Eren Jaeger is alone. He is the only one left in the orphanage who's over twelve years old, and is the most hated student in his high school. He spends his days being tortured by his classmates, pretending to understand his best friend's, Armin Arlert's, genius lectures, and is consumed by depression. Until the day he meets a new girl named Mikasa Ackerman, the love of his life. As the two become closer and closer, Mikasa is introduced to his world. A world of pain, hatred, and fear. A cruel world, where the only way to live is to fight.
