Childhood friend of Eren Yeager and Mikasa Ackerman and one of the graduates from the 104th Trainees Squad. Physically weak and often prone to self-doubt, Armin did not make it inside the Top 10 of the 104th. Nevertheless, his heart and high intelligence make him a very valuable soldier. Declaring that he'd rather be dead than be a burden, Armin joined the Scouting Legion despite Eren's protests. He shares Eren's dream of exploring the world outside the walls.
