Eren Yeager



The protagonist of the story, Eren Jaeger was from a town of the outer most wall, Maria. His closest friends Mikasa and Armin have both joined the Scouting Legion with him after having their town annihilated by the titans.

Background
When Eren was a child, he saved Mikasa from being killed when visiting her home with his father. Three men - killers of her parents - were in her house. Killing two of them, he was caught off guard by the third who proceeded to strangle him. With superhuman strength, Mikasa jumps forward at the man after realizing that it is a "kill or be killed" life they are living. As Eren's father finds them surprisingly safe and unharmed, Eren gives Mikasa the sentimental scarf she always wears, and declared her a part of his family.

With the invasion of Wall Maria after the Colossal Titan makes a path, Eren discovers the horrors of the life he is living that sets the motion for his future. Seeing the destruction of his town, mindless titans slaughtering humans, and his own mother being eaten alive as he was helpless to save her, Eren remarks that the life humans live is controlled entirely at the mercy of the titans and are nothing more than cattle. Being dragged away by a local Stationary Troop, Hanneth, Eren swears to kill every single titan in existence with tears of frustration and hatred.
