Kidera Minori

Kidera Minori (木寺実莉) is a minor character introduced in the Toaru Kagaku no Accelerator anime. She is part of a group which attempts to steal Accelerator's genetic information.

Appearance
Minori is a tall high school girl, taller than Accelerator. She wears her black hair in a side tail and straight bangs. She presumably wears her high school uniform, a black skirt, white shirt with red ribbon, and a gray cardigan. She has yellow eyes and wears glasses.

Personality
She is soft-spoken and is often seen in the sidelines alongside Nakahara Hiromi in a supporting role while Takada Youko do all the work. She is loyal to Youko despite her misgivings with her actions. Still, she cares for both her accomplices. She worries for Hiromi's well-being after being knocked out while they are on the run. And later, she tries protecting her from Accelerator himself after her easy despite being scared.

Minori calls Youko Yo-chan.

Toaru Kagaku no Accelerator
She accompanies Takada Youko and Nakahara Hiromi as they attack a certain hospital, targeting Accelerator in order to get his genetic material. Though Youko does all the work, Minori's role was to prevent people from getting near them using her ability and taking advantage of the nitrogen that Youko's weapon releases.

After Hiromi is taken out, she is forced to take the last remaining ammunition for Youko's weapon he had and later goes on a run with her underground. She questions Youko of her plans and Minori's well-being. Youko plays down her concerns as she says Accelerator's genetic material will make them rich and enable to get Hiromi out of jail. She later questions why Youko is planting explosives on the pillars of the underground, to which Youko says is to help them escape. They are then joined by Accelerator, who makes short work of not only Youko's traps but of Youko herself. Accelerator carefully explains how Youko's weapon works as well as Minori's ability. Accelerator pushes a current of air to force Minori to release Last Order's bag of cookies (that was Accelerator's blood spilled on earlier) and fly to him.

Youko tries one final attack but Accelerator easily manipulates the ultra-high-pressure water blade to dismantle the weapon. Accelerator later gets close to her and kicks her. Before Accelerator can finish the job, Minori gets in-between them, telling Accelerator that she'll have to take her own if he wants to keep fighting. Seeing her frightened look, Accelerator spares them, giving the girl a simple flick on the forehead as she collapses to her knees in bemusement. Accelerator lectures Minori that if she really cared enough to risk her life for her then she should have stopped her before it got to that point.

Abilities
Her ability name and level is unknown, but Accelerator calls it Aero Separator (エアロセパレータ). In a range of 3 meters, Minori can control the concentration of gases in the air. This ability allows her to protect herself and her friends from the nitrogen gas that's released from Youko's weapon by maintaining enough breathable air around them.
