The Face Fruit—a Devil Fruit that never appeared in One Piece, yet somehow exists in the Naruto world.
In his previous life, Ren was what you'd call a "fake nerd"—a guy who liked anime but didn't really watch much. He was the kind of guy who'd show up at every Comic-Con in his city. Not for the merch, not even for the cosplay. Just to see cute girls in costume. A man with simple pleasures.
So, how did he die?
No dramatic car crash. No lightning strike. No tragic accident.
He was conned.
At Comic-Con, a cute girl dressed as Boa Hancock convinced him to buy a "Devil Fruit Cake" for 1,000 dollars. He knew it was overpriced.
But something about her smile—and other features—clouded his judgment. Feeling cheated and blood boiling from embarrassment, he swallowed the entire thing out of spite.
He choked to death on that cake.
Tragic? Absolutely.
When Ren woke up again, it wasn't in a hospital. No white walls. No defibrillator shocks. Just a cold night breeze, a crib, and a pair of cold, calculating eyes looking down at him. He'd been reborn in the Naruto world.
And not just anywhere.
As the son of Shimura Danzo.
To his surprise, Ren didn't just inherit chakra and good genetics. He brought with him the powers of the Face Fruit. On top of that, there was a system embedded in his consciousness.
He didn't notice the system at first. Not until he turned three and had a strange dream. In that dream, he saw a screen—like a computer interface—floating in front of him. It didn't speak. It wasn't sentient. Just a screen etched into his mind, cold and clinical, showing stats like in a game:
Ren: Human
Occupation: Ninja
Abilities: Face Fruit, Clone Technique (White), Body Replacement Technique (White), Transformation Technique (White), Wind Release: Vacuum Sphere (White), Wind Release: Wind Cutter (White)
Simple. No frills.
He tried for years to get more information from the system, poked it, meditated, raged, begged. Nothing worked. It wasn't responsive. But it did automatically update with any new jutsu he learned. He never figured out what the term "(White)" meant beside techniques.
The Face Fruit didn't even have a description. Its functions had to be researched by Ren himself.
Turns out, the fruit creates a golden "field" of influence. If someone is weaker than Ren—in strength, status, or willpower—they would subconsciously submit to him. Respect him. Fear him. A literal power to "give face."
If they didn't give face? If they were stronger, had higher status, or just didn't care about names like "Shimura Danzo?"
Then it triggered the second ability of the fruit.
Face Retaliation.
It wasn't clear what this did yet, but every time someone publicly disrespected Ren, bad luck would follow them. One kid got his front teeth punched out by a monkey. Another slipped down the stairs and broke his arm. Coincidence? Ren didn't think so.
Thanks to his bloodline and Danzo's elite-level training, Ren was already Genin-level before he even graduated from the Academy. Most kids were still learning to mold chakra. He was out here casting Wind Release jutsu like it was a hobby.
Today was just another boring day in the Academy.
Uchiha Canon Fodder #1 had tried to pick a fight with him over seat placement. Ren gave him The Look—a minor field activation. Result? The guy mysteriously tripped on his own sandals and faceplanted. Later, he was quietly admitted to the hospital. Their teacher, a low-ranking Chūnin with no clan background, acted like nothing had happened. Because, well… Danzo's son.
Class, recess, class.
Ren leaned on his elbow, his expression blank. Outside the window, a single sakura petal danced through the air and landed on the sill. Then it was whisked away by the wind.
What a boring class...
He slouched further, one eye drooping, mind drifting. A minute later, soft snores escaped his lips. Uchiha Mikoto, sitting next to him, glanced at him and sighed.
This guy again.
This same bad boy had sneakily brushed her hand last week. Now he was drooling in his sleep beside her.
But even asleep, his face was… kinda cute. Mikoto blushed and looked away, then back again. Before she knew it, she was staring.
Ren woke up to the sound of students packing up. Sunset lit the classroom in golden light.
Their teacher dismissed them with a wave.
Ren stretched and yawned. As he sat up, he found a face close to his own.
Big eyes. Round cheeks with baby fat. A bit too close.
He blinked. Then instinctively reached out and pinched her cheeks.
"Agh! What are you doing?!"
Mikoto slapped his hand away, her face red with embarrassment and fury.
"Pinching you. Mikoto, you're seriously slow. My action was so obvious and you still had to ask?"
He grinned, releasing her cheeks, then sneakily grabbed her hand while she was distracted.
"Mikoto, your hand's so soft. Let me touch it more later, yeah?"
"I... I'm not stupid! And no, it's not okay! Shimura-san, you're such a jerk!"
Flustered, Mikoto yanked her hand free and bolted out of the classroom. Chakra flickered under her feet, and she vanished in a burst of speed.
Unknowingly, Ren's teasing had helped her unlock the basics of the Body Flicker Technique. As the granddaughter of the Uchiha clan's current elder, Mikoto was no slouch in talent.
As the classroom emptied, Ren spotted the next generation of Ino-Shika-Cho still chatting.
He strolled over casually.
"Yo, Shikaku, Inoichi, Choza. Wanna walk back together?"
Shikaku hesitated. His family served the Hokage, and Danzo was a controversial figure. But admiration for Ren's earlier actions won out. Despite being a kid, Shikaku respected strength.
"Sure. Let's go."
Inoichi and Choza followed. As they walked, Ren led the conversation. He casually dropped knowledge about ninjutsu, taijutsu, and even historical ninja conflicts. Choza and Inoichi were in awe.
But Shikaku—Shikaku was analyzing.
Ren knew things no academy student should know.
Eventually, they reached the intersection where the Shimura and Yamanaka-Nara-Akimichi clans parted ways.
"Hey, Shimura-san."
Ren turned.
"Hm?"
"Uchiha Mikoto is important in her clan. Your behavior today… might've gone too far. And be careful around Uchiha Fugaku. My dad says the elders already picked him as the next clan head."
Ren raised an eyebrow. Fugaku, huh? Already climbing the ladder at fourteen. Elite Chūnin. Konoha Police Squad Leader.
He smiled.
"Thanks for the reminder. Don't worry. I've got this handled."
He waved and walked off down his own path.
As he disappeared into the streets, the smile on his lips faded. His eyes turned cold, thoughtful.
Uchiha Fugaku. Fourteen. Elite Chūnin. Police Squad Leader.
So what? Just don't get in my way, or...
