Misaka 10046, one of roughly 20,000 Mikoto Misaka clones engineered for the Level 6 Shift Project—a plan to elevate Accelerator by forcing him to slaughter the Sisters—remains in Academy City post-experiment for adjustments. Identical to her siblings, she sports Tokiwadai Middle School’s uniform, electromagnetic-perception goggles, and blue-striped panties, with certain media distinguishing her through subtly altered eye designs. Initially mirroring the Sisters’ emotionless disposition, she gradually exhibits heightened individuality, expressing fear, hesitation, and cowardice under threat. This emotional evolution includes implied affinities toward Accelerator, diverging from her peers’ preference for Kamijou Touma. During the Necromancer Arc, she intervenes to shield a fleeing mother and daughter from a Disciplinary Action (DA) operative at Heaven Canceller’s Hospital. Though trained in combat and armed with Level 3 electromastery, her assault falters against the operative’s insulated gear, resulting in her capture. Transported to a DA base, she becomes pivotal to clashes involving Accelerator, Esther Rosenthal, and the cleanup squad Scavenger. A coalition including Accelerator rescues her, battling DA’s reanimated corpses and necromancy-powered Coffin mechs. In a crossover incident, she enters the ALICE dimension, encountering Sen no Rikyu, a tea master resembling an acquaintance from her world. Intrigued by his teachings, she vies with Last Order for his attention until their rivalry escalates into a brawl. Both abandon plans to accompany Rikyu upon realizing the journey’s duration, returning home after observing Accelerator’s battles. Her arsenal includes Sister-standard gear like the Metal Eater MX sniper rifle and Toy Soldier assault rifle, enhanced by hacking prowess to control machinery. She improvises weapons, such as a crowbar against zombies, while maintaining the Sisters’ third-person speech pattern. Despite growing emotional complexity, her portrayal remains consistent across media, underscoring the clones’ struggle to reconcile artificial origins with burgeoning selfhood.
