She arrived at dawn.
Naruto saw her from his window—a small figure walking up the street with the casual confidence of someone who owned the ground beneath her feet. Gray hair pulled back in a severe knot. Robes that had seen better decades. A staff that tapped against the stones with every step, marking her progress like a clock counting down.
He didn't recognize her.
That was strange. Naruto knew everyone in the village who mattered—the Hokage, the jonin, the old ladies who ran the shops, the guys at the ramen stand. This woman was new. And new in Konoha usually meant trouble.
The knock came three minutes later. Not urgent. Just patient. Like she had all day and knew he had nothing better to do.
Naruto opened the door.
The woman was shorter than him. Old enough that her face had settled into permanent lines, deep grooves around her mouth and eyes that spoke of decades of smiling and frowning in equal measure. Her eyes were pale gray, almost colorless, and they looked at him the way a farmer looks at a field—calculating. Wondering what would grow.
"You're the boy," she said. Her voice was rough. Smoker's voice. Storyteller's voice. "The one who ate something he shouldn't have."
"Who are you?"
"Name's Chiyo. Came from Suna. Heard you needed a teacher who knows about things that aren't chakra." She pushed past him into the apartment, looking around at the mess with an expression of mild disgust. "Nice place. Really says 'I live alone and hate myself.'"
Naruto bristled. "Hey—"
"Shut up. I didn't come here to make friends." She sat on his only chair like she owned it. "I came here because your Hokage asked nicely and because I'm curious. I've spent sixty years studying things that shouldn't exist. Devil Fruits? I've seen three. Touched one. Watched a man turn into lightning and never come back." She pointed her staff at him. "You're my fourth. And apparently you're special. The Yami Yami hasn't appeared in four hundred years. Everyone thought it was gone forever."
Naruto leaned against the wall. "Everyone was wrong."
"Obviously." Chiyo studied him with those pale eyes. "Show me."
"Show you what?"
"The power. The darkness. I need to see what we're dealing with."
Naruto hesitated. The darkness inside him stirred, curious, cautious. She's not lying, it murmured. She's really curious. Also really old. I like old people. They taste like memories.
"Shut up," Naruto muttered.
Chiyo's eyebrow rose. "Talking to it already? That's fast. Most users take years before the fruit develops a voice."
"It talks a lot. It's annoying."
"Good. Means it likes you. The fruits are picky. They don't talk to vessels they don't respect." She leaned forward. "Now show me. And try not to destroy anything. Your apartment is already depressing enough without holes in the wall."
Naruto took a breath. Closed his eyes. Reached for the darkness the way he reached for his chakra—except it wasn't the same. Chakra was part of him. The darkness was... company. A guest. A roommate who never left.
He opened his hand.
Darkness pooled in his palm. Not shadow, not smoke—something denser. Heavier. It sat there like liquid night, absorbing the light from the room, making the corners feel suddenly closer.
Chiyo leaned in. Her face was rapt, hungry for knowledge in a way that reminded Naruto of Orochimaru. But her eyes weren't cruel. Just old. Just desperate to understand before she died.
"Amazing," she whispered. "The density. The weight. I can feel it pulling at me." She reached out a finger.
"Don't," Naruto said. "It might—"
Too late.
Her finger touched the darkness.
For one frozen moment, nothing happened. Then Chiyo's eyes went wide. Her mouth opened. Her hand dissolved—not in blood or gore, but in slow, silent disappearance. Finger first. Then knuckle. Then palm.
Naruto yanked the darkness back. It fought him, hungry, wanting more. He forced it down with everything he had, shoved it deep into the box inside himself, slammed the lid shut.
Chiyo stared at her hand.
It was whole.
She flexed fingers that should have been gone, touched her palm with the other hand, laughed—a dry, cackling sound that filled the room like smoke.
"Genjutsu," she said. "Your darkness put me in a genjutsu. Made me think I was disappearing. But I wasn't. I was standing here the whole time, watching myself dissolve." She looked at him with new respect. "That's not just power. That's subtle. The Yami Yami doesn't just destroy—it deceives. It makes you doubt what's real."
Naruto's heart hammered in his chest. "I didn't mean to—"
"I know. That's what makes it dangerous. You're not controlling it yet. You're just... coexisting." She stood, grabbed her staff. "First lesson starts now. We're going to the forest. You're going to try to hurt me. And I'm going to teach you what happens when your power meets someone who isn't afraid to die."
---
The forest was the same one where Naruto had trained for a thousand years, it felt like. The same trees. The same clearing where he'd learned the Rasengan, where he'd fought Sasuke, where he'd screamed his frustrations into the uncaring sky.
Chiyo stood in the center, staff planted, waiting.
"Hit me," she said.
"What?"
"Hit me. Use the darkness. Use chakra. Use whatever you want. Try to hurt me."
Naruto shook his head. "I'm not going to—"
She moved.
For an old woman, she was fast—faster than Kakashi, faster than anyone Naruto had fought. Her staff caught him in the ribs, folded him in half, sent him flying into a tree. He hit hard, felt bark dig into his back, slid down gasping.
"Hit. Me." Chiyo stood over him. "Or I'll keep beating you until you do."
Naruto's temper flared. The darkness rose to meet it, eager, hungry for violence. He let it come.
Darkness exploded from his chest—not in a column this time, but in tendrils, whips of absolute black that lashed toward Chiyo from every angle. They wrapped around her staff, her arms, her legs. Started to pull.
Chiyo smiled.
She moved through them.
Not dodging—passing. Like the darkness was water and she was smoke. The tendrils closed on empty air while she reappeared behind Naruto, staff tapping his shoulder.
"Interesting," she said. "Your darkness can touch physical things. It can absorb them, destroy them, pull them. But it can't touch what isn't there. I'm not real right now. I'm a puppet."
Naruto spun. She was gone. Another Chiyo stood by the tree line. Another by the river. Another above him in the branches.
"Puppet technique," multiple voices said. "Sunas specialty. I control a hundred of these from a safe distance. The real me is two miles away, drinking tea." The puppets advanced. "Your darkness can't hurt what it can't find. Remember that."
The puppets attacked.
Naruto fought back. Darkness met wood and wire, dissolving puppet after puppet, but more kept coming. They swarmed him, hit him, cut him. He was losing. He was always losing.
Stop fighting the puppets, the darkness hissed. Fight the strings.
Naruto looked.
Threads of chakra stretched from each puppet, thin as spider silk, leading back into the forest. He couldn't see them with his eyes—but the darkness could. It showed him. It tasted them.
He reached out. Grabbed one.
The puppet attached to it went limp. He grabbed another. Another. Another. Each time he touched a thread, the chakra flowed into him, feeding the darkness, making it stronger.
Yes, it purred. More. Drink.
Two miles away, Chiyo choked on her tea.
Her puppets fell like marionettes with cut strings. Every thread she sent, every bit of chakra she extended—Naruto was absorbing it. Drinking it. Turning her own technique against her.
She did the only thing she could.
She let go.
All the threads vanished at once. Naruto stood in the clearing, surrounded by broken puppets, gasping, shaking, the darkness roaring inside him for more.
Why did she stop? it demanded. We were winning!
Naruto didn't answer. He was too busy feeling what he'd done. The chakra he'd absorbed—it was still inside him. Warm. Alive. Her. He could taste her fear, her surprise, her grudging respect.
He'd hurt her without touching her.
He'd fed on her.
And part of him wanted to do it again.
---
Chiyo found him an hour later, sitting by the river, washing blood from his hands. She walked slowly, favoring one leg—the chakra drain had taken more out of her than she'd expected.
"That was impressive," she said, sitting beside him. "And terrifying. You didn't just beat my technique—you ate it. I've never seen anything like that."
Naruto didn't look up. "I almost killed you."
"No. You almost fed on me. There's a difference." She pulled out a pipe, lit it, blew smoke at the water. "The Yami Yami absorbs. That's its nature. It takes energy, matter, even powers, and makes them part of you. But here's the thing—it can only take what you're willing to consume. You control the hunger. Not the other way around."
"It doesn't feel like I control it."
"Good. That's the first step to actually controlling it." She tapped his shoulder with her pipe. "You're afraid of what you might become. That fear will save you. The users who aren't afraid—they're the ones who become monsters."
Naruto looked at his hands. Clean now. Normal. "How do I stop wanting more?"
"You don't. You learn to want other things more." Chiyo stood, brushed off her robes. "You want to be Hokage, right? You want to protect your friends? Hold onto that. When the hunger gets loud, you think about them. You think about what you'd lose if you gave in."
She started walking back toward the village.
"Same time tomorrow. And bring food. I'm too old to train on an empty stomach."
Naruto watched her go. The darkness stirred inside him, quieter now, almost thoughtful.
She's smart, it admitted. For someone who tastes like old tea and regret.
"Shut up."
Make me.
For the first time since the bridge, Naruto smiled.
