Attack on Titan: Beyond the Sea, Not Freedom

Destiny or freedom? Take command of the Founding Titan and unleash the Rumbling toward the other side.

Kate Lee·
2200

You stand at the end of the Titans. As Eren Yeager, you have already seen the vista of hell through memories of the future. This is a cruel world. In order to push open the door called "freedom," you must put on the demon's mask with your own hands.

In the ultimate gamble between Paradis Island and the Marley Empire, the bonds of former comrades are tearing apart, the gun barrels of revenge are raised, and the causal chain of history is violently trembling. "Even after death, even past the other side, this is the story we started ourselves." Dedicate your heart, and make choices you will not regret.
