The narrative centers on Eren Yeager and Mikasa Ackerman as they begin their journey at Titan Jr. High, a unique school where humans and Titans share the same educational environment. Eren harbors a deep resentment towards the Titans due to a “traumatic” incident in middle school when the Colossal Titan devoured his lunch. This animosity drives Eren’s relentless quest to eliminate Titans from the world, which in turn makes it difficult for him to form friendships, causing concern for Mikasa.
