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

Chapter 629 This is called prevention is better than cure.

"call……"

Yuko let out a soft breath and thrust her Zanpakuto at Kurosaki Masaki.

This scene almost made Ishida Ryugen and the other man lose their balance, but fortunately the tip of the knife stopped steadily between Kurosaki Masaki's eyebrows.

"Disorder, formless butterfly."

As Ikuko pressed the tip of the knife against Masaki Kurosaki's forehead, she softly chanted.

"Interference and Virtualization Balance"

A peculiar wave emanated from the Zanpakuto's blade, reaching its tip and then forming a ripple that gradually enveloped Masaki Kurosaki's entire body.

"If the ethereal soul is not dealt with, when the symptoms worsen, it will manifest as a state where the original soul and the ethereal soul coexist, which is to say, a monster that has lost its mind."

"In the end, not only the boundaries between souls will be broken, but even the boundaries between the soul itself and the outside world will be destroyed, leading to self-destruction without the control of its own will."

"This is soul suicide."

Shiba Isshin scratched his head: "I don't understand!"

"Simply put, the fusion of the two souls failed, and the souls themselves disintegrated."

Kisuke Urahara explained to the two in detail: "Yuko has the ability to interfere with the balance of their souls, which can directly eliminate the risk of soul suicide and bring a certain degree of peace to the beaten soul."

Ryūgen Ishida understood: "So, there's still no way to solve the problem?"

"Well……"

As Yuko's abilities unfolded, Masaki Kurosaki's tightly furrowed brows gradually relaxed.

"He hasn't woken up; he's just temporarily calmed down the soul within him." Yuko sheathed her Zanpakuto and looked at Kisuke Urahara. "Can you, like Hirako and the others, gain control of your body by defeating the Hollows in your inner world?"

“I’m sorry, I don’t know either.” Kisuke Urahara shook his head. “This is the first time I’ve encountered a Quincy Hollowfied.”

"However, I think one thing is for sure."

"what?"

"The opposite of Hollows is humanity, and the opposite of Shinigami is the Quincy." Kisuke Urahara raised his head slightly. "Just like cold water can neutralize hot water, and hot water can neutralize cold water."

"As long as you directly inject a soul that is the opposite of the ethereal, you can balance the boundaries of the soul."

Yuko paused for a moment: "So... the Grim Reaper?"

Yuko asked, somewhat puzzled, "Why are Shinigami and Quincy considered opposites?"

"Is it because one explores power inward, while the other grasps power outward?" Yuko muttered to herself. "But to me, they don't seem like opposites, do they?"

This only shows that the two sides have different views on how to use spirit particles; it doesn't mean that one side is necessarily right.

"This goes back to the origins of the Quincy and the Shinigami."

"To successfully save her life and maintain her human form, we need a soul that is completely opposite to that of a Quincy."

"And because this balance had to be maintained at all times, this force could not leave her until her death."

Yuko stroked her chin, pondering, "The power of the Grim Reaper..."

"Nonsense!" Ryūgen Ishida suddenly interrupted.

Everyone instinctively looked at him.

Ryūgen Ishida couldn't accept it: "There must be other ways..."

“You’re a smart person, you understand quickly. I know you can’t agree, but…”

"The choice is not yours."

Yuko pointed to herself, puzzled: "Should I do it?"

Kisuke Urahara almost stumbled and fell. He pulled down his hat brim and said embarrassedly, "Putting aside the fact that your soul has already reacted with the Hollow, Yuuko, the problem here is not something that can be solved simply by staying by her side."

"You are the one who has the choice."

"Shiba Isshin".

As Kisuke Urahara explained, he lifted the white cloth covering the props behind him.

"This artificial body is made from human souls and can completely envelop any soul that enters here in human form."

What came into view was a grotesque corpse, curled up and without facial features, just like a mannequin in a clothing store.

"The opposite of the Quincy is the Shinigami, and the opposite of the Hollows is humanity."

"In other words, once you enter this prosthetic body, you will become an existence somewhere between death and humanity."

"You should understand now, right?"

“However, this is a choice that does more harm than good for you.” Kisuke Urahara looked down at the artificial body. “While you are inside this artificial body, you probably won’t even be able to see a Hollow, let alone use the power of a Shinigami.”

"And once you're inside, you might never be able to recover."

Are the disadvantages greater than the advantages?

For Death, it's all disadvantages and no advantages whatsoever!

How could I possibly accept such conditions!

Ryugen Ishida lowered his head, already prepared to be rejected.

"Wait, why are you so well-prepared?" Yuko pointed at the artificial body on the ground, puzzled. "When was this artificial body prepared?"

Kisuke Urahara laughed and said, "That's called prevention."

"I understand! I'll do it!" Shiba Isshin interrupted the crowd's discussion.

Ryūgen Ishida looked at him in shock.

"If I were to stand by and watch my benefactor die, I would surely laugh at myself tomorrow!"

Ishida Ryūgen couldn't quite describe the feeling in his heart.

He naturally hoped that Shiba Ichishin would agree, but when he actually agreed, he felt a heavy blockage in his heart.

"I understand. Then come with me."

Kisuke Urahara took Isshin Shiba to perform the ceremony.

Yuko watched the two figures leave and was about to follow them.

"I'm counting on you guys for Masaki."

Ishida Ryūken left behind these words and turned away alone.

Yuko turned back and watched him leave.

"Tsk tsk, Kisuke, he really broke up a good couple."

Yoruichi suddenly appeared out of nowhere, shaking her head with amusement in her eyes.

Yuko asked doubtfully, "Couple? Really?"

"Huh? You can't even see that?" Yoruichi's eyelids drooped. "Wasn't that Quincy brat definitely interested in that girl?"

"If you can't even see this, you've wasted hundreds of years of your life."

Yuko stared at the doorway in silence for a moment before saying, "...No, that's not it."

"Ok?"

"I think he felt more guilty towards that girl."

"Guilty?"

"Ah."

“Perhaps there is love, but for him, guilt outweighs affection,” Yu Zi said calmly. “This might not be a bad thing for him.”

Although this is not a wedding ceremony, none of you here are idiots.

The kind of relationship that requires being together all the time is simply impossible if you're not a married couple.

The rest depends on what the girl thinks.

Yoruichi licked her paws, washed her face, and asked, "Do you think that girl would accept such an idiot?"

"Idiot?" Yu Zi raised an eyebrow. "In some ways, there's a market for that kind of idiot."

Yoruichi exclaimed incredulously, "Huh? Is your taste really okay?"

That kind of guy may look sunny and cheerful, but he's definitely not handsome at all.

He can't even compare to Byakuya Kuchiki, let alone Kisuke Urahara.

Yu Zi coldly replied, "Don't you think he looks like the main character?"

"What? What did you say?"

Yuko shook her head: "Among the Shinigami, there aren't many who can set aside their prejudices and treat Quincy without prejudice."

"Really? But I don't have any prejudice."

Yuko looked at her and said, "You have a prejudice against me."

A well-shaped character appeared on Yoruichi's forehead, revealing sharp claws that flashed with a cold light: "You'd better not sleep too soundly tonight, or I'll scratch a few big cat marks on your face."

Yuko completely ignored her threat: "Alright, I'm not going to argue with you anymore. I'm going to see what's going on with them..."

Before Yuko could finish speaking, Kisuke Urahara returned.

"it's over?"

"Huh? Is there a problem?"

"too fast!"

Kisuke Urahara covered his face with a fan: "Well, there's really nothing to see here. It's just about guiding him into that girl's inner world to deal with that monster."

"Isn't this still the same method used by Hirako and the others?"

“Of course it’s different.” Kisuke Urahara was somewhat speechless. “We didn’t have the help of Quincy back then.”

"Taking control of one's body through one's own power is not a complete solution; it is merely a temporary suppression and the conversion of the power of the void into one's own."

"As for Ms. Masaki, because of Shiba Isshin who is connected to her soul, she is no different from an ordinary person in normal times, and she can still use the Quincy's abilities at will."

Yoruichi licked her paws: "But that Shinigami has been completely reduced to an ordinary person, hasn't he?"

"Yes, that's true at least during the time that girl was alive."

"..."

A short while later, Shiba Isshin returned to the group wearing the Gikai.

At that moment, he was wearing a simple coat and looked like an ordinary young man.

Yuko's golden eyes swept over his body, and she could clearly see that the Gikai completely blocked the spiritual pressure within Shiba Isshin's body.

"Hey, how are you?" Kisuke Urahara asked with a smile, his face partially hidden by his paper fan. "Are you getting used to this body?"

Shiba Ichishin rotated his arm: "Ah, although it's a little uncomfortable, overall it's not a problem."

"Where is that girl?"

"Msaki is still fast asleep, but she's alright now." Shiba Isshin smiled slightly. "Thank you for your concern."

Yu Zi's lips twitched: "You're talking like an old married couple."

“…Ha, haha.” Shiba Isshin paused for a moment, then scratched his head sheepishly. “I still don’t know what Masaki-san thinks of me…”

They're just like a pair of silly lovers head over heels in love.

Yoruichi rolled her eyes and asked in a deep voice, "Are you from the Shiba family?"

"I never expected that the Shiba family could produce a decent captain."

Yuko asked curiously, "What do you mean by the Shiba family?"

Yoruichi slapped her face with her paw: "What exactly did you learn back then?"

"The Shiba family is the Shiba family that was once known as one of the four great noble families, along with Shihōin, Kuchiki, and Tsuna Yayoi."

Yuko asked, puzzled, "Then why haven't I heard of it?"

"Who knows!" Yoruichi replied irritably.

Kisuke Urahara watched this scene with a smile and explained, "The Shiba family declined a long time ago, and its members are now scattered throughout Rukongai. It's understandable that Ikuko wouldn't know."

Shiba Isshin smiled, not caring at all: "It's just a division of the family."

“The disappearance of the Shiba family’s captain in the mortal world is no small matter.” Yoruichi narrowed her eyes and looked at Yuuko. “Let’s keep things a little quiet for a while.”

That's true, but why are you only looking at me?

Yoruichi rolled her eyes: "Because you're the most restless one!"

They all seem to be good people...

Shiba Isshin watched this scene. He had thought that those who were expelled from Soul Society were all sinners, but now it seemed that there must be some unknown secret behind it.

Could it be related to that strange Hollow?

"Speaking of which, you are..." Shiba Isshin looked down at Yoruichi.

Yoruichi said calmly, "Yoruichi Shihouin."

"But I heard that Yoruichi Shihouin should be a woman, right?"

Yu Zi waved her hand and said nonsensically, "Don't worry about it. She injured her throat before, so her voice sounds like a man's."

"I see."

Yoruichi, her face dark, kicked out and lashed out with her tail at Yuko's face.

"You can't hit me!" Yu Zi leaned back slightly, dodging the attack.

Yoruichi smiled eerily: "Heh, you better remember this."

"..."

Yuko quickly changed the subject: "Um, young man, since we can't go back, have you thought about what you can do in the present world?"

Shiba was filled with confusion: "What should we do?"

“Do you know?” Yuko said seriously, “Money is essential to live in the modern world.”

"Money is indispensable if you want to date, get married, and have children."

"You're just a homeless person with nothing right now, be careful not to be looked down upon."

"Eek!!!" Shiba Isshin's eyes widened, and he asked anxiously, "What should I do?"

"It's okay, I'll teach you how to make big money."

Yoruichi jumped onto her shoulder in an annoyed tone and smacked her with her paw: "The ways you talked about making money don't work anymore!"

"Tsk, don't say it out loud, I'm planning to find a scapegoat to take my place in jail."

Shiba Isshin: Please don't say that in front of him!

"Don't worry, Mr. Isshin." Kisuke Urahara squinted. "The shop still has some savings, enough to help you survive in the real world."

Shiba was deeply moved and said, "I am extremely grateful!"

Yu Zi held out her hand: "Are you very rich? How about I lend you tens of millions to see your strength?"

"I was actually planning to open a clinic, and I just happened to be short of an investor."

"Is it just a lack of investors?" Yoruichi retorted. "I feel like you're lacking everything."

"It's no problem! It's just a medical license, easy peasy!"

"A doctor?"

These words gave Shiba Isshin a direction.

He's currently imprisoned in a fake body, unable to use the power of the Grim Reaper, and lacks understanding of the real world, so how he'll survive is a problem.

However, the medical skills he learned at the True Spiritual Arts Academy were genuine.

If we could open a clinic, we could give Ms. Masaki a warm home, right?
