Hidden mission?
Speedrun Demon Slayer?
Naturally, the faster, the better!
Originally, after Naruto entered the Demon Slayer world, he wasn't in a hurry to eliminate all the demons. Instead, he joined the Demon Slayer Corps according to the mission and prepared to use the power of the Demon Slayer Corps and the Ubuyashiki family to find the traces of the Twelve Kizuki and Kibutsuji Muzan, eliminating them one by one.
But now.
A hidden mission has appeared, and it requires a speedrun.
Naturally, the faster, the better!
"Could he, like the creator of the breathing techniques, possess power that no one in this era can match?"
A huge wave surged in Yashiki Ubuyashiki's heart, but his expression remained gentle and calm. He smiled and said, "Hashira's idea,
My Ubuyashiki family will naturally cooperate fully. I will now mobilize all the crows and Demon Slayer Corps members to search for the demons' whereabouts—"
Before he finished speaking, Naruto's feet left the ground, and he flew into the air.
"No need, I'm in a hurry."
That voice came from mid-air.
Plans can't keep up with changes; he needs to find them himself!
"F-Flew up?"
"Is this some kind of Blood Demon Art?!"
"Breathing techniques definitely can't do this!"
Kanae Kochou, Giyu Tomioka, and others had expressions of disbelief on their faces.
Some of them were exceptionally talented, some had extraordinary physiques, or they used breathing techniques to gain physical endurance and strength far beyond human limits. They could either jump very high or run extremely fast, but no matter what, they couldn't do something as contrary to common sense as flying.
Even the legendary founder of breathing techniques, the strongest swordsman, Yoriichi Tsugikuni, couldn't!
"W-What kind of person is Naruto?"
Kanae Kochou's beautiful eyes shimmered with surprise and doubt.
"Ah! That guy flew up!!"
"It must be a Blood Demon Art, I knew he must be—Naruto, Naruto—"
Shinazugawa Sanemi, the Wind Hashira, who had crawled back from outside the courtyard, saw this scene and pointed to the sky, shouting loudly. But before he could say the word "demon," the Stone Hashira covered his mouth while weeping.
Naruto flew higher and higher, looking down at the shrinking Demon Slayer Corps headquarters like a deity. His gaze swept over the sea of wisteria flowers, looking out at the distant green mountains.
"Since Douma, Upper Moon Two, is dead, Kibutsuji Muzan must have been alarmed and will gather the Twelve Kizuki in the Infinity Castle."
"I just need to find one of the Twelve Kizuki, and I can take the opportunity to infiltrate the Infinity Castle, which is hidden in an alternate dimension."
Naruto scanned the surroundings, various thoughts flashing through his mind.
The Twelve Kizuki—he recalled them.
Among them, the most impressive were a few Upper Moons, such as Kokushibo, Akaza, Gyutaro, and so on.
The Lower Moons had changed quite a bit. Rui, Lower Moon Five, who was killed by the original protagonist group on Mount Natagumo, was famous and equally impressive, but according to the current timeline, Rui might not have become one of the Twelve Kizuki yet.
"Mount Natagumo is hard to find, and Rui might not be one of the Twelve Kizuki right now."
"The safest bet is to find the six Upper Moons."
"Kokushibo should stay in the Infinity Castle year-round and rarely move out, Akaza's whereabouts are unknown, and so are Hantengu and Gyokko."
"The easiest to find is Gyutaro."
"If I remember correctly, the Gyutaro siblings have always been hiding in the Yoshiwara Pleasure District."
Mount Natagumo is hard to find, but the Yoshiwara Pleasure District isn't, right?
"Ubuyashiki Family Head, which direction is the Yoshiwara Pleasure District?"
A voice echoed in Yashiki Ubuyashiki's ears.
It wasn't loud, but it was very clear.
"It's Hashira!"
"He hasn't left yet?"
While Yashiki Ubuyashiki was startled, he instinctively looked up, wanting to find Naruto's figure.
Unfortunately, he couldn't see him.
"Hashira-sama, the Yoshiwara Pleasure District is in the northeast direction."
Although Yashiki Ubuyashiki didn't know why Naruto was looking for the Yoshiwara Pleasure District, he answered truthfully.
As for whether Naruto could hear his voice, Yashiki Ubuyashiki knew that was not something he needed to worry about.
"Northeast direction, huh?"
After locking onto the target, Naruto immediately activated Shadow Instant Kill Array, while also using his Mind's Eye of the Kagura, constantly teleporting and searching his way back.
A few breaths later.
"Whoosh."
Naruto appeared on a rooftop, right next to the famous Yoshiwara Pleasure District.
The sound of shamisen strings mixed with hoarse singing seeped out from between the vermilion window sills, clinging to every inch of the air like sticky honey.
The entire street was bathed in the crimson light of lanterns, and the gilded and painted eaves intertwined with light and shadow like monstrous beasts baring their fangs and claws.
The geishas' snow-white necks were faintly visible at the collars of their twelve-layered kimonos, and the hairpins on their elaborate coiffures gently swayed with their deliberately slowed steps. Each step produced the crisp sound of bells and the sweet fragrance of powder.
Prosperous, extravagant, a world of pleasure and debauchery.
However, everything before him had nothing to do with Naruto.
Naruto was out of place in the Yoshiwara Pleasure District, as if he were separated from the world.
He slightly closed his eyes, continuing to use Mind's Eye of the Kagura to deeply search for Gyutaro's whereabouts.
"Gyutaro usually hides behind his sister Daki, and since they are demons, the energy they emit is different from normal people, making them very easy to find."
"It's the Oiran of the Tokito House, the Oiran of the Tokito House is here!"
Someone shouted, and the entire brightly lit Yoshiwara Pleasure District was ignited like a spark falling into a pan of oil.
Amidst the cheers and crowds, a luxurious and magnificent palanquin drove towards a splendid building with a giant peony lantern on its roof.
It was the most popular establishment in the Yoshiwara Pleasure District—the Tokito House.
And the Oiran of the Tokito House, whose popularity far surpassed that of other establishments' top courtesans, was undoubtedly the most popular Oiran in the Yoshiwara Pleasure District.
"Found them."
A sharp glint flashed in Naruto's azure eyes. Ripples spread across the roof tiles he was standing on, and then his feet slowly sank into the shadows.
Next were his instep, ankle, calf—
Finally, his entire body submerged into the shadows like a lake, disappearing from sight.
No one noticed that a shadow was silently moving in the dappled light of the pleasure district.
After Daki, disguised as an Oiran, returned to the Tokito House, she roughly dismissed the flower girls serving her and then slammed the sliding door shut.
One moment Daki was fierce and domineering, the next she was acting spoiled, saying, "Brother, this time when Master Muzan calls us for a meeting, let me participate too, please, good brother~"
The room was empty except for her, but Daki spoke continuously as if talking to herself.
"No!"
"At least not this time, maybe next time, when my sister is stronger."
Another voice, completely different from Daki's, sounded.
A thin man with green-black seaweed-like hair emerged from Daki's back, then continuously separated, crawled onto the ground, and transformed into a completely independent entity.
It was Gyutaro, the demon of Upper Moon Six!
As soon as Gyutaro appeared in such a bizarre manner, Daki immediately pounced on him with excitement and joy.
"Brother, please, I beg you~" Daki said, shaking Gyutaro's arm coquettishly.
