Accelerator's History
Accelerator (�?�?��??�?�?��?��?��?��?��?��?� Ippō Tsūkō (Akuserar�?ta)?, lit. "One-Way Road") is the 1st-ranked Level 5 and the strongest esper currently residing in Academy City.
He is the second protagonist of the Science Side in the Toaru Majutsu no Index series. First appearing chronologically in Toaru Majutsu no Index as an antagonist, he later becomes the male protagonist of the Science Side after Kamijou Touma defeated him. His journey to a more "heroic" role in the story progresses after meeting and saving Last Order and is forced into an ironic twist of fate where his life now depends on the Sisters, clones he previously killed by the thousands. He is also a major antagonistic character in Toaru Kagaku no Railgun and the protagonist of Toaru Kagaku no Accelerator.
In his role as a protagonist, he is forced to deal with the cruel Dark Side of Academy City and the secret conspiracies surrounding it. As the most powerful esper of Academy City, his existence and powers are tied to the plans of Aleister Crowley, the founder of Academy City, alongside Kamijou Touma.
Much of Accelerator's past is unknown, but he mentioned that he once had a "normal name" which has yet to be revealed, and most likely never will, as Accelerator himself forgot it. The novels state that his last name consists of two kanji and his first name three, yet his name had no real meaning in it.[4]
Ever since taking the Power Curriculum Program, and realizing his powers, Accelerator was sent to a "special class", most likely, the Special Ability Institute,[5] and spent much of his childhood there until he turned nine-years-old, before being moved into another special class. Both of these had him as the only student. It can be presumed that this occurred before the incident involving the military.[6]
When Accelerator was a child, he couldn't fit in with the other children due to his powers, harming those that tried to get close to him. Around at the age of ten, a particular incident with children escalated with Academy City being deployed against him, and he later "gave up", and was sent to a special class.[4] This has made him something of a loner and distrustful towards other people. After some time, Accelerator was discovered by Kihara Amata, who trained him on how to control his powers and influenced him enough for Accelerator to adopt his personality. It can be assumed that the Dark May Project started after Accelerator acquired the cool personality he now has from Amata.
Accelerator's ability made him the subject of an experiment attempting to create the first Level 6 esper; according to the city's best supercomputer, Tree Diagram, this feat could only be achieved by killing Misaka Mikoto, the 'Railgun', 128 times. However, because it was impossible to create 128 of these 'railguns', due to the 'Level 5 Mass Production Plan' only being capable of producing a sub-standard clone of Mikoto at a power of Level 2-3, a substitute plan was arranged where Accelerator would have to kill 20,000 Misaka clones in a variety of methods. He willingly joins the experiment to gain a reputation as the most powerful and feared esper so that no one would be foolish enough to challenge him ever again. By the beginning of the Sisters Arc (index), Accelerator has already killed the first 10,030 Misaka Clones and during the course of the arc, kills clone 10,031 before the experiment is ultimately stopped.
Later it is revealed that he originally wanted this reputation simply so that no one would ever get hurt trying to attack him, resulting in their own destruction, though as he went deeper into Academy City's dark side his goals slowly became more and more twisted.
