Toaru Kagaku no Railgun (manga)

Toaru Kagaku no Railgun (とある科学の超電磁砲（レールガン）) or A Certain Scientific Railgun is the second manga series that is based off the Toaru Majutsu no Index franchise. The Toaru Kagaku no Railgun manga is an original side story written by Kamachi Kazuma and illustrated by Fuyukawa Motoi.

The Railgun manga series is released as a monthly manga in the Dengeki Daioh magazine since February 2007, and currently has twelve tankoubon volumes released.

The manga series has been adapted into two 24-episode anime series based on the first six volumes of the manga from October 2009 to March 2010, followed by an OVA released on October 2010. A sequel to the anime series entitled Toaru Kagaku no Railgun S was green-lit, which was confirmed to cover the Sisters Arc in the original manga.

Plot
Diverging from the plot of Index, Toaru Kagaku no Railgun focuses more on Academy City and the third of seven Level 5 espers named Misaka Mikoto.

Misaka Mikoto, despite being part of the most powerful espers in Academy City, also has a more carefree side to her life. She has to fend off constant "love attacks" from devoted friend and roommate Shirai Kuroko but despite of being the Ace of Tokiwadai Middle School she still acts like a normal student as in nobody is better than the other. However, with various problems arising in Academy City — both noticeable and out from plain sight — she moves as Academy City's unseen savior, using her powers to save people, loved ones and strangers alike.

Development
The concept used in Toaru Kagaku no Railgun began when the future editor (Ogino Kentarou) of Railgun made a request to Miki Kazuma, Kamachi Kazuma's editor, on how he wanted to have an Index manga in Dengeki Daioh. Due to the fact that the Index manga was already serialized in Monthly Shōnen Gangan, the editor asked for a Daioh to have one for the science side, specifically that of Misaka Mikoto.

The idea was well received by Miki, and after a general idea was drafted, the producers asked Kazuma to write the original concept of it. Kamachi Kazuma, at that point, was told that the manga would be using Academy City as a primary state, as such, he wrote the original draft with Shirai Kuroko as the protagonist, feeling that Mikoto was too powerful a character from who he could make an an entertaining manga. He was later corrected, and was asked to use Mikoto instead, despite having written "quite a bit". Because of this, he was forced to rethink everything from the ground up in order to use. It is unknown what would have become of the side story had Kuroko been accepted as the protagonist.

Motoi was later called up to be the artist of the manga, and started serialization in the April issue of Dengeki Daioh on March 2007. The first volume was later released on November 10, 2007.

Overseas Release
Seven Seas Entertainment licensed the manga in North America and began releasing the series in North America starting with the first volume on June 2011. Like the rest of the printed series by Kamachi, the manga is distributed by Kadokawa Taiwan for the Chinese market, with the first volume being released on April 29, 2009.
