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

Why would the gentle Tanjiro point at her with an expression that says, "She did it"?

Yuko experienced a brief system outage.

Before she could react, a figure leaped out from behind Tanjiro and quickly approached.

A cold glint flashed in Yuko's eyes, and she instinctively drew her sword to parry.

Hey~

A crisp sound.

Two blades, one black and one blue, clashed together.

???

Can anyone tell her why the story changed so much when she was only gone for a short while?

Or perhaps she made a mistake in her little notebook; Giyuu actually went home with them to bury Tanjiro's family before leaving.

She knew it! Too much time would cause problems!

Yuko blocked Giyuu's blade and quickly shouted, "Wait..."

Before she could even open her mouth, Yiyong calmly interrupted, "Where are the others?"

it's wired……

She smelled faintly of wisteria blossoms. Was this woman really a ghost?

Before Yuko could speak, Yiyong's eyes flickered as he noticed the character '灭' (destroy) engraved on the blade.

Demon Slayer Squad?

The configuration of the Nichirin Blades used by Demon Slayer Corps swordsmen is divided into two levels: ordinary members and Pillars. Even ordinary members of the Class A rank are not allowed to carve words on their blades.

The Nichirin Blades of the Pillars are all engraved with the words "Demon Slayer". Although this sword is slightly different, it is undoubtedly a Nichirin Blade.

"Ah, Nezuko!"

As Giyuu and Ikuko were locked in a stalemate, Tanjiro suddenly cried out from behind them.

Yi Yong was slightly distracted and looked back, only to see a head suddenly slam into his waist, knocking him away.

He slid a track in the snow and steadied himself, looking towards Yuko.

Nezuko was standing in front of her, looking at her warily.

Yi Yong: "..."

Yuko sheathed her Nichirin Blade, put her hands under Nezuko's armpits, picked her up and placed her behind her, then turned around and explained, "I've settled the Kamado family down the mountain."

Looking at Nezuko, who was standing motionless behind her, Giyuu's eyes flickered slightly. Before he could speak, Tanjiro, who was already extremely anxious, hurriedly asked.

Where is everyone?

Yuko: "In the town at the foot of the mountain, I arranged for them to stay at my place."

Tanjiro was slightly taken aback. "Your residence?"

That makes sense, and he felt that the person in front of him did indeed have a very familiar scent.

Tanjiro exclaimed in surprise, "That mansion?!"

It smells exactly like the flowers near that mansion!

Yu Zi nodded slightly.

Tanjiro's eyes lit up slightly: "You're that sheltered young lady who never leaves her house?!"

“…” Yu Zi’s nodding motion froze, and she twitched her lips. “I suppose so.”

Knowing that his family was safe, Tanjiro finally breathed a sigh of relief and had the leisure to take a closer look at Ikuko.

He was too anxious to pay attention to the other person's appearance, but now that he's calmed down, Tanjiro feels ashamed.

What a beautiful older sister...

Giyu looked left and right, then silently put away his Nichirin Blade.

He looked up at Yuko, his gaze calm: "Demon Slayer Corps?"

Yu Zi shook her head slightly: "No."

Giyu frowned slightly. He knew that if a Demon Slayer Corps swordsman left the team, they would definitely retrieve the Nichirin Blade.

There is no possibility of any outflow.

Moreover, although he couldn't tell what breathing technique the woman in front of him was practicing, judging from her steady and orderly breathing, she had definitely mastered some kind of breathing skill.

Yiyong asked, "Where is the evil spirit that attacked their house?"

Was he stabbed by this woman?

Yuko looked up at him and said, "It's Muzan Kibutsuji."

Yi Yong's pupils contracted slightly, and a slight ripple appeared in his calm expression.

Noticing the tense atmosphere, Tanjiro asked in confusion, "Who is that?"

Yuko explained, "The progenitor of demons, a being akin to a demon king."

Tanjiro couldn't yet grasp the weight of that name, but he knew that Nezuko's transformation was all because of her.

Tanjiro wrote the name down.

Yuko looked up at the sky: "Let's go down the mountain before the sun comes up. I think Sister Aoi must be worried."

Hearing his mother's name, Tanjiro felt even more at ease.

The three people and one ghost... no, the two people and two ghosts started walking down the mountain.

Seeing Nezuko clinging to Ikuko's clothes, Tanjiro waved his hand and said, "Nezuko, come here."

Nezuko glanced at him, then at Yuko, and decisively lowered her head.

Click~

Tanjiro instantly turned to stone.

Yi Yong didn't say anything, nor did he walk with the three of them; instead, he silently trailed behind.

His calm gaze followed Yuko's retreating figure.

Yuko tilted her head slightly and gently pushed Nezuko toward Tanjiro. She slowed her pace by a couple of beats and gradually moved to be parallel to Giyu.

Yi Yong glanced at her, remaining expressionless.

It would be unwise to compete with him in silence.

Yuko spoke first: "Mr. Mizuki, I wonder if you could introduce me to Ubuyashiki?"

She originally planned to travel with Tanjiro, but the plan changed, and Tanjiro needed to study with Giyu for one or two years.

She should probably find some time to re-establish contact with the Ubuyashiki family.

The current head of the Ubuyashiki family seems to have a lot of personal charisma, and I believe things will turn out well.

Upon hearing this, Yi Yong instinctively turned his head to look.

He's not a member of the Demon Slayer Corps, yet he's so familiar with them, wields a Nichirin Blade, and even knows the name of Muzan Kibutsuji.

Who exactly is this woman?

Yuko seemed to sense his confusion and took the initiative to say, "I wonder if Mr. Mizuki has ever heard of Snow Breathing?"

Giyu Tomioka's expression shifted slightly: "Just call me Giyu."

"I've heard of it," he added at the end.

He had certainly heard of the Breath of Snow.

As a breathing technique as ancient as the Five Great Breathing Techniques, the Snow Breathing technique has not been fully inherited.

This is hardly a question; anyone who has tried this breathing method will understand.

This breathing technique... is completely a mess.

Do not……

Saying it's a mess is actually praising it; it's just a breathing method haphazardly developed by a lunatic.

The previous move was a fairly normal feng shui combination, the next move incorporated fire breathing, and the move after that was lightning breathing.

The conditions for cultivation are already harsh, and the sword shape is so messy. Anyone who tries to master this breathing method will not be able to get out of bed the next day.

The biggest taboo in breathing techniques is switching between them during combat, and this Snow Breathing technique completely absorbs the dregs of breathing techniques.

Whether the ghost is dead or not is unknown, but if you feel even slightly unwell, the next move will paralyze you. The continuity between the moves is so good it makes you question your existence.

It would be a miracle if such a breathing technique had been passed down intact.

If it weren't for the occasional person managing to master a sword-like move, they would have doubted the authenticity of this breathing technique.

Yuko said frankly, "I am a swordsman who has mastered the Snow Breathing technique, and I want to do my part to kill Muzan."

What kind of breathing? What is snow?

Yiyong turned his head, and under Yuko's gaze, his expression gradually became subtle.

Ikuko's heart skipped a beat.

What did she say wrong to make someone with a stoic expression show such a reaction?
