Accelerator

**Accelerator**, also known as **Ippou Tsuukou**, **One-Way Road** and **Vector Change**, is one of the main characters from the *A Certain Magical Index* series.

## **Charactah Account**

Accelerator is the most powerful Level 5 Esper in Academy City, gifted with "Redirection", a type of power which lets him manipulate and control vectors of anything that his body comes into contact with. His most commonly seen use of this power is for defensive purposes, in which his entire body is surrounded by a thin invisible vector field, with manually configured filters for what is allowed to pass through (mostly air, as to allow him to breathe). This field will reverse the directional vector of anything that comes into contact with it, effectively acting as a reflector for any and all attacks. Accelerator may also choose to alter the magnitude value as well, to send the attack back at the attacker with x times the original force. His powers are also automatic, so anything that tries to hit him, regardless of whether he's aware or not, gets sent back where it came from hard.

Accelerator was part of an experiment called "Level 6 Shift", which ostensibly aims to turn him into the first Level 6 Esper by having him kill 20,000 of Mikoto's clone Sisters - only to be stopped dead by Touma. After the experiment was canceled and some soul searching, he pulls off a heel-face Turn and starts on his long and hard path to redemption by saving and protecting the very last Sister created - a little girl named "Last Order".

## **Trivia**

* Accelerator noticed after initiating a dust explosion in his fight with Touma that the temporary lack of oxygen almost killed him. Because of this, he realizes that even if he took on a direct blast from a nuclear weapon, he would then die from the lack of oxygen it caused. But in the novel, he subjects the idea that he could use an oxygen tank to remedy that situation, as some are made the size of hairspray bottles.
* Accelerator is the first known character who has managed to fill Index's stomach. Even when Maika cooks for Index, she only manages to fill 1/3 of Index's stomach according to Motoharu.
* Although Tree Diagram predicted that in a fight between Accelerator and Misaka Mikoto, she would die in 185 moves, the version of the SISTERS Arc in the Railgun manga shows that she would have been killed just by reflecting her strongest move, the Railgun, in 3 moves. Of course, this prediction is probably based on Accelerator's tendency to play with his opponents.
* Accelerator's voice actor, Okamoto Nobuhiko, won twice in the Annual Seiyuu awards for his role as Accelerator. He first won Best Male Rookie in 2008 for his role in Index, and he also won Best Supporting Actor in 2010 for Index II. These achievements were both pointed out in the Index-tan specials.
	+ The Seiyuu also later play the same type role as Karma Akabane which was thought to be strongest of all but later defeated by main protagonist, Nagisa on a duel at Assassination Classroom.
* When spoilers on Volume 20 was first released, there was the misconception that Accelerator had somehow managed split the country Russia into two halves. Later this is found to be false, stemming from a mistranslation in the narration at the part where Accelerator has just defeated Misaka Worst.
* Accelerator is shown to enjoy coffee as there are instances in the light novel of him buying/wanting to buy coffee. He enjoys the same brand of coffee that Touma likes (black coffee without sugar), and at least once (Volume 5 light novel, before encountering Last Order and after his defeat from Touma) he actually bought every coffee can left in the store, "foiling" Touma's attempt to buy coffee the next day (another possible joking nod to Touma's "misfortune") .
* Due to Accelerator's unusual introduction to Last Order and his equally unusual reaction to seeing her naked, not to mention their close relationship and the way he attracted Index's attention in Volume 12-13, fans have been joking that Accelerator might secretly be a lolicon. Misaka Worst lampshades this in New Testament Volume 1, because Accelerator is looking to help Fremea Seivelun.
* Like many other anime guys (and some girls), Accelerator entered Saimoe Contests and also won the champion title for the International Saimoe League 2015.
* The character Add from the Korean MMORPG *Elsword* bears a striking resemblance to Accelerator. Although looking similar to Add, KoG confirmed that they had no intention of giving Add the same personality as Accelerator, confirming the only thing similar between the two is the voice actor.
	+ One other possible trait that Add shares with Accelerator aside from his appearance and slightly close psychopathic personality is that one of his jobs/paths/classes is called Diabolic Esper, which is a reference to the Toaru world involving espers.
