The transition was violent. One moment, Ken was standing in the shadow of Wall Maria, the air thick with the smell of livestock and impending dread. The next, the world dissolved into streaks of white ink.
Ken didn't want to see the walls fall. He didn't want to hear the screams of Shiganshina or watch Eren's mother die. Not yet. He needed to see what they were fighting for first. He needed to see the "Hope" at the end of the tunnel so he knew exactly what to protect.
He opened the Digital Book, his fingers dancing across the glowing screen.
"Skip to the end of the prologue," Ken muttered. "Timeline shift: Year 851. Location: The Edge of Paradise."
He gripped the edges of the book as the reality around him buckled. The Authority of Erasure hummed in his veins, not deleting a person this time, but erasing the time between the tragedy and the triumph.
SWISH—!
The oppressive stone walls vanished. The smell of blood and old hay was replaced by something Ken had only ever read about in the manga: the sharp, stinging scent of salt.
Ken blinked, his blue eyes adjusting to the blinding sunlight reflecting off the water. He was standing on a high sand dune, his black jazz pants catching the sea breeze. Below him, the blue expanse of the ocean stretched out forever—the "Big Water" that Armin had always dreamed of.
And there they were.
A small group of teenagers, wearing their scout uniforms, were standing at the shoreline. They looked so small against the infinite blue.
"It's real..." a voice drifted up the dune. It was Armin, his voice trembling with a mixture of joy and disbelief. He was holding a seashell like it was a holy relic. "Eren! Look! It's exactly like the book said! It's all salt!"
Ken watched from the shadows of his hoodie, a small, sad smile on his face. He saw Sasha and Connie splashing each other, their laughter ringing out over the sound of the waves. He saw Mikasa, her red scarf tucked away, looking at the horizon with a rare moment of peace in her eyes.
Then, there was Eren.
Eren Yeager stood knee-deep in the surf, his long hair blowing in the wind. But he wasn't laughing. He was pointing a single, trembling finger toward the horizon—toward the enemies he knew were waiting across the sea.
"Hey," Ken whispered to himself, his blue eyes glowing. "Don't point at the enemies yet, Eren. Just for today... just look at the water."
Eren's finger remained frozen, pointing toward the edge of the world. "If we kill all our enemies over there... will we finally be free?"
The weight of his words hung heavy in the salt-crusted air. The peace of the moment was beginning to fracture under the pressure of the future.
Ken, watching from the dune, knew he couldn't let the silence last. He tapped the glowing glass of his Digital Book.
"Time to make an entrance," he whispered. "Authority: Narrative Manifestation."
With a shimmer of white static, the air behind the sand dune buckled. Instead of his modern hoodie, Ken's clothes shifted. His black jazz pants toughened into leather breeches, and his hoodie transformed into a lightweight, dark tunic reinforced with silver-lined pauldrons. At his hip, a short, sleek blade—more for show than slaughter—materialized in a black scabbard.
But he didn't just walk down. From the "margins" of the world, he pulled a white horse-drawn carriage, its wood polished to a mirror finish and its wheels silent against the sand. It looked like something out of a high-class fantasy manga, completely out of place on the desolate beach of Paradis.
Clop. Clop. Clop.
The Scouts spun around, blades halfway out of their scabbards. Levi's eyes narrowed to slits, and Mikasa stepped instinctively in front of Eren.
"Who goes there?" Levi's voice was like a whip.
Ken stepped out from behind the carriage, his frizzy white hair blowing wildly. He raised his hands, showing he wasn't reaching for his sword. "Just a wanderer," he said, his blue eyes bright with a friendly, knowing spark. "The name's Ken. I heard there was a celebration at the end of the world, and I didn't want to miss it."
The tension didn't vanish, but the sheer absurdity of a well-dressed teenager with a luxury carriage in the middle of nowhere disarmed them. After a long, tense silence, Sasha's stomach let out a thunderous growl.
Ken laughed, reaching into the carriage and pulling out a basket overflowing with food that shouldn't exist in their world—fresh fruits, steaming bread, and roasted meats seasoned with spices from across the multiverse. "I brought snacks. Anyone hungry?"
The Feast at the Edge
An hour later, the "enemies across the sea" were momentarily forgotten. The Scouts sat in a circle on the sand, sharing the impossible feast Ken had provided.
"This... this is amazing!" Sasha cried, her face stuffed with a strange, sweet fruit (a mango Ken had 'borrowed' from a different manga). "Is this what the outside world tastes like?"
"Something like that," Ken replied, sitting cross-legged next to Armin. He watched them with a warmth he hadn't felt in a long time. To the world, they were soldiers; to him, they were just kids who had been through too much.
"You're not from the Walls," Eren said, his gaze fixed on Ken. It wasn't an accusation, just a statement of fact. "And you're not from Marley either. Your eyes... they look like they've seen more than just the ocean."
Ken took a bite of bread, looking out at the waves. "I've seen a lot of stories, Eren. Some good, some... very bad. I'm here because I want to see how yours ends."
He turned to the group, his expression becoming serious but kind. "I'm heading toward the horizon myself. I've got a carriage, plenty of supplies, and a few... 'tricks' up my sleeve. Would you mind if I joined your journey? At least until the next island?"
Armin looked at Eren, then at the horizon. The presence of this strange boy felt like a shield against the darkness they were about to face.
"The next island is far," Armin said softly. "But we'd be glad for the company, Ken."
Ken smiled, the blue in his eyes pulsing. The first stitch in the new timeline had been sewn.
