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

"No matter how strong a person is, their heart is fragile."

"Once you grasp the weaknesses of the mind, people are nothing to fear," a man with the word 'dream' written on the back of his hand said flippantly on the train.

Yuko slumped to the side, her head tilted to one side, the hilt of her knife hanging limply in her hand, resting on the floor.

This woman's terrifying mental strength was indeed beyond his imagination, but the weakness of her mind could never be repaired.

Even though this woman almost perfectly resisted his Blood Demon Art, he, who had obtained Muzan's blood and understood the weaknesses of the mind, was enough for him to be momentarily distracted.

Ultimately, humans are such fragile creatures.

The children who had been pushed aside by Yuko scrambled up from both sides. One of the girls, holding a sharp weapon, gritted her teeth and walked toward Yuko.

Another person crouched down and tried to take the Nichirin Blade from her hand.

A man shouted softly, "Idiot, stop!"

Everyone shuddered and quickly stopped: "I'm sorry, I just..."

The man said ruthlessly, "This woman is not someone you can handle. Go and destroy the spiritual cores of the others."

"In that case, I'll let you dream on."

"Yes!" Upon hearing this, everyone smiled.

After everyone left, Ren Shou looked at Yu Zi, who was sleeping soundly to the side.

"This woman is in trouble..."

His mental strength is on a completely different level from other demon hunters.

Even a child with no murderous intent would probably wake her up if they approached.

But if we just leave her here, under the influence of that powerful mental force, she'll probably wake up soon.

There was no other way but for him to take the job.

Although it would divert some of his energy from his main body and slow down the train's fusion process, he couldn't rest easy until he dealt with this woman.

Fortunately, this woman's heart was not as strong as her spirit; just looking at her was enough to be infected by the sadness emanating from her.

Such a person has a heart as fragile as glass.

If we devote more energy to this, we might be able to deceive this woman's keen senses.

Nightmare can travel through the dreams of those affected without direct contact.

The Blood Demon Technique was unleashed, and a wisp of ghostly energy emanated from it.

Yuko's long eyelashes trembled slightly, but she remained still.

Great, it worked!

……

"You're amazing, Yuuko! I'm no match for you at all."

Iwakatsu, who had been knocked to the ground by Yuko, grinned with a face covered in dust.

Yuko reached out and pulled him up, smiling, "It's alright, brother, you're just not quite familiar with the breathing technique I use yet."

"With more practice, there will definitely be no problem."

A voice called from beside her: "Yuko, come quick and help me check why my Type 13 can't connect."

"coming."

Outside the courtyard, a young man wearing a black coat and white striped trousers, with the character "下" (xià) in his pupils, smiled as he watched everything.

"That's good. Just keep having sweet dreams."

A sinister smile appeared on Nightmare's lips as she turned and headed towards the outer perimeter.

Yuko turned around as if sensing something, and a bamboo grove appeared outside the courtyard, where a figure seemed to have disappeared.

it's wired……

Was there a bamboo grove outside her yard before?

Something feels off...

Yoriichi stepped forward and asked with concern, "Yuko? Why are you spacing out again?"

Yu Zi frowned slightly and shook her head gently: "It's nothing, it just feels... something feels off."

Yan Sheng followed over: "What's strange?"

Yuko hesitated before saying, "It's just that I feel... so happy..."

Her father, mother, and brother were all so gentle, so gentle that she felt it was a little unreal.

The father should be strict, and Yan Sheng should be competitive and jealous...

Yan Sheng chuckled, speechless. "What are you talking about? Isn't happiness a good thing?"

"is it?"

"Isn't that obvious? The most wonderful thing in the world is for a family to live happily together."

"I think so..."

……

Once it was confirmed that Yuko was already in a sweet dream, Nightmare felt much happier.

Once the core of the spirit is found, the demon hunter will become a cripple, at which point he can be easily killed.

Nightmare could sense the location of the spiritual core; all it needed to do was pass through this bamboo forest…

Suddenly, as Nightmare glanced casually at the bamboo forest, her pupils contracted sharply, as if she had seen some incomprehensible being, and the smile on her face instantly crumbled.

A young man dressed in a black kimono, with a faint, confident smile on his face, stood in the forest, accompanied by a beautiful servant.

“Lord Muzan…” Enmu almost instinctively knelt down and bowed his head deeply.

what happened?

Why is Muzan-sama here?

Muzan Kibutsuji had a faint smile on his lips: "I'm no longer interested in swordsmen who can use breathing techniques."

It really is Lord Muzan's voice!

Nightmare shuddered. Why is Lord Muzan here?

Isn't this that woman's dream?

What exactly is going on?

A murderous voice rang out from behind: "Kibutsuji Muzan, your death is imminent."

Who?

How dare they speak to Lord Muzan like that?

When Nightmare looked back, she saw two tall figures, one red and one purple, with strange markings on their faces, standing there.

It's that kid who was with that woman just now...

Before he could think any further, Muzan swung his arm, transforming it into a long whip, and swept it towards the two of them.

The two dodged to the left and right, their eyes fixed firmly on the enemy in front of them.

"Breath of the Sun..."

"Breathing of the Moon..."

Two dense slashes, one red and one purple, severed all of Muzan Kibutsuji's tentacles.

As the two swordsmen approached, Enmu, standing between them, faced the same fear that Muzan had once faced.

What flashed through my mind was...

"What do you consider life to be?"

Nightmare's expression was on the verge of collapse. The overwhelming aura pressed down on him like the sky was falling, making it hard for him to breathe.

Fortunately, he wasn't their target.

The immense pressure vanished abruptly after the two brushed past each other, and Nightmare looked back in terror.

The crimson figure charged forward and instantly severed Muzan's head from his body with a sword shape too sharp to see with the naked eye. Muzan could only hold his head up with his severed arm.

Faced with the attacks of the two swordsmen, Muzan Kibutsuji had almost no chance to fight back. He quickly split into thousands of pieces of flesh and exploded in an attempt to escape.

The crimson swordsman instinctively swung his blade, instantly slicing off 1,500 pieces.

Seeing that the remaining pieces of meat were about to escape, the crimson swordsman hurriedly called out, "Brother!"

"Breathing of the Moon..."

The purple swordsman wielded his purple longsword, unleashing a dense barrage of countless tiny crescent-shaped slashes that shattered the remaining three hundred-plus pieces of flesh.

Nightmare's eyes trembled violently.

What kind of beautiful dream is this woman having!

How dare they...
