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

Kokushibo released his grip without expression.

Yu Zi collapsed to the ground, struggling to support her neck. Her face contorted in rage, veins bulging on her forehead and neck, and her eyes bloodshot.

Something was injected into her body through Iwakatsu's fingers.

At this moment, Yuko felt restless all over, as if her blood was boiling, an indescribable feeling.

As Kokushibo slowly walked towards Namiko, who had crawled to the doorway, he said calmly, "The stronger a person is, the longer it takes for them to transform into a demon. You'll just stay here obediently for the next few days."

It took him three full days to transform into a demon, while Yuko's talent was no less than his.

Noticing the movement behind her, Namiko turned around in terror, letting out a mournful whimper, straining her elbows and knees even harder, looking utterly disheveled.

Without a trace of emotion in his eyes, Kokushibo dragged her back.

"Ah!" Namiko writhed in terror.

Kokushibo casually threw her to the ground, broke the branch of the Demon Blade in his hand, stepped on Namiko's hands and feet, and pinned all four of her limbs to the ground.

"Ah~"

Namiko's screams were incessant.

Yuko stared at the scene with bloodshot eyes: "Yan Sheng..."

The words that Ikuko squeezed out from between her teeth revealed a rare hint of anger in Kokushibo's voice.

Surprisingly, he was in a good mood.

You bastard!

Despite Yuuko's insults, Kokushibo ignored her and left directly.

Yuko lay on the ground in agony, feeling her heart beating faster and faster, as if something inside her was changing.

That was a change at the micro level.

Namiko's painful groans reached her ears, and Yuko subconsciously glanced to the side, finding Namiko's current state incredibly alluring.

It wasn't until her saliva dripped onto the floor that Yuko suddenly realized what was happening.

She turned her head away, desperately trying to suppress the pounding in her heart, and dug her fingers deep into the ground with a ferocious grin, calling out with difficulty, "Namiko... get up..."

She finally understood why Iwakatsu did this; his purpose was to make her eat Namiko herself after she became a demon.

Even without Yuko's voice, Namiko, who witnessed the changes in Yuko's body, was terrified and wanted to pull out the blade stuck in the back of her hand.

But with her tendons in her hands and feet severed, she couldn't muster any strength and could only watch helplessly as blood flowed from her body.

It's almost dawn...

Yuko gritted her teeth, trying to climb out of the door, but the effects on her body prevented her from doing such a luxury; Muzan's cells were reshaping her body.

Yuko curled up into a ball, put her hands in her mouth, and tried her best to hold on to her true self.

Her hand was covered in blood from being bitten, but her consciousness was slowly fading away.

……

I don’t know how much time passed.

When Yuko suddenly woke up, the moon was full outside, and the hazy moonlight poured in through the door, illuminating the room.

Yuko gasped for breath and looked down at her hands.

Her once snow-white nails now looked as if they had been manicured, turning black, and the back of her hand, which she had bitten until it was bloody and mangled, was as smooth as soap under the moonlight.

She became a ghost.

But she seems to still possess an independent will.

After a moment of stunned silence, Yuko touched her cheek with a hint of panic. Fortunately, her nose and eyes were still her nose and eyes, and she didn't have the distorted appearance that Iwakatsu had.

Immediately afterwards, her somewhat recovered brain compelled her to look towards Namiko.

Namiko was covered in blood and lay motionless on the spot. The blood flowing from her hands and feet had already congealed. Judging from her disheveled appearance, one could imagine how desperately she had struggled.

Yuko's saliva involuntarily flowed from her mouth, and her eyes were fixed intently on Namiko's body.

Namiko is not dead yet. The demon's perception is terrifyingly strong; Ikuko can even hear her faint heartbeat.

tick tock...

It was as if a Manchu Han Imperial Feast was laid out in front of a starving person, causing their mouth to water uncontrollably.

But she could also clearly feel that she could control this desire.

Yuko is afraid of becoming a ghost, not just because ghosts eat people.

Furthermore, after becoming a demon, one's will is distorted, and the Demon King possesses the ability to read minds.

Once Muzan has read her mind, he will be able to overcome sunlight ahead of time and become truly invincible.

Yu Zi turned her head away from her, her rationality slowly returning, and her drool stopped.

Was she able to overcome this impulse because she was special?

Is it because she doesn't belong to this world?

Or is it because of the blue spider lily?

She clearly only saw it.

……

It's wild vegetables!

Yuko suddenly realized.

She and Yoriichi once visited Tanjiro's house, where they were treated to wild vegetables for several days. Were those blue spider lilies among them?

Yuko fell into deep thought.

Nezuko was able to overcome her urge to eat people, thanks to Tanjiro's desperate cries, but the blue spider lily was the most crucial condition.

Otherwise, why would she have to overcome it all by herself?

“Kibutsuji Muzan…” Ikuko uttered the words somewhat awkwardly.

She remembered that there was a curse in Muzan's blood that would kill any demon who spoke his name.

After waiting for a while, nothing unexpected happened.

She could clearly sense that her current situation was beyond Muzan's control.

Does this mean she became the second demon, after Tamayo, to successfully break free from Muzan's control?

Yu Zi breathed a sigh of relief.

Because she had seen the topic of the Demon Slayer Corps defeating Muzan purely through plot points more than once.

If Muzan were to truly hear her thoughts, he would be invincible even before the story begins.

After assessing her own condition, Yuko quickly crawled toward Namiko.

Saliva was being secreted unconsciously, and all her senses were telling her that the food in front of her was delicious.

Yuko suppressed her inner desires and carefully pulled the blades out of Namiko's hands and feet.

"Hmph~" Namiko groaned unconsciously, her brows furrowed.

She was tortured beyond recognition by Kokushibo, but at least she survived.

This won't do; we need to take her to the doctor right away.

Almost the instant this thought arose, Yu Zixin's mind became clear, and she instantly understood her Blood Demon Art.

It's like an innate talent that comes to mind unexpectedly.

Her Blood Demon Art... can save lives!

Yuko picked up the demon blade that had been thrown aside, cut her wrist, and smeared the blood onto Namiko's wound.

Namiko's wounds were healing at a speed visible to the naked eye, as if a demon were regenerating its severed arm.

Yuko's eyes lit up.

That ability!

This is so useful!
