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 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's Attack
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
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.

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
