Kuroyoru Umidori

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

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 Saiai. 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.
