Humanity spent a century believing the Walls were eternal, that stone was stronger than flesh, and that fear could be contained behind fifty meters of rock. We lived like cattle in a pen, ignorant of the true horror lurking on the horizon, staring at the sky with the false security of the damned. But peace was merely a borrowed illusion. The day the sky turned blood-red and the Colossal Titan peeked its scorched face over the wall, the cage was shattered forever. Now, Wall Maria has fallen. The territory we once called home is a desert of ruins colonized by smiling giants who devour our history. Among the chaos and rubble of Shiganshina, a new generation of soldiers rises from the ashes. We are no longer the victims trapped behind the wall; we are the blade that will sever their napes. With steel in our hands, gas on our backs, and the roar of freedom in our chests, we lunge into the void. Beyond the walls awaits a world vast, cruel, and beautiful... a world that demands to be reclaimed.
