(W/A/CA) Isayama Hajime. Humankind is down to just a few thousand people who live in a city surrounded by three concentric walls. The walls protect them from their enemies* the ravenous giants known as the Titans. The Titans appear to have only one purpose: to consume humanity. For one hundred years* what's left of mankind has lived in the city on earth* protected by walls that tower over even the Titans. Humanity has become complacent* but Eren Jaeger has had enough. Jarger and his friends are determined to survive. But everything about their situation is a mystery that only becomes more complicated the more they learn.
