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

In the courtyard outside the house, a shirtless boy with a pig's head was running wildly.

"Wait! Inosuke!"

"Mr. Inosuke! Your injuries haven't healed yet, come back quickly!"

Then Tanjiro, wearing a hospital gown, and Aoi Kanzaki chased after them from the corridor, and the three of them started running around the courtyard.

Yuko couldn't help but chuckle, "They're really energetic, I think..."

She turned her head away while laughing, and then her voice stopped abruptly.

Oh my god... that's a scary face.

A shadow fell over Shinobu's face as she silently rose to her feet: "Please sit for a moment."

“…Hmm.” Yu Zi was afraid that her next sentence would be ‘I’m going to take his head.’

"Hahaha~ Charge forward like a pig~ Charge forward like a pig~"

Inosuke was running happily when a figure suddenly appeared in front of him. He quickly braked and finally stopped before hitting Shinobu Kocho.

The dazed pig's head looked down.

Shinobu Kocho smiled and reached out to gently stroke his head: "No, you can't do that."

A suspicious blush appeared on the wild boar's headgear.

“Yes…” He had barely uttered the words when a wild instinct suddenly sent a chill down his spine.

The girl, who had been smiling just moments before, vanished in an instant, her expressionless face turning as she swung her fist, the size of a sandbag, at him.

Even though Inosuke has the instincts of a wild beast, he is still injured and facing a Pillar who is stronger than him, so he has no way to avoid it.

Under the impact, it fell straight down, suspicious foam overflowing from under the mask, and a huge red envelope broke through the mask.

Tanjiro and Aoi Kanzaki, who followed closely behind, couldn't help but swallow hard when they saw the girl who exuded a dark aura.

Shinobu Kocho said with a dark expression, "Take him back and keep a close watch on him. Tie him to the bed."

The two exclaimed in surprise, "Yes!!"

How scary! Miss Shinobu is so scary!

Neither of them dared to say another word. They carried Inosuke away and fled, fearing that if they lingered even a moment longer, Shinobu would beat them up as well.

Watching the three figures leave, Butterfly sighed and returned to Yuko's side: "Really, they were fooling around before their injuries had healed. Their bodies were almost recovered, and now they'll have to lie in bed for a few more days."

Yuko's lips twitched slightly.

No, she feels that this is inextricably linked to you.

……

Yuko could tell that although Shinobu was quite annoyed by the three little ones, she was also enjoying herself.

The atmosphere within the Demon Slayer Corps has never been good, as the pressure from the demons makes it impossible for anyone to be happy.

The arrival of these three people made the Butterfly Mansion unusually lively; in terms of creating excitement, they were practically an army in themselves.

As the three gradually recovered, the rehabilitation training they underwent under the guidance of Kanzaki Aoi was quite interesting.

Seemingly upon learning that Tanjiro had single-handedly defeated Lower Rank 5, Inosuke's spirits visibly soared, and he actively participated in every rehabilitation training session.

Zenitsu Agatsuma is also very proactive, but I always feel that his initiative is not very serious.

Just like.

"Um, Ms. Yuko, could you please help me with my rehabilitation training?" Zenitsu Gasai tossed his hair in a flamboyant manner.

Shinobu's face darkened, and she was about to speak when Ikuko stopped her.

Yu Zi smiled and said, "Okay."

"That's great!" Zenitsu Agatsuma turned around and clenched his fist.

He had already inquired with Tanjiro and learned that Miss Yuko was not a member of the Demon Slayer Corps, but was just a guest visiting the Corps.

The advantage is his.

The two sat down at the table, on which were several cups of tea.

Zenitsu Gasai's eyes sparkled: "Miss Ikuko, please."

"Has it started yet?"

"Hmm, Madam..."

puff……

His face was covered in wet tea.

Zenitsu Gasai paused for a moment, "I wasn't prepared just now."

"Okay, let's start over then."

puff.

"I just……"

Fifteen minutes later, Yuko got up in a cheerful mood.

Zenitsu Agatsuma, on the other hand, sat there, soaked to the bone.

Yu Zi nodded in satisfaction. This guy's attention was completely focused on her hands during the game; he was truly something else.

"Ren, go sunbathe."

Butterfly chuckled and replied, "Mm."

……

After the brief incident, Tanjiro defeated the Great Demon King Kanao first, while the other two continued their efforts.

As for the techniques of Concentrated Breathing, Tanjiro fully mastered them while defeating Lower Moon Five Rui, which is very much in line with the objective impression of a protagonist breaking through in the heat of battle.

Inosuke and Zenitsu practiced even harder and quickly mastered the technique as well.

Zenitsu Agatsuma always gives people the impression of being unreliable, but in reality, his abilities are no worse than Tanjiro's.

Attitudes can lie, but the body can't.

After seeing him sleepwalking in the courtyard practicing breathing techniques, Yuko understood that this guy's efforts were just a little strange, not that he was someone who was giving up.

During this time, for some unknown reason, the Lower Moon demons caused a series of disturbances, and the Pillars of the Demon Slayer Corps left empty-handed as a result.

One day, after Tanjiro and the others mastered the techniques of the regular way.

Yuko was discussing the intensity of breathing techniques with Shinobu Kocho inside the house. Shinobu was talking with a smile on her face when her eyes inadvertently glanced outside, and her face instantly went numb.

Before Yuko could even turn around, she sensed a disgusting malice coming from behind her.

She couldn't help but turn around and saw a man wearing a fire mask and a patterned kimono crawling in the shadows in the corridor, spying on them.

"..."

This guy is toxic.

As if he hadn't seen them at all, Haganezuka crawled forward, twisting his body to reach Ikuko's side, and reached out towards the Nichirin Blade placed on the tatami mat.

Just as they were about to succeed, a foot clad in a white stocking coldly stepped down.

……

Inside the room, Tanjiro glanced at Haganezuka, who was sitting trembling to one side after being disciplined by Ikuko, and said with a bead of sweat, "Mr. Haganezuka accompanied Mr. Tetsuanamori to deliver a sword to Inosuke."

Accompanying someone to deliver the knife?

Yu Zi glanced at him sideways.

"Eek!" Steel Tomb shuddered.

Wearing the same fire-man mask, Tetsuya Mori introduced himself: "My name is Tetsuya Mori, and I am the one who forges swords for Lord Inosuke."

"It would be my honor to be of assistance in the battle."

Yu Zi let out a long sigh and nodded to herself, thinking that there were still normal people out there.

"Lord Inosuke?"

Before Yuko could finish her reflection, a disturbance broke out nearby.

Under the puzzled gazes of the crowd, Inosuke went into the courtyard, picked up a stone, and began smashing it against the two brand-new Nichirin Blades until they were serrated.

"..."

After a moment of silence, Tie Xuesen suddenly roared, "I'm going to kill you, you brat!"

Fortunately, Tanjiro stopped him, otherwise Inosuke would have died a tragic death at the hands of the blacksmith.

What exactly are these people here for?

Yu Zi rubbed her temples, feeling a bit of a headache. Just as she lightly massaged her temples a couple of times, a pair of cold little hands suddenly touched her from behind.

Yuko looked up and saw Shinobu Kocho standing there, smiling as she lowered her head: "Yuko, would you like to try a professional doctor's technique?"
