Demon Slayer: The Journey of Becoming Yoichi's Sister

Yae's father was placed in a remote place not far from the Demon Slayer Corps headquarters, and wisteria flowers that demons hate were planted inside and outside the house.

When I saw Yae again, the girl was wearing the Demon Slayer Corps uniform with a Nichirin sword on her waist.

"Miss Yuko!" From a distance, Yae saw the benefactor who saved her father from the two pillars running excitedly from a distance.

"Long time no see, Miss Yae." Yuko smiled and greeted her.

Yae's face was filled with emotion: "I have always wanted to say thank you to you."

After joining the Demon Slayer Corps, she truly understood what kind of pressure Yuko had to withstand to save her father from the two pillars.

Whenever she thought of this, Yae was deeply moved.

"Miss Yae comes to keep watch every night." Shinobu Kocho smiled and introduced: "Because she has to take care of her father, the lord specially sent someone to teach her breathing techniques and equipped her with a Nichirin sword."

"She is already a member of our Demon Slayer Corps."

Yuko nodded slightly. It was a high level of trust to let an evil ghost live in the Demon Slayer Corps' station. At least the safety issues cannot be ignored.

Yae didn't want to cause trouble to others.

Yae scratched her head a little embarrassedly: "Well, although my breathing techniques are still half-baked, it would be embarrassing for the Demon Slayer Corps to say it out."

Shinobu Kocho shook her head: "No, Miss Yae is very talented. It's amazing that she can practice breathing techniques to this level in two years."

Yuko subconsciously used the transparent field. In her observation, the way the girl breathes is... Breathing of the Wind?

Although she is a little immature and has not even reached the realm of full concentration breathing, there is definitely no problem for her to join the Demon Slayer Corps.

It seems that he is much worse than Tanjiro, but you have to know that Tanjiro's qualifications are already high in the Demon Slayer Corps, second only to geniuses like Tokito Muichiro.

But...

She thought it would be the Breath of Flame. After all, Yae is more outgoing, and his carefree appearance should be a good match for the Flame Pillar.

The two of them exchanged greetings for a while, and Yae's eyes noticed Yushiro and Tamayo who were carrying large and small bags beside him: "Who are these two?"

Ikuko: "It's a doctor."

Yae was stunned for a moment, then showed a happy expression, and said in panic: "That, that, I'll go open the door right away!"

Yae often communicated with Ikuko through letters, and had been waiting for the doctor Ikuko mentioned for two years.

Yae hurriedly came to the front of the house and opened the door, while Kocho Shinobu kindly helped everyone to clear the wisteria flowers outside the house.

"Please."

"Thank you." Tamayo's impression of this girl deepened a bit. She was a careful and gentle person.

Everyone entered the house surrounded by wisteria flowers. There was a faint smell of blood. In the middle of the room, a ghost was trapped with an iron chain.

Seeing everyone coming in, the iron chain made a rustling sound. The gray-haired evil ghost showed his bloody mouth to everyone, as if he wanted to tear everyone to pieces. Unfortunately, the iron chain locked him tightly and he couldn't break free.

"Dad!" Tears flashed in Yae's eyes. She wiped her tears and explained, "This is the case now. Recently, Dad has been awake for less and less time."

At the beginning, because of Yae's call, the old man could still stay awake from time to time, but as time went on, he was awake for less and less time.

Tamayo noticed the traces of blood in the utensils placed aside and understood it all at once.

"Blood alone cannot sustain a ghost's needs. Over time, he will inevitably lose his mind due to hunger."

Yae hurriedly asked, "What should we do?"

Tamayo said softly, "Don't worry, I'm here to solve this problem."

Seeing Tamayo's calm face, Yae's anxious heart calmed down a lot.

"Although there is no way to guarantee that he will become like a normal person, he can be transformed into me and Yushiro, who can maintain their sanity by only sucking a small amount of blood."

Kohiko Shinobu was slightly stunned, indeed...

The ghosts she usually encountered had a rancid smell on their bodies, but she didn't feel any rancid smell on this woman.

Maybe it was because the two had similar temperaments, which gave her a very close feeling.

Yae was a little excited: "Is it possible?"

Tamayo nodded slightly: "I think this old man has some special qualities, I think it can be successful."

It is not easy to transform a ghost into a ghost like them. For hundreds of years, the only successful cases are her and Yushiro who she turned into a ghost.

But the old man has a special physique, maybe it can be successful.

Tamayo looked at the house for a moment and asked: "It may not be possible to perform the operation here. Can Miss Butterfly find a bigger room?"

Butterfly immediately said: "Of course, the Butterfly House where I live is not far from here, we can go there."

"That's troublesome." After thanking, Tamayo looked at Yuko, "The task of controlling this old man is left to you, Yuko."

"No big deal." Yuko showed off her biceps.

Yuko came to the old man.

"Wuhou~" The old man's face was hideous, and he whimpered like a beast, as if he was waiting for an opportunity to hurt someone.

Yae volunteered: "I'll help."

"No need." Yuko rolled up her sleeves and chopped at the old man's neck with a knife.

The old man's hideous face froze, his dark eyes rolled up to reveal the whites of his eyes, and his struggling body softened all of a sudden.

Yae opened her eyes wide and couldn't speak. It was the first time she knew that ghosts could be knocked unconscious.

Yuko looked back at Tamayo: "Is that all?"

Tamayo: "..."

With Yuko's help, everyone easily controlled the crazy patient, which was even easier than giving anesthesia.

The group went to the Butterfly House.

"Miss Shinobu, you're back." When they arrived at the Butterfly House, a black-haired, blue-eyed girl with twin ponytails opened the door for them.

Shinobu Kocho knew that this was not the time to introduce, so she ordered: "Xiao Kui, please prepare an operating room for me."

"I understand." Kanzaki Aoi bowed to everyone and went to work quickly.

Shinobu Kocho guided everyone: "Please follow me."

Take the old man to the operating room, where the various medical devices inside are eye-opening.

In this era, such equipment alone is a huge expense.

The terrible super intuition of the Ubuyashiki family has accumulated a lot of wealth for them, which is really enviable. This may also be a little help from God for them to fight against Muzan.

Tamayo looked around and thanked, "The equipment is complete. Miss Butterfly is thoughtful."

"It should be..."

Seeing that Shinobu Kocho seemed to be hesitant to speak, Ikuko asked, "What's wrong, Shinobu?"

Shinobu Kocho opened her mouth and said, "I have something to ask Miss Tamayo."

Tamayo smiled and said, "Miss Butterfly, just speak frankly."

Shinobu Kocho pursed her lips and said, "Miss Tamayo, when you are operating, I hope you can allow me to watch from the side."
