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

When humans are admired, they carefully maintain their character.

They don't want their bad side to be seen by those they admire.

After a long silence, Yan Sheng spoke softly, "What is there to entrust with someone like me?"

Yuko looked down at him and answered irrelevantly, "I know, brother dislikes Yoriichi, right?"

Upon hearing this, Yan Sheng's eyes narrowed slightly, and he subconsciously looked away from Yu Zi's gaze.

It was as if he had stripped naked in front of Yuko, with no secrets whatsoever.

Yuko didn't seem to mind and said gently, "I'm actually quite envious... no, I should say I'm jealous, jealous of Yoriichi's talent."

"That innate talent is something that no one else can catch up to."

Iwakatsu's lips parted slightly, revealing his surprise for the first time in front of Ikuko.

This is precisely Yuko's treatment method.

The first step is to help Yansheng build self-esteem.

The second step is to let Yan Sheng know that there are people who share his views, and that they are all ordinary people who have been bullied by the genius Yoriichi.

Some things are hard to keep to yourself, but if you can share them with someone, it won't be so hard, especially if you can empathize with them.

That's why the people you can hang out with are usually your classmates and colleagues.

Because everyone shares the same stance.

It was only today that Yan Sheng saw that his younger sister had such a gentle face.

As expected, it's because...

He stared at Yuko for a moment, noticing the fine beads of cold sweat on her forehead.

As expected... Yuko suppressed her pain throughout her battle with him.

Yan Sheng was unusually overcome with a sense of guilt.

Yuko took out the wooden flute that she had been hanging around her neck from her chest.

Yan Sheng was slightly taken aback. She still had it with her?

Yuko had never worn it around her neck before; she always kept it in her bag.

She brought it on purpose this time for PUA Yan Sheng.

Holding the wooden flute, Yuko smiled and said, "Brother, please carry Yuko's dream and strive to catch up with Yoriichi."

"Ahem... I will cheer on my brother."

then……

Let's leave this world together after we turn twenty-five.

Having been given a second chance at life, she was truly content.

……

Three years have passed since then.

Yoriichi felt that his older brother seemed to have changed.

Mingming's older brother is still working hard to train as before, and he hasn't changed at all.

But Yoriichi just felt that way for some reason.

"I lost." Iwakatsu sheathed his Nichirin Blade and calmly accepted his defeat.

Yoriichi said gently, "Brother's skills have improved again."

Seeing that they had finished their competition, Yu Zi waved to the two of them and said, "Brother, come and have some tea."

She poured the tea and served it to the two of them.

Yoriichi took a small bite and praised, "Yuko's cooking skills have improved too."

Yu Zi rolled her eyes at him: "Yuan Yi, can't you change what you're saying?"

"It's always the same line."

Yoriichi smiled and said, "How are you feeling? The doctor told me to keep an eye on you and not let you jump around like that."

Yu Zi was exasperated: "What kind of personality do other people see me as?"

Yan Sheng sipped his tea and said casually, "Monkey."

“??” Yuko looked at him with an incredulous expression.

Iwakatsu ignored it.

Watching the two playfully interacting, Yoriichi first smiled, then unconsciously used his clairvoyant vision to see the condition of Ikuko's lungs. He lowered his eyes, his expression full of apology, and said:

"I'm sorry, Yuko. I wish I had been there for you back then."

Yu Zi paused for a moment, then realized what he was talking about, and shook her head with a smile.

"That was originally my task; I was just too careless."

"It's okay, I just sometimes can't help but cough, but it won't affect my normal life."

Since then, Ikuko, who had difficulty using the breathing techniques, stepped down from the front lines of the Demon Slayer Corps and took charge of logistical maintenance.

Occasionally, she would instruct newcomers on swordsmanship, which allowed her to experience the thrill of being a teacher.

Hearing Yuko say this, Yoriichi felt a little relieved.

Iwakatsu, unwilling to discuss Ikuko's illness, changed the subject, saying, "More and more swordsmen are awakening their Demon Slayer Marks, and the Demon Slayer Corps is growing stronger every day."

"Perhaps the struggle between humans and ghosts will end in our generation."

Yuan nodded: "Yes, there have been far fewer traces of ghosts lately."

Without a doubt, both the birth of the Breathing Technique and the awakening of the Demon Slayer Mark made the Demon Slayer Corps stronger than ever before, and at one point it curbed the growth of demons.

The two brothers remain optimistic, but Yuko fell silent after hearing this.

More and more members of the Demon Slayer Corps are awakening their Demon Slayer Marks, and all of the original Pillars now have them.

After awakening his mark, Iwakatsu quickly mastered the abilities of the Crimson Blade and the Transparent World, becoming the second person after Yoriichi to master the three-piece set.

Yuko, on the other hand, can only enter that transparent world occasionally, and it's not very stable.

As for the Crimson Blade, which relies on grip strength to unleash the solar energy within the Nichirin Blade, even though Ikuko had awakened her Mark and her physical abilities had improved, her grip strength was still insufficient to change the color of the Nichirin Blade.

She has fallen far behind her two older brothers.

The two brothers are far ahead of the entire Demon Slayer Corps in terms of skill level.

At that time, the three siblings stood on the back hill gazing into the distance.

"No one's strength can match ours; the inheritance of breathing techniques is simply hopeless."

"If this continues, the exquisite skills honed through countless trials will be lost."

Unlike Iwakatsu's worries, Yoriichi remained calm, smiling as he said:

"Brother, you think too highly of us."

"You and I are just two passersby in the long history of humankind."

“A baby whose talent far surpasses ours may be born somewhere in the world right now.”

"I suppose they will eventually reach the same level as you and me."

"There's no need to worry too much. We just need to let things take their course and wait for the day when life gets lonely."

Hearing these words, Iwakatsu's heart, which had finally begun to change because of Ikuko, sank into despair once again.

'Yoriichi, every time you smile, I feel incredibly disgusted.'

'When discussing heavy topics like the impending extinction of breathing techniques, you maintain that strange optimism... and even laugh...'

Yuko looked at her two older brothers and opened her mouth, but ultimately couldn't say anything.

Actually, she had already figured it out.

Yoriichi completely ignored his brother's opinion of him, which is also a kind of "indifference" that geniuses have towards ordinary people.

When a genius openly discusses his ordinariness, how can those who are chasing after him remain calm?

This year, Yuko is twenty-three years old, and her two older brothers are twenty-four years old.

……

The swordsman who awakened his markings died.

At first, everyone thought it was a sudden death caused by overtraining.

Not long after, another swordsman with the markings died suddenly, the day after his twenty-sixth birthday.

Even among the first Pillars who awakened their markings, some lost their lives as a result.

The Demon Slayer Corps only then noticed that those who died suddenly were all swordsmen who had awakened their Demon Slayer Marks.

And they all have one thing in common.

Over twenty-five years old.

Skin markings are a way of borrowing life from heaven, a way of pre-drawing on one's lifespan; people who develop skin markings will not live past the age of twenty-five.

Such words gradually began to circulate within the Demon Slayer Corps.
