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.

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.

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.

Ability
Her ability is Thermal Hand which allows her to conserve part of the objects temperature she touches, and is registered as a Level 1 Power User.

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.

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.

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.

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

 * Her vulnerability to flu is not shown in the anime version of Railgun. Also, the running gag on her not managing to eat her sweets ended in the Railgun anime as well.
 * She and Saten Ruiko have cameos in both openings of the Toaru Majutsu no Index anime.
 * In several omake chapters, it is hinted 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 is the only named Level 1 in the whole To Aru Majutsu no Index history.
 * She has actually interacted with both Last Order and Misaka Mikoto, however she didn't notice any resemblance between the two.
