Demon Slayer: The Journey of Becoming Yoichi's Sister

After sending the crow away, Yuko returned to the house.

Tamayo waved at her: "Yuko, follow me."

"What's wrong?"

Yuko followed Tamayo honestly, and the two came to the basement.

The room was filled with various professional medical equipment.

Tamayo gestured for her to sit aside, and Yuko didn't know what she was going to do, so she sat down obediently.

Tamayo took out a syringe and gave her a shot in the hand.

Yuko looked at her with wide eyes. Was she treating her as a mobile blood bank or did she want her to pay back the rent for the food and accommodation she had provided? !

She had paid it back with her physical strength!

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

After a while, Tamayo raised her head.

"Sure enough..."

Yuko looked at him in confusion: "Hmm?"

Tamayo raised her eyes slightly and looked at her: "Yuko, how many years have you not drunk human blood?"

Yuko hesitated and said: "After we separated."

"You should know that ghosts need to meet a condition to live forever."

"That is eating, that is, obtaining energy."

"After not eating for two hundred years, the cells in your body are aging rapidly, and the speed of division has become quite slow."

"Perhaps you haven't noticed that your regeneration ability must be much worse than before." Tamayo knew very well that with Yuko's strength, there were not many people who could force her to use her regeneration ability.

"No, look." Yuko bent her fingers and cut a hole in her palm with her nails.

The hole just bleeds and heals quickly.

"Just like before."

Tamayo glanced at him and said calmly: "This kind of minor injury, a normal person would be almost healed if sent to the hospital."

"... Well, not really."

Tamayo couldn't help asking: "Don't you feel anything yourself?"

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

"Then why don't you eat?"

Even if you don't want to eat people, just sucking some blood is fine.

Yuko shared her feelings: "Because sometimes if you endure hunger for a while, it will disappear by itself."

Tamayo's eyes twitched: "That's the cells in your body saving themselves, so the cells in your body will become more and more old."

"If this continues, within ten years, your hair will start to turn white, and you will officially enter the old age stage of humans."

Yuko was choked for a moment, thinking of Nezuko and quickly defended: "Look, didn't Nezuko drink blood?"

"But Nezuko has been sleeping, and her body is changing. She may become the second ghost to overcome the sun after you." Tamayo said as she opened the refrigerator behind her and took out a few bags of blood.

Yuko raised her hand to refuse: "No, I don't..."

Before she finished speaking, she heard Tamayo say: "I know you don't want to, but in your current state, if you meet Muzan, how are you going to fight him?"

Yuko opened her mouth and couldn't speak.

She did become weaker... because she hadn't eaten for too long...

Because she had never encountered a strong enemy, she had never thought about this problem.

Tamayo stuffed the blood bag into her hand without saying anything: "You can't win a battle on an empty stomach."

"Take it from the refrigerator after you finish drinking it. I have to go help Yushiro pack up."

Tamayo closed the door and left. Yuko drooled as she looked at the blood bag in her hand.

She swallowed.

Just... just drink a little bit, it should be fine.

...

On the other side.

Infinite Castle.

The boy with short white hair, with the image of the lower-ranked in his pupils, looked around calmly.

'Hey, what's going on? Where is this? Why are all the lower-ranked here?' In the land of the lower-ranked, Kama-nue looked at the demons with sweat on his forehead.

'Is it the blood demon art of that woman?' The lower-ranked looked at the female demon sitting on a high place with a pipa in her hand.

Ding!

With a clear sound of the pipa, the space turned around and the ghosts appeared on a platform.

When they saw the figure standing in front of the platform, the ghosts knelt down in unison.

"Lord Muzan!"

Muzan Muzan was in a bad mood.

Although he had been mentally prepared, he couldn't help but feel angry when the two trash died in the hands of the two ghost hunters.

It was not because they didn't complete the task, but...

'The moves of that monster... turned out to be passed down...'

Wearing a black suit and appearing as a young man, Muzan Muzan looked at the kneeling lower-rank ghosts with a sullen face.

Muzan restrained the anger in his eyes and said in a low voice: "Kill the ghost hunter wearing the flower card earrings for me. Whoever can bring his head, I will give him the power to reach the upper rank."

The two trash didn't die in vain, at least he saw something.Unexpectedly, the woman who had given him a sense of crisis at the beginning actually made him feel more at ease.

Although she had some talent, even enough to be compared with Hantengu, she was nothing more than a larger ant in Muzan's eyes.

In comparison, the ghost hunter wearing flower-shaped earrings... that kind of moves... even if hundreds of years had passed, he could still remember them clearly.

There was no doubt that it was the swordsmanship of that monster.

It was actually passed down.

Although it was still a little immature now, and was the type that Muzan would never pay attention to on weekdays, as long as she had anything to do with that monster, he would not tolerate it and could not sleep at night.

Must... kill that ghost hunter.

The ghosts' impression of Muzan was first fear, and then other things.

But after hearing the big cake given by Muzan, the ghosts who were originally a little afraid raised their heads excitedly: "Yes! I will definitely bring the head of that ghost hunter to you!"

It is almost impossible for a lower-rank ghost to become an upper-rank ghost unless Muzan values ​​him. It is almost impossible for him to be promoted by eating people and fighting for seats.

Among all the ghosts, only the white-haired boy with the image of a lower class in his eyes was not interested.

Compared to strength, family is more important, but Muzan-sama's orders should be paid more attention.

Although Muzan was a little dissatisfied when he heard Rui's voice, he did not say much.

As a human being with a weak constitution and a premature death, Muzan's kindness to Rui is unmatched by other ghosts.

…

Yuko didn't know about the meeting of the ghosts. She was facing an embarrassing situation now.

"Master Tamayo! It's bad! A thief broke into the basement!" Yushiro opened the door and said breathlessly.

"Puff~" Yuko, who was drinking the bloody drink leisurely, almost vomited in Tamayo's face opposite her.

Yuko lowered her head with a guilty conscience.

It's over.

She really hadn't eaten for too long, and after taking a sip, she couldn't stop.

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

This is different from a hungry person who stops eating when full. The body of a ghost will convert the blood into energy. It is impossible to drink blood to get full.

Tamayo was stunned for a moment, then smiled and said, "It doesn't matter. The blood was about to expire."

"How is that possible! I just..."

Tamayo suddenly interrupted, "Yushiro."

Yushiro paused.

"Have you packed your things?"

"...Yes."

Tamayo looked at the bright moon outside the window and said, "Let's go."
