Demon Slayer: The Journey of Becoming Yoichi's Sister

After receiving Tanji's warm hospitality, the two stayed at Tanji's house for several days.

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

The once prosperous country of succession had become withered just a few years after Iwakatsu left.

From other people in the city, they learned that after the succession country leader Iwakatsu abandoned his wife and children and left, only the weak mistress and young children were left in the country of succession, and it was soon swallowed up by others.

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

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

The two bought a small house in the city with the rewards they had earned from slaying demons in recent years, and temporarily lived in their hometown.

After settling down, Yoriichi wrote a letter to the Flame Pillar of the Demon Slayer Corps with the information about his battle with Muzan, hoping to get help.

Although Tamayo had said that Muzan would probably not appear again before he died.

But Yoriichi was still unwilling to give up. While taking care of his increasingly ill sister, he kept in touch with the pillars of the Demon Slayer Corps and searched for the figure of Muzan Kibutsuji.

This stay lasted for two years.

This year, Ikuko was 25 years old and Yoriichi was 26 years old.

The rule that people who activate the stripe transformation will not live beyond the age of 25 was broken.

Ikuko was not surprised. Just as Iwakatsu envied, Yoriichi was always an exception.

There may be differences in life span between natural stripes and acquired stripes.

When Yoriichi grew up to 26 years old and found that he did not die from the stripes, he no longer went out openly to search for Muzan's traces.

Instead, he hid, hoping that Muzan would misjudge the life span of the stripe swordsman and appear in this world again.

But Muzan had no other skills, but he was well versed in the truth of the way of hiding, and never showed any trace.

As time went by, Ikuko's illness became more and more serious, and the number of times she coughed up blood became more and more frequent.

While Yunichi was out looking for a doctor, Yuko took out the envelope that she had prepared for who knows how long. After placing it on the table, she took up the Nichirin sword and left home.

She didn't want to die in front of Yunichi, it would be too ugly.

When Yunichi returned to the house with the doctor, all he had left for him was the envelope on the table.

...

Day and night alternated, and Yuko walked on the road numbly, and she didn't know how long it had been.

"Gu~"

There was a subtle sound from her stomach.

She was hungry.

But she didn't bring any dry food.

Yuko found a rock and sat down against it.

The afterglow of the sunset hit her face, with a faint warmth.

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

God had given her a chance to let her feel the care of her mother and the kindness of her brother.

Although she was still a little unwilling, she had no choice.

As the last bit of light from the sunset disappeared, Yuko slowly closed her eyes.

…

"Miss Yuko? Is that Miss Yuko?"

I don't know how long it took, but suddenly a pleasant call came to my ears.

Did my brother ask someone to find me?

Even though she had already walked so far.

Yuko's eyelashes fluttered and she slowly opened her eyes.

What came into view was a girl in the uniform of the Demon Slayer Corps. She seemed to have seen her somewhere before.

"Who are you?"

The girl squatted down and smiled gently: "Yuko, don't you remember me? Five years ago, you saved my life in the temple in the mountains."

The vague memory revived in her brain, and Yuko's eyes became slightly clearer.

"You are... Namiko?"

The girl in front of her was the girl who used her body temperature to keep Yuko warm when she killed the demon in the snowy mountain that day.

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

"Have you... joined the Demon Slayer Corps?"

"Yes, after being saved by Miss Yuko five years ago, I have always wanted to repay your kindness." Namiko slowly knelt down in front of Yuko.

"Finally joined the Demon Slayer Corps three years ago, but unfortunately I learned about Miss Yuko's departure when I joined the team, so I didn't get to meet her."

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

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

"Yes, it's on the mountain behind you, in the home of a samurai, his wife and children have disappeared for several days without reason."

"Have you received the mission?"

"Yes."

Yuko's eyelids drooped slightly, and the transparent world unfolded in front of her, and the movement of Namiko's lungs was fully revealed in front of her.

In the past two years, she has become more and more proficient in the transparent world and can use it stably.

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

Water Breathing is the most adaptable breathing method among the five major breathing methods.

But Minako knows about Water Breathing.Not to mention the realm of the ordinary, even the simple application is extremely superficial. At this level, even ordinary evil spirits may find it difficult to deal with it.

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

"Gu~"

Just at this moment, an awkward voice sounded.

"..."

Namiko quickly turned over the bag: "Miss Yuko, if you don't mind, I still have some dry food here."

"...Thank you." Yuko did not refuse her kindness, and chatted while eating.

"Do you have any information about the evil spirit?"

"Yes, the information speculates that the evil spirit has mastered a strange blood demon technique and once disappeared with the samurai's wife in public."

"In the past few days, several people have been kidnapped, and the samurai can't do anything."

Yuko nodded slightly: "I'll go with you."

Blood demon technique can be regarded as a superpower mastered by evil spirits.

This kind of ghost is often stronger than ordinary evil ghosts. With Namiko's control of breathing, it may be difficult to deal with it.

"Really? It's great to have Miss Yuko's help." Namiko let out a long breath and said sadly, "This is actually my first time going out to hunt ghosts alone. To be honest, I have always been very unsure."

Yuko remained silent.

After filling her stomach, Yuko followed Namiko into the mountains.

The sun had already set, and only a little afterglow of the sunset was still shining.

After walking up the mountain path for ten minutes, a large mansion came into view.

From Namiko, I learned that the mountain was the fief of a samurai who had served under the general.

Later, when he retired from the front line, he was awarded this mansion.

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

She knocked on the door.
