Shihouin Naraku walked through the streets of Konoha, nodding to the countless ninjas greeting him with enthusiasm. Their respect was genuine—but his mind was elsewhere.
He barely registered their words.
His focus was entirely on the system—the mysterious voice that had spoken inside his mind the moment he accepted his promotions.
By the time he arrived home, his composure had almost cracked.
Sliding the door closed behind him, Naraku moved into a quiet room, sat cross-legged on the floor, and whispered, "System?"
[Ding! The Promotion System is at your service!]
Naraku let out a sigh of relief. So it hadn't been a hallucination after all.
He closed his eyes and focused inward.
Soon, the structure of the system unfolded in his mind like a grand interface—simple but overwhelming.
As its name implied, the Promotion System rewarded him every time his official status changed within Konoha's hierarchy. Every promotion granted the highest number of lottery chances. Transfers offered modest rewards. Even demotions came with some compensation—but the system made it clear: progress meant power.
Depending on the significance of the promotion, he could earn anywhere from three to five lottery draws.
And those draws?
They granted treasures, skills, bloodlines—even powers from other worlds.
Naraku grinned. "Let's see what you've got."
A massive wheel appeared within his consciousness. Spinning across it were countless items—some familiar, others straight out of fantasy.
He muttered, "Is that... Byakugan? Sharingan? Genjutsu scrolls? Tailed Beast Chakra? Ten Tails!?"
His jaw nearly dropped.
"And... Devil Fruits? Zanpakutō? Dragon Slayer Magic? Kaio-ken? Senzu beans? Somersault cloud?"
The options blurred together—there were too many to count. Power from every corner of fiction and chakra theory, fused into a single cosmic roulette.
"I want all of it," he whispered, half-joking—and half deadly serious.
The giddiness washed over him.
As a highly skilled Jōnin and Tsunade's disciple, Naraku had long been among Konoha's top-tier medical ninja. But he'd always known he had limits—no bloodline, no clan kekkei genkai to fall back on. His raw strength couldn't match the likes of elite shinobi such as Hatake Kakashi or Might Guy.
But this system—this was the cheat code he'd been waiting for.
A grin spread across his face. "System, how many draws do I have?"
[Host currently has 12 draws available.][System Tip: Drawing ten times in a row increases your chance of obtaining rare magical items.]
Seven draws from his new positions. Five more from the system's "newbie gift package."
"Twelve pulls, huh? Alright then. Ten-draw first!"
[Ding! Begin 10x Draw?]
"Do it."
The roulette wheel in his mind began spinning rapidly. Naraku leaned forward unconsciously, as if watching a real object. His eyes followed the golden pointer as it skipped across countless prizes.
And then—
[Ding! Congratulations, Host has received the following items:]
Excellent Shuriken ×5
High-Grade Military Pills ×5
1,000 Ryo (paper currency)
Fire Style: Head-Hard Technique
Fire Style: Extinguish the Fire
100 Ryo (coins)
Lightning Style: Thunder
All Seven Chakra Attributes (Fire, Water, Wind, Lightning, Earth, Yin, Yang)
Mera-Mera no Mi (Flame-Flame Fruit)
Water Style: Explosive Water Wave
[Ding! Host has mastered 4 new ninjutsu techniques.][Ding! Host has unlocked all 7 Chakra natures.]
Naraku slowly opened his eyes.
In front of him on the floor, a pile of items had materialized out of thin air—coins, weapons, pills wrapped in cloth, and one particularly bizarre object.
A crimson fruit, swirling with fire-like patterns.
"The... Mera-Mera Fruit," Naraku breathed, reaching out with reverence.
[Mera-Mera no Mi: Grants the user fire-based elemental transformation and control. Body becomes intangible flame. Side effects of traditional seawater do not apply in this world.]
He clenched it in his fist, grinning. Perfect.
Most shinobi, despite their chakra power, had fragile bodies. A well-placed kunai, a hidden trap—it was enough to end even an elite ninja's life. He had seen too many skilled warriors die in the war to doubt that.
But this fruit?
Elementalization.Invulnerability to physical attacks.Pure fire incarnate.
It was exactly what he needed.
Naraku raised the fruit and took a bite—only to immediately gag.
"Ugh—! What the hell is this taste?!"
He tried to swallow, but it was like chewing a mix of ash, sludge, and rotting medicine. His body shook, but he forced the rest down.
Moments later, he lifted his hand.
Whoosh.
A flame ignited in his palm, flickering and dancing without a single hand sign.
He stared in awe.
"Perfect... no hand seals needed. Fire at will."
Naraku stood.
"The first draw gave me the Mera-Mera Fruit. I can't imagine what comes next."
From that moment, his goal crystallized.
Promotion. Constant promotion.
He would ascend through the ranks of Konoha until no one could stop him.
Later — Deep in the Forest, Training Grounds
BOOM!
Explosions rocked the trees. Gravel scattered. Heat waves spread across the clearing.
When the flames faded, Naraku stood at the center of the devastation—smoke rising around him, his eyes glowing faintly from chakra overflow.
He clenched his fists.
"This power… Even if I'm not Kage-level yet, I'm getting close."
The Mera-Mera Fruit had amplified his Fire Style techniques far beyond their original potential. And now, with all seven chakra natures unlocked, his versatility rivaled even elite jonin commanders.
He grinned again.
There were few in Konoha who could ever claim to rival his Fire Style—before this, perhaps only Uchiha-level users. Now?
Now, there was no one better.
No hand seals. No delay. Just flame.
Like Hashirama molding Wood Style through will alone, Naraku now willed fire into existence.
And this was only the beginning.
Strength is everything.
And for the first time since awakening in this world, Naraku felt unstoppable.
