Kuroyoru Umidori

Kuroyoru Umidori (黒夜 海鳥) is an antagonist in the Toaru Majutsu no Index: New Testament series. She is a member of Freshmen and is a Level 4 esper.

Appearance
Her appearance is Loli-Goth, a white coat, and has black hair and yellow dye on the ends of her bangs, similar to Lessar's hairstyle, she usually wears a trench coat and is around 12 years of age. It should be noted that Kuroyoru's artificial arms are not "set" permanently into her, but instead are attachable parts which she connects to her back and controls at will, during her fight with Saiai she attached what was described as roughly "Hundreds, thousands of them".

Personality
She looks down on others as evident with her conversation with Kinuhata Saiai and treats anyone as disposable things. Accelerator remarked that talking to her was like having a conversation with his "old" self. She has a liking to stuffed doll dolphins and is always seen carrying one.

Background
She is one of the subjects from the Dark May Project, just like Kinuhata. However Kinuhata Saiai was treated as the star of the project, the "honor student" who perfectly followed the program, while Kuroyoru herself was thought of a delinquent who's rebellious attitude pushed the program to bankruptcy. This fact caused a slight fixation from Umidori to Saiai when they meet in New Testament. As to throw salt in the injury, during New Testament the Accelerator pointed out that Saiai was better suited for his cognitive patterns than her.

It should be noted that her rude demeanor and cruel personality are a side effect of the project, even to the point where her speech pattern is influenced by the data from the Accelerator.

Freshmen Arc

 * Main article:Freshmen Arc

In the first half of the attack by the "Freshmen" she makes sure that Hamazura Shiage and Accelerator meet up with assistance by Silver Cross Alpha. Later she meets with Accelerator, having a brief conversation about who she was and what are her plans before escaping. After sending in auto-piloted powered suits after Shiage and Co., she attempts to finish off Accelerator with her cyborg enhancements. Accelerator merely "steps aside" and lets Shiage & the FiveOver to deal with her, after the fight the Accelerator pointed out that since Kuroyoru's ability was so focused in the offensive factor, she was unsuited to use his cognitive pattens since the Accelerator used his ability defensibly and offensively with great proficiency, a comment which made Kuroyoru think of Kinuhata Saiai.

Homecoming Arc

 * Main article:Homecoming Arc

She passes out after attempting a final attack on Fremea only to be stopped by the return of Kamijou Touma. She is later carried to and restrained inside the bathroom of Touma's apartment. When Touma brings her some food, she displays her cyborg capabilities by disconnecting her left arm and striking with her right. Despite the seriousness Touma easily subdues her and treats her like a mixture of an appliance and child. The scene ends when Touma tries to see if Umidori has cyborg cat ears and she tries to keep him away.

Hawaii Invasion Arc

 * Main article:Hawaii Invasion Arc

Kuroyoru is seen traveling and unwillingly assisting the protagonists in their attempt to attack GREMLIN in Hawaii. In order to ensure safe journey and lower actions against, Birdway had everyone arrive in groups, the group Kuroyoru is with had Hamazura and Misaka Worst as her handler. With WORST's electrical powers, she could easily take control of Kuroyouru's cyborg parts which she clearly enjoyed doing. This is proven when WORST made Kuroyoru strike a pose while saying, "Trans☆form!!" also saying "Nyah nyah..."

Ichihanaran Festival Arc

 * Main article:Ichihanaran Festival Arc

Eve of the Festival
Hamazura Shiage conspires with Kinuhata Saiai in order to have her accompany Kuroyoru Umidori to the Hero's Cave, a dentist clinic in School District 7, after noticing that she has been avoiding chewing with her back teeth. He installs gum into the ports where her nitrogen lances are fired out of, knowing that she would resist.

Saiai takes Umidori there, much to her horror, indicating that Umidori is still a child, predictably, she tries to oppose Saiai using her Nitrogen lances, but due to Shiage's countermeasures, it does not work, and Saiai forcibly takes her into the clinic.

During the Festival
Apparently not caring that just yesterday she had her tooth pulled out, Umidori eats a taiyaki with cheese for the Ichihanaransai, and ends up at a a pedestrian bridge. Minding her own business, Misaka Worst suddenly comes upon her.

Since Misaka Worst was an electromaster, and worse off, Umidori's ejection ports for her powers have been cut off, she had no way of defending herself from her. Misaka Worst catches Umidori as she eats a taiyaki with cheese, and comments on how she went for the cotton candy instead, lamenting on how the ones made by kids are poorly made. Umidori seeing her casual comment, tells her that they are not friends. Misaka Worst comments on how since both of them have no friends, they should get along together. Umidori references it as being in a pathetic girl group, and tells her not to put her in the same category as her. As Misaka Worst continues to tease her to "deepen" their friendship, they are visited upon by an unlikely person—Misaka 10032.

Umidori quickly then points out that she now has a friend for her, to which Misaka Worst says that she hates clean people without that nasty look in their eye like her. Umidori comments on how everything she does tells her that she has no intention of being her friend, to which she ignores. Misaka Worst then tries to open a conversation with Misaka 10032, regarding of her current actions. Misaka 10032 states that she removed her shoes to rest her feet while she took a break on a bench, but a black cat climb inside one. Still now, the cat remains inside her shoe. Seeing this, Misaka Worst suggests that she should drag it out with an iron claw, to which Misaka 10032 does not take lightly.

Misaka Worst states that three is not enough, and asks if there are others with nothing to do. Coincidentally, Saiai manages to pass by and forms a disgusted expression after coming them, especially at Umidori. Misaka Worst, seeing her, agrees that she has that nasty look on her face, seeing at they are ken to the ways of the dark side. Seeing them all, Saiai then asks if they are a bunch of villains trying to create their own faction. Misaka Worst comments on how with dark people like them around, she could enjoy the Ichihanaransai honestly without holding back.

ESP ability
Her ability, Bomber Lance (窒素爆槍 (ボンバーランス) ), allows her to create lances of nitrogen which she can fire from her hands to attack her enemies with. Being from the Dark May Project just like Kinuhata accounts for the similarities between their abilities, though Kuroyoru's ability is more offensive based compared to Saiai's defensive. To make up for the difference in power that she can only use her ability with her hands, she implanted dozens of cyborg arms into herself, so that her personal reality treats those arms as her own and she can use her ability with those arms. Kamachi Kazuma commented on how Kuroyoru's battle tactics seemed to mirror the idea of "who is stronger, a level 5 or a thousand level 4?" It should be noted that it doesn't matter how many hands Umidori uses, the power source is still one individual and thus, extensive usage can become quite straining to her.

Cyborg enhancements
Kuroyoru can use her robotic arms for several purposes and not only to shoot her ability. When she was presented against the surprise attack from the FiveOver Kuroyoru entangled herself in her arms and used them as a protective shell, though the defensive shield proved to be of no use against attacks that can match Tokiwadai's Railgun. Kuroyoru can also not only use her arms to fire "normal sized" air lances if she just uses each arm individually, but can as well combine the efforts of several arms in order to create a giant air lances of greater power than the normal ones, furthermore since the arms are cyborgs she can input data into them, such as when she added Kihara Amata's battle data, which would have allowed her to exploit the blind spot in Accelerator's Vector Shield if they would have fought.

Kuroyoru has stated herself that besides her arms she basically the same as a human even though she can regulate to some extent her own metabolism or bring herself into a suspended animation state. She also disclosed that since her body has been tuned up with "high precision equipment" she needs maintenance quite often

Character Art Designs
First draft of her design had Umidori with a dark coat, but was eventually replaced with a white one. Umidori was designed as a complete opposite to Index and Last Order, someone who does not incite the feeling that she needs to be protected.
