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

Muzan's voice was filled with anger, yet within that anger lay an indescribable sense of grievance.

It's as if she's the perpetrator and Muzan is the victim.

So, isn't this guy the one with the problem in his head?

No, no, the statement that Muzan has a problem with his head is not a question, but a statement of fact.

Faced with Yuko's calm retort, Muzan felt his head throbbing with blood.

That's not what he meant at all!

This woman is deliberately mocking him!

If Yuko knew his thoughts, she would probably be completely confused and think that Muzan was indeed seriously ill.

Muzan was filled with anger and resentment.

For hundreds of years, first that monster... and now this woman...

If he had known things would turn out this way, he shouldn't have agreed to Kokushibo's request in the first place.

What good would it do him if this woman became a ghost?!

Overcoming sunlight?

If Muzan had at least a sliver of hope that Yuko had brought him, then this woman was indeed a good person to save him back then.

Now all that's left for him is regret.

This woman's Blood Demon Art has nothing to do with overcoming sunlight. Perhaps she found the legendary Blue Spider Lily, or perhaps she found another method, or maybe it's that woman, Tamayo...

Muzan never doubted the woman's medical talent. If she hadn't run out of time, she could have cured her own illness. Otherwise, Muzan wouldn't have wanted to take Tamayo as his personal attendant.

Regardless of the circumstances, Muzan's feelings towards Ikuko are now reduced to nothing but resentment.

Since this woman was able to overcome the sunlight, it means that the method to overcome the sunlight truly exists. Even without this woman, he would have found a way to overcome the sunlight sooner or later.

Now, the grotesque scar on his chest with slight scorch marks is relentlessly eroding his sanity.

The breath of the sun...

The breathing technique, when used to strike the demon, left a burning pain that was unbearable for the demon.

Centuries later, the things left behind by that monster were reflected on him once again.

This guy is angry.

Looking at Muzan's unpredictable expression, full of resentment and anger, Yuko thought to herself.

To be honest, the injury looks serious, but for Muzan, it's nothing as long as he's not facing the sun directly.

Even the temperatures of the rising and setting sun made Yuko doubt whether they could effectively harm this guy.

Powerful demons often survive longer than weaker demons when exposed to sunlight.

Yuuko didn't know what Muzan was thinking, nor did she really want to know.

Yuko's golden eyes narrowed slightly, and the blade gleamed silver in the moonlight as she slashed towards Muzan's neck.

Muzan's current condition is not good; his body has suffered damage. He must maintain this opportunity and create a perfect chance for Tamayo.

In layman's terms, it means to strike while the iron is hot.

However, Yuko was constantly thinking about how to deal with the enemy next.

because……

A strangely shaped weapon was already aimed at her neck from behind.

That bastard Kokushimona, as the older brother, actually dared to ambush his younger sister?

You heartless bastard.

Why can't we wait until she cuts Muzan down and have a fair samurai duel?

Tsk.

Sensing the approaching presence of Sheng Ren behind her, Yu Zi keenly observed Muzan's writhing flesh.

Her regeneration speed is fast, although it can't compare to the normal recovery speed of the Upper Moon Demon Moon. But this is a wound left by the Breath of the Sun, and her sword form and movements are perfectly fine.

Is it because the breathing is not precise enough?

As expected, a mediocre person is just a mediocre person. If they insist on developing in areas they are not good at, they will never reach the top.

In just a moment, Yuko gave up resisting.

At this point, to avoid Kokushibo's attack, Muzan must be allowed to escape.

Muzan was frightened by the sword shape of the Sun Breathing technique; such an opportunity is unlikely to come again.

Ignoring the approaching demon blade behind her, Yuko raised her Nichirin Blade high and slammed it down, as if she wanted to split Muzan in two.

puff! ! !

At the critical moment, Muzan avoided the blow that was aimed directly at his head, letting his shoulder take the hit.

No, I didn't completely bear it all.

The Nichirin Blade severed Muzan's ear, embedding itself deep into his lung from his collarbone, before being stopped by his swollen, purple hand with bulging veins, preventing it from penetrating any further.

"Damn it!!!" The scalding red blade pierced his body, making a sizzling sound like it was being roasted.

Muzan's face turned red as he strained, his fingers gripping the Nichirin Blade and wrestling with Yuuko. His eyes were bloodshot and he looked like a demon, a far cry from his initial elegance.

He was restrained.

Before Yuko could even show a look of joy, out of the corner of her eye, the demon blade extended from her side and slashed horizontally across her neck.

After the blade sank into her neck, the feeling of her head being about to be ripped off disappeared; the force of the blade was much lighter than she had imagined.

However, in the blink of an eye, as if the last vestige of emotion in the wielder's heart was being extinguished, the demonic blade accelerated a second time, severing her head without any resistance.

Did it work?

Kokushibo's movements were somewhat stiff; he didn't know what he was thinking.

But he instinctively hoped that Yuko had successfully overcome her neck weakness by overcoming the sunlight, while on the other hand, he could not allow Muzan to be harmed.

Just as Kokushibo was hesitating and wavering.

"That hurts, you bastard!"

Yuko looked up at Kokushibo behind her with her head still in mid-air and muttered something under her breath.

If you're going to chop her up, don't hesitate! Is this bastard deliberately trying to torture her?!

Kokushibo paused for a moment, then inexplicably breathed a sigh of relief.

Blood gushed out from Yuko's neck, and an astonishing burst of blood light erupted, blooming like a crimson flower. The petals, composed of blood, spun and unfolded, forcing Kokushibo to retreat.

But amidst this all-out attack, a hidden passage, just wide enough for one person to pass through, was left behind.

well done!

Tamayo approached with cold sweat beading on her forehead, not daring to make any too violent movements, lest she be unable to effectively suppress Muzan.

Now, the aura emanating from Ikuko has obscured Tamayo's presence.

Tamayo's pace quickened, and in a final burst of running, she charged toward Muzan.

"what?!"

Kokushibo suddenly noticed that the surrounding air was being disturbed. He looked in surprise but saw nothing. However, he knew that there was something wrong with the airflow just now.

That direction is... bad!

Sensing the surrounding air being disturbed, Yuko, whose head had mostly recovered, turned her head but did not see Tamayo.

Can't you even see it from this distance?

There's a reason why Muzan would have his downfall.

The Demon King, being the source, was unable to effectively suppress the birth of Blood Demon Arts, and could only try to restrain it through blood cells.

Yuko maintained her wrestling motion with Muzan, forcing Muzan to use both hands to slowly lift her Nichirin Blade.
