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

Yu Zi knelt down on the spot, put her hands together, closed her eyes slightly and lowered her head.

Although it was called a memorial service, she actually had nothing to confide in anyone.

Muzan is still living a carefree life in the world. After defeating Muzan, she can come back and renovate this place.

Nezuko thoughtfully knelt down after Yuuko, clasped her hands together, and offered a devout prayer.

After the prayers, Yuko began searching for a place to hide near Tanjiro's house for the night.

The place has changed considerably compared to hundreds of years ago, but the best place to hide is still the grove of trees in front of the house.

It's winter now, and the snow covers everything, so you can't tell if you're lying in the ground.

If dealing with a sharp-witted swordsman like Yoriichi, perhaps they could detect it.

But all Muzan possesses are absolute numbers; he doesn't have the keen sense of danger that a qualified swordsman or warrior would have.

As long as you conceal your presence well, Muzan shouldn't be able to detect anything.

Moreover, although Yuko lacked confidence in defeating Muzan, she was still somewhat confident in escaping from him.

Seeing her completely buried in the snow, Nezuko couldn't help but worry, "Won't you catch a cold?"

Yu Zi stood up from the snow and said with a smile, "No, I practice martial arts all year round, this kind of cold is nothing to me."

On the contrary, having adapted to her ghostly form, she now prefers the cold environment to the scorching summer.

In this cold environment, the power of her sword is greatly enhanced.

This is also why Yuko is confident that she can operate under Muzan's nose.

This is exactly what it means to be like a fish in water.

Nezuko was still a little worried, but seeing that Ikuko had been lying in the snow for so long without even shivering, she believed her.

As evening quietly approached, Nezuko brought out two bowls of food.

"Sister Yuzi, dinner's ready."

"Ah, I see."

Yuko was scouting outside when she heard Nezuko's voice and felt a little helpless.

She had already told her in advance that she didn't need to be cooked, but Nezuko insisted that she needed to eat to have the strength to fight, giving her no chance to refuse or explain.

Nezuko's cooking skills are quite good; the food looks delicious.

In this era, children from poor families learn to be independent early. When Yu Zi was her age, she had never cooked a meal.

Yuko ate a little bit, and she only found out about it after she met Tamayo.

Evil spirits cannot eat human food; it would be unpalatable to them.

However, after becoming a demon, Yuuko was able to barely eat cooked human food, which may be related to her constitution.

Mastering the five breathing techniques is not a simple matter.

There are quite a few swordsmen in the Demon Slayer Corps who have mastered various breathing techniques, especially those who have derived breathing techniques. They know a little bit about basic breathing techniques, but they cannot switch between breathing techniques at will during battle.

But Yuko can.

After dinner, Yuko noticed Nezuko's worried expression and was moved by it.

Of course, anyone would be afraid.

She couldn't offer any words of comfort.

Because deep down, Yuuko was even more supportive of Nezuko becoming a demon.

It's not just about adding another fighting force; you have to understand that Nezuko is practically a main character, and she could very well play a crucial role in the final battle.

Yuko silently apologized, said goodbye to Nezuko, and left home.

She felt like a petty person, just like before, deceiving Yan Sheng, knowing full well his fate but still choosing to hide it.

The same thing is true now; talk is better than action.

She wasn't a dazzling sun like Yoriichi, not even the moon, not a star... Perhaps, describing her as the bottom of a swamp would be more fitting...

Yuko found a secluded spot in the snow-covered woods and lay down, covering herself completely in the cold snow. The cool snow calmed her restless heart.

Yuko calmed down.

……

Late at night, a man wearing a black trench coat appeared at Tanjiro's door.

In the snowy forest, a gaze was fixed intently on that figure.

The figure was not burly; in fact, he looked rather thin.

but……

What terrifying vitality...

This was the first time Yuko had seen Muzan in person.

Beneath the transparent barrier, Muzan's physical structure was laid bare.

Composed of five brains and seven hearts, this powerful body possesses a vitality like a raging volcano, ready to erupt at any moment.

She has overcome the shortcomings of sunlight, but in terms of physical fitness, even in her full-fledged demon form, she is far less vigorous than she is now.

That's only natural; she simply overcame the sunlight, but Muzan... is the Demon King.

The source of evil spirits in the world.

This is a monster that no one can defeat...

Yuko knew this clearly.

In terms of life level alone, Muzan has completely surpassed humanity.

If Yoriichi is like a highly skilled gamer, then Muzan is like a whale with god-tier gear and overpowered stats.

His basic data is on a completely different level from everyone else's.

To be honest, this is because the individual strength is too great, so much so that even a brainless idiot like Muzan can wreak havoc on the world.

In any other shonen manga, he wouldn't be a suitable villain.

They lack the strategic vision and intelligence expected of villains.

This is a pure numerical monster.

Muzan walked towards the door, and Yuko held her breath, her fingers slowly moving from beneath the snow to the hilt of her sword.

At this distance, if Muzan were to take any unplanned action against Nezuko, she would be able to reach her in an instant.

Muzan knocked on the door very politely.

"Excuse me, who is this?" Nezuko's slightly nervous voice came from inside the house.

The door is opened.

Muzan showed no intention of speaking to her. He glanced around and let out a soft "Huh?": "Is there only one person?"

"that……"

Muzan withdrew his scrutinizing gaze, his red eyes looking at Nezuko without a trace of emotion.

"If there is only one person, you have to take extra care of them."

Yuko breathed a sigh of relief, and her fingers, which had been resting on the knife handle, involuntarily loosened.

It's not a conspiracy theory.

"...What?" Nezuko was so nervous that she didn't dare to breathe.

Muzan said no more, his arm transforming into a long whip, which he then injected into Nezuko's body.

A moment later, Muzan coldly looked at Nezuko lying on the ground.

"It's already too weak after only a little blood. It seems that ghosts that can withstand sunlight are not so easy to create."

Muzan did not notice anyone spying on him in the dark. Just as Yuko had guessed, he did not possess the keen senses that a warrior should have; he was merely an ordinary person with an overpowered stat.

After confirming that Muzan had left, Yuko quickly got up from the snow and ran into the house.

Nezuko was lying in a pool of blood at the doorway.

Yuko went forward to check on Nezuko, who was unconscious, but her wounds were slowly healing.

Success...

Muzan turned people into demons in order to create demons that could withstand sunlight. Most of the humans who died at his hands were actually people who could not withstand his blood, rather than people who died directly from his attacks.

This is why Ikuko dared to let Nezuko face Muzan alone, although... it's not exactly something to be praised...

If she could be a little stronger...

Nezuko is turning into a demon.

The time it takes to become a ghost depends on one's own strength; it took her a full three days to become a ghost.

As for Nezuko, Tanjiro returned the next morning.

One night.
