The boy's name was Kaito.
He was nine years old. He liked fish more than meat, couldn't sleep without a lamp on, and had a little sister who still believed he could do no wrong. His mother sold vegetables at the market. His father died two years ago, crushed by a falling tree during a storm.
None of that mattered anymore.
Because three weeks ago, a man had come to their village. Tall. Pale. Smiling like he knew something no one else did. He'd gathered the children in the square, told them stories of distant lands, and handed out fruit to anyone who wanted one.
"Special fruit," he'd said. "From across the sea. Eat it, and you'll never be ordinary again."
Kaito had been hungry. The fruit was free. He'd eaten it without thinking.
Now his village was full of graves he'd dug himself.
"The other children," Naruto asked. They sat in the forest, away from the bodies, away from the survivors who looked at Kaito like he was a monster. "Did they eat the fruit too?"
Kaito nodded, eyes on the ground. "Six of us. I'm the only one left."
"Where are the others?"
"Dead. The fruit... it changed them. Made them do things. Hurt things. The adults tried to stop them and..." He trailed off, shaking.
Sasuke spoke from the shadows. "What happened to the man who gave you the fruit?"
"Gone. He left after we ate. Said he'd be back when we were ready." Kaito looked up. "Ready for what?"
No one answered.

They buried the dead.
Naruto dug graves with his hands because it felt right—because using chakra or darkness for something so human would have been wrong. Sakura tended the wounded, her new healing skills tested by injuries no normal battle should have caused. Sasuke stood guard, Sharingan watching the forest for any sign of the man's return.
He didn't come.
By nightfall, the village was quiet. The survivors huddled in their homes, doors barred, prayers whispered. Naruto sat on a roof with Kaito, watching the stars.
"When I first got my power," Naruto said, "I killed someone too."
Kaito looked at him.
"Not on purpose. I didn't even know what I was doing. But he touched me and he was just... gone. Like he'd never existed." Naruto's voice was flat. "I still dream about it. The way he looked at me before he disappeared. The way his face just... stopped."
"How do you live with it?"
"I don't know. I just do. Every day I wake up and decide to keep going." Naruto looked at the boy. "That's all any of us can do. Keep going. Try to be better than yesterday."
Kaito was quiet for a long time.
Then he asked: "Will you teach me?"
Naruto almost laughed. "I'm not a teacher. I barely know what I'm doing."
"You know more than me." Kaito's voice was small but steady. "You didn't kill me when you could have. That's something."
Naruto looked at the boy's shadow—it was wrong, too dark, moving when it shouldn't. A Devil Fruit user, just like him. Alone and scared and desperate for someone to understand.
"Okay," he said. "But I warn you—I'm a terrible teacher."
Kaito almost smiled.

They found the tracks at dawn.
Sasuke woke them with a hand on Naruto's shoulder, face grim. "Someone was here last night. Watched us. Left these."
He held out a leaf. On it, written in what looked like blood: The seeds have been planted. The harvest comes.
Naruto's blood went cold.
"The man," he said. "He's still here."
"No." Sasuke shook his head. "These tracks are old. A week, maybe more. He left these before we arrived. He knew we'd come."
Naruto stood, scanning the trees. The darkness inside him stretched, searching, tasting—and found nothing. Just the lingering scent of something familiar. Something that made his skin crawl.
I know that smell, the darkness murmured. Old. Powerful. Dangerous.
"Who?"
The ghost from the forest. The one who wants to ride inside you. He was here.
Naruto's hands curled into fists. "He's helping this man? Planting fruits in children?"
Maybe. Or maybe he's just watching. Collecting information. Waiting for you to make a mistake.
Behind them, Kaito stirred. "Naruto? What's wrong?"
Naruto forced a smile. "Nothing. Go back to sleep."
But he didn't sleep. None of them did. They sat in a circle, backs to each other, watching the dark for something that might already be inside.

The next village was worse.
Twenty miles east. Same story. A man had come, given fruit to children, left. But here, no one had survived. The bodies were everywhere—adults and children alike, twisted into shapes that didn't belong to living things. In the center of the village, someone had built a tower of skulls.
On the top skull, another message: Growing strong. Soon ready.
Sakura threw up behind a house. Sasuke's Sharingan spun so fast it left trails of light. Kaito hid his face in Naruto's jacket and shook.
Naruto just stared.
The darkness inside him was screaming—not in warning, but in recognition. It knew this place. Knew the deaths. Knew the power that had been used here.
A Devil Fruit awakening, it whispered. A child whose fruit evolved too fast. Lost control. Killed everyone.
"Can that happen to me?"
Yes. If you stop fighting. If you give in. If you let me take control.
Naruto looked at the skulls. At the children's bones among them.
"Then I'll never stop fighting."
Good. Because if you do... this is what's waiting.

They found the survivor in a root cellar, hidden beneath a pile of turnips.
A girl. Seven, maybe eight. Her eyes were wrong—one normal brown, one pure white with no pupil. When she looked at them, the white eye moved, focusing on each of them in turn like it had a mind of its own.
"You're the ones," she said. Her voice was too old. Too knowing. "The ones he's waiting for."
Naruto knelt in front of her. "Who? Who's waiting?"
"The man who gave us the fruit. He said someone would come. Someone with darkness inside. Someone who could save us." Her white eye fixed on Naruto. "That's you. The darkness inside you is bigger than ours. It's older. It can eat ours and make us normal again."
Naruto went still.
"What did you say?"
The girl reached out. Touched his chest. And Naruto felt something he'd never felt before—another Devil Fruit reaching for his, not to fight, but to merge. To be absorbed. To become part of something larger.
She's offering herself, the darkness whispered. She wants us to eat her fruit. To take her power so she can die human.
"No."
It's what she wants.
"I don't care." Naruto pulled back. "I'm not eating anyone. I'm not taking anything else."
The girl's white eye filled with tears. "But I don't want to be this anymore. I don't want to see what I see. I don't want to know when people are going to die."
Naruto's heart broke.
He pulled her into his arms and held her while she cried.
