For more than a hundred years, the last remnants of humanity have lived inside a fortified city designed to protect them from a powerful race of man-eating giants known as Titans. We have been locked in a stalemate with the Titans unable to breach the walls of the city, but attempts at defeating them ending in death and disaster.

That was until the day the Colossal Titan appeared. Of the three walls that separated them from us, the first wall was breached and one-third of the population was killed. Countless lives and farms were lost, resulting in death upon the thousands.

It's been five years since that day, and while the future isn't bright, humanity has made a discovery that would forever change the tide in the war against the Titans. Humanity is not giving up.
