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

"Ugh."

Life is hard for ghosts, Yuko sighed.

She removed the straw hat and veil that she used to cover her face. Although she probably didn't look strange, she couldn't see her own face, and it wouldn't be good if something went wrong.

There happened to be a bronze mirror in the room. She picked it up from the table and started scrubbing her face.

Everything was the same as before, as if I had just gotten a manicure.

Just as Yuko was thinking this, she suddenly noticed that her eyes seemed a little strange.

She pressed herself against the bronze mirror and pulled at her eyelids. In the mirror, she saw two pupils appear in her eyes.

Now that's good, I won't dare to laugh at Yan Sheng for being a jealous person anymore.

Two pupils appeared in one eye, one large and one small. The smaller one was almost stuck to the larger one, looking like some kind of adhesive distortion, making Yu Zi's wine-red eyes look very strange.

Double pupils?

The last one to be this awesome was a certain powerful overlord.

Does she also possess an aura of dominance?

Despite her distress, Yu Zi carefully examined the area and found that apart from the unusual change in her pupils, there were no other changes.

Yes, and there are two slightly protruding little tiger teeth.

Yu Zi grinned and focused her attention on the top of her head in front of the bronze mirror.

The next moment, two hideous demon horns emerged from it.

At first glance, they don't look like demon horns; they look more like dragon horns.

These two corners are at least 20 centimeters long, which means that if she stood up now, including the corners, she would be as tall as Iwakatsu.

Secondary development is considered to be true.

Yuko fully transformed into a demon, and her striking wine-red hair instantly turned white from the roots, while her fingernails also grew longer.

From a distance, it doesn't look like a strange and ugly demon, but rather more like an unknown deity.

The only thing that somewhat detracts from the aesthetics is probably the few grotesque blue veins under the skin when fully transformed into a demon.

Wow~

He's so cool!

Yuko's eyes lit up.

He looks so handsome!

After admiring her own beauty, Yuko reverted to her human form.

Only the double pupils in her eyes, perhaps because she is too weak now, have not been able to completely erase the characteristics of a demon.

Fortunately, it's not serious; wearing a straw hat to cover it up a bit will do.

Yuko pondered her next steps in her room.

Yes, I should at least let Yoriichi know I'm safe.

But she could only go home at night, otherwise Yoriichi might find her before she even got close to her house.

It wouldn't be good if Yoriichi treated it like a mob and killed it.

At least give him a heads-up.

With that thought in mind, Yuko called over a shop assistant.

"Could you please find me some paper and pen? I want to let my family know I'm safe."

Looking at the hair accessory in Yuko's hand, the shop assistant really couldn't think of a reason to refuse.

After writing the letter.

"Please deliver this letter to me again..."

"This is the reward."

Taking the jewelry from Yu Zi, the shop assistant suppressed her inner elation, patted her chest, and assured her, "Don't worry, miss, even if it costs me my life, I will definitely deliver the envelope to your family!"

Ikuko: "..."

She suddenly felt uneasy. What was wrong?

……

Yuko stayed here while the clerk delivered the mail.

It wasn't until several days later, when the shop assistant described Yoriichi's appearance in detail, that Yuko was convinced that he had been delivered.

As night fell, Yuko checked out of the room and walked down the street, starving.

She was so hungry she wanted to eat people.

In Yu Zi's eyes, the lights that lit up in every household were like the lights on a barbecue stall on the roadside late at night.

It makes you want to go closer.

She looked away, trying her best not to think about those things, and hurried on her way under the cover of night.

After becoming a demon, the injuries to his lungs healed, and his physical condition was greatly improved.

I used Changzhong's breathing techniques throughout the entire journey.

This was the first time she had used Snow Breathing so smoothly since mastering it.

……

In the pitch-black room, Yoriichi sat on the floor, with his Nichirin Blade and a broken white Nichirin Blade beside him.

He hadn't had a good night's sleep for several days.

Because of Yuko's letter.

[Dear Elder Brother]

I am Yu Zi, and I am truly sorry for leaving without saying goodbye.

But please listen carefully, brother. After leaving home, I stumbled upon a cave in the mountains... After becoming a demon, I discovered that I had broken free from Muzan's control and had not lost my mind, seemingly like Tamayo... I will return home sometime in the future.

This letter and the news about the Demon Slayer Corps were delivered to Yoriichi almost one after the other.

The Demon Slayer Corps told him that they had found signs of Ikuko fighting demons in a mountain, but they did not see Ikuko. They only found a broken Nichirin Blade at the spot.

The outcome is self-evident.

For an ordinary person, Yu Zi's letter would be almost like a ghost returning from the seventh day after a death.

Creepy.

Yuan glanced at Yu Zi's broken sword out of the corner of his eye, then sat there with a gloomy expression.

He vowed that if Yuko's letter was the work of Muzan, he would dig three feet into the ground to find Muzan.

They deceived him using Yuko's name and blasphemed a dead person...

Yoriichi looked up abruptly, his eyes fixed on the door.

……

Yuko had already entered the city, and he and Yoriichi lived not far from each other.

I don't know if Yoriichi was asleep at this time.

But given Yoriichi's senses, she probably already knew him before she even got close.

With that thought in mind, Yuko cautiously approached the house, praying that Yoriichi wouldn't mistake her for a lowly soldier and kill her.

She doesn't think she's ready to meet Yoriichi right now.

The one who was full of confidence and went head-to-head with Yoriichi has already retreated into his shell and won't come out anymore.

As she approached the house, Yuko's powerful senses as a ghost allowed her to instantly determine that a figure was sitting inside.

In the middle of the night...aren't you sleeping?

crunch~

Yuko furtively opened the door, and moonlight streamed in, illuminating Yoriichi's lower body as he sat.

The moment I saw Yoriichi, something seemed to flutter in my heart.

In a daze, a blurry figure wielding a crimson blade rushed towards her.

Those were the mutilated cells that remained in her body.

Yoriichi's eyelids twitched, and a clear world unfolded before him. The person in front of him was undoubtedly Yuuko.

But Yuko's murky aura reminded him that the person in front of him was indeed a demon.

But unlike other evil spirits, it did not have the foul smell of someone who had eaten people.

"Um, brother... why aren't you asleep so late?"

Yuko's somewhat embarrassed voice came through, and Yoriichi's cold expression vanished instantly.

Yoriichi, his expression somewhat moved, began, "Ikuko..."

Yuko closed the door and slowly sat down in front of Yoriichi.

Seeing Yoriichi's worried expression, he smiled gently and said, "I'm sorry, brother, I'm late."

Yoriichi paused for a moment, then smiled gently in return.

"Welcome back, Yuko."

That night, the brother and sister talked a lot.

Yoriichi, who once let Tamayo go, did not always intend to exterminate demons, let alone his own family.

But he felt only pity for what Yan Sheng had done.

Not only did he himself fall into depravity and become a ghost, but he also...
