Toaru Kagaku no Railgun (anime)

Toaru Kagaku no Railgun (とある科学の超電磁砲（レールガン）), translated as A Certain Scientific Railgun, is the anime series adaptation of the Toaru Kagaku no Railgun manga series by Fuyukawa Motoi. The series was produced by J.C. Staff between 2009 and 2013, and was directed by Nagai Tatsuyuki and written by Minakami Seishi (replaced by Yasukawa Shogo in Season 3), with music by Iuchi Maiko.

The anime series is composed of two 24-episode seasons, and is set in the same universe as the Toaru Majutsu no Index light novel series, although with a focus towards one of the seven Level 5s in Academy City, Misaka Mikoto. On October 7th 2018, a third season was announced. Entitled Toaru Kagaku no Railgun T, it began airing on January 10th 2020 for a 25 episode run.

Plot
Like in the original manga, the Toaru Kagaku no Railgun anime series serves as a supplement to the Toaru Majutsu no Index anime, focusing more on life in Academy City.

Misaka Mikoto is known by many as the ranked-third Level 5, the highest attainable level of an esper, and a role model to many students in Academy City, especially in Tokiwadai Middle School, where she studies. However, a little-known fact is that Mikoto is also like most of the population of students in the city and is far from the role model figure many assume her for. The series documents Mikoto's various exploits within the city together with her devoted roommate Shirai Kuroko and her friends Saten Ruiko and Uiharu Kazari.

The first season focuses on a mysterious sound file that is rumored to allow its listeners to gain esper levels, as well as the teacher that develops the file. The second season coincides with a substantial arc in the Toaru Majutsu no Index light novels which involves an experiment that used Mikoto's DNA map to create clones of herself which are later slaughtered to give way for an attempt to produce the first Level 6 in Academy City. Both seasons feature anime-original story arcs, with the first season dealing with mysterious earthquakes, and the second season centering around a girl created for an experiment by an organization who seeks to rebel against the current methods of developing esper powers. The third season takes place during Academy City's annual sports festival, featuring the science-side incidents that occurred in parallel to the events shown in Index, with Mikoto's rival Level 5 at Tokiwadai being a key player.
