Tokyo Ghoul √A

The second season of the Tokyo Ghoul anime television series, titled Tokyo Ghoul √A, is produced by Pierrot, and directed by Shuhei Morita. The season aired from January to March 2015 on Tokyo MX, TVO, TVA, TVQ, MRO, BS Dlife and AT-X.

The season roughly adapts the second half of the Tokyo Ghoul manga, although, √A does not directly adapt everything from the manga. Rather, it mixes in the manga's content with an anime original story composition credited towards the author Sui Ishida. The season follows Ken Kaneki after he joins Aogiri Tree, as the group begins their battle against the CCG, who are trying to exterminate the ghoul organization.

The music is composed by Yutaka Yamada, who also produced the score for the first season. The opening theme for the season is "Munou" (無能, Munō; transl. "Incompetence") by österreich, and the ending theme is "Kisetsu wa Tsugitsugi Shinde Iku" (季節は次々死んでいく; transl. "The Seasons Die Out, One After Another") by amazarashi.

TC Entertainment released the series in Japan onto six volumes from March 27 to August 28, 2015. A complete set containing all twelve episodes was later released on September 30, 2016.

Madman Entertainment licensed the series in Australia and New Zealand, simulcasted the series on AnimeLab, and released the series on home video on July 6, 2016.
