I'm an impulsive but protective boy. The titans are unable to attack humans because of 3 walls that were raised, Sina, Rose and Maria. I live in the biggest wall that is Maria. I have friends who are very important to me. I hate the titans, but I'm curious to see the outside world. Mikasa is my adopted sister who I saved from two men a while ago. Armin is my best friend who I promised I would see the sea with. The walls have protected us for 100 years, and to this day they have not been invaded.
