Level 6 Shift Project

The Level 6 Shift Plan (絶対能力者進化計画 (レベル6シフトけいかく)) is an experiment specifically created for Accelerator, the strongest Level 5 esper in Academy City, to achieve Level 6.

Concept and Creation

 * Main article:Radio Noise

According to Tree Diagram, only Accelerator can achieve Level 6, and with the implementation of the current curriculum, he can acheive Level 6 in 250 years. As such, seeing it was unfeasible to have Accelerator remain active for 250 years, the researchers were lead by Tree Diagram to a different method. Knowing that by training and combat scenarios, an esper such as pyrokinesis gain better accuracy, Tree Diagram has calculated that by preparing special battlefields for Accelerator, he can achieve Level 6. The fastest way for Accelerator to achieve this is to do battle with another Level 5, namely Misaka Mikoto—the Railgun. Tree Diagram determined that Accelerator killing Mikoto 128 times would allow him to achieve Level 6, however, since 128 Railguns cannot be created, the experiment determined that the reusage of the failed Radio Noise project for the convenient use of clones of Misaka Mikoto. Since the clones are of a level below the Original, it has been determined that the killing of 20,000 Radio Noise clones in 20,000 battlefields would be an apt substitute for Accelerator to achieve Level 6.

Background
It is unknown how long the experiments went on, however, seeing as Nunotaba Shinobu has talked to a clone wearing a winter uniform, and that Accelerator has killed the first clone who wore a summer uniform, one can assume that the experiments went for several months during the autmnal, winter or spring seasons—at least the preparations of the clones—before being stopped. Furthermore, several experiments have been executed within the premises of research facilities until being moved during May of the contemporary year.

In Accelerator's case, tired of the incessant imbeciles trying to pick a fight with him. Accelerator accepted the offer given to him to achieve level 6, determined that being stronger that only then will people stop fighting him. Upon the first experiment with Misaka 000001, Accelerator was reluctant at first to do battle with her, as he did not expect a clone of a level 5 to be so weak. Regardless, he put his doubts behind him as the researchers assured him that the clone will become stronger due to the Radio Noise network, as well as the fact that they are merely laboratory specimens. Despite this, Accelerator's subconscious lingered within him and tried to bring forth fear into the clones, trying to dissuade and communicate them throughout the experiments.

In May of the current year, the experiments moved to the outside and empty places. This is because of the requirements of the battlefield, as such experiments 1 to 9802 have been performed inside, while the remaining 10198 experiments would be dealt outside.

This precipitated Shinobu's plan in temporarily delaying the experiment with Bank cards in order for people uninvolved with the experiment to populate the places where the experiments would surely be held.

Known Participating Research Institutions
Because Level 6 is one of the main goals of Academy City, a large number of research institutes have invested in the project. After August 19th, the project was inherited by 183 institutions.

Sisters Arc

 * Main article:Sisters Arc

Level 6 Shift is the focal point of the Sisters Arc, since the reason for the current production of the clones are for Accelerator to kill. Misaka Mikoto is entangled with the experiment in an attempt to save her clones from certain death in the hands of Accelerator. Every attempt by Mikoto to stop the experiments are thwarted with one reason or another, Mikoto concludes that she needs to die in her first move against Accelerator, which would make the calculations of Tree Diagram wrong.

The experiment is stopped by the intervention of Kamijou Touma, who determined that if Accelerator were to be defeated by a level 0 like him, then the assumption of Accelerator being the strongest in Academy City would be incorrect, and the experiment would be stopped since it was based on that assumption of Accelerator being the strongest. Touma faces-off against Accelerator, where he realizes that Accelerator is physically weak and does not know how to streetfight since he defeats his oppopnents in one hit.

Though Touma was able to hit Accelerator several times with his right hand, despite being injured, he later gets put into a disadvantageous situation when Accelerator discovers how to create plasma, and attacking Touma with it from afar. With the help of Mikoto who urges her clones to help protect Touma, he is able to beat Accelerator and end the experiment.

Aftermath
After the experiment that Sisters were later distributed all around the world for readjustments in their bodies, since they were not expected to live long. Though the Level 6 Shift was halted, it was planned by Aleister Crowley – General Superintendent of Academy City – to fail all along since its inception, though he was unaware that it would be Touma who stop it.

The failure of the experiment gave Aleister an excuse to distribute the clones all around the world. This would create an antenna network for a basis of an AIM field umbrella that covers the globe. The resulting network of extended AIM field can then be upgraded into an Artificial Heaven that encompasses the world, creating another plane of existence that would upset the balance of current planes that all Magic is reliant on. Once the balance is broken the rules of Magic would no longer apply and any magicians using magic when the Artificial Heaven is activated would die from a backlash, and all buildings that have magical protection like the Vatican would collapse.

As for Accelerator, Aleister wants him to merge with the Imaginary Number Sector thus allowing him to achieve level 6.
