Set in a distant, post-apocalyptic future, Nier Automata Ver1.1a follows the story of 2B, an elite combat android, and 9S, an inquisitive scanner model, as they navigate a desolate Earth overrun by hostile machines. These androids, created by humans who fled the planet long ago, engage in a relentless war to reclaim their home for humanity. Yet, as they battle, they uncover hidden truths about their creators, the enemy, and themselves—truths that blur the lines between machine and man, purpose and despair. Through striking visuals and existential storytelling, the anime adaptation delves into themes of identity, duty, and the meaning of life, capturing the melancholic beauty and philosophical depth that define the Nier universe.
