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

"Uh...am I in hell?"

"What a strong guy..."

“Zenitsu…Inosuke…” Tanjiro’s eyes glistened with tears; he had almost thought he was going to lose everyone.

Just as he was so moved that he wanted to hug her, someone suddenly tugged at his clothes from behind.

Tanjiro turned around and saw Nezuko puffing out her cheeks, looking at him with a resentful expression.

Tanjiro froze for a moment, then waved his hand frantically, "I'm sorry, brother didn't mean to forget you..."

On the other side, Suma, embarrassed, grabbed Uzui Tengen's severed arm and looked at Ikuko: "Um, sister... could you...?"

Before she could finish speaking, the other two covered her mouth.

Mu Xu glared at her: "Shh, idiot, don't make a sound."

They certainly wanted Lord Tengen's arm to be put back in place, but he looked very unwell...

That's true, with so much blood lost, it's no wonder her complexion is pale.

“Give it to me…” Yuko shook her head, her face pale, and took the severed arm from Suma’s hand.

Uzui Tengen frowned: "Is it alright?"

“It was my oversight…” Yuko lowered her eyelids slightly, attached the severed arm to his shoulder, and began to repair it in silence.

She was too smug.

They thought that by defeating Upper Moon Three, they could sever half of Muzan's arm.

In Yuko's eyes, Muzan was an idiot who had power but didn't know how to use it at all.

He's a villain who's good for nothing except his strength.

She never expected Muzan to send Kokushibo directly... No, she should have expected it. Given Muzan's fear of Yoriichi, anything could happen.

It's her fault.

Just as Yuko was repairing Yuzui Tengen's arm, a red light flashed across the ground.

Uzui Tengen and Tanjiro were the first to react and looked up.

Two flying scythes, seemingly enveloped in blood-red light, spun and flew towards them.

Tanjiro glanced at his companions, who were either undergoing treatment or had just recovered, and gritted his teeth as he picked up his broken sword.

boom! !

A purple crescent-shaped slash instantly extinguished the red light.

Tanjiro looked on in astonishment, only to see Kokushibo calmly lower his hand.

"Lord Kokushibo? What are you doing?" A hoarse voice of Gyutaro sounded from behind.

Kokushibo said calmly, "You don't need to know."

Daki, standing on Gyutaro's back, complained, "Lord Muzan's order was to eliminate them all..."

Kokushibo's cold gaze swept over her, and Daki felt as if she had fallen into an ice cave.

This is not only suppression from superiors and subordinates, but also suppression of combat power itself.

Sweat trickled down the side of Gyutaro's face.

……

"Alright." Yu Zi withdrew her hand.

At this moment, Uzui Tengen's attention was completely off his arm; he was looking at the demons with a look of astonishment.

Yuko staggered, stood up, took a deep breath, and turned away with a calm expression.

Two people, ten eyes.

When the brother and sister stood in the same place again, nearly five hundred years had passed since their last meeting.

Yuko suddenly remembered that she used to mock him as a "six-eyed lemon spirit," but now she couldn't bring herself to say it.

"Why?" It was Kokushibo who spoke first.

Yuko cracked her knuckles: "What do you mean, 'why'? I should be the one asking that."

"..." Kokushibo was silent for a moment: "You still remember that incident, but you were about to die at the time, and this was the only way to save you."

Yuko touched the marks on her cheek: "I was destined to die anyway."

Even without lung problems, she wouldn't live past twenty-five after the marks are activated.

"I will die, and you should die too..."

They should have died during the Warring States period.

Tanjiro looked at Kokushibo with suspicion and uncertainty, trying to guess his identity.

He almost thought this person was Miss Yuko's brother who created the Breath of the Sun, but upon closer inspection, he realized that the person's name seemed to be Yoriichi.

The ghost just called out this name, so... is it someone else?

But they really do look so alike...

Ikuko had only told Shinobu about Iwakatsu.

The information about Kokushibo did not show their relationship.

Therefore, Tanjiro and the others were unaware of this.

Kokushibo fell silent again after hearing Yuko's words; he didn't understand why Yuko was so stubborn.

Just like Yuko doesn't understand, is defeating her own brother really that important?

It's so important that I'd rather give up my identity as a human being.

More than four hundred years later, the two people's minds have long since diverged into two completely different paths.

"You two can handle the two guys over there, right?" Yuko said calmly, looking at Kokushibo.

Uzui Tengen nodded firmly: "Yes, leave it to us."

He had already lost to that monster once and didn't want to lose a second time.

Yuko glanced at the broken sword in Tanjiro's hand, then took off her Nichirin Blade from her waist and tossed it over: "Those two are twin demons; they'll only die if their heads are cut off at the same time."

"Be careful."

Tanjiro took the Nichirin Blade: "Miss Ikuko..."

Yu Zi smiled slightly: "Didn't we already say that?"

"I will give you this sword after you master the Breath of the Sun."

"Now is the time."

She had wanted to give the sword to Tanjiro before, but Tanjiro refused because his sword was still usable.

Tanjiro's lips curled into a bitter smile. If it were before, he might have shamelessly answered yes.

but now……

Has he really mastered it?

Kokushibo looked at the black sword, and without a doubt, even after hundreds of years, he remembered it.

That was Yoriichi's sword.

How could they hand it over to that brat...

Kokushibo said calmly, "This brat is not even one ten-thousandth as good as Yorimitsu. Yuuko, you don't actually think that this level of swordsmanship is enough to defeat Lord Muzan, do you?"

"Your delusions are far too unrealistic."

Upon hearing this, Tanjiro instinctively gripped the hilt of his sword tighter.

There's no way to refute it...

"Targeting a child like this?" Yuko's lips curled up, a cold smile appearing in her crimson eyes. "What? Seeing a swordsman who can use Sun Breathing makes you so unhappy?"

"Thinking back to the embarrassing times when you could never beat Yoriichi?"

"You're still exactly the same as before..."

"The smell of jealousy is truly teeth-grinding."

It has to be said that this is what Kokushibo cares about most. Even though he had prepared himself mentally beforehand, he still couldn't help but be broken by Yuuko's words.

Kokushibo maintained a calm expression: "Your mouth is still as sharp as ever."

"Are you angry? It's really funny how you're trying to keep calm." Yu Zi sneered. "Your tone has sped up, you slow-moving old man."

As a samurai during the Sengoku period, Kokushibo displayed the demeanor of a superior in both etiquette and speech.

He pauses for a long time when speaking, but his pronunciation is very clear.

Everyone: "..."

That guy has such a sharp tongue.
