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

Almost identical crescent blades collided in mid-air, canceling each other out.

Two years later, wearing that purplish-black outfit, Ji Guoyansheng reappeared before her.

"Upward...one..."

Looking at the numbers engraved in her pupils, Yuko slowly read them aloud.

Perhaps it was to better find the Blue Spider Lily, or perhaps it was because Yoriichi's existence made Muzan finally realize the importance of cultivating his personal guard.

The Twelve Ghost Months were thus created.

As the strongest person besides him, Kokushibo successfully took the position of Upper Moon One.

Yuko's gentle expression turned gloomy at a visible speed.

With six eyes, his facial expression was no longer discernible. Yan Sheng said calmly, "Yu Zi, you're going to die."

Iwakatsu's eyes easily saw through Ikuko's physical condition.

Yuko tightened her grip on the knife, her expression frighteningly calm.

"So what?" She subtly took half a step forward, blocking Namiko, who was trembling all over.

"Why won't you become a ghost?" Unlike most ghosts who have lost their memories of their previous life, Iwakatsu has completely retained his memories.

"My body will recover as soon as I become a ghost."

"The ultimate swordsmanship you seek is no longer a dream."

He couldn't understand why his sister was so resistant.

A shadow fell over Yuko's eyes: "So, is it acceptable to eat people for these reasons?"

"How many people have you... cough cough... eaten?" When Yuko spoke in a hurried tone, her lungs were prone to problems.

The strength of a demon is often directly proportional to the number of people it devours.

This statement is correct. Unless Muzan bestows blood upon them, eating humans is the fastest way for demons to become stronger.

After two years, Yan Sheng's aura became even stronger and more foul.

So much so that just standing in front of him, Namiko, who was not strong enough, felt short of breath and trembled all over.

This is not the kind of worldview a normal person should have, even in this dog-eat-dog world.

But Iwakatsu couldn't understand it.

As a samurai and a member of the ruling class, Iwakatsu was completely unable to understand Ikuko's emphasis on ordinary people.

Even when he joined the Demon Slayer Corps, Kokushibo's goal was not to slay demons and save people, but to surpass Yoriichi.

Unable to detect a trace of remorse on Iwakatsu's face, Yuko stared intently at him and said in a low voice, "Namiko, can you move?"

"Leave here and go down the mountain to seek help."

Hearing Yuko's voice, Namiko snapped out of her fright.

“But, Miss Yuko, you…”

Yuko interrupted, "That's not a demon you can handle. Only those who go down the mountain to contact the Demon Slayer Corps will have a chance."

Namiko hesitated for a moment, then nodded with tears in her eyes, "I understand. Please be careful."

"I'll be right back!"

While Ikuko and Iwakatsu were confronting each other, Namiko stormed out the door.

Yan Sheng made no move: "At a time like this, are you still thinking about others?"

Call for reinforcements? By the time reinforcements arrive, this matter will have long been over.

Yuko remained silent, simply keeping a watchful eye on him.

Just then, Yan Sheng moved, his ghostly figure rapidly approaching Yu Zi.

"So fast!" Yuko was shocked and was about to raise her sword to deal with it, but Iwakatsu walked straight past her.

His target is... Namiko!

Yu Zi's pupils contracted sharply, and she quickly turned around.

"Yan Sheng! You!"

This situation.

"Snow Breathing, Fifth Form, Snow Walk".

The snow-white figure approached Yan Sheng in the blink of an eye.

so slow……

Iwakatsu's speed is so slow...

In a daze, Yuko subconsciously thought of it.

But the situation had already changed in the blink of an eye, leaving her no time to think.

The next move of Snow Breathing was about to be unleashed, aimed straight at Iwakatsu's neck, but Iwakatsu seemed completely unaware and continued running forward.

Suddenly, a piercing pain shot through my lungs, as if someone had squeezed them hard.

Yuko's steps became unsteady for a moment, and after a few stumbles, the world in front of her seemed to tilt.

At this moment, she recalled Yan Sheng's strange behavior just now.

Is it by using the transparent world to see her breathing rate in her lungs and predict when her next attack will occur?

Yuko's wine-red eyes narrowed slightly as she watched Iwakatsu stab Namiko in the back.

It's as if you can see the next moment when Namiko's heart is pierced through from behind.

Yuko's wine-red eyes deepened...

Just as Yan Sheng calmly brought his long sword less than half an inch from the woman's back, an angry voice suddenly rang in his ears.

"Go away!"

Almost simultaneously, a flash of crimson appeared in the corner of his eye.

"When?!" A surge of shock rose in Yan Sheng's otherwise calm heart.

The snow-white blade flashed past his eyes, a severed arm was thrown high into the air, and blood splattered in mid-air.

Namiko sensed the movement behind her and instinctively turned around to see Ms. Yuko with an unprecedentedly gloomy expression, confronting the demon.

She gritted her teeth and charged forward headfirst.

She would only be a burden to Miss Yuko if she stayed here; she couldn't let Miss Yuko down.

Yan Sheng stood still, silently staring at the severed arm.

Regeneration... is so slow.

Does Snow Breathing really have such a strong effect on regeneration?

No, that's not the point.

He didn't understand how Yuko had gotten to his side in that instant.

If that knife was aimed at the neck...

Yuko held the knife in both hands, a dark look on her face: "Is this your answer to wantonly slaughtering humans?"

Yan Sheng controlled the regeneration of flesh and blood, and with focused concentration, he recovered completely in just a few seconds.

"See? Once you become a ghost, even losing an arm is just a minor injury."

"I didn't come to see you perform magic." Yuko's eyes remained gloomy as she raised her Nichirin Blade in a starting stance.

“I see…” Yan Sheng’s tone was slightly regretful as he stood facing off with his sword. “My name is… Kokushibo.”

The next instant, two figures, one in white and one in purple, collided.

“You will die, Yuuko.” Kokushibo effortlessly parried Yuuko’s attacks. “Even if your dream cannot be realized, is that alright?”

Yuko sneered, "You really think that becoming a demon will allow you to surpass Yoriichi?"

Kokushibo's eyes narrowed slightly.

"You should know that even if you become a ghost, you cannot transcend fate..."

Before Yu Zi could finish speaking, an indescribable sense of crisis instantly enveloped her entire body.

A transparent world unfolded before her eyes, and she saw that Kokushibo's whole body was tense, and his breathing rhythm became steady and powerful.

"Breathing of the Moon - Eighth Form - Moon Dragon Tail!"

Kokushibo stepped forward, and a huge blue-purple crescent moon, as vast as a galaxy, swept out, almost engulfing everything in front of him.

This is a sword type that Yuko has never seen before, and its power is unprecedented!

But Ikuko, who had seen through Kokushibo's muscle movements, was prepared and leaned back.

boom!

The giant crescent moon shattered the house behind her, and a bloodstain appeared on Yuko's forehead.

She flipped backward to steady herself and wiped the bloodstains from her forehead.

The residual force of the attack was enough to...
