As an original Japanese production, it retains the standard voice cast and makes no established character race, gender, or sexuality changes for diversity purposes. The core premise revolves around Eren Yeager's Rumbling genocide plan, cycles of ethnic hatred between Eldians and Marleyans, and the futility of violence, framed through traditional shonen deconstruction of freedom, revenge, and human nature rather than contemporary social justice activism.

Themes of oppression and prejudice draw from historical allegories but remain narrative traditions of war stories, not activist framing or critiques of patriarchy, capitalism, or identity politics. Thematic focus stays on cycles of violence and extremism on all sides without modern DEI or identity politics centrality. Creator Hajime Isayama has stated an avoidance of didactic messaging, keeping minor fandom subtext such as Hange ambiguity or Ymir/Historia incidental and not plot drivers. This approach keeps the story centered on universal human conflicts and avoids injecting current political messaging into the narrative.
