Older Brother, Hungry Hungry~

Tanjiki watched with rapt attention, as if trying to imprint every movement into his eyes.

Noticing his expression, Yuko suddenly understood.

The sword forms of Sun Breathing, so beautiful they made one forget to breathe, Yoriichi moved like a spirit dancing in flames.

This must be how the Kagura dance, passed down through Tanjiro's family for generations, had been preserved.

All the forms of Sun Breathing were firmly etched into Tanjiki's pupils.

After the dance, Tamiko, holding her daughter, happily praised Yoriichi's sword forms.

Yoriichi lowered his head as if embarrassed.

Tanjiki said excitedly, "Mr. Yoriichi, Miss Yuko, please visit often when you have time!"

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

Tanjiki solemnly accepted the earring with both hands, he had a premonition.

Mr. Yoriichi probably wouldn't be coming back.

"Mr. Yoriichi! We will pass it on... with this life you saved..."

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

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

"I won't allow anyone to say that, I..."

"I swear to you, I will pass this earring and Sun Breathing down to future generations!"

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

They were both gentle people.

Yuko saw the sadness in his heart and comforted him, "Don't worry, we'll come visit often."

She still hadn't found her Higanbana.

She would definitely come back.

"Miss Yuko..." Seeing Yuko's gentle smile, Tanjiki was momentarily stunned before he realized.

Mr. Yoriichi wasn't alone.

Tanjiki's lips moved slightly, "Miss Yuko, I'll be entrusting Mr. Yoriichi to you."

"Yes, please leave it to me."

Just then, Yoriichi gently turned his head.

"Thank you."

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

"Brother, I'm hungry~"

Yoriichi: "..."

What kind of adorable creature was this.

After feeding his sister, Yuko treated Yoriichi's wounds.

"Brother." Yuko looked at Yoriichi with a serious expression.

"What is it?" Yoriichi lowered his sleeve and looked over curiously.

"Since Muzan probably won't appear again, I want to make some preparations for the future."

"What?"

Yoriichi fetched paper and a brush.

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

"If I can draw it, I think it will help with..."

Before she could finish, Yoriichi's calm voice cut in.

"There's no need..."

A vein throbbed on Yuko's forehead.

"Brother."

"Hmm?"

Yuko flashed a deathly smile. "Do you know? Brooding handsome guys like you are already out of fashion."

"?"

Yuko's smile gradually faded, and she said sadly, "Why do you always like to take all the responsibility on yourself?"

"It's not your fault."

Yoriichi merely lowered his eyelids slightly at her words.

Words of comfort...

For adults, they aren't very effective...

You can encourage a child who's disappointed after failing a test by telling them to try harder next time.

But for an adult, such encouragement is difficult to achieve, and the only way to comfort them is through success.

However, Yoriichi's failure to protect his family and kill Muzan was an unchangeable fact.

For a loser in a situation that has already failed and cannot be salvaged, words of encouragement are useless.

Yuko suddenly said, "Leave it to me."

"?" Yoriichi looked up, confused.

"The task of slaying Muzan," Yuko said, looking at him solemnly, "No matter how many years it takes, I will definitely fulfill Older Brother's unfulfilled wish."

Those who pursue the Way to its end arrive at the same destination.

This saying sounds profound, but it actually defined Yoriichi's entire life of 'incompetence.'

Those who delve deeply into a path will eventually reach the same place.

This is the same as believing in the wisdom of future generations, which is a mistake.

Or rather, it's too one-sided.

Human development has never been horizontal.

If past generations don't do everything they can to pass down knowledge, future generations will be unable to develop at all.

The thousands of years of human history are not the talent of one person or a group of people, but the collective effort of everyone.

People, big or small, influence everything around them.

In Yuko's eyes, Yoriichi was escaping his 'incompetent' life, feeling self-abandoning.

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

Someone stronger than me might have been born by now, etc. It doesn't matter if I pass down the breathing techniques or not.

Yoriichi was a kind person, but also a cowardly one.

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

After she said those words, Yoriichi had fallen into a daze.

Was he moved by her?

Well, that's normal.

After all, these were PUA techniques hundreds of years ahead of their time; an ordinary person couldn't handle them.

Yoriichi stared blankly at Yuko, tears welling up in his eyes.

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

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

"It's okay, Older Brother, you've already done very well."

"I'll take care of the rest."

"Seven hearts, five brains..." Looking at the structural diagram Yoriichi had drawn, Yuko couldn't help but comment, "This guy is quite something."

"So, to kill him, you have to sever all twelve of his weak points in an instant?"

"I'm afraid not," Yoriichi shook his head, a hint of disappointment in his eyes. "At the time, my sword strike had completely severed his weak points, but he didn't die."

This was also the direct reason why Yoriichi hadn't foreseen that Muzan had a backup plan.

Yuko said dully, "So... only the sun?"

Yoriichi was about to nod, but hesitated and then shook his head again. "At that moment, he suddenly split into over 1,800 pieces of flesh."

"I think if I had been able to completely chop up those pieces of flesh at the time, he might not have been able to recover."

"Sever his neck along with the twelve weak points, and then obliterate the fragmented flesh," Yuko murmured, her mouth twitching slightly. "I think there's a better chance of just waiting until dawn."

She admitted that even if she became a demon and her physical abilities were greatly enhanced, along with the bonus from her Blood Demon Art, she would still not be Yoriichi's match.

Even if Muzan wasn't as strong as Yoriichi, he was by no means someone they could compare to.

Because, as far as she knew, the Demon Slayer Corps defeating Muzan was considered a plot device by many.

In other words, even Tanjiro and the others couldn't defeat Muzan head-on.

Plot devices were a peculiar setting, and Yuko couldn't calmly wait for the happy ending of Muzan's execution to arrive.

Because it was possible that due to her influence as an outsider, certain things had already changed.

The consequences brought about by the butterfly effect had to be guarded against.
