Misaka 13570

Misaka 13570 (ミサカ一三五七〇号) is a Sister, a clone of Misaka Mikoto, introduced in Souyaku Toaru Majutsu no Index.

Background
Not much is known about her, though as a clone she was most likely produced a few months prior to her introduction in the story.

Christmas Day Arc
On Christmas Day, Misaka 13570 was one of the four Sisters who made a move on the hospitalized Kamijou Touma, taking him from his bed to the bath in the amenities room, with Mikoto being embarrassed to find the four of them naked around him in the bath. After the clones were sent out of the room by Shokuhou Misaki, Mikoto prevented them making any further moves on Touma from the hospital's research sector.

Abilities
Like all of the Sisters, her ability is Radio Noise (欠陥電気 (レディオノイズ) ), a variant of the Electromaster (電撃使い（エレクトロマスター）) ability, and she is connected to the Misaka Network. Although not shown, she likely possesses similar equipment and training to her fellow Sisters.
