Attack on Titan (Japanese: 進撃の巨人, Hepburn: Shingeki no Kyojin, lit. “The Advancing Giant[s]”) is a Japanese manga series written and illustrated by Hajime Isayama. It is set in a world where humanity lives within cities surrounded by enormous walls that protect them from gigantic man-eating humanoids referred to as Titans; the story follows Eren Yeager, who vows to retake the world after a Titan brings about the destruction of his home town and the death of his mother. Attack on Titan has been serialized in Kodansha‘s monthly Bessatsu Shōnen Magazine since September 2009, and collected into 32 tankōbon volumes as of September 2020.
An anime television series adapting the manga was produced by Wit Studio (seasons 1–3) and MAPPA (season 4). A 25-episode first season was broadcast from April to September 2013, followed by a 12-episode second season broadcast from April to June 2017. A 22-episode third season was broadcast in two parts, with the first 12 episodes airing from July to October 2018 and the last 10 episodes airing from April to July 2019. A fourth and final season is scheduled to premiere in December 2020.
Attack on Titan has become a critical and commercial success. As of December 2019, the manga has over 100 million tankōbon copies in print worldwide, making it one of the best-selling manga series of all time. It has won several awards, including the Kodansha Manga Award, the Micheluzzi Award, and Harvey Award. The anime series has also been well received by critics, with the first three seasons being met with praise for their story, animation, music, and voice acting, thus boosting the series’ popularity in U.S. and Asia. Although it has gained significant fame and popularity in Japan’s neighboring countries, political interpretations of the series have caused controversies in China and South Korea.
