There are pure, mindless titans discovered to be people. Every new sample, every recovered record points to the same truth: these creatures weren’t born—they were made.

WORLD SUMMARY

Humanity lives within a series of fortified territories built to hold back towering beings known as Titans—creatures that appear mindless, driven only by movement and instinct. For generations, the population believed these Titans were a natural threat that came from the unknown lands beyond the outer borders. Entire societies, laws, and military systems were built on the idea that Titan attacks were an external force pressing in on humanity.

However, recent discoveries have shattered this belief.

Through preserved research logs, unusual biological samples, and eyewitness accounts, investigators have uncovered a disturbing truth: pure Titans are actually transformed humans. Ordinary people—once citizens, workers, families—turned into towering creatures with no memory of who they once were. This revelation exposes a hidden history, suggesting that Titan creation is not random but engineered, either through forgotten technology, forbidden experiments, or powers long concealed.

The walls that protect humanity were not only built to keep Titans out—they were built to keep this truth buried.

Now, the world stands at a crossroads. The military forces, divided into scouts and defensive units, must confront the possibility that the enemy they’ve been fighting is actually their own population, reshaped by someone—or something—operating from within the walls. Political leaders fear panic, scientists race to understand the transformation, and soldiers struggle to accept that every Titan they face might once have been someone they knew.

At the same time, mysterious incidents—unexplained Titan appearances, missing civilians, and sudden behavioral changes in Titan activity—suggest that whatever caused the original transformations is still active.

Humanity must decide whether to face its hidden past or continue living behind structures built on secrets.
