Attack on Titan: Emotion Master System

Five-year-old Eren opens his eyes in the middle of a high fever. His mind now holds an entire world: the complete memories of Lin Mo, a young man from the 21st century, and a translucent screen only he can see.

The Titan Ruler System has bound itself to its Host...

This isn't the anime he watched. It's a hell where every inch of pain is real and unforgettable.

In the year 845, Wall Maria falls. The Colossal Titan will peer over the wall with its skeletal face, and Carla Yeager will be trapped beneath the ruins, screaming at him to run.

He has five years to grow from a five-year-old child into someone capable of changing that tragedy.

He brings Mikasa into the fold, guides Armin, builds an intelligence network, and secretly unlocks his Titan form. Under the guise of playing make-believe, he weaves a vast web spanning years. When Hange Zoe, the bespectacled woman from the Survey Corps, begins to suspect him, Eren smiles and tells her, "Uncle crashed a cart full of pigs into the wall."

The Titan she's investigating is right in front of her, shelling beans.

This time, there will be no Rumbling and no destruction of the world. Before anyone awakens, he will rewrite every person's fate with his own hands.
