Dawn found him crawling out of the earth.
Ren emerged from the tunnel, blinking against pale light. The forest stretched above him, leaves rustling in the cold wind. Somewhere in the distance, a bird called out—a simple, ordinary sound that felt almost alien after the ancient whispers of the chamber.
Morning. I was in there all night.
He touched the seal on his chest. Warm. Pulsing. A second heartbeat.
I'm alive. But I'm not the same.
His first test came sooner than expected.
A missing-nin—one of the ones from the ambush—lay crumpled against a tree. His throat was slit, his eyes wide open, staring at nothing. The same dead eyes that had watched Daichi fall.
Someone killed him.
Ren knelt beside the body. His hands didn't shake. That surprised him.
A small scroll was tucked in the man's belt. Ren reached for it—and as his fingers brushed the paper, something woke.
Heat exploded up his arm.
Not from the scroll. From the seal on his chest.
The world tilted. Images flooded his mind—not his own memories. The dead man's. A village burning. A child screaming. A blade swinging—
Ren gasped and wrenched his hand back.
The visions stopped.
His heart pounded. His chest ached where the seal burned. Sweat dripped down his face.
What was that?
He looked at his hand. It was shaking now.
Not yet. I don't know enough.
He stood up, stepped away from the body, and kept walking.
The second body was different.
The masked man—the stranger who had pushed Ren toward the cave—lay against a tree, his mask cracked, his chest stained with blood. But his eyes were still open. Still alive.
Ren rushed to his side. "Hey—stay with me."
The stranger's hand shot up and grabbed Ren's wrist. Weak, but desperate.
"Listen..." the stranger rasped. "The seal on your chest... don't let them see it..."
"How do you know about—"
"The council... there's a traitor..."
"Who?"
The stranger coughed. Blood bubbled from his lips.
"Find... the red scroll... in my pouch..."
Ren reached inside. His fingers closed around a small scroll—worn, ancient, sealed with a spiral.
The stranger nodded weakly. "Give it... to no one... not even the Hokage..."
"Why?"
The stranger's eyes locked onto Ren's. For a moment, they were clear.
"Because... you're the last... true heir..."
His hand fell. His eyes went still.
Ren sat there, the scroll clutched in his bloody fingers. Another person dead because of him. He closed the man's eyes.
The last true heir.
What does that mean?
He tucked the scroll into his pouch and kept walking.
He didn't make it far.
A twig snapped behind him. Ren spun around.
A missing-nin stood twenty feet away—not one of the ones from the ambush. This one was fresh. His headband was scratched, his eyes cold.
"You're the one," the man said. "The target."
Ren's hand moved to his kunai.
"I don't know what you're talking about."
The missing-nin smiled. "Doesn't matter. Dead or alive, they pay the same."
He lunged.
Ren dodged—barely. The blade whistled past his ear. He stumbled, caught himself on a tree, and reached for his kunai.
Too fast. I'm too slow.
The missing-nin swung again. Ren threw himself sideways. Pain exploded in his shoulder—a shallow cut, but burning.
I can't win like this.
Something flickered at the edge of his vision. Not words. Not quite. Just… a feeling.
The seal.
Use it.
He didn't know how. He reached for the seal on his chest and pushed.
The world went white.
When his vision cleared, the missing-nin was on the ground.
Not dead—unconscious. His sword lay several feet away. Ren's hand was still pressed against his chest. The seal was burning—hot, angry, alive.
What did I do?
His head pounded. His legs trembled. He felt like he'd run for miles.
Side effects.
Everything has a price.
He didn't wait for the man to wake up. He ran.
Ren reached Konoha by midday, exhausted and shaking.
The gates were busy—merchants, travelers, shinobi coming and going. No one looked at him twice.
They don't know. They don't know what I've become.
He made his way through the streets to his small apartment. Locked the door. Collapsed onto the floor.
The seal on his chest pulsed—faint warmth mixed with lingering pain.
He lay on the cold floor and stared at the ceiling.
The woman in his dream. The blurred face. The blade through her chest.
Was she my mother?
Why me? What am I?
He touched the seal.
Something flickered at the edge of his vision. A feeling. A number he couldn't quite see.
0.3%.
What does that mean?
He closed his eyes.
I'll figure it out. One step at a time.
After a while, he sat up and unrolled the red scroll.
The paper was old—ancient—yellowed with age and cracked at the edges. The symbols on it were unlike anything Ren had ever seen. Spirals within spirals. Seals within seals.
And in the center, a single name:
Mito Uzumaki.
Ren's breath caught.
Mito. The first Jinchuriki. The wife of the First Hokage. An Uzumaki.
He read the text beneath. Old script—hard to understand, but possible.
"To my descendant: If you are reading this, the bloodline has not yet died. There is hope."
"The seals on your body are not curses. They are keys."
"But be warned: The Origin Seal is not a prison. It is a door."
"Do not trust the council. Do not trust the Hokage. Do not trust anyone who seeks to control you."
"Find the temple of the Whirlpool. There, you will learn the truth."
"May the spiral guide you."
Ren read the words again. Then a third time. The name Mito Uzumaki burned in his memory.
She knew. She knew everything.
He rolled up the scroll and tucked it into his shirt, close to his heart.
The temple of the Whirlpool. Where is that?
He didn't know.
But he would find it.
One way or another.
He didn't sleep that night.
He sat in the corner of his room, the mirror from the masked man in his hands—though he didn't know how to use it yet. The seal on his chest pulsed with each heartbeat.
Thump. Pulse. Thump. Pulse.
Like a countdown.
When the sun finally rose, Ren stood up.
His legs didn't shake. His hands were steady.
He looked at himself in the small mirror by the door.
Same face. Same eyes. Same dark hair.
But something was different.
Something behind his eyes.
Cold
He had never seen that look before.
A knock on the door.
"Ren? You in there?"
A voice he didn't recognize. Female. Young.
Ren opened the door.
A kunoichi stood in the hallway—brown hair, sharp eyes, a medical band on her arm.
"You're Ren Uzumaki?" she asked.
The name sounded strange coming from someone else's mouth. No one in Konoha had ever called him that.
"Yes."
"I'm Miyu. Miyu Haruno. The Hokage wants to see you."
Ren's stomach dropped.
The Hokage.
About the mission.
About Daichi. About Sora.
"About my team?" he asked.
Miyu looked away. Then her eyes flicked back to his chest—to the seal hidden beneath his shirt.
For a moment, she froze.
Something flickered across her face. Recognition? Fear? She looked away quickly.
"There was an ambush," she said quietly. "Your sensei… and one of your teammates…"
She didn't finish.
She didn't need to.
Ren stepped out and closed the door behind him.
The red scroll burned against his chest.
She saw it.
The seal.
She knows something.
Here we go.
