Development and writing

In June 2008, an anime television adaptation of Kazuma Kamachi's A Certain Magical Index was confirmed through a promotional sleeve wrapper of the light novel's 16th volume.[20] J.C.Staff was announced to be producing the series, while Hiroshi Nishikiori, who previously worked on Angelic Layer: Mobile Angel, Masanao Akahoshi, who wrote several episodes of Sky Girls, and Yuichi Tanaka were confirmed as director, series composition writer, and character animation designer, respectively.[21] Kazuma Miki, the light novel editor, wanted to make changes during the process of adapting the light novel into anime but felt a "double-edged sword" when thinking how to bring "Kamachi's color" to it and what fans would find interesting. Nishikiori laid out the concept of "following the original story" instead and aimed to have the viewers say so as well.[22] The series adapted the first to the sixth volume of the light novel.[23]

Casting

Atsushi Abe, Yuka Iguchi, Rina Satō, and Satomi Arai reprise their respective roles from the drama CD of the series, which was released in 2007,[24] as Toma Kamijo, Index, Mikoto Misaka, and Kuroko Shirai.[25] The main cast also includes Shizuka Itō as Kaori Kanzaki, Kishō Taniyama as Stiyl Magnus, Anri Katsu as Motoharu Tsuchimikado, Kimiko Koyama as Komoe Tsukuyomi, and Nobuhiko Okamoto as Accelerator.[26]

On August 25, 2012, Funimation announced the English dub cast for the series. These include Micah Solusod as Kamijo, Monica Rial as Index, Brittney Karbowski as Misaka, Alison Viktorin as Shirai, Morgan Garrett as Kanzaki, Robert McCollum as Magnus, Newton Pittman as Tsuchimikado, Jad Saxton as Tsukuyomi, and Austin Tindle as Accelerator.[27]

Music

I've Sound was selected to compose the music for the series due to Nishikiori's desire to have a "trance-like" soundtrack.[25] Mami Kawada performed the first opening theme music, which was used from episodes 1 to 16 (the DVD release updated the final use of it to episode 14), titled "PSI-Missing"[28] and the second one, which was used from episode 17 (episode 15 in the DVD release) onwards, titled "Masterpiece".[29] Iku performed the first ending theme music titled "Rimless ~Rimless World~" (Rimless 〜フチナシノセカイ〜)[28] and the second one, which was used from episode 20 onwards, titled "Oath ~Just a Little Once More~" (誓い言 〜スコシだけもう一度〜).[30]

Critical response

Ian Wolf of Anime UK News scored A Certain Magical Index 7 out of 10, praising the action scenes, voice acting, and animation quality while calling the music "OK".[54] Carlo Santos of Anime News Network graded the season 'C+', feeling that the "fight scenes, mind-bending story ideas, and unlikely plot twists" would delight fans but criticizing the "long-winded dialogue" and arrangement of story arcs that left "no sense of progression over the season".[55] Nicole MacLean of THEM Anime Reviews was critical of the show's characters, describing Toma Kamijo a "boring and ineffective lead", the bond between him and Index "staler and shallower" than Toradora! characters Ryuji Takasu and Taiga Aisaka, and Mikoto Misaka a "poorly-written character", unlike her appearance in A Certain Scientific Railgun series. She rated the season 2 out of 5 stars, stating that it "isn't a total loss, but... was a bit of a tedious series".[56]
