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

Tanji watched intently, as if trying to imprint every movement in his eyes.

Noticing his expression, Yuko suddenly understood.

The breath of the sun, with its sword shape so beautiful it makes one forget to breathe, made Yoriichi seem like a spirit dancing in the fire.

This is probably how the Kagura dance, passed down through generations of Tanjiro's family, has been preserved.

Tanjiro had firmly imprinted all the techniques of Sun Breathing into his pupils.

After the dance, Zhu Miko held her daughter and happily praised Yoriichi's sword technique.

Yoriichi lowered his head as if embarrassed.

Tanji said excitedly, "Mr. Yoriichi, Ms. Yuko, you must come and visit often when you have time."

Yoriichi didn't say much, but suddenly took off his earring and gave it to Tanjiro.

Tanji solemnly accepted the earrings with both hands; he had a premonition.

Mr. Yoriichi probably won't be coming again.

“Mr. Yoriichi! We will carry on this legacy… with the life you saved…”

Tanji suddenly took two steps forward and shouted with all his might.

"You are definitely not a worthless person, please don't think that you've accomplished nothing!"

“I will never allow anyone to say that, I…”

"I swear to you that I will pass on these earrings and the breath of the sun to future generations!"

For a fleeting moment, his figure overlapped in Yuko's eyes with that of a boy with a scar on his forehead.

They are all gentle people.

Yuko noticed his sadness and comforted him, "Don't worry, we'll come often."

She hasn't found the red spider lily yet.

We'll definitely come again.

"Miss Yuko..." Tanji was momentarily stunned when he saw Yuko's gentle smile before he realized what was happening.

Mr. Yoriichi is not alone.

Tanji's lips moved slightly: "Miss Yuko, I'm entrusting Mr. Yoriichi to you."

"Yes, please feel free to leave it to me."

Just then, Yoriichi turned around gently.

"thank you all."

……

The two returned home together, and as soon as they entered, Yuko collapsed onto the tatami mat.

"Brother, I'm hungry~"

Yoriichi: "..."

What exactly is this adorable creature?

After feeding her younger sister, Yuko healed Yoriichi's wounds.

“Brother.” Yuko looked at Yoriichi with a solemn expression.

"What's wrong?" Yoriichi lowered his sleeve and looked at him with a puzzled expression.

"Since Muzan is unlikely to reappear, I want to make some preparations for the future."

"what?"

Yoriichi found paper and pen.

"Brother, do you still remember Muzan's physical structure clearly?"

"If I could draw it, I would like to..."

Before she could finish speaking, Yoriichi spoke softly.

"There's no need..."

A vein appeared on Yu Zi's forehead.

"Brother."

"Ok?"

Yuko gave a deathly smile: "You know what? Melancholy beauties like you are out of fashion now."

"?"

Yuko's upturned lips gradually faded, and she said sadly, "Why do you always like to take the blame upon yourself?"

"It's clearly not my brother's fault."

Upon hearing this, Yoriichi simply lowered his eyelids slightly.

Words of comfort...

It's actually not very effective for adults...

When a child is disappointed after doing poorly on a test, you can encourage them with words like "try harder next time."

But for an adult, such encouragement is unlikely to be effective. There is only one way to comfort them: success.

However, the fact that Yoriichi failed to protect his family and kill Muzan is undeniable.

There's no point in offering words of encouragement to someone who has already failed and has no chance of recovery.

Yuko suddenly said, "Leave it to me."

"?" Yoriichi looked up, puzzled.

"The mission to kill Muzan." Yuko looked at him solemnly. "No matter how many years it takes, I will definitely fulfill my brother's unfulfilled wish."

Those who exhaust their paths will ultimately find the same destination.

This statement sounds profound, but it actually encapsulates Yoriichi's 'incompetence' throughout his life.

Those who delve deeply into the path will eventually arrive at the same place.

This is the same as believing in the wisdom of later generations, which is wrong.

Or rather, it's too one-sided.

Human development has never been horizontal.

If our predecessors don't do everything they can to pass on their knowledge, future generations simply won't be able to develop.

Human history spanning thousands of years is not the result of the talent of any one person or group, but rather the collective effort of everyone.

People, whether big or small, influence everything around them.

In Yuko's view, Yoriichi was escaping his 'incompetent' life, and there was a sense of self-abandonment.

Anyway, I'm so useless that I can't do anything at all.

Someone stronger than me might be born right now, etc. It doesn't matter whether I pass on the breathing technique or not.

Yoriichi is a gentle person, but also a cowardly one.

"Brother? Brother, can you hear me?" Yuko tilted her head and waved it in front of Yoriichi.

After she said those words, Yoriichi fell into a daze.

Were you moved by her?

Well, that's normal.

After all, this is a PUA technique that is hundreds of years ahead of its time, and most people can't resist it.

Yoriichi stared blankly at Yuuko, tears welling in his eyes.

While Yuko was still in a daze, Yoriichi suddenly hugged her tightly.

Yuko was surprised for a moment, then gently patted his back and said softly.

"It's alright, brother has already done very well."

"Leave the rest to me."

……

"Seven hearts, five brains..." Looking at the structural diagram that Yoriichi had finished drawing, Yuko couldn't help but complain, "This guy is really amazing."

"So, to kill him, you have to eliminate all twelve of his weaknesses in an instant?"

“I’m afraid not.” Yoriichi shook his head, a hint of disappointment in his eyes. “At that time, my sword technique had completely severed his weakness, but he did not die.”

This is also the direct reason why Yoriichi did not expect Muzan to have a backup plan.

Yuko said somberly, "So... there's only the sun?"

Yoriichi was about to nod, but hesitated and shook his head: "At that time, he suddenly split into more than 1,800 pieces of flesh."

“I think if I had been able to completely shred those pieces of flesh, he might not have been able to recover.”

“Cut his neck and all twelve weak points, then destroy the pieces of flesh.” Yuko murmured, her lips twitching slightly. “I feel there’s a better chance of holding out until dawn.”

She believed that even if she became a demon and her physical abilities were greatly enhanced, and with the added bonus of Blood Demon Art, she would still be no match for Yoriichi.

Even if Muzan is not as good as Yoriichi, he is still far superior to them.

As far as she knew, many people said that the Demon Slayer Corps was able to defeat Muzan because it was a plot device.

In other words, even Tanjiro and his companions were unable to kill Muzan head-on.

The plot-driven death is a peculiar setting that makes it impossible for Yuko to calmly wait for the happy ending of Muzan's defeat.

Because perhaps, under her influence as an outsider, some things have already changed.

The consequences of the butterfly effect must be guarded against.
