The world was beginning to shake—and not just underfoot.
It trembled in concept.
Since the day Arata Uchiha awoke in this cursed world with eyes he had no right to possess, he feared he was dreaming. Now he feared he was dreamt.
And the dream was waking up.

Capital Command – Two Days After the Spiralborn Emergence
The map table was surrounded by tired faces. Erwin, Levi, Hange, and even Commander Pixis were gathered. They all looked at him.
Not Eren.
Not Historia.
Arata.
Levi broke the silence. "So you're saying this new Titan… doesn't come from Ymir's bloodline?"
"No," Arata said. "It comes from mine."
He stepped forward and placed a shard of broken glass on the table. Inside it shimmered a still image of a grotesque Titan—spiral horns, extra arms, and no eyes. Only a third rotating socket in the center of its head.
"It's not a Titan in the biological sense," Arata said. "It's a story fragment. A being written into reality from a world that never should've touched this one."

Armin's Theory
Armin connected the dots.
"If Kaen can create Titan variants by rewriting fragments of our world's rules… then this isn't war anymore."
Hange nodded slowly.
"It's plagiarism."

Scene Shift – A Deal with the Devil
Far outside the walls, at the abandoned temple ruins of Ostwall, Kaen waited in front of a broken statue of Ymir Fritz.
"Funny," he mused. "The mother of Titans… without a face."
From the trees, Annie Leonhart emerged—cloak damp with rain, eyes sharp.
"You said you had a gift," she said. "Let's see it."
Kaen extended a hand. A scroll materialized in his palm—chakra-infused, soaked in red ink.
"Your Female Titan," he said, "is half a key. This will give you the other."
Annie opened the scroll. Her pupils dilated. It wasn't instructions—it was conceptual code. A mutation of abilities drawn from the Naruto universe.
"Shikotsumyaku," Kaen whispered. "The Dance of the Bone."

Meanwhile – Within Arata's Mind
He stood in a void, staring at himself—or rather, the version of him that once laughed over manga in a Tokyo train station.
"How did this happen?" he asked the void.
The echo responded with his own voice.
"You believed too hard," it said. "And belief in fiction… is dangerous when the universe listens."

Wall Rose – New Titan Emerges
An unnatural rumbling split the air. Everyone looked up.
A Titan—a Female class—came sprinting across the horizon. But something was off.
Bones extended from her forearms like blades.
Her body moved with inhuman speed—then stopped mid-sprint to twist midair, slamming into another Titan with the force of a thousand chakras.
Annie—awakened.
Arata's eyes widened.
"She accepted it."
Mikasa jumped down beside him. "That's not our Titan power. That's something else."
"No," Arata said darkly. "That's fanfiction."

Kaen's Broadcast
Kaen's voice echoed from nowhere and everywhere.
"I've just rewritten one Titan. There are eight more. When all nine accept their new forms, this world will evolve—or collapse."
He paused.
"And Arata? If you won't become the Spiral King… I'll make them crown me instead."

Final Scene – The Library of Ymir
Arata finds himself drawn by his eyes—his Mangekyō evolving slowly, fragmenting. Inside a hidden chamber deep below the capital, he uncovers the Library of Ymir—a place not of books, but scripts.
Scripts of alternate worlds.
> Naruto.
Bleach.
Fullmetal Alchemist.
Attack on Titan.
All stored here.
A museum of fiction… in a world that never had it.
"Kaen didn't break the world," Arata whispered.
"I did."
