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

A gentle voice came from behind him, and Tanji instinctively turned around to look, his tense expression slowly turning into surprise.

The pale golden sunlight shone on Yuko's profile, making her fair skin seem to glow. Her sunburned skin had somehow become smooth and flawless, and a faint white mist still lingered around her, giving her a hazy beauty under the refraction of light.

Tanji's surprised voice rang out, "Miss Yuko, you..."

Yu Zi turned her head and smiled, "Well, it seems like it was a success."

Zhu Mili rushed over, looked up at her, and said with sparkling eyes, "Sister Yuzi is so pretty."

Can you see the face?

Yu Zi looked down and had to stick her head out a little to see Zhu Mili's small head.

Yu Zi's breasts, even if not a D cup, are at least a C+ cup.

She gently patted Zhu Mili's head: "Really?"

Zhu Mili squinted his eyes contentedly: "When I grow up, I want to marry Sister Yu Zi."

Click~

Tanjiro's entire body turned black and white.

He said hurriedly, "No, Xiao Li, it will make things difficult for Sister Yu Zi."

Zhu Mili tilted his head and asked innocently, "Why?"

“Because…because…” Tanji racked his brains to explain to her.

Yuko and Zhu Miko, who came out from the inner room, watched the interaction between the father and daughter with smiles.

In the evening, after dinner.

Tanji tried to persuade him to stay: "Won't you stay a few more days?"

"Yes, my brother will worry if we get back late."

Zhu Mili waved goodbye to her, saying, "Goodbye, Yu Zi-neechan~ Come visit sometime~"

Yu Zi smiled and waved goodbye to everyone, saying, "Goodbye, Xiao Li."

Yuko told them not to worry about the spider lily and to treat it like any other wild vegetable.

……

At noon, Yoriichi wielded his Nichirin Blade in front of the courtyard, practicing his daily routine.

Even though Yoriichi was middle-aged, his face didn't show much maturity; he looked like he was in his early twenties even though he was over thirty.

Tuk-tuk-tuk~

Suddenly, there was a knock on the door.

Yoriichi wiped his sweat, sheathed his Nichirin Blade, and walked towards the door.

After the country's decline, the brother and sister returned to this place and lived there for a long time without attracting the attention of the people in the city, and they had no friends in the city.

Yoriichi was still somewhat puzzled as to who was knocking on the door.

He opened the door, and a flicker of emotion suddenly appeared in his calm eyes, which then rapidly expanded.

"I am back."

“Yuko, you…” Yoriichi looked at his sister in surprise, speechless.

Yuko stood in the sunlight and smiled, "I did it!"

Yoriichi's surprise softened, and a slight smile appeared on his lips: "It's good that you're back."

Yu Zi smiled and said, "Yes, I'm back."

……

After overcoming the sunlight, even Yoriichi wielding the Nichirin Blade could not pose a threat of death to her.

Even if her head is severed by the crimson blade, Yuko can recover completely in an instant.

Ultimately, even the Crimson Blade only stimulates the energy of the sun within the Nichirin Blade.

Having overcome the effects of sunlight, Yuko is no longer afraid of its derivatives.

Neither the Nichirin Blade nor the Crimson Blade, nor the regeneration suppression of the Sun Breathing technique, had any effect on her.

Before her at her complete form, the Nichirin Blade was nothing more than an ordinary samurai sword.

But that doesn't mean she's invincible.

Although she was no longer afraid of sunlight, she was still no match for Yoriichi in combat.

Although Yoriichi was unable to launch an effective attack against her, Ikuko was equally unable to defeat Yoriichi.

It's like a noob with an invincible cheat code still can't touch a pro player.

Furthermore, Yuko discovers that she is not truly invincible.

Although she overcame the sun, regeneration still consumes physical strength.

In other words, if Yoriichi keeps attacking her, it is still possible for him to wear her down to death.

Ignoring the special effects of the Nichirin Blade, Yoriichi taught her at his peak.

Thirty is the golden age for men, when their physical abilities reach their peak.

If he were to encounter Muzan at this time, the latter would have no chance to escape; he would instantly shred Muzan into 1,800 pieces of flesh.

After Yuuko gradually adapted, Yoriichi's intensity was also maximized.

He chopped Yuko so badly she almost questioned her existence.

The main thing is that she can definitely feel herself getting stronger.

But no matter how strong she gets, Yoriichi can always defeat her instantly when he gets serious.

No matter how wide the range of her sword strikes was, Yoriichi could always find an opportunity to break through.

As a demon, she did not possess the formidable power of Muzan.

As a human, she didn't have Yoriichi's talent.

She felt that if Muzan had her cells inside him, he would be under constant stress.

Every day, you can see the scene of Yoriichi mercilessly beheading someone, and it can be played for 365 days without repeating.

Life is hard for ghosts, Yuko sighed.

……

However, this joyful time did not last long.

One year, two years, five years...

Yuko could clearly feel that the people around her were getting older.

"Why doesn't Sister Yuzi ever grow old?" When Yuzi heard Zhu Mili ask her father this question outside the door, she knew it was time for her to leave.

Tanji explained stiffly, "Maybe it's because Yuko-neechan takes good care of herself."

Immortality was the dream of every emperor.

But for a sensitive person, the suffering brought about by immortality is absolutely unbearable.

It's a very painful feeling to be the only one who is still young while everyone around you is slowly getting old and moving towards death.

……

Time flies, and more than 20 years have passed in the blink of an eye.

Since that day, Yuko has never been to Tanjiro's house again.

Yoriichi is already over fifty years old.

Even Yoriichi has grown old; strands of white hair have appeared on his head, and his physical strength is gradually weakening.

Yuko has long been independent and is often away from home.

She couldn't bear to watch her loved ones grow old.

Yuko began to feel afraid of going home.

Birth, aging, illness, and death are the natural course of life, but she can't die.

Does she really have to wait hundreds of years until Tanjiro and the others defeat Muzan together?

Actually, it doesn't really matter whether she's there or not, right?

As people reach middle age, worries begin to arise in their hearts, and Yuko occasionally has such thoughts as well.

But she could no longer die.

Neither the Nichirin Blade nor the sun could destroy her.

A solitary moon hangs high in the sky, illuminating the lonely figure on the ground.

Yuko walked slower and slower, and what should have been a journey of a few days took her half a month to complete.

It was clearly her who wanted to go home and visit.

The more she understood this, the less she could take the plunge.

The brightly lit city was already close at hand, but Yuko stood frozen in place, unable to move her feet.

This cannot be described as a feeling of trepidation upon returning home.

She was scared.

She was afraid to see Yoriichi's face, which looked even older.

She has been away from home for more than three years.

Perhaps her decision was wrong; she shouldn't have tried to overcome the sunlight.

In this way, even if we can't grow old with our loved ones, at least we can die with them.

She has never been a strong person.
