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

“Yushiro, you mustn’t be rude,” Tamayo’s serene voice rang out.

"But Lady Tamayo, we are demons, how can we go to the Demon Slayer Corps and walk into their trap?"

Tamayo shook her head: "Since Ikuko says so, then nothing will happen."

Yushiro was so anxious he was at his wits' end; that woman was too cunning!

She dared to talk nonsense because of Lady Tamayo's trust in her.

"You wouldn't guess he's a guy with hundreds of years of experience," Yuko rubbed her temples, ignoring the boisterous Yushiro beside her, and looked at Tamayo:

"The current head of the Demon Slayer Corps is named Kagaya Ubuyashiki, and he is a person with great personal charisma."

“I contacted him two years ago, and he readily accepted my identity.”

A flicker of surprise crossed Tamayo's usually calm eyes as she exclaimed, "There really are people like that?"

"Yes, without a doubt, that family head is on our side."

Tamayo nodded slightly: "I understand. Let's set off tomorrow night then."

"Yushiro, please go and pack your luggage first."

"Lady Tamayo~" Yushiro hesitated, then could only nod. "I understand."

After Yushiro left, Tanjiro opened his mouth, hesitated, and said, "Um, Miss Tamayo..."

Zhu Shi looked in the direction of the sound.

"Is there a way to turn a ghost back into a human?"

Tamayo calmly replied, "Yes."

Tanjiro's expression shifted slightly, and he quickly asked, "Then..."

Tamayo interrupted, "No matter what kind of injury or illness it is, there will definitely be corresponding medicines and treatments."

"However, at this stage I am unable to turn a ghost back into a human."

"However, I will definitely work hard to find a treatment."

Yu Zi's lips twitched. Isn't this just nonsense literature?

When did Tamayo learn this trick?

“Speaking of which, Yuko.” Tamayo suddenly changed the subject, calling out Yuko’s name as she turned and opened a drawer.

Yuko asked in confusion, "What?"

Tamayo turned around, holding a syringe in her hand: "Your blood should be very useful."

"...Be gentle."

Thanks to technological advancements, things that were impossible in the past are now possible.

By using sophisticated instruments such as microscopes, it is possible to observe changes in cells in the blood.

Someone like Yuko, who overcame sunlight despite being a demon, is an excellent experimental subject.

……

On the other side, in the bustling city, Muzan Kibutsuji, who looked remarkably like Michael Jackson, gently gave a few words of advice to his wife and daughter before turning and entering a small alley.

After dealing with a few drunkards, Muzan Kibutsuji snapped his fingers.

What are your orders?

Two demons, a man and a woman, appeared out of nowhere in front of Muzan and knelt down.

Muzan's expression shifted between anger and uncertainty: "Take the head of the demon slayer who wears the confetti-like earrings on his ears, understand?"

"As ordered!"

Just as the two demons were about to leave, Muzan suddenly spoke up: "Wait."

The two ghosts bowed their heads respectfully.

Muzan recalled the figure wearing a straw hat, with only long hair flowing out.

In a daze, he felt an uncanny resemblance to the figure who had wielded a crimson blade and charged straight at him hundreds of years ago.

At that moment, every cell in his body trembled.

That woman...that boy...

What does it have to do with that monster?

"Beside the demon hunter was a woman with long red hair, whose head was brought along as well."

"Yes, sir!" A qualified subordinate is one who unconditionally accepts any instruction from their boss.

"With your current strength, you are probably no match for that woman." Muzan lowered his head, his eyes coldly looking at the two demons. "Be honored, I will bestow upon you the power of the Twelve Demon Moons."

Upon hearing this, both ghosts couldn't help but raise their heads in delight.

A fleshy tentacle tore open from Muzan's body and swiftly burrowed into the necks of the two demons.

With a wriggling of the tentacles, as if something was being injected into their bodies, both ghosts lay on the ground with ferocious expressions, their turbid auras expanding continuously.

A moment later, the two ghosts looked up with great joy.

"Thank you for the blood, sir!"

"Go, I want to see their heads."

"As ordered!"

As the two demons vanished with a whoosh, Muzan's calm lips suddenly parted into a disdainful grin.

"Tsk, it's a pity that my Upper Moon hasn't arrived yet. With one person here, what's there to fear from that woman?"

They even want to waste his blood to cultivate two useless people.

Muzan's face was terrifyingly gloomy.

That monster... could it have descendants?

Impossible. He and Kokushibo clearly slaughtered all those who knew the truth back then.

Even if the two demons, both of whom possess the strength of a Lower Moon demon, cannot defeat that woman, they should at least try to understand her situation.

Even after hundreds of years, the shadow cast by that monster has not yet faded from his memory.

……

"Okay, let's store these for now."

Tamayo pulled the pillow from Ikuko's arm, poured it into a test tube container next to her, and then put it into an exquisite medicine box.

The medicine box was already filled with blood-red test tubes.

Yu Zi lay on the table, looking at her rolled-up, pale arms. Her lips were a little pale, and she felt her legs trembling so badly that she didn't even have the strength to get up.

Tamayo looked at the box full of her creations and nodded in satisfaction. She then turned to look at Tanjiro, who was in a daze.

"Tanjiro, may I collect some of Nezuko's blood?"

"Nezuko can recover her strength by sleeping and has not become more ferocious due to hunger. Her blood may play a remarkable role."

Tanjiro looked at the rows of bright red test tubes in the medicine box with a look of horror, and then at Yuko, who was still lying on the table, not yet recovered.

Will die!

Nezuko will die!

You will definitely die!!!

Tamayo said gently, "It's alright, Nezuko only needs a small vial of her blood."

Tanjiro, trembling as he held Nezuko, asked, "R-really?"

He felt that Miss Yuko was about to die.

Tamayo smiled and nodded: "Of course, Ikuko had more blood samples because they are very valuable for reference..."

boom!

Suddenly, a loud bang was heard, the wall cracked, and rubble flew everywhere, raising a cloud of dust.

"Ahem." Tanjiro stood in front of Nezuko, clearing away the dust in the air, and called out to those beside him, "Miss Ikuko! Miss Tamayo!"

A pale arm parted the dust, clutching a ball in its hand.

Tanjiro exclaimed in surprise, "Miss Ikuko!"

Yu Zi quickly pulled the white cloth off her neck with her other hand and turned around to ask, "Are you alright?"

"Yes, I'm fine." Tamayo almost instinctively assumed a defensive stance, and with Ikuko in front of her to shield her, she wasn't hurt at all.

Yuko lowered her eyelids slightly, looking at the restless, trembling ball in her hand.

The force... was a bit too much.

"Lord Tamayo!!!" Yushiro's voice came from afar as he rushed in through the door.

He breathed a sigh of relief after seeing that Tamayo was safe and sound.
