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

They were warmly received by Tanji and stayed at his house for several days.

After leaving Tanji's house, the two returned to the place where they were born.

The once prosperous and thriving country of Tsugumi became desolate and decayed in just a few years after Iwakatsu left.

I learned from other people in the city that after the ruler of the country, Jiguo Yansheng, abandoned his wife and children and left, Jiguo was left with only his weak matriarch and young children, and was soon swallowed up by others.

After repeated investigations, the brother and sister learned that in order to avoid disaster, Iwakatsu's descendants had changed their names to Tokito and moved to the deep mountains to make a living by logging.

The brother and sister secretly went to check on them and, after confirming that they were safe and sound, left with peace of mind.

The two used the money they had earned from slaying demons in recent years to buy a small house in the city and temporarily settled in their hometown.

After settling in, Yoriichi wrote a letter to the Flame Hashira of the Demon Slayer Corps, inquiring about his battle with Muzan and hoping for assistance.

Although Tamayo once said that Muzan probably wouldn't reappear before his death.

But Yoriichi was unwilling to give up. While taking care of his increasingly ill sister, he maintained contact with the Pillars of the Demon Slayer Corps and searched for Muzan Kibutsuji.

This stay lasted for two years.

That year, Yuko was twenty-five years old, and Yoriichi was twenty-six.

The old rule that people with age spots will not live past 25 has been broken.

Yuko was not surprised, just as Iwakatsu was jealous of Yoriichi, who was always the exception.

There may be differences in lifespan between naturally occurring and acquired facial markings.

When Yoriichi turned twenty-six and discovered that he had not died from the mark, he no longer openly went out to search for Muzan's whereabouts.

Instead, they hid, hoping that Muzan would misjudge the lifespan of the Marked Swordsman and reappear in this world.

Unfortunately, Muzan had no other skills, but he was well-versed in the principles of cunning and ruthlessness, and never revealed a trace of himself.

As time went on, Yuko's illness worsened, and she coughed up blood more and more frequently.

While Yoriichi was out searching for a doctor, Ikuko took out an envelope she had prepared for who knows how long. After placing it on the table, she picked up her Nichirin Blade and left home.

She didn't want to die in front of Yoriichi; it would be too humiliating.

When Yoriichi returned to the house with the doctor, all that was left for him was an envelope on the table.

……

As day turned to night, Yuko walked numbly along the road, not knowing how much time had passed.

"Goo~"

A subtle sound came from her stomach.

hungry.

But she didn't bring any food with her.

Yuko found a rock and sat down against it.

The afterglow of the setting sun shone on her face, carrying a faint warmth.

She didn't know if she would have another journey after she fell asleep.

Heaven has already given her a chance, allowing her to feel her mother's care and her brother's kindness.

Although she was still a little unwilling, there was nothing she could do.

As the last rays of the setting sun disappeared, Yuko slowly closed her eyes.

……

"Miss Yuko? Is that Miss Yuko?"

I don't know how much time had passed, but suddenly I heard a pleasant voice calling out to me.

Did my elder brother send someone to find me?

She had already gone so far.

Yuko's eyelashes trembled slightly as she slowly opened her eyes.

Before her stood a girl in a Demon Slayer Corps uniform; she seemed to have seen her somewhere before.

"you are?"

The girl knelt down and smiled gently, "Yu Zi, don't you remember me? Five years ago, you saved my life at a temple in the mountains."

Vague memories resurfaced in her mind, and Yuko's eyes cleared slightly.

"You are...Namiko?"

Before her stood the girl who had warmed Yuuko with her body heat during the snow mountain exorcism that day.

Seeing that Yuko remembered her, Namiko smiled happily: "Miss Yuko still remembers me."

"You... joined the Demon Slayer Corps?"

“Yes, ever since I was saved by Miss Yuko five years ago, I have always wanted to repay your kindness.” Namiko slowly knelt down in front of Yuko.

"I finally joined the Demon Slayer Corps three years ago, but unfortunately I learned of Ms. Yuko's departure as soon as I joined, and I was unable to see her."

"I didn't expect to meet you here. Have you heard about the evil spirits in the mountains?"

Ikuko was slightly stunned: "Evil ghost in the mountain?"

"Yes, it's on the mountain behind you, at the home of a samurai. His wife and children have been missing for several days now."

Have you received your mission?

"Ah."

Yuko's eyelids drooped slightly, and a clear world unfolded before her eyes, revealing the movement of Namiko's lungs.

In the past two years, she has become increasingly proficient in mastering the transparent world and can now use it reliably.

This breathing... is the breathing method of water breathing.

Water breathing is the most adaptable of the five breathing techniques.

However, Minako's understanding of Water Breathing is so rudimentary that even simple application is extremely superficial, let alone reaching a high level. At this level, even ordinary demons would probably find it difficult to deal with her.

Has the Demon Slayer Corps declined to this extent since they left?

"Goo~"

Just then, an awkward voice rang out.

"..."

Namiko quickly rummaged through her bag: "If Miss Yuko doesn't mind, I have some dry rations here."

“…Thank you.” Yuko did not refuse her kindness and chatted while eating.

Do you have any information about the evil spirits?

"Yes, intelligence suggests that the evil spirit possesses a peculiar blood demon technique and once disappeared with a samurai's wife in full view of everyone."

"Several people have been kidnapped in the past few days, and the samurai are helpless."

Yu Zi nodded slightly: "I'll go with you."

Blood Demon Arts can be seen as superpowers wielded by evil spirits.

These kinds of demons are often more powerful than ordinary evil spirits, and with Namiko's control over breathing techniques, she probably won't be able to handle them.

"Really? It's so great to have Ms. Yuko's help." Namiko breathed a sigh of relief and said wistfully, "This is actually my first time going out to hunt demons alone, and to be honest, I've been quite unsure of myself."

Yuko remained silent.

After eating something to fill her stomach, Yuko followed Namiko into the mountains.

The sun had already set, leaving only a few rays of its afterglow.

After walking uphill along the mountain path for ten minutes, a spacious mansion came into view.

I learned from Namiko that the mountain was the fiefdom of a certain samurai who had served under the shogun.

He was later granted this mansion as a reward when he retired from the front lines.

Namiko straightened her clothes: "Please wait a moment."

She knocked on the door.
