Kuroyoru Umidori

Kuroyoru Umidori is a mysterious girl who apparently is connected to the dark side of Academy City. She poises as an antagonist in Shinyaku Toaru Majutsu no Index Light Novel Volume 01.

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.

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.

Chronology
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 autopiloted powered suits in after Shiage and Co., she attempts to finish off Accelerator with her cyborg enhancements. Accelerator merely "steps aside" and lets Shiage in the FiveOver defeats her.

Abilities
Her ability, "Bomber Lance", allows her to create lances of nitrogen which she can fire from her hands to attack her enemies with. She is one of the subjects from the 'May of Darkness' Project, just like Kinuhata. This 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.
