Marionette (洗脳能力(マリオネッテ) lit. Brainwash ability (Marionette)?) is an ability that is referenced by Kamijou Touma during his attempt at convincing Kanzaki Kaori to rely on the Science Side in order to help Index, who, at that time, required her memory to be erased else she would die. Since it is apparently related to the manipulation of the mind to have a person do thing forcefully, as well as the fact that it is called a brainwashing ability, Shokuhou Misaki has shown abilities similar to this.
