The Accelerator is a major character featured in the Toaru series of light novels authored by Kazuma Kamachi. Introduced as an antagonist in Toaru Majutsu no Index, he eventually became one of the series' main protagonists alongside Touma Kamijou and Shiage Hamazura, and would later get his own spin-off series titled Toaru Kagaku no Accelerator.

The albino esper is the most popular male character in the series. He is best known as a powerful force in the International Saimoe League, partly due to Misaka's influence in the contest. He was the champion of the first Main Tournament for males which occurred in 2015; prior to that he reached the final of the 2013 male Exhibition Tournament, losing to Hyouka's Houtarou Oreki.

Only one gem award has been given to him --- the 2015 sapphire crown --- as a result of securing the first seed of that year's playoffs due to finishing the regular season with the highest seeding score.

Elsewhere, the white-haired psychic has seen several minor contest victories held mostly within Chinese websites, particularly Bilibili and Tieba Baidu. Accel also remains the most recognizable Raildex male in the Western-majority r/anime contests, despite the series' historically mediocre performance there (oustide BG3 winner Mikoto).

ISML Profile Flavor Text[edit | edit source]

Written by Momento10 (assumed)

The strongest person in the world is in search of more power… or is he?

Accelerator, a boy in possession of a supernatural power which basically makes him invincible, is offered a chance to grow even stronger through participation in a certain experiment. The idea is simple: he just needs to defeat a certain number of clones who get progressively difficult to defeat. Usually, Accelerator would rather do things his way than trust any of these scientists and be ordered around like a lab rat. Besides, he already considers himself the strongest in the world; who cares about some ridiculous experiment? But the potential extra boost in power is tempting and he decides to give things a try… not quite aware of the endless bloody spiral the experiment will drag him into.

Accelerator thrives on being the best, strong enough to take on any thugs who do not know his name and crush those who look down on him. Just his name should be enough to send even common people scurrying away from him. But as he reaches closer to his goal of becoming the strongest, Accelerator shows hints of the loneness haunting him. Accelerator is resolved to shrug those feelings aside, but climbing to the top by himself might be a lot more lonesome than he thought.

Still, Accelerator moves on, believing that this is the only way to achieve the strength he wanted. While it might look like there is nothing that could stop his descent into darkness, a glimmer of hope might be born from the very same experiment leading Accelerator astray. Even for the most powerful person in the world, the warmth of another’s heart might be enough to remind them where true strength comes from.

Character Profile[edit | edit source]

Etymology[edit | edit source]

His Japanese name 一方通行 (Ippōtsūkō) literally means "one-way", a reference to the character's ability Vector Change, a power that automatically allows the psychic to change the directions of anything he touches. Because of this ability, most projectiles and explosives are almost always redirected away from him the moment they touch his body, rendering them ineffective.

The international name Accelerator also references Vector Change, and indirectly references particle accelerators as well, because his ability also affects particles such as light, sound, and electricity. The name "Accelerator" is an alias; he has a real name, which is not yet revealed in the story.
