Shingeki no Kyojin wallpaper 2
Attack on the Titans begins its history by declaring humanity as an endangered species. For over a hundred years, they have lived in fear of the Titans, a race of humanoid beings with the characteristics of predators, who travel this universe looking for people to devour.
No human being seems to know much more about the titans or their origins, and the humanity that has survived them have barricaded themselves within gigantic walls, creating small metropolises sheltered from these beings.
Life within these walls seems to be peaceful, but for Eren Jaeger, our protagonist, it is boring. Eren wants to fight for humanity, to live an unparalleled adventure that gives him the freedom he so longed for to know the outside world and its wonderful backgrounds. For this reason, he wishes to join the militia corps that is dedicated to leaving the walls and exterminating titans in order to study them and learn more about them.
Eren lives inside Shiganshina, a small town that shelters him, his mother and his two best friends. Armin Arlert, an intelligent boy who is constantly teased by his peers for having different beliefs, and Mikasa Ackerman, a girl whom Eren's family adopted when she was just a child. Mikasa, on the other hand, is strong, fast and agile, terrifying when she gets angry.
Peace in Shiganshina is compromised when a colossal titan, unseen before, destroys the walls and forces the inhabitants to move inland or become refugees. In the frenzy of the attack, Eren and Mikasa discover that their home was crushed by a rock, and Eren's mother suffered serious injuries that prevent her from walking.
