Demon Slayer: The Journey That Began When I Became Yoriichi's Sister

A soft, gentle voice, tinged with a touch of maturity, drifted lightly into Yuko's ears.

Yuko glanced up unintentionally, and the back of her head bumped against Shinobu Kocho's nascent human heart, causing her to pause slightly in surprise.

It's surprisingly informative.

"Hmm." A faint herbal fragrance wafted from Shinobu Kocho, reaching her nostrils and then her brain, and Ikuko couldn't help but close her eyes in comfort.

But before she could enjoy it for long, Yuko opened her eyes expressionlessly.

Her crimson double pupils stared intently at the masked man in front of her, who was hunched over and whose fingers were less than three centimeters away from her Nichirin Blade.

Steel Tomb shuddered, a chill running down his spine and straight to the top of his head, his neck stiffly turning around.

Yuko covered her face and waved her hand casually.

Steel Mound immediately sat upright and kowtowed several times, then grabbed Yuko's Nichirin Blade and slipped outside.

Immediately, you could hear the two swordsmiths exclaiming in surprise.

Shinobu Kocho, Ikuko: "..."

He's a guy who can be flexible and adaptable.

"That's enough, it's very comfortable." Distracted by Hideaki, Yuuko lost her desire to rest. She turned back and gave Shinobu a slight smile before getting up and leaving the room.

"Haha, how was it?!"

In the corridor, Tanjiro and Inosuke were admiring the two swords that Tanjiro had hammered into art.

I have to say, this guy's skills are really good; he managed to knock them so evenly.

In another corner, two swordsmiths were lying face down with their buttocks sticking out.

"See? I told you it was a good knife."

"Hmm! This is truly a rare and excellent knife; it's hard to imagine the skill of the craftsman."

"By the way! Who is the master forger? Could you..." Before Iron Cave Sen could finish speaking, Iron Mound slapped him on the head.

"Idiot! Didn't you see the word 'annihilate'? That's the knife from before the birth of the class system. Are you trying to dig up a grave?"

Ikuko: "..."

Ignoring the two, Yuko looked down at Tanjiro and said, "Tanjiro."

Tanjiro looked up and asked, "Miss Ikuko?"

Yu Zi chuckled lightly: "We talked about this before, right? After you master Chang Zhong's skills, I'll give you this knife."

Shinobu Kocho, who followed behind her, was slightly taken aback.

Yuko is indeed raising this child as her successor.

Before Tanjiro could speak, Steel Mine jumped up.

"How could..."

Yuko glanced at him sideways, and Steel Mound shivered, quickly shutting his mouth and lying back down.

Tanjiro broke out in a cold sweat and said seriously, "I find the swords forged by Mr. Hidezuka very easy to use, and I would like to continue using them if possible."

At this point, Tanjiro smiled and said, "It's not good to just throw away your own sword."

Moreover, he felt that the knife was very important to Miss Yuko.

Yuko lowered her eyelids slightly, about to speak.

Hidetoshika delivered a Leo Flying Kick that sent Tanjiro flying: "You damn brat! Don't think I'll be impressed by your touching words!"

Inosuke laughed heartily: "I'm here too!"

Yuko's head started to ache again; none of these people were normal.

Speaking of which... where is Zenitsu?

Finally, Ikuko found him in the room where Nezuko was kept; he was squatting next to the box, bothering Nezuko.

Sure enough, none of them were normal.

……

Time rewinds slightly.

Infinite city.

The ghosts who came here again felt something was wrong, because the woman who suddenly appeared in front of them had a gloomy face and was releasing a violent aura without any disguise.

The moment they met, the ghosts knew the woman's identity.

All the demons knelt down in unison: "Lord Muzan!"

Muzan Kibutsuji was in a bad mood.

Ever since she met the demon hunter wearing the flower card, she had had a very bad feeling.

Sure enough, the premonition came true.

Muzan's face darkened: "Rui was killed by that demon slayer wearing the flower card."

Because he was somewhat concerned about that kid, Muzan had been keeping a close eye on the situation of the Lower Rank Demons.

The successor to that monster.

He was so weak at the beginning, but now he has grown to the point that he can fight and defeat his Twelve Demon Moons.

That kid is growing at an unimaginable speed.

Only then did the demons notice that one of the Lower Moon demons was missing.

Lower Moon Four Zero was trembling all over: "I'm so sorry, I couldn't find the demon slayer you mentioned."

"Ah, of course I know."

If Muzan hadn't known that they were indeed doing as he instructed, he would have removed the Lower Moon demons from their positions long ago.

Despite being his direct subordinate unit, they were incredibly weak.

Without giving the ghosts a chance to resist, several thick whips pierced into their bodies.

"I will give you my blood, and you will become stronger."

"Go and find that demon hunter for me."

Muzan looked down at the demons struggling in pain with a gloomy expression.

This time, there will be absolutely no surprises.

……

After three months of recuperation, everyone has fully recovered.

Tanjiro's promotion was not a grand affair; even among the Pillars, only Shinobu Kocho, who was stationed at the Butterfly Mansion, was present.

Having met Kagaya Ubuyashiki and accompanied Shinobu Kocho back, Tanjiro was successfully promoted to the position of Sun Hashira of the Demon Slayer Corps.

Zenitsu stomped his feet in exasperation: "That damn Tanjiro! How dare he run away!"

"I was supposed to become the Sound Pillar! You were lucky to run into the Lower Moon Demon first!"

He had already envisioned himself becoming the Sound Pillar and being worshipped by countless girls.

Tanjiro gave an awkward smile, looking a little embarrassed.

Inosuke waved his hand dismissively and said coldly, "No, no, you were probably terrified back then."

Zenitsu instantly bristled: "Damn it! Who's afraid of me!"

Shinobu Kocho watched this scene with a smile: "Tanjiro, you're quite talented."

"Mmm." Yu Zi pursed her lips slightly.

Rather, it's more accurate to say that all three of them are quite talented.

As the main characters, it's only natural that they possess the qualifications to become Pillars.

It would be even better if it were a little more mature.

A black feather drifted across the sky; it was Yuko's snow jay.

"Tanjiro! Inosuke, Zenitsu! Next mission: The Mugen Train!"

The playful fighting stopped instantly.

Yu Zi's expression shifted slightly. "They've finally arrived."

Because she was worried that the missions assigned to Tanjiro would be different after he became a Pillar, Ikuko informed Ubuyashiki in advance that she needed to notify her of any missions that needed to be assigned to Tanjiro.

The Mugen Train is where Upper Moon Three appears.

Inosuke shouted, "Waaaa!! I want to become a Pillar too!"

"Idiot! Do you think the Twelve Demon Moons are as common as cabbage?" Zenitsu couldn't help but retort. "Many people never encounter them in their entire lives, and we've only just experienced them. They're not that easy to come by."

"..." Yuko took out a strip of cloth to cover her face after a long time and turned to look at the Nichirin Blade.

With a suppressed laugh, Butterfly handed over the Nichirin Blade: "Be careful in everything you do."
