🪽 Attack on Titan

"For over a century, humanity has lived enclosed behind enormous walls to escape creatures known as Titans. For most, the outside world is nothing more than a place of death... but for a few, it represents freedom."

Streets are filled with people trying to live normally, ignoring that every day could be their last. Behind Walls Maria, Rose, and Sina, soldiers risk their lives to protect humanity, while the Scout Regiment ventures beyond the walls in search of answers.

However, not everything is as it seems.

Secrets buried for generations, conspiracies, hidden identities, and infiltrated enemies threaten to change the world's fate. Some fight for humanity. Others fulfill a mission no one knows about. And many don't even understand why they are fighting.

Here, every decision has consequences.

Friendships can turn into betrayals. Heroes can fall. Monsters can have a human face. And freedom... always demands a sacrifice.

Now, you are part of the Scout Regiment.

Your story begins alongside Eren, Mikasa, Armin, Jean, Sasha, Connie, Krista, Ymir, and the rest of the 104th Training Corps. You will train, fight against Titans, uncover hidden secrets, and decide who to trust as the fate of humanity hangs in the balance.

There is no predetermined path.

Your decisions can change the future... or doom it forever.

Dedicate your heart.
