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

As the homeless man fled in a panic, Yuko's eyes detected the swordsman's heart pounding with fear.

That frequency is almost matching the conditions for activating the markings.

His breathing frequency and lung movement are so poor that he can't even concentrate on breathing properly; he's practically an apprentice who hasn't mastered breathing techniques.

She's not even as good as Namiko.

The demons they could handle had only ever eaten one or two people at most, and they had never eaten a human at all.

The most important thing is mindset.

She simply walked over normally, without making any attempt to conceal herself.

They're so scared.

This means that the swordsman before them is unqualified as a demon hunter.

Because of Muzan and Kokushibo's targeting, the Demon Slayer Corps has had a really tough time these past few years.

Someone with this level of skill is capable of soloing ghosts.

This is not meant to be derogatory; it is simply stating a fact.

Even if he were lucky enough to investigate the Eternal Bliss Cult, he would ultimately only end up being devoured.

It could be said that Yuko's actions saved his life.

Yu Zi stripped off his coat, thought for a moment, and then wrote a few words on the ground with a knife.

'That's not a ghost you can handle. Go back.'

After doing all this, Yuko covered the swordsman with wild grass from the side to keep him from getting cold in the middle of the night.

She is so gentle.

Having taken the swordsman's uniform, Yuko returned to the clinic and happened to bump into Tamayo carrying her medicine chest, preparing to go out.

Yuko asked, "Are there any patients?"

"Hmm..." Tamayo responded first, then looked at the clothes in her hand and asked, "That's... the Demon Slayer Corps uniform, right?"

Have you made contact with the Demon Slayer Corps?

Yuko shook her head: "No, I just happened to run into a Demon Slayer Corps swordsman while investigating demons."

Tamayo's face paled: "You...?"

Yuko's eyes fell silent.

Tamayo's expression returned to normal, and she smiled slightly: "Just kidding."

"But Yuuko, did you steal his clothes because you plan to act as a member of the Demon Slayer Corps?"

Yuko asked, puzzled, "Why can't it be someone else lending it to me happily, or giving it to me as a gift?"

Tamayo was silent for a moment: "Do you even believe what you're saying?"

"..."

Yuko changed the subject and asked again, "Are you going out?"

Tamayo nodded slightly: "Yes, there is a critically ill patient."

As a ghost doctor, Tamayo only goes out to treat patients at night.

Yuko suggested, "Then I'll go with you."

Tamayo glanced at the clothes in her hands: "Won't this affect your plans?"

Yu Zi shook her head: "No, there was a small problem. I'll go over there tomorrow."

They're a family of three having a reunion there; she can't be that blind.

"That's good." Tamayo nodded with a smile.

"Give it to me." Yuko held out her hand.

"Then I'll have to trouble you, Yuko." Tamayo skillfully handed her the medicine box.

"Small things."

Yu Zi casually slung the medicine box over her shoulder and tossed the clothes in her hands onto the counter.

"Let's go."

This wasn't the first time Ikuko had accompanied Tamayo on an outing.

It wasn't just to protect her safety; mainly, she felt bad about eating and drinking for free.

When she was at home, she could still rely on her parents for financial support.

Once we're outside, we still need to help out in some way.

Even setting aside his role as a bodyguard, helping to carry the medicine box would be a good thing.

The moonlight was bright, and the weather was getting colder, so Yuko couldn't help but shiver.

Yuko followed Tamayo to a courtyard, and it was clear that the family was quite wealthy.

The two arrived at the front of the house, and Yuko heard their weak, panting breaths.

It looks like he is indeed critically ill.

Tamayo opened the door, and there lay a boy on the tatami mat in the room. He looked to be about ten years old and was very young.

However, due to the torment of illness, the boy's face was not good-looking, and he was even somewhat thin.

Although his gaunt face made him look somewhat different from the person she remembered, Yuko still recognized him.

Yushiro.

To be honest, with her current memory, she would have a hard time recalling what someone looks like based on their name unless she saw it with her own eyes.

Just like when you reminisce about your junior high school classmates twenty years later, it's hard to remember what they look like.

Yuko never expected that Yushiro would have already met Tamayo during this period.

The two entered the room, and Tamayo sat down next to him.

Yuko then removed her straw hat, loosened the white cloth, and revealed her delicate nose.

It suffocated her.

Tamayo touched Yushiro's forehead, and Yushiro groggily woke up.

What I saw made my whole body feel as if it had been struck by lightning.

He automatically ignored Ikuko behind Tamayo, his eyes only fixed on the gentle woman in front of him.

My heart started beating faster.

Yuko keenly noticed this.

Did this guy... fall in love with Tamayo at first sight?

"Medicine kit." Tamayo's ethereal voice rang out.

Yu Zi quickly placed the medicine box next to her.

"water."

Yu Zi quickly boiled another basin of water and brought it over.

Tamayo folded a handkerchief and placed it on Yushiro's forehead to relieve his symptoms, then began to examine his body.

Yuko didn't understand either, so she just stood there waiting for help.

After a while, Tamayo slowly put her things away.

She hesitated for a moment before saying to Yushiro, "Please wait a moment."

Tamayo stood up and nodded slightly to Ikuko.

Yu Zi understood and followed her out of the room.

Tamayo slowly spoke: "His illness, I'm afraid... cannot be cured."

Tamayo shouldn't have said that to her; she's neither a family member nor the patient herself.

Yuko saw through Tamayo's thoughts and calmly said, "Why not just turn him into a demon?"

Tamayo suddenly turned her head to look, her brows furrowed: "But... can something like this really be allowed?"

She was actually hesitant, which is why she said that to Yuko.

She saw Yushiro's desire to live, so she wanted to help him.

Yu Zi smiled and said, "Why don't we just ask him?"

Tamayo lowered her eyelids slightly, and before she could respond, Ikuko spoke again.

"Besides, I'll feel more at ease if he's with you."

Tamayo looked up in surprise: "Ikuko, you..."

Yuko smiled and explained, "There's something I want to do..."

She explained to Tamayo that she wanted to find information about the Upper Moons.

To investigate these evil spirits, she had to leave.

She was initially a little worried about Tamayo, but since Yushiro had appeared, it was best to leave her in his care.

After all, Yushiro is the one who stayed by Tamayo's side throughout the story.

As Tamayo listened to Ikuko's explanation, her expression became hesitant. She said with some unease, "The Upper Moon demons are the closest to Muzan, and they obtained a large amount of Muzan's blood..."

Yuko interrupted, "Don't worry, even if it's Kokushibo, I won't lose."

She wasn't killed by Yoriichi all these years.

She was confident that she would never lose to Kokushibo again.

If they were to run into each other, she would most likely be unable to continue hiding her identity, but she never intended to cause trouble for Kokushibo.

It's not time yet.

Tamayo saw the determination in her heart and closed her eyes slightly: "I understand."

Yu Zi smiled and said, "Well, let's go in and ask. I think he'll agree."

My heart is racing.
