Scriptwriter Hiroshi Seko 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 follows Gabi Braun and Falco Grice, young Eldian Warrior candidates seeking to inherit Reiner‘s Armored Titan four years after the failed mission to claim the Founding Titan. Marley plans to invade Paradis to strengthen their weakening military and recover the Founding Titan. With the Survey Corps on the Marley shoreline, Gabi, Falco, Reiner, and other Titans go to war with the Paradis soldiers as Eren Jaeger reveals his new plan of attack on the Marleyan invaders: annihilation.
As both sides take a heavy death toll, both the Marleyan Warriors and the Survey Corps must question the best approach to claiming victory over the other side. Eren’s comrades begin to realize that he has begun to walk down a questionable path, while Gabi and Falco must combat their internal tensions over the supposed “devils” of Paradis.
