Kokushibo expressionlessly released his grip.
Yuko collapsed to the ground, struggling to clutch her neck. Her face twisted grotesquely as veins bulged across her forehead and neck, and her eyes filled with blood vessels.
Something had been injected into her body through Kokushibo's fingers.
At that moment, Yuko felt restless all over, as if even her blood were boiling. It was an indescribable sensation.
As Kokushibo slowly walked toward Namiko, who had crawled to the doorway, he said calmly, "The stronger a person is, the longer it takes to turn them into a Demon. Stay here obediently for the next few days."
It had taken him a full three days to transform into a Demon, and Yuko's talent was no inferior to his.
Sensing the movement behind her, Namiko turned around in terror and let out a muffled, mournful cry. She pushed harder with her elbows and knees, looking utterly wretched.
Kokushibo's eyes held no emotion as he dragged her back.
"Ah!" Namiko twisted in terror.
Kokushibo casually threw her onto the ground, snapped the blade of the Demon Blade in his hand, and pinned Namiko's hands and feet to the floor.
"Ah~"
Namiko's screams rang out without end.
Yuko stared at the scene with bloodshot eyes. "Kokushibo..."
Kokushibo rarely heard such anger in the words squeezed through Yuko's clenched teeth.
His mood unexpectedly improved.
"You bastard!"
Kokushibo ignored Yuko's curses and left directly.
Yuko lay painfully on the ground. She could feel her heartbeat growing faster and faster, as if something inside her body were changing.
It was a transformation on a microscopic level.
Namiko's painful moans reached her ears. Yuko subconsciously glanced over and found Namiko's current state incredibly alluring.
Only when drool began dripping onto the floor did Yuko suddenly come to her senses.
She turned her head away and desperately suppressed the stirring in her heart, her five fingers digging viciously into the floor as she cried out with difficulty, "Namiko... get up..."
She finally understood why Kokushibo had done this. His goal was to make her eat Namiko herself after turning into a Demon.
Even without Yuko's warning, Namiko, who had witnessed the changes in Yuko's body, was already trying in terror to pull the blade from the back of her hand.
But the tendons in her hands and feet had been severed, leaving her unable to exert any strength. She could only watch helplessly as blood flowed from her body.
Dawn was almost here...
Yuko gritted her teeth and tried to crawl outside, but the effects her body was undergoing made such a luxury impossible. Muzan's cells were transforming her body.
Yuko curled into a ball, stuffed her hand into her mouth, and desperately clung to her original self.
The back of her hand was bitten until it was covered in blood, yet her consciousness continued to fade bit by bit.
No one knew how much time had passed.
When Yuko suddenly awoke, the moon outside was full. Misty moonlight poured through the doorway and illuminated the room.
Yuko gasped heavily and lowered her head to look at her hands.
Her originally snow-white nails now seemed to have been manicured, turning black. Even the back of her hand, which she had bitten until it was a bloody mess, had become as smooth as soap under the moonlight.
She had turned into a Demon.
But she seemed... to still possess an independent will.
After staring blankly for a moment, Yuko touched her cheek with some panic. Fortunately, her nose was still a nose and her eyes were still eyes. She had not developed a twisted appearance like Kokushibo's.
Then, her partially recovered mind drove her to look toward Namiko.
Namiko was covered in blood and lay motionless where she had been. The blood flowing from her hands and feet had already congealed. From her miserable appearance alone, one could imagine how desperately she had struggled.
Saliva unconsciously pooled in Yuko's mouth, and her eyes stared fixedly at Namiko's body.
Namiko was not dead yet. A Demon's senses were terrifyingly powerful; Yuko could even hear her faint heartbeat.
Drip, drip...
It was as if a sumptuous feast had been placed before a starving person. Saliva kept spilling from her mouth.
But she could also clearly feel that she was capable of controlling this desire.
Yuko had feared becoming a Demon not only because Demons ate people.
It was also because, after becoming a Demon, one's will would be distorted, and because the Demon King possessed the ability to read minds.
If Muzan read her thoughts, he would be able to overcome sunlight ahead of time and become truly invincible.
Yuko turned her head away and stopped looking at her. Her reason slowly returned, and the drool stopped flowing.
Could she overcome this impulse because she was special?
Was it because she did not belong to this world?
Or was it because of the Blue Spider Lily?
She had clearly only seen it before.
It was wild vegetables!
Yuko suddenly realized.
She and Yoriichi had once stayed at Tanjiki's home as guests. Tanjiki's family had treated them to wild vegetables for several days. Had those included the Blue Spider Lily?
Yuko fell into deep thought.
Nezuko had been able to overcome her desire to eat humans because of Tanjiro's desperate calls, but the Blue Spider Lily had been the most crucial condition.
Otherwise, why would she alone have been able to overcome it?
"Kibutsuji Muzan..." Yuko recited the name with slight awkwardness.
She remembered that there was some kind of curse in Muzan's blood, one that caused Demons who spoke his name to perish from the curse.
After waiting for a moment, nothing unexpected happened.
She could clearly sense her current condition. She was not under Muzan's control.
Did this mean she had become the second Demon after Tamayo to successfully escape Muzan's control?
Yuko let out a long breath from the bottom of her heart.
She had seen the claim more than once that the Demon Slayer Corps' victory over Muzan had relied entirely on plot armor.
If Muzan really heard her thoughts, there would be no need to wait for the story to begin. Muzan would already be invincible.
After confirming her condition, Yuko hurriedly crawled toward Namiko.
Saliva unconsciously filled her mouth, and every sense in her body told her that the food before her was extremely delicious.
Yuko restrained her desire and carefully pulled the blades from Namiko's hands and feet.
"Mm~" Namiko moaned unconsciously, her brows tightly furrowed.
Kokushibo had tormented her until she was barely recognizable, but at least she had survived.
This wouldn't do. She had to take Namiko to a doctor as soon as possible.
Almost the instant this thought arose, Yuko's mind opened up, and she immediately understood her Blood Demon Art.
It was like a talent she had been born with, suddenly coming to her without warning.
Her Blood Demon Art... could save people!
Yuko picked up the Demon Blade she had tossed aside, cut open her own wrist, and smeared the blood over Namiko's injured areas.
Namiko's wounds began healing at a visible speed, just like a Demon's arm regenerating.
Yuko's eyes lit up.
What an ability!
It was incredibly useful!
