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

This news was like a magnitude 10 earthquake to Yu Zi.

Yoriichi got married?

You've been hiding it well, kid!

Five years had passed since they last met...

Yuko's impending rant stuck in her throat.

Yoriichi was already married, so there was no reason for him not to tell his younger sister.

unless……

Yuko couldn't bring herself to ask the question; she simply followed Yoriichi with a heavy heart.

One night, they arrived at a mountain.

Yuko used the moonlight to see the road ahead: "Brother, there seems to be a house ahead."

As soon as she finished speaking, Yoriichi gripped the Nichirin Blade at his waist and sped toward the house at an incredible speed.

Evil ghost!

Yuko reacted just as well, gripping the knife handle tightly and following closely behind.

When a member of the Demon Slayer Corps leaves the team, their Nichirin Blade is often retrieved.

However, out of consideration for Yoriichi and Ikuko's contributions to the Demon Slayer Corps, the Lord allowed them to keep their Nichirin Blades.

Yoriichi's perception far surpassed hers; it wasn't until she was about twenty meters away from the house that she sensed the demon's presence.

"Brother, are you alright?"

By the time she burst into the house, the demon's body was already beginning to crumble.

As expected of Yoriichi, he is as powerful as ever.

The person who had been rescued breathed a sigh of relief.

"We're saved!"

Yu Zi looked in the direction of the sound, her eyes widening slightly, a look of surprise appearing on her face.

Tan...Tanjiro?

"My name is Tanji, and I am extremely grateful to both of you for saving my life."

A man who looked similar to Tanjiro, the protagonist of Demon Slayer, knelt on the ground and bent down to introduce himself.

It's not unusual to receive such a grand gesture for someone who saved your life, but Yuko doesn't like it.

She stepped forward and helped him up, saying, "No need for formalities, slaying evil spirits is our duty..."

Yuko paused, then said, "They've already left the Demon Slayer Corps."

Tanji didn't think much of it, and just looked at the two of them gratefully: "It's getting late now. If you two don't mind, you can stay at my humble abode for the night."

Yuko turned to look at Yoriichi. They had been traveling day and night for several days, but had not yet reached Yoriichi's wife's residence.

Yoriichi suddenly asked, "Is anyone else in the inner room?"

If there were just other people around, he wouldn't care this much...

Tanji's eyes turned into beady eyes. He froze for a moment, then panicked and ran into the inner room, muttering in alarm.

"Oh no! Zhu Mizi!"

The two followed closely behind, and lying on the bed in the inner room was a woman with a large pregnant belly.

The woman was struggling on the bed with a pained expression.

"Zhu Miko!" Tanji called out his wife's name in a panic.

"Excuse me." Yu Zi stepped forward and pulled him aside, giving him a quick check.

"She's about to give birth, we need to find a midwife quickly." Yu Zi turned to the two of them and said, "Brother, please take care of them, I'm going to the town at the foot of the mountain now..."

Before Yuko could finish speaking, Yoriichi turned and left.

Leave only one sentence.

"Yuko, take good care of them, I'll be right back."

Yoriichi's promise to return immediately truly came true.

It didn't take much time before Yoriichi returned carrying the midwife on his back.

Upon seeing Tanjiro's wife, Sumiko, safely give birth to a baby girl, Yoriichi's usually calm expression wavered slightly, and a faint smile appeared on his lips.

But Yuko read sadness on his face.

……

Tanji was taking care of his wife in the inner room. The two sat on the door sill, watching the sunrise. Yoriichi seemed to understand his sister's confusion and explained softly, "This is... the place where Shi and I used to live."

really……

Yuko pursed her lips.

Zhu Miko was resting in her room after giving birth, while Tanji invited his two benefactors to stay for dinner.

"I am so sorry, there is nothing good to eat at home, so please try the wild vegetables that Zhu Mizi picked yesterday."

Yu Zi smiled slightly: "It's good enough to fill our stomachs."

What good food could there be in this era? Yu Zi has never been picky about food.

Soon, Tanji had prepared the food.

Several plates of wild vegetables were served on the table.

The cooked wild vegetables were mostly wilted and unrecognizable, but since Tanji was willing to give them to eat, they must be non-poisonous.

After breakfast, Yoriichi took Ikuko to the back of the house.

It was a grave mound made of a few rubble stones.

It is the grave of poetry.

Yoriichi came to his wife's grave and told her the story of how he joined the Demon Slayer Corps.

Yuko knelt to one side, listening quietly.

One must not be disrespectful when paying respects to one's relatives.

Yoriichi's story is long. He tells their story slowly in a careful and gentle voice, talking about his long-awaited reunion with his brother and sister, and the days when the three of them practiced breathing techniques together.

The sun was shining brightly; it was August, and the weather was incredibly hot.

Yoriichi realized this and turned to his sister, saying, "Yuko, if you're not feeling well, you should go back first."

Yoriichi's eyes could clearly see Ikuko's physical condition.

He knew all too well that his sister didn't have much time left.

Yu Zi shook her head: "It's nothing."

In fact, she quite likes summer.

Yuko has a rather unique constitution; she is naturally inclined to prefer cold and is not afraid of heat, which may be the reason why she successfully mastered the Snow Breathing technique.

Yoriichi nodded slightly, understanding his sister's thoughtfulness, and continued to talk to his wife.

Just as Yuko was about to stretch her legs, which were a little numb from kneeling for too long, a flash of blue suddenly caught her eye from the corner of her eye.

Yuko glanced sideways and saw several blooming blue flowers swaying in the wind beside the poem's grave.

Is this... a spider lily?

But why is it blue?

And weren't these flowers there just now? How come she didn't notice them?

Blue spider lily...

Suddenly, some memories of her past life flashed through Yuko's mind.

She felt like she'd seen that word somewhere before...

It's in...

Yu Zi's eyes widened slightly; she remembered!

She had seen the blue spider lily that Muzan had been searching for—the one that could overcome the sunlight—in the comments section!

Then a brilliant idea struck her.

No wonder Nezuko was able to overcome the sunlight; it's because this plant grows near their house!

Has no ghost passed through here in the last few hundred years?

This went unnoticed by the scumbag boss.

Sudden.

???

What the hell?

Ikuko was stunned.

The blue spider lilies that were blooming brightly just a moment ago withered and died in a few breaths, leaving behind branches that looked like casuarina trees.

She instinctively reached out to touch it, and it had truly withered.

Right in front of her.

For no reason.

What principle?

No wonder the scoundrel couldn't be found; this flower is quite magical.

"Yuko, what's wrong?" After paying respects to his wife, Yoriichi turned around and saw his younger sister staring blankly at a few casuarina trees.

"No, it's nothing."

"Then let's go."

"Ah."

Yuko hesitated for a moment, but still did not break it.

She wasn't sure if the flower only existed here; if it did, it would certainly shatter the boss's dream of sunbathing.

But if not...

Then Nezuko is finished.

She was a talentless person and in the end, she couldn't change anything.

Whether it's ending Muzan's reign in this era or saving Kokushibo.

She accomplished nothing.

But she knew that Tanjiro and Nezuko could definitely defeat Muzan.

As an outsider, I can no longer cause trouble for this world.

After taking one last look at the blue spider lilies that resembled burdock, Yuko left with Yoriichi.
