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

Chapter 549 Unparalleled Sword Skill

"Wait!" Kisuke Urahara raised his hand to interrupt, "What do you mean by the Transparent Domain?"

"Your ability?"

"That's it."

Kisuke Urahara stroked his chin: "I see, it's definitely worth studying."

Yu Zi raised the Shura in her hand: "How about it? My Zanpakuto?"

"Heh." Yoruichi Shihouin rolled her eyes at her first, then asked curiously, "By the way, why doesn't your sword have a handguard?"

Bai Xia's blade is connected to the hilt, but there is no guard in the middle, so it appears very long.

Generally, both Nichirin swords and katana have a tsuba, which is a handguard; otherwise, when clashing with other weapons, it would be easy for the opponent to cut one's hand.

“Oh, you mean the guard? Of course, that’s a good idea.” Yuko raised the Shura in her hand, and the blade seemed to wriggle twice as if it were alive, and a delicate tsuba (handguard) formed at the junction of the blade and the hilt.

Yoruichi Shihouin's golden pupils widened: "This sword, could it be..."

“That’s right, it’s made from my flesh and blood, and it can change shape at will.” As Yuko spoke, the slender blade, which was originally more than a meter long, extended out and directly reached in front of Urahara Kisuke.

It was stretched to about four meters.

Yoruichi's lips twitched: "Then why not make yourself a gauntlet?"

Yuko said with pride, "Because my swordsmanship has become so exquisite that I won't get hurt even if I don't need hand guards."

Yoruichi rolled her eyes, skipped over the topic, and asked, "Then, was that blood rose that looked like a whip just now your blood?"

"Yes, but that should be called Blood Demon Art. My Blood Demon Art is the ability to manipulate the blood within my body at will."

“I see.” Yoru’s eye twitched slightly. “In a sense, it is indeed very similar to the release of a Zanpakuto.”

Kisuke Urahara nodded silently: "Indeed, a strange and unusual ability."

Yuko retracted the length of the Shura and looked at Urahara Kisuke: "Let's continue. I also want to see what kind of being the so-called Shinigami is."

Kisuke Urahara smiled slightly: "Well, now that I know Yuuko's strength, I don't need to worry about it anymore."

"Okay, here I come."

Yuko assumed a fighting stance, her golden double pupils fixed on him without uttering a word.

Those eyes really were intimidating.

After muttering a few complaints to himself, Kisuke Urahara raised his Zanpakuto and chose to engage Ikuko in close combat.

After a brief sparring session with Yoruichi and Kisuke Urahara, Yuuko had roughly figured out that she, the Demon King, seemed to be lacking in both strength and speed.

This was the first time in so many years since Muzan's death that Ikuko had felt her heart racing.

If it weren't for the frenzied operation of the Transparent Domain, I might have already been defeated by the absolute numerical suppression.

No, it's not just about absolute numbers.

The fragile researcher in front of me, who looks like a science student, has surprisingly good swordsmanship, much better than Yoruichi.

As Ikuko's rival, Kisuke Urahara was also filled with shock.

Through this brief exchange, he could clearly feel that Yu Zi's swordsmanship was indeed as formidable as she had said, but she ultimately lacked the foundation of spiritual power, and was deficient in both speed and strength.

Logically speaking, in this situation, pure sword skills wouldn't be able to salvage much, yet Yuko was able to precisely block every single one of his attacks.

and……

It's not a reaction.

Rather, it was a prediction made in advance.

It's almost like they can see into the future.

Kisuke Urahara stopped his attack and asked the question that had been bothering him.

Yoruichi answered him.

"It's very simple. By observing the flow of blood, the movement of bones, and the movement of muscles, you can predict the enemy's attack methods in advance."

"Huh?" Kisuke Urahara was stunned for a moment. "What's that?"

"X-ray vision?"

Yuko nodded, then shook her head: "It's the Transparent Domain."

"However, it can indeed achieve a level similar to seeing through the human body, but of course, it is limited to the human body."

"It won't work if it's a wall."

"Hiss~" Kisuke Urahara gasped. "Demons are really something else."

"This has nothing to do with ghosts. Even humans can learn this skill."

"Humans, humankind? Then what about us?"

"You are also human souls, right? You should be able to as well, shouldn't you?"

Kisuke Urahara appeared in front of Ikuko at lightning speed: "Please teach me, Ikuko-sensei!"

Yuko paused for a moment, then patted him on the shoulder with delight: "Oh! Urahara-kun, you really are a studious person."

"Yes, yes! I'll be counting on your guidance, teacher!"

Yoruichi's face twitched as she watched, and she grabbed Urahara Kisuke by the collar.

"You idiot, you're so shameless!"

Kisuke Urahara looked puzzled: "Eh? Such an amazing technique, even Shinigami can learn it, doesn't Yoruichi want to?"

Yoruichi twitched the corner of her mouth: "...I don't want to!"

Unless that idiot begs her to learn!

Kisuke Urahara turned around and said, "It's okay, Ikuko-sensei, I can learn by myself."

"Who gave you permission to run away like that!"

Yoruichi angrily threw him out.

Yuko blinked and said, "It's okay, Yoruichi. If you want to learn, I can teach you."

Kisuke Urahara got up from the ground: "As expected of Ikuko-sensei, she has a broad mind."

"Haha, it's okay."

Yoruichi gritted her teeth in anger at the two of them putting on such a show, and really wanted to beat them up.

After laughing twice, Yu Zi's smile faded, and she said seriously, "However, I'm not sure if you can learn it."

"The Transparent Realm is actually a skill that naturally emerges after experiencing the great terror between life and death and honing martial arts to the pinnacle."

"Refine the martial arts?"

"Yes, of course, swordsmanship also counts."

"What constitutes reaching the pinnacle?"

Whether it's martial arts or anything else, there will never be a strongest person in this world, only someone stronger.

"Well..." Yuko shook her head, "It's hard for me to explain clearly either."

"However, one thing that can be confirmed is that high-intensity combat is the key to unlocking the Transparent Domain."

"This technique requires the user to constantly teeter between life and death, experiencing extreme pain."

"Of course, the most important thing is precise control over one's breathing."

Kisuke Urahara frowned: "Breathing?"

How did this get related to breathing again?

Yuko nodded and explained, "Whether it's fighting or any other action, it will consume physical strength, and proper breathing is beneficial to improving endurance and the intensity of the action."

“Indeed, adjusting one’s breathing is of great help in combat.” Kisuke Urahara nodded slightly, agreeing with this theory.

Yuko raised an index finger: "This leads to a new technique called the art of breathing."

"Breathing technique?"

The clash of abilities from the two worlds caused Yoruichi to fall silent.

"That's right, breathing techniques, or breathing methods."

"Proper breathing techniques can bring considerable benefits to combat, and can even control the flow of blood and oxygen in the body through breathing, thus greatly improving physical condition."

"Through this technique, ordinary people can master the skill of slaying demons."

Seeing Kisuke Urahara frowning in thought, and Yoruichi looking as if she were listening to gibberish, Ikuko paused for a moment.

"This may be difficult to understand, so let me demonstrate it to you in a more intuitive way."

Yuko arrived at the center of the dojo, closed her eyes, and gently adjusted her breathing.

"This is a breathing technique I created myself, called Snow Breathing."

As her voice faded, Yu Zi took a deep breath, and then the Shura sword in her hand suddenly shot out.

"Snow Breathing - First Form: Tornado!"

A snow-white tornado suddenly rose up inside the dojo.

"What's the principle behind it?!" Kisuke Urahara covered his face to shield himself from the fierce wind, his expression one of utter shock. "Is this something a human could do?!"

Yuko did not stop because of his words, and continued to perform the sword form of Snow Breathing.

From the first form of the tornado to the tenth form of the karuzuki under the snow.

A huge white jade disc rolled across the floor and embedded itself into the wall beside it.

The two people's eyes were almost bulging out.

"Phew, that's about it." Yu Zi suppressed her aura and put away the Shura.

Yoruichi raised her hand with a blank expression.

"Is there a problem, Yoruichi-kun?"

Yoruichi asked blankly, "You mean, humans can learn to do this kind of thing?"

Yuko nodded: "That's right, ordinary humans can achieve the same effect by using weapons."

"If my Blood Demon Art is incorporated, the power and range of the sword will be further enhanced."

Yoruichi grabbed her hair: "Is this something a human could do?"

"Teach me, Ms. Yuuko!" Compared to Yoruichi's frustration, Kisuke Urahara was quite direct.

"I will teach you, but I don't know if you can learn it."

Kisuke Urahara understood what she meant: "If it's just related to breathing techniques, it should be fine!"

Yoruichi covered her face, somewhat speechless: "Seriously, weren't we here to teach you how to develop your spiritual power?"

Yuko paused for a moment, then realized what she meant: "That's what I meant!"

"Teach me quickly how to unleash my Zanpakuto."

As Yuko spoke, she gestured with the Shura in her hand.

Yoruichi was speechless: "No, this ordinary knife won't work."

"Eh?"

"Didn't I say that Zanpakuto must be trained by Asauchi?"

"But releasing the Zanpakuto is really cool."

"Even if he's handsome, there's nothing you can do about it."

Kisuke Urahara suggested, "How about trying Kido?"

"Ghost path?"

“That’s right, Kido, the fighting style of Shinigami, can be roughly divided into Slash, Fist, and Oni,” Kisuke Urahara explained. “These are Kendo, Hakuda, Shunpo, and Kido respectively.”

"Among them, the Kido is the most complex, which uses incantations to transform spiritual power into various forms to attack enemies. The Kido is further divided into the Hado, which attacks enemies, the Bakudo, which binds enemies, and the Huido, which heals others."

"for example."

Kisuke Urahara raised his hand and pointed it at the wall beside him.

"Hado No. 4, White Lightning".

A bolt of lightning suddenly shot out from Kisuke Urahara's fingertips, turning the wooden wall black with electricity.

Yuko's eyes lit up: "Teacher! I want to learn this!"

"Haha, of course~ This is the first time I've been called 'teacher'." Kisuke Urahara scratched his head.

Yoruichi's lips twitched. These two idiots.

……

So, in the days that followed, the three of them learned from each other.

Yoruichi and Kisuke Urahara were responsible for teaching Ikuko how to control her spiritual power and learn Kido, while Ikuko taught them breathing techniques.

Of course, since Kisuke Urahara was the captain of the 12th Division, he was often away, so Yoruichi usually taught Ikuko.

As for why Yoruichi is so free?

When Yuuko asked this, Yoruichi almost got a hair on her head: "Idle? Where am I idle? I'm very busy, okay! Don't talk nonsense!"

"Lord Yoruichi, are these the documents you need to sign, or should I hand them over to Vice Captain Ōmaeda?" At that moment, a servant came over carrying a stack of documents and asked.

Yoruichi swallowed hard, turned to look at Yuuko, only to see Yuuko looking at her with disdain, as if she had been stepped on. She quickly snatched the document away.

"What Ōmaeda? I don't even know him! Besides me, the team leader, is there anyone else who can handle these documents?"

The servants nodded repeatedly.

However, after Yuko returned to her room, she secretly summoned a servant and slipped the documents to her.

"Give it to Ōmaeda."

"..."

……

"Hey, Yoruichi, who's the strongest one here?" After training, Yuko lay on the dojo floor, calmly looking at the ceiling.

Yoruichi lay down next to her: "Old man Yamamoto, right? The captain of the First Division."

Yuko was somewhat surprised: "You're the captain of the Second Division, doesn't that mean you're second only to the leader?"

"But why don't I feel like you're better than Kisuke?"

Yoruichi was speechless: "First of all, the squad number doesn't represent strength. Secondly, I'm definitely stronger than Kisuke."

"How powerful is that old man Yamamoto?"

"Extremely powerful, hailed as the strongest Shinigami in a thousand years. His spiritual pressure alone, when he gets serious, can make even the captain breathless."

"so smart?"

"To be honest, even if Yuuko were to face him, she might die." Yoruichi sat up. "That old man's Zanpakuto has the ability to burn everything to ashes."

Yuko paused for a moment, then said, "Then you suggest I ask him for help..."

Yoruichi, her face darkening, dragged her up from the ground: "Can't you be a little more sensible?"

Yu Zi chuckled and said, "Sorry, sorry, just kidding."

Yoruichi grumbled, "Honestly, old man Yamamoto is over a thousand years old and still living a good life. You, a six-hundred-year-old, shouldn't you stop thinking about dying all the time?"

Yuko's eyes lit up: "So you really admit I'm young now, huh?"

"Whatever makes you happy." Ye opened her mouth, but was somewhat speechless.

Then, she raised her chin, indicating, "Come with me."

"What?"

I have something for you.

"Things?" Yu Zi got up from the ground, shook her head, and followed.
