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

Muzan held a hostile attitude towards all other demons except himself.

Even Kokushibo, whom he called a collaborator.

If it weren't for expanding the search for the Blue Spider Lily, Muzan would never have had the idea of ​​turning other people into demons.

What reinforced this idea in him was the image of that monstrous swordsman from hundreds of years ago.

That is, the brothers of the two guys who are currently hanging in the sky and showing their deep sibling affection.

That monster... shouldn't even exist in this world.

Because of that encounter back then, Muzan Kibutsuji became even more cautious and almost never put himself in danger.

Aside from research, he delegated all tasks to his subordinates, and the Twelve Demon Moons system he established brought the power of the demons to its peak.

Conversely, the Demon Slayer Corps' forces were nearly wiped out by Yoriichi's departure.

Ultimately, compared to overcoming sunlight, the Demon Slayer Corps' hatred is nothing compared to him; at best, they're just an eyesore.

There has been no news about the blue spider lily, and research into overcoming sunlight has repeatedly failed.

Yuko, who suddenly appeared in his eyes, was like a ray of moonlight rising in the dark night, dazzlingly bright.

An barely suppressed excitement rose on Muzan's face as he called out, "Nekome!"

Nakime, who was sitting to the side acting as a song requester, paused for a moment while playing the piano, and then...

when! !

The sound of the pipa resounded throughout the entire Infinite City, even reaching Yuko's ears despite the passage of space.

Again!

Unable to break free from Kokushibo's restraints, Yuuko's pupils contracted slightly. What was this time...?

Another door opened beside Yuko's hand. Yuko felt the touch on her hand suddenly disappear. Her body, which had been able to support her, completely lost its balance and was pulled by Kokushibo down towards the bottom of the Infinite Castle.

It’s over.

Yuko's heart gradually quieted down, and an unnatural bitter smile appeared on her lips.

Eat her, overcome the cruelty of sunlight...

She couldn't think of anything else to do.

As a result... she ended up being the one who dragged the team down again...

If only I had known she would do that...

Suddenly, a pair of slender arms reached down from the open door and grabbed Yuko's fingers, which had already lost their will to live and were slightly curled up.

The sudden pulling sensation made Yuko look up in surprise.

What came into view was Shinobu Kocho's face, drenched in sweat and looking extremely nervous.

The girl's breathing was rapid, her shoulders heaving with each breath, and beads of sweat dripped from her chin. Her purple hair, damp with sweat, clung to her cheeks, and the purple butterfly pattern on her face added a touch of alluring beauty to her features.

“Endure…” Yu Zi’s eyes trembled slightly.

Is it to endure?

Why is she here?

Yuko's previously dormant heart stirred anew.

Shinobu Kocho spoke tremulously, "Finally... I finally made it."

She was so close, so close, to losing Yuko.

After receiving news of the attack on the sword-forging village from the raven, she rushed over without stopping, her heart filled with unease.

Finally, she caught up.

Who?

Kokushibo's gaze followed, fixed on the unfamiliar figure, whose aura...

Is it a pillar?

It even awakened its markings.

"I'll pull you up right now," Butterfly said, panting heavily, her face showing signs of difficulty.

She was already quite weak, and now she had to hold onto not only Yuko but also Kuroshibo.

Even with her markings activated, she still had a hard time pulling Yuko up.

Butterfly gritted her teeth, and the veins on her forehead and arms were clearly visible.

I won't let go.

She absolutely refuses to let go.

Ikuko saw Shinobu's predicament and looked down at Kokushibo: "Let go!"

"Yuko! You belong on my side!" Kokushibo roared.

Yu Zi was sweating profusely with anxiety: "Why are you so agitated? Let go of me!"

踹！

踹！

I can't kick it!

This guy's body is as hard as a rock!

Muzan's face was terrifyingly grim: "Nakome!"

when! ! !

However, nothing happened.

"Lord Muzan!" Nakime suddenly shouted.

Above the two gates in the sky, the sun slowly rose, and a ray of sunlight pierced through the tall trees and shone into the Infinite City.

The doors began to crumble, and the houses within the Infinite City also began to show signs of disintegration.

"Yuko, let go! You'll die!" Kokushibo noticed this and shouted immediately.

"..."

Bright sunlight streamed through Shinobu Kocho and shone onto Ikuko's profile, making her fair skin seem to glow in the sunlight.

Kokushibo was stunned for a moment.

……

Sunshine, that woman...

We've overcome the sunlight!!!

After a moment of stunned silence, a hint of madness appeared on Muzan Kibutsuji's handsome face.

"Nakime! Pull that woman down!" Muzan's face was filled with unprecedented excitement.

“Lord Muzan…” Nakime sat there blankly.

I really want to say something.

I cannot do it.

Even the most powerful blood demon magic is ineffective under sunlight.

In other words, Muzan is the boss, otherwise Nakime would have complained that this guy isn't very smart.

Seeing that Nakime was useless, Muzan clicked his tongue in dissatisfaction, raised his pale, sickly arm high, and instantly it transformed into a long whip of flesh and blood, shooting towards Yuko in mid-air.

……

Sunlight streamed through Yuko and fell on Kokushibo's chest, instantly scorching his muscular body.

opportunity!

Yuko's eyes lit up, and she grabbed Kokushibo's hand tightly.

Please don't let go of her hand, brother!

cough!!

A whooshing sound suddenly came from the air.

what?

Yuko looked down and saw the long whip of flesh and blood, constantly scorched by the sun, relentlessly shooting towards her.

As Yuko's expression changed slightly, Kokushibo forcibly tore off his own arm and silently let his body fall downwards.

Muzan Kibutsuji had no interest in Kokushibo's life or death; he was focused and longing as he gazed at the sky.

Almost there! Almost there!

That woman!

Hope to overcome the sun!

As Kokushibo let go, Shinobu Kocho felt a sudden lightness in her grip, and then, as if she had inexhaustible strength, she pulled Ikuko up.

The long, fleshy whip relentlessly chased upwards.

The dazzling sunlight and the doors suddenly vanished, leaving only the dilapidated and ruined Infinite City.

The long whip of flesh and blood lost its target and came to a sudden stop.

"Narume!!!"

A sharp explosion rang out within the Infinite City.
