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

After seeing the hawk away, Yuko went back inside.

Zhu Shi waved to her: "Yu Zi, come with me."

"what happened?"

Yuko obediently followed Tamayo, and the two went to the basement.

The room was filled with all sorts of professional medical equipment.

Tamayo gestured for her to sit down to the side, and Ikuko, not knowing what she was going to do, sat down obediently.

Tamayo took out a syringe and pricked her hand with a needle.

Yu Zi stared at her wide-eyed. Was she being treated like a mobile blood bank, or was she being asked to pay back the rent for the room and board she had paid back years ago?!

She clearly paid for it with her physical strength!

Tamayo ignored her resentment, dripped the blood onto a vessel, and placed it in front of a microscope for observation.

A moment later, Tamayo raised her head.

"really……"

Yuko looked at him in confusion: "Hmm?"

Tamayo raised her eyes slightly to meet her gaze: "Yuko, how many years has it been since you drank human blood?"

Yu Zi hesitated and said, "After we break up."

"You should know that for a ghost to achieve immortality, it actually needs to meet a certain condition."

"That is eating, which is obtaining energy."

"Having not eaten for two hundred years, the cells in your body are aging rapidly, and the rate of cell division has become extremely slow."

"Perhaps you haven't realized it yet, but your regenerative ability is probably not as good as before." Tamayo knew very well that with Ikuko's strength, there weren't many beings who could force her to use her regenerative ability.

“No, look.” Yu Zi bent her finger, her nail scratching a line in her palm.

The wound healed quickly, even before blood began to seep out.

"Just like before."

Tamayo glanced at it and said indifferently, "For a normal person, such a minor injury would be almost fully healed by the time they get to the hospital."

"...Well, it can't be that bad, can it?"

Tamayo couldn't help but ask, "Don't you feel anything yourself?"

Yuko nodded seriously: "Yes, sometimes I feel very hungry and want to eat something."

"Then why don't you eat?"

Even if they don't want to eat people, they'd be happy to just drink some blood.

Yuko shared her feelings: "Because sometimes the feeling of hunger just disappears if you just endure it."

Tamayo's eyes twitched: "That's your body's cells trying to save themselves, which is why your body's cells are getting older and older."

"If this continues, your hair will start to turn white in less than ten years, and you will officially enter the old age stage of human life."

Yuko was speechless for a moment, then quickly retorted, thinking of Nezuko, "Look, Nezuko has never drunk blood either."

“But Nezuko has been asleep, and something is happening inside her. She might become the second demon, after you, to overcome sunlight.” Tamayo said, opening the refrigerator behind her and taking out several bags of blood.

Yuko raised her hand in refusal: "No, I won't..."

Before she could finish speaking, Tamayo said, "I know you don't want to, but in your current state, how are you going to fight Muzan if you encounter him?"

Yuko opened her mouth, but couldn't say a word.

She has indeed become weaker... because she hasn't eaten for so long...

Because she had never encountered a formidable opponent, she had never thought about this issue.

Without a word, Tamayo shoved the blood pack into her hand: "You can't win a battle on an empty stomach."

"Take it from the refrigerator after you finish drinking. I need to go help Yushiro pack his things."

Tamayo closed the door and left, while Ikuko stared at the blood packet in her hand, her mouth watering.

She swallowed.

I think it should be fine to drink just a little bit.

……

the other side.

Infinite city.

The boy with short white hair calmly looked around, his pupils reflecting the character "Xia Wu".

"Hey, what's going on? Where am I? Why are all the Lower Moon demons here?" On Lower Moon Land, Kameue ​​looked at the demons with sweat dripping from his forehead.

'Is it that woman's Blood Demon Art?' The Lower Moon demons looked at the female demon sitting high up, holding a pipa, with apprehension.

when!

With a clear, melodious sound like a pipa, the space shifted, and the ghosts appeared on a platform.

Upon seeing the figure standing in front of the platform, all the ghosts knelt down in unison.

"Master Wuhan!"

Muzan Kibutsuji was in a bad mood.

Although he was mentally prepared, Muzan still couldn't help but feel angry when those two good-for-nothings died at the hands of those two demon hunters.

It wasn't anger at them for not completing the mission, but rather...

'That monster's techniques... have actually been passed down...'

Dressed in a black suit and appearing as a young man, Muzan Kibutsuji stared at the kneeling Lower Rank demons with a livid expression.

Muzan suppressed the anger in his eyes and said in a low voice, "Kill the demon slayer wearing the Hanafuda earring. Whoever brings me his head, I will grant him the power to reach the Upper Moon."

Those two good-for-nothings didn't die in vain; at least they showed him something.

Surprisingly, the woman who initially made him feel threatened actually made him feel much more at ease.

Although he possesses some talent, even comparable to Hantengu, in Muzan's eyes he is nothing more than a slightly larger ant.

In comparison, the demon hunter wearing flower earrings... that move... he remembered it clearly even after hundreds of years.

Without a doubt, it was that monster's swordsmanship.

It actually survived.

Although he is still a bit naive and the type that Muzan would never normally pay attention to, he cannot tolerate it and cannot sleep at night once he gets involved with that monster.

We must... kill that demon hunter.

The demons' impression of Muzan was first and foremost fear, and only then anything else.

But upon hearing the promise Muzan made, the demons, who had initially been somewhat fearful, excitedly raised their heads: "Yes, sir! We will bring the demon slayer's head to you, my lord!"

For a Lower Moon demon to become an Upper Moon demon, unless Muzan values ​​him highly, it is almost impossible to advance through cannibalism and seat battles.

Among the ghosts, only the white-haired boy with the mark of a soldier etched in his eyes showed little interest.

Compared to power, family is definitely more important. However, I should still pay more attention to Lord Muzan's orders.

Hearing Lei's heartfelt words, Muzan was somewhat dissatisfied, but he didn't say anything more.

Both being human, Muzan was physically weak and prone to early death, but his kindness towards Rui was unparalleled by any other demon.

……

Yuko was unaware of the meeting being held on the Ghost's side; she was currently facing an awkward situation.

"Lord Tamayo! Something terrible has happened! A thief has broken into the basement!" Yushiro exclaimed breathlessly as he flung open the door.

"Pfft~" Yuko, who was leisurely drinking her blood-red beverage, almost vomited all over Tamayo's face.

Yuko lowered her head somewhat guiltily.

It's over.

She hadn't eaten in so long that she couldn't stop drinking after taking a sip.

By the time she realized what was happening, the blood bank had already been emptied.

This is different from a hungry person who stops eating when they are full. A ghost's body will convert this blood food into energy, so drinking blood is impossible to achieve satiety.

Tamayo paused for a moment, then laughed and said, "It's alright, the blood was going to expire anyway."

"How could that be! I just..."

Tamayo suddenly interrupted: "Yushiro."

Yushiro paused in his speech.

"Have your things been packed?"

"……Yes."

Tamayo glanced at the bright moon outside the window: "Then let's go."
