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

Muichiro broke out in a cold sweat, the image he had seen lingering in his mind.

What kind of attack was it?

The broken parts of Yoriichi Type 0 were scattered all over the ground, and an old Nichirin Blade fell out of its body.

Xiaotie looked utterly dejected: "Ah! My Yoriichi..."

Before he could finish speaking, Kokushibo's calm voice rang out.

"Not even one ten-thousandth of the chance."

Kokushibo calmly put down the illusory cry god.

"Mmmm~"

In the still of the night, a sound of swallowing saliva, rather unhelpful, could be heard.

Upon hearing Kokushibo's voice, Kotetsu remembered that there was a monster in front of him, and he collapsed to the ground, trembling uncontrollably.

Monster...

Noticing the movement beside him, Kokushibo slowly turned around.

Muichiro tensed up instantly. He hadn't even had time to get used to the new sword he had just received when he was already on high alert with a serious expression.

Muichiro glanced at his wrist out of the corner of his eye, his body trembling unconsciously.

The sense of oppression is very strong.

This monster... I need to get serious.

Muichiro forced himself to suppress his fear and said in a low voice, "Get away from here."

Xiao Tie wanted to walk, but his legs wouldn't obey him at all.

Fortunately, Kokushibo's aura was only directed at Muichiro, and he ignored the two swordsmiths.

Xiao Tie's body was overwhelmed by fear simply because he glanced at it too long.

Since Tiexue Sen was still able to move, he quickly ran towards Xiao Tie, picked him up with one hand, and tried to make a run for it.

……

Kokushibo suddenly looked into the distance.

Ok?

The aura of the jade pot... has vanished?

Was he killed by someone?

As Upper Moon demons, all of them possess a strong bloodline of the Demon King, so even if they are far apart, sensing each other is not a problem.

It seems I can't dawdle any longer; I have to complete Lord Muzan's orders first.

In Muichiro's field of vision, Kokushibo suddenly moved.

So fast!

My eyes can’t keep up!

Despite Muichiro's heightened nerves, he couldn't see Kokushibo's movements at all.

Is an attack coming?

Which side is it?

A gust of wind brushed past him, and Muichiro's eyes widened slightly.

"Oh no!" Muichiro looked anxiously behind him.

Kokushibo's back overlapped with Tetsuya Mori's back. Kyokushin raised his sword high, without any fancy sword skills, just a swift and decisive strike like slaughtering cattle and sheep.

“Stop…” Muichiro blurted out instinctively, he had already reacted instinctively.

He was simply too slow.

The disparity in strength made it impossible for him to protect the others from this monster.

He had ignored the monster before, but if they had actually fought, he probably would have died countless times already.

Powerless.

Such words appeared in Muichiro's mind.

In that instant, time seemed to slow down.

He seemed to recall past events.

It was during...the battle with Yuko.

He asked, "Why can't I awaken my markings? Is your method wrong?"

Immediately afterwards, Yuko gave a smile that was hard to tell whether it was funny or helpless.

"Sometimes having too good a mindset isn't a good thing."

Muichiro tilted his head: "What do you mean?"

After he asked that question, a look of worry appeared on Yuko's face.

"You'll probably understand when you're truly in danger, but I don't know if it'll be too late..."

……

It's getting in the way.

Standing behind Tessaku Mori, who was completely unaware and still running forward with his head down, Kokushibo swung his sword down expressionlessly.

The next moment, you'll see blood splattering everywhere.

At that moment, a chill ran down my back, and an unexpected gust of wind rang out from behind me.

Kokushibo turned around in surprise, the blue tip of his blade coming into view.

I actually made it?

In this brief exchange, Kokushibo believed he had thoroughly grasped the strength of his descendant.

Therefore, he was certain that, given his previous state, Muichiro would definitely not be able to catch up with his attack.

Has the speed increased?

Although somewhat surprised, the speed of the improvement did not put any pressure on Kokushibo. He simply tilted his head slightly and let the slash graz his face.

The stab missed.

The two were inches apart, and Kokushibo saw the markings on Muichiro's face clearly: "Marks? You really are..."

Without wasting words, Muichiro forcibly stopped his movement after his thrust missed, and turned the blade to slash horizontally at Kokushibo's neck.

Kokushibo's figure suddenly disappeared.

"Too fast!" Muichiro gritted his teeth, not daring to relax in the slightest when facing such a formidable enemy.

"As expected of my descendant, he has already awakened his markings at the young age of fourteen."

Kokushibo's words still came out from behind Muichiro.

Watching the two disappear into the woods, Muichiro breathed a sigh of relief, then turned around with a sullen expression: "How many more times are you going to say that?"

"Even if it were true, hundreds of years have passed. How could your blood still be in my body?"

Are they markings?

No wonder he felt his speed was a bit unnatural and his body was unusually light.

……

Kokushibo remained silent.

"Is that so? Is that what you think too?" A calm, imposing voice rang out, and Kokushibo silently raised his sword.

Whether it's Yuko or the descendant I'm meeting for the first time.

What's so bad about becoming a ghost?

They found the village of forging knives and met their descendants.

Although he didn't care about the rise and fall of the adopted country when he chose to leave home, he was able to find out that he had descendants after hundreds of years.

Kokushibo was in a good mood; this was the second piece of good news that made him happy, after learning that Yuuko was still alive.

It was supposed to be double the happiness, but unfortunately, not a single thing went smoothly.

Kokushibo's rare moment of joy had been almost completely worn away.

Since they do not want to become demons, and do not want to be used by Lord Muzan.

Then...

Die.

Kokushibo's eyes turned cold as he slowly drew his sword.

Slightly ~

The blade made a soft rustling sound as it rubbed against the scabbard.

A terrifying aura emanated from Kokushibo's body, causing the surrounding trees to rustle as if intimidated by this powerful force.

Facing this powerful aura head-on, Muichiro felt a chill run through his entire body.

dead.

will die.

He absolutely cannot dodge this strike.

This is... Upper Moon One's true power...

That guy was just playing around...

Faced with this awe-inspiring aura, even Muichiro's movements became somewhat stiff.

For the first time, Kokushibo adopted a stance, lowering his body and exhaling a faint breath.

Muichiro was on high alert.

Focus, focus.

We have to get past it.

……

As if overwhelmed by intense pressure, as if in a moment of distraction, Kokushibo's figure had vanished from the spot.

I can't see it!!!

Muichiro's eyes darted left and right, trying to find any trace of Kokushibo.

"Breath of the Moon - First Form - Dark Moon - Night Palace!"

A dignified voice rang out steadily.

And the location where he appeared was...

in front of you.
