Gyutaro was not weak; his Blood Demon Art could unleash thin, blade-like blood slashes, and his two sickles were coated with terrifying poison.
But.
He was merely not weak.
A sharp, cold flash of a blade sliced through the air, and Gyutaro's head, topped with tangled, seaweed-like hair, immediately flew high before falling to the ground with a "thud."
Gyutaro, with his serrated mouth, shrieked, "You can't kill me!"
"That's right, to kill you, I must simultaneously sever the heads of both you and your sister, Daki, correct?"
Naruto's gaze was slightly cold, and his tone was indifferent.
He still remembered the information about the Upper Ranks.
And for a Kage-level ninja who possessed such information, eliminating a mere Twelve Kizuki was simply too easy.
Gyutaro, who had been arrogant just a second ago, his smile instantly froze.
At the same time.
Yoshiwara Pleasure District, underground cavern.
Numerous ornate silk sashes crisscrossed the dark space, each enveloping a young woman like a mummy.
Those were all Daki's food!
Daki, in a bad mood, came to her pantry through a secret passage, her full hips resting on a silk sash, and with a flick of her finger, the sash, like a living thing, immediately brought a tightly bound young woman directly before Daki.
Daki gently ran her five fingers across her face, her chin slightly raised, her eyes glinting with a cold light.
"Old people's meat is too dry and tough to eat, and ugly people are dirty and disgusting to eat."
"Only young and beautiful girls are fit to be my food."
Daki's lips curled into a wicked, cruel smile as her five fingers traced the young girl's face.
"O-Oiran..."
"No, please don't eat me—don't eat me..."
The young girl's voice trembled as she begged, her face filled with terror.
Then, she froze.
Because she saw a blonde young man slowly rising behind Daki.
"What?"
By the time Daki sensed the Shadow Clone's presence, it was already too late.
"Swish, swish, swish—"
The dark underground cavern was instantly illuminated by crescent-shaped Wind Release blades flying everywhere, instantly severing Daki's head,
and those crisscrossing sash clones, into four and five pieces, scattered everywhere.
"You—you can't kill me!"
Daki shrieked hysterically.
"It's fine, I'll kill you every time you revive until the main body severs your brother's head as well," the Shadow Clone responded calmly.
"You—what did you say?"
Daki was instantly horrified.
Their weakness—simultaneous decapitation—no one knew about it, so why did this blonde young man know?
"Brother—Brother!"
"Brother, save me!!"
Daki screamed in fear.
Unfortunately, what awaited her was only repeated decapitations by Wind Release blades.
It wasn't until Naruto's main body in Infinity Castle also severed Gyutaro's head that the Upper Rank Six, Gyutaro and Daki, were completely annihilated.
Infinity Castle.
Naruto killed Gyutaro in an instant.
The moment Gyutaro turned to ash, the Twelve Kizuki reacted with horror, realizing that another Upper Rank had fallen.
And it happened right in Kibutsuji Muzan's main base, in front of all the demons.
"What's going on? Why was Infinity Castle invaded, and I was completely unaware?"
"Gyutaro is dead! Another Upper Rank killed!"
"Could it be that Lord Douma was also killed by him?"
"The blonde young man, is he a Demon Slayer Corps Pillar? He looks so young!"
"If I kill him, I can replace Lord Kokushibo and become Upper Rank One?"
In an instant, numerous thoughts arose among the Twelve Kizuki and the many demons hidden in the shadows.
There was shock, horror, and also joy.
Kibutsuji Muzan was also startled for a moment, but when he saw that Naruto's ears were empty, without Tsugikuni Yoriichi's hanafuda earrings, he couldn't help but breathe a sigh of relief.
He became composed and calm, then spoke in a chilling tone: "Nakime."
"Zheng zheng zheng zheng zheng zheng—"
Understanding, Nakime unleashed her Blood Demon Art with all her might, her long hair floating up, the giant single eye on her face bulging and bloodshot, her fingers frantically plucking the biwa.
"Rumble! Rumble!"
Infinity Castle twisted wildly under Nakime's control, the wooden corridors writhing like giant snakes, space constantly tearing and reassembling.
Wooden corridors, like giant snakes, like high-speed trains, came from all directions, crashing violently towards Naruto, who had just killed Gyutaro.
However, "Rasengan!!"
A flash of light pierced through the void, a huge, bright blue orb of light expanded violently, and a furious Chakra storm instantly pulverized the entire building complex!
"Boom—!!"
Naruto hovered in mid-air, his Dragon Origin Chakra cloak burning like flames, black wings spread behind him, his azure eyes cold as blades.
"None of you guys—not a single one of you will escape."
In front of Kibutsuji Muzan, one closed paper door after another appeared out of thin air.
He had already retreated behind the scenes.
Only the voice of the "Scum Boss" echoed through Infinity Castle.
"Whoever kills him shall become the new Upper Rank One!"
"Roar—!!"
"Kill! Kill! Kill!"
"Humans, die!"
The Infinity Castle, an anomalous space, echoed with the wails and howls of demons.
Whether it was the allure of a great reward or the absolute command of Kibutsuji Muzan.
Naruto's feat of instantly killing Gyutaro and eliminating Douma did not frighten the demons.
Instead, the demons seemed to be pumped up, rushing towards Naruto from all directions within the Infinity Castle's architecture.
"A bunch of things that don't know their place, neither human nor demon."
Naruto formed hand seals, performing Multiple Shadow Clone Jutsu, summoning hundreds of Shadow Clones to attack the many demons hidden within Infinity Castle.
As for his main body... he would personally deal with the Twelve Kizuki.
First, kill the six Lower Ranks!
The current six Lower Ranks were Lower Rank One: Ubume, Lower Rank Two: Hairo, Lower Rank Three: Byouha, Lower Rank Four: Mukago...
But it didn't matter, they all had to die anyway.
"Rip—"
A sharp, crackling sound of thunder, and bright blue Chakra aura and Lightning Release electricity surged around Naruto's body.
This was the Lightning Release Chakra Mode, stimulating cell activation.
Although it hadn't reached the Raikage's Lightning Release Chakra Mode, it was enough to elevate Naruto's speed by another level.
Combined with the second nature transformation, Wind Release Chakra, only a "bang" of a sonic boom was heard.
Naruto, flapping his Shadow Wings, transformed into wind and lightning and charged forward.
The Lower Rank Demons didn't even have time to react; Naruto had already passed through as a blue flash.
"Taijutsu: Instantaneous Consecutive Strikes!"
"Bang! Bang! Bang! Bang! Bang! Bang!"
Six explosive sounds, and the heads of the six Lower Rank demons exploded simultaneously, their headless bodies standing in place, not yet falling, their necks flickering with the electric light of Lightning Release Chakra.
Next up is...
Upper Rank Five: Gyokko!
Having annihilated all six Lower Ranks, Naruto didn't stop at all, directly using Shadow Instant Kill Array to instantly move next to Gyokko. And when Gyokko noticed Naruto disappear from his sight, he immediately, vigilantly, teleported to another pot through the pot beneath him.
