharu's "volunteering" to help them, as well as the Misaka clones telling that they will help, though she makes no comment on the latter.

She and Ruiko later witness the Miracle of Endymion. Here, she tells that Endymion is no longer collapsing as it happens.

Extra Franchise Cameo
Kazari appears quickly for a second in Ookami-san and her Seven Companions (also produced by JC Staff Animation Studios), looking confused at the audience, as a potential bride candidate for the boy millionaire Nezumi Chuutaro.

Abilities
Her ability is Thermal Hand (定温保存 (サーマルハンド) ), which allows her to conserve part of the objects temperature she touches, and is registered as a Level 1 esper.

Other Abilities
She is also very talented on the computer, as she can hack into almost all of Academy City's systems with ease. In fact, her main job in Judgement is working on the computer and use it to support the other members, such as picking up info on trouble makers. This more than makes up for her weak esper ability and lack of physical strength.

Uiharu had created a security system that is one of the 10 strongest systems of Academy City, which earned her a great reputation (and many challenges that led to the arrests of many skilled hackers) in the hacker's community under the alias of Goalkeeper. However, for some reason, the Academy City's Board of Directors did not trust in her abilities and didn't put her in charge of the public system, which created an odd situation that the Judgement's Office where she works has had stronger defenses than the databanks that holds all of Academy City’s data.

Along with Ruiko, she is able to memorize an entire manual on how to pilot a giant mecha in a single night and actually be able to apply it in battle. This is exemplified by Ruiko and Kazari easily defeating two mobile weapons.

Design evolution
Haimura designed Kazari with the theme that she would be a totally normal and uninteresting character without her flower headband. Haimura wanted to have the headband's flowers be in wilt or in bloom depending on Kazari's mood, though Haimura decided against this as it would not work for the limited illustrations of the light novel.

By volume 12, Kazari becomes affected by deformed artstyle that Haimura has for the characters. At this point, Kazari's skirt has been lengthened. The original clothes for Kazari had her with a short skirt, even up until volume 15. It is not until later that Haimura decided to lengthen her skirt for the Toaru Kagaku no Railgun manga. In the manga, Haimura gave out details in her expressions, stating that she is a gentle character in a comforting role, in contrast to Mikoto who is a strong character with a heroic role.

Trivia

 * She and Saten Ruiko have cameos in both openings of the Toaru Majutsu no Index anime.
 * In several omake chapters, it is joked about that her ability is to control plants. It might be supported by the quality of the flowers on her head, which is very realistically rendered in the anime and it's "growth" from her flashback as a Judgment trainee to the present. This is debunked in Episode 22 of Railgun, which displays a completely unrelated ability. The mystery of Uiharu's flower headband is solved in Volume 9 of the Light Novel, as it was described as "artificial flowers".
 * A character similar to her design appears in the 2nd chapter of Heavy Object a manga authored by Kamachi Kazuma, the creator of the Toaru Majutsu no Index series.
 * She has actually interacted with both Last Order and Misaka Mikoto, however she didn't notice any resemblance between the two.
