Demon Slayer: The Journey of Becoming Yoichi's Sister

The Butterfly House is the logistical organization of the Demon Slayer Corps. It is a medical institution managed by the Butterfly sisters, and mainly provides treatment and rehabilitation for injured Demon Slayer Corps swordsmen.

Outside the Butterfly House, Yuko sat in the corridor and looked at the courtyard quietly.

There was a sound of footsteps on the side of the corridor.

"Sorry for the wait,"

With a quiet voice, Shinobu Kocho put down the tea set and sat beside Yuko.

"My sister is on a mission and can't come back." Shinobu Kocho explained, "I have to entertain Miss Yuko."

"It's okay." Hearing her sister mention her sister, Yuko subconsciously looked at her haori.

Shinobu Kocho noticed her sight and explained with a smile: "This is a gift from my sister when I became the top pillar."

"Very beautiful."

"Thank you." Shinobu Kocho chuckled, then remembered the tea she had placed, and handed it to Yuko, "Please, this flower tea tastes very good."

Flower tea?

Especially wisteria flowers.

Yuko took the teacup and couldn't help but look at it twice more.

Although she has overcome the sun, the toxin of wisteria flowers is still effective on her.

Of course, the effect is not great. Even if it penetrates into the body, it will be quickly decomposed. Unless the dosage is quite outrageous, it is difficult to affect her.

Fortunately, it is not. At the signal of Kocho Shinobu, Yuko picked up the teacup and tasted it lightly.

"Okay..." Before she could say her high EQ words, she heard Kocho Shinobu suddenly said.

"Miss Yuko... are you forcing yourself?"

"Hmm?" Yuko turned her head and looked at Kocho Shinobu's complicated expression.

"Miss Yuko... are you a ghost?"

Yuko was stunned for a moment, and her expression suddenly relaxed. She put down the tea in her hand and took a sip.

Smiled: "Hmm."

After getting a positive answer, Kocho Shinobu did not say anything, but turned her head and silently watched the setting sun.

It was just that the hand holding the cup exerted a little force, and it seemed that the inner unrest could be seen.

After a while, she said, "A ghost that can overcome sunlight... It's incredible."

"It's just a coincidence." The afterglow of the sunset was reflected in Yuko's eyes.

She had never thought of becoming a ghost, because within a certain range, Muzan has the ability to read the minds of evil ghosts.

If she hadn't been sure that she had gotten rid of Muzan's control, she would never have used the red spider lily to overcome the sunlight.

Shinobu Kocho didn't pay attention, but just looked at the sunset quietly: "What is the relationship between Miss Yuko and Muzan Kibutsuji?"

There was not much emotion in her voice, as quiet and peaceful as always.

Yuko didn't think much, and simply said, "Enemy."

Any person with a correct outlook on life could not tolerate what Muzan did.

All I saw along the way was misery.

"..."

Although Shinobu Kocho didn't look strange, Yuko could feel that she was much more relaxed.

Yuko would only keep the transparent field running when dealing with serious matters, and she wouldn't keep it open all the time.

The transparent field can only see through the human body, but not other objects. She is not interested in looking at a pile of skeletons all the time.

Shinobu Kocho's fingers holding the cup relaxed slightly, and her tense shoulders drooped slightly.

"My sister is a very gentle person, so gentle that even evil spirits will show mercy." She seemed to be talking to herself, and seemed to be talking to Yuko. "I hope humans can coexist peacefully with demons."

Yuko's eyelids drooped slightly, which is not a commendable concept.

No...

Even if it is Kanae Kocho, when she sympathizes with evil spirits, she will resolutely cut off the evil spirits' heads, just like Tanjiro.

Only she...

is really hesitant and timid.

Otherwise, she would not stop the two because of a trace of reason from Yae's father.

Shinobu Kocho said calmly: "I have never agreed with my sister's ideas, and I often argued with her because of this."

"Until two years ago, Miss Yuko saved her from the evil ghost."

"So..." Shinobu Kocho suddenly turned her head: "So I want to try to be like my sister, try to believe..."

Yuko smiled slightly: "Thank you."

...

After the two talked, Shinobu Kocho's heart was not so heavy.

She asked curiously: "Are there any ghosts like Miss Yuko in this world?"

"If you mean to overcome the sun, there should be none at present."

She silently added in her heart that Nezuko might be able to, but she didn't know much about it because she hadn't been exposed to the sun.

"If you mean to get rid of Muzan's control, I know that there are three besides me."

Shinobu Kocho opened her eyes slightly: "There are three more?"

"One is the doctor I mentioned before, named Tamayo, who is my good friend."

Shinobu Kocho couldn't help but say: "Ghost doctor?"

"Yeah."

Shinobu Kocho was very surprised, "ReallyUnbelievable."

If it was a ghost doctor, she would understand why he could surpass her in the field of evil ghost research.

"There is another one called Yushiro, who is Tamayo's companion."

"The last one is Nezuko, a cute sister. Maybe you can see her in two years."

When it comes to the unknown field, Kocho Shinobu is like a curious baby, eagerly asking: "Then how did you get rid of Muzan's control? ”

Yuko: “…”

The topic was so heavy that it was difficult to talk before, but now she is talking like a hundred thousand whys.

She patiently answered Shinobu Kocho's doubts, and the surprise on Shinobu Kocho's face did not fade until the evening.

After staying in the Butterfly House for two days, Yuko said goodbye to Shinobu Kocho and Ubuyashiki.

Before leaving, she handed over the information she had sorted out about the upper strings to Ubuyashiki.

It's called information, but in fact it's only the top three.

But Ubuyashiki was very happy. They had very little information about the Twelve Demon Moons, even the lower strings, let alone the upper strings.

The last record of killing the upper strings was more than a hundred years ago.

In addition, Yuko did not tell them about the information about the transparent field and the red sword for the time being.

This is not a skill that can be mastered immediately after explanation.

When leaving, Ubuyashiki sent A crow named Snowbird was brought to the team for communication.

Yae was temporarily arranged to stay with the Demon Slayer Corps, and she visited her father through the iron chain every day to try to awaken his mind.

Before going to Sagiri Mountain to visit Tanjiro, Ikuko went to Asakusa alone to try to find Tamayo.

But she searched for three days and three nights in Asakusa and did not see Tamayo.

Asakusa already has the appearance of a modern city, not a small town that can be seen at a glance. In addition, with Tamayo and Yushiro's blood demon arts covering it up, it is really difficult to find without Tanjiro's luck.

She used the crow to pass the message to Yae and told her not to give up hope.

As long as she didn't continue to eat people, she believed that she could effectively control it.

Ikuko, who failed to find Tamayo, had to leave Asakusa and head towards Sagiri Mountain.

It had been several months since Ikuko and Tanjiro and his group parted.
