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

It wasn't until Tanjiro and the others returned after lunch that it was already late afternoon, almost evening.

When Tanjiro returned, he was slightly taken aback when he saw the two still sitting in the corridor, then excitedly strode over.

Shinobu Kocho pulled Kanao aside with concern: "What happened? Why are you so late?"

The child seemed a little dazed; it was hard to tell if he had been frightened by the group of people.

Tanjiro, on the other hand, straightforwardly approached Ikuko.

"Miss Yuko!"

"Huh?" Why is this child so excited?

"Does the Sun Breathing technique have a thirteenth form?"

Yuko's mind went blank for a moment, then she looked at Tanjiro with clear eyes: "Didn't I tell you?"

"what?"

Yuko explained, "It's from the First Form of the Round Dance all the way to the Twelfth Form of the Flame Dance. You see, isn't the name a homonym?"

Tanjiro was dumbfounded: "Is that so?"

"Ah."

It was a bit too simple, which almost made Tanjiro question his life. He thought it was some kind of super powerful technique, but he just couldn't master it yet, which was why Miss Yuko wouldn't teach it to him.

I didn't expect it was just a matter of forgetting...

Actually, you can't entirely blame Yuko, because strictly speaking, it can't be considered an independent sword type.

To be able to unleash all twelve forms in an instant like Yoriichi is simply beyond the capabilities of humans.

Perhaps she could try it after she turned into a demon, but the damage that breathing technique would cause her movements to become extremely stiff.

This stiffness is harmless in other situations, but it will be magnified when facing opponents of the same or even higher level.

They learned from Tanjiro that they had been invited by Kyojuro after lunch.

The Rengoku family is not far from the Butterfly Mansion. The Water and Fire Breathing techniques are considered the mainstays of the Demon Slayer Corps, and almost every generation produces a Flame Pillar and a Water Pillar.

The Purgatory family is practically a family lineage, with most of the Flame Pillars coming from their family.

So Kyojuro took everyone over for a tour, and even dragged Kanao along.

Upon arriving at the Rengoku family residence, Kyojuro's father recognized Tanjiro's identity based on his earring.

At this point, Tanjiro couldn't help but ask, "Miss Ikuko, did you also recognize me through this earring?"

"What...is your relationship with my family?"

He had wanted to ask this question for a long time.

They have the same red hair, could they be distant relatives or something?

Why does Miss Yuuko know his Hinokami Kagura? Why is Hinokami Kagura called the Breath of the Sun...?

Shinobu Kocho chimed in, "That's it, we were just talking about this."

They were just talking about Tanjiro.

Yuko was a little confused: "Didn't I tell you?"

Tanjiro: "..."

No!

Nothing at all!

He originally thought that Miss Yuko didn't tell him many things because she had her own reasons, but it turned out that he had simply forgotten!

Yuko scratched her hair: "I see. Well, I'll just say whatever comes to mind then."

Tanjiro said seriously, "Please be sure to be careful!"

"..."

“That earring was owned by my elder brother, Yoriichi Tsugikuni, the creator of the Breath of the Sun, during the Warring States period.”

Zenitsu: "The Warring States period?"

Inosuke: "Brother?"

Tanjiro: "So, Miss Ikuko's surname is Tsutomu?"

“I didn’t tell you…”

No! x3

Intimidated by the crowd's imposing manner, Yuko swallowed back the words she was about to say: "Anyway, that earring originally belonged to me..."

"Wait!" Zenitsu suddenly called out, looking shocked. "The Sengoku period? Isn't that several hundred years ago?"

"I'm a ghost, isn't that normal?"

Tamayo is several hundred years older than her...

Muzan was born in the Heian period, more than a thousand years ago.

Inosuke pointed at Yuuko with a dumbfounded look: "So, this girl is already an old woman who's several hundred years old?"

Zenitsu instinctively wanted to reply, but suddenly noticed the black mist rising beside him and decisively chose to keep quiet.

Inosuke looked at Zenitsu, puzzled: "Hey, did I say something wrong?"

As soon as he finished speaking, his whole body trembled as if he had been electrocuted.

Inosuke's blue pig-like eyes gleamed with wisdom as he muttered, "Did you guys feel it?"

"There was a very strong gaze, almost like being stared at by a wild beast..."

Everyone looked behind him and dared not utter a sound.

boom!

Inosuke lay on the ground with a red bump on his head and white foam coming out of his mouth.

Yu Zi's fist was still steaming as she calmly sat back down: "Ask me if you have any other questions."

The two shook their heads rapidly, their heads almost blurring out of focus.

Butterfly covered her mouth and chuckled.

Yuko rolled her eyes: "Anyway, Yoriichi and I knew Tanjiro's ancestor back in the Warring States period, and that earring was a gift from Yoriichi to your ancestor."

"The God of Fire...and the Breath of the Sun, too?"

"Yes, your ancestor was a very talented person. He only glanced at the sword shape and memorized it, and it has been passed down ever since."

This can only be described as a miracle.

"I see……"

He had assumed Miss Yuko was a distant relative of theirs...

So that's what happened.

Yu Zi raised her eyes: "What's wrong? You seem to have a problem?"

Tanjiro scratched his head: "No, I'm just a little confused..."

"Is there something wrong?"

"Well..." Tanjiro paused for a moment, then couldn't help but ask, "Miss Yuuko, do I really have the qualifications to practice Sun Breathing?"

Yuko raised an eyebrow: "Of course, you should be able to sense your own compatibility with Sun Breathing, right?"

“Indeed, it’s more comfortable than when I use Water Breathing, but…” Tanjiro hesitated, “Miss Ikuko, you once said that Sun Breathing is the most effective breathing technique against demons, but I haven’t been able to use it effectively at all, and its ability to control demon regeneration is extremely limited…”

Yuko opened her mouth, forcing a reassuring smile: "That's because you haven't mastered the Crimson Blade yet."

"Crimson Blade?"

"The technique of turning a Nichirin Blade red with grip strength is a skill that can only be learned after you have mastered the markings."

"It possesses the ability to suppress the regeneration of evil spirits and can perfectly utilize the effects of Sun Breathing."

She's lying...

The Breathing of the Sun inherently possesses the ability to suppress regeneration, but Tanjiro is simply too weak...

Even though they are both users of the Sun Breathing technique, their strengths are worlds apart; Tanjiro is far from being as powerful as Yoriichi.

People like Yoriichi are like shooting stars; they have nothing to do with breathing techniques. Even without using Sun Breathing, he could defeat Muzan.

Tanjiro looked at Ikuko's smile, hesitated for a moment, and then nodded.
