Attack on Titan season 4

The fourth and final season of the Attack on Titan anime television series, titled Attack on Titan: The Final Season, was produced by MAPPA, chief directed by Jun Shishido, and directed by Yuichiro Hayashi, replacing Tetsurō Araki and Masashi Koizuka, respectively. Scriptwriter Hiroshi Seko fully took over the series composition from Yasuko Kobayashi, and Tomohiro Kishi replaced Kyōji Asano as character designer due to the series switching production studios. The season covers the "Marley" (chapters 91–106) and "War for Paradis" (chapters 107–139) arcs from the original manga by Hajime Isayama.

The season introduces Gabi Braun and Falco Grice, young Eldian Warrior candidates seeking to inherit Reiner's Armored Titan four years after the failed mission to reclaim the Founding Titan. While Marley plans to invade Paradis to strengthen their weakening military and retrieve the Founding Titan, the Survey Corps lay an attack in their homeland. As Marley and the Paradis forces go to war in Marley and the Shiganshina District, both sides sustain a heavy death toll while Gabi and Falco are forced to confront their internal tensions about the supposed "devils" of Paradis. In the second part of the season, aware of the global anti-Eldian sentiment resulting from Marleyan propaganda, Eren Jaeger preemptively targets the world outside of Paradis with the Rumbling, unleashing millions of Colossal-like Wall Titans in a widespread effort to kill all life beyond the island. In the third and fourth parts of the season, the Alliance led by members of the Survey Corps and Warrior Unit head to Marley in order to stop Eren's Founding Titan and end the Rumbling.
