Attack on Titan

Several hundred years ago, humans were nearly exterminated by titans.

Flash forward to the present and the city has not seen a titan in over 100 years. Teenage boy Eren and his foster sister Mikasa witness something horrific as the city walls are destroyed by a colossal titan that appears out of thin air.
