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

Chapter 555's real name is - Butterfly

Yuko smiled and said, "I feel like she's even more amazing than Yoruichi."

As expected, Soi Fon blushed and waved her hand hastily: "No, no, that's not true. I'm still far behind Yoruichi-sama."

"One, it's not impressive at all."

"Don't underestimate yourself. To be able to unleash your Zanpakuto at such a young age, what else could you be but a genius?"

"I will need your guidance from Soi Fon-sensei from now on."

"But, but Yuko is much more capable than me, I don't know what to do."

"No, that's not true. I only managed to fight Soi Fon because of some special reasons. In fact, I was only in a light-handed stance with my Zanpakuto." Yuko said, patting the Zanpakuto at her waist.

Soi Fon covered her mouth, looking surprised: "Asauchi? How could this be..."

She had just heard Yoruichi talk about the techniques for releasing Zanpakuto, and thought he was just joking. She didn't expect that Yuuko-neechan hadn't even released her Zanpakuto.

Yuko squatted down, a gentle smile on her face: "That's it. I'll leave the rest to Soi Fon-sensei."

"I, I will definitely try my best!" Yuko's words made Soi Fon feel flattered, and she stood there blushing, at a loss for words.

Soi Fon paused to calm herself down and asked, "Yoru, how does Lord Yoru usually train with Ikuko-neechan?"

Yuko honestly replied, "Usually, it's through actual combat."

"Yoruichi said that training through actual combat is the best way to increase spiritual pressure."

Soi Fon nodded slightly: "Indeed."

"However, to unleash your Zanpakuto, you must communicate with it. You must let it tell you its true name before it will fight alongside you."

"Then how can we communicate with it?"

“Hmm…” Soi Fon pondered for a moment, “Generally, it is done through the form of sword meditation. You place your Zanpakuto on your lap and immerse yourself in a meditative posture, then synchronize your thoughts with the Zanpakuto and enter your inner world. Naturally, you can then communicate with the Zanpakuto.”

Ikuko: "..."

It sounds very mysterious.

She doesn't understand at all!

After a while, Yuko gave up struggling: "In any case, let's start training with spiritual pressure first."

At least she could see the increase in spiritual pressure.

As for that Zanpakuto, let's wait until it's in a good mood and takes the initiative to communicate with her.

Yuko picked up a wooden sword from the sword rack in the dojo. "Then Soi Fon can fight me according to her usual training. If we only use spiritual pressure, I still have a lot to learn."

"Okay, I understand." Soi Fon walked towards the sword rack.

"For Soi Fon, just use your own Zanpakuto."

"Eh? But..."

"It's alright, I don't feel much pressure with a wooden sword." Although it's similar with a real sword, at least you'll feel injured if you get hit by one.

“Then let’s use your Zanpakuto, Yuuko-neechan,” Soi Fon said, not refusing Yuuko’s offer. “Fighting with it might make it easier to communicate with it.”

After hearing what Soi Fon said, Ikuko realized that there was some truth to it.

So the two decided to have a real fight.

"Sting and kill all enemies! Birds and wasps!"

After the release command, the Zanpakuto, which resembled a samurai sword, instantly transformed into a sharp fingertip and was placed on Soi Fon's finger.

Yuko finds this scene magical every time she sees it.

If only her Zanpakuto could become a cosmic superhero, then she could just smash all her enemies into the ground without doing anything.

Hmm, it's said that Zanpakuto are highly compatible with their master's soul, maybe that's true.

Yuko drew her Asauchi from her waist as a sign of respect. The Asauchi was completely different in appearance and length from the Nichirin Blade that Yuko had used before, and it also felt very different.

But Yu Zi had, after all, opened the channel realm and reached the highest realm of martial arts. It was just a little inconvenient, and she could get used to it after a while.

"I'm here," Soi Fon warned, then vanished from her spot in an instant, attacking Yuuko.

Unfortunately, nothing can escape Yuko's eyes.

Of course, that was just a joke. In fact, Yuko had already turned off her clear vision and was only relying on her physical constitution to react to Soi Fon's speed and strength.

After a few rounds, Yuko suddenly realized that she seemed to be giving Soi Fon special training.

Even without using her demonic powers, Soi Fon couldn't overpower Yuuko in a fight based solely on her physical abilities, even with her spiritual pressure. Soi Fon isn't Yoruichi; she's still too young, her physique hasn't fully matured, and her spiritual pressure level is only slightly higher than Yuuko's, still considerably weaker than some of the seated officials.

Hmm? The official in charge of the banquet?

So, Soi Fon really is talented.

Yuko had only meant to amuse the child, but then she suddenly realized...

Wait, does that mean her abilities are comparable to the vice-captain's?

Hmm, it's a pity there's no good reference point.

Since that's the case, let's think about the release phrase for our Zanpakuto.

After forcing Soi Fon back with a single blow, Ikuko raised her hand to strike.

"Bloom, Blood Rose."

Soi Fon's expression turned serious, and she tensed up a bit.

however……

swoosh~

A cold wind blew by...

"Uh." Yuko stood there awkwardly. "It seems that's not her name."

Soi Fon nearly collapsed, unable to resist complaining, "What do you take the true name of your Zanpakuto for?"

"Uh, a response from the soul?"

"..."

Theoretically speaking, this seems to make some sense.

Zanpakuto is half of a Shinigami, essentially the other side of a Shinigami, and can be said to be the one that understands Shinigami the most.

Conversely, Shinigami should also be the ones who understand their Zanpakuto best.

“If it’s not called Blood Rose, what else do I like?” Yuko raised her Zanpakuto, the tip pointing directly at the roof.

"Overwhelmingly, isn't it? Money and jewels?"

"Uh, isn't that wrong too?"

That would be absurd!

Soi Fon was disheveled in the wind. So, what exactly do you take your Zanpakuto for?

Can you please stop insulting people with such superficial things?

If she were a Zanpakuto, she would rather die than respond to you.

"Then, the twelfth form of Snow Breathing?"

What is that?

Why am I suddenly reciting something that sounds like a move name again?

Soi Fon is completely numb.

"Uh, a butterfly?" Yu Zi muttered as if possessed.

Boom~

Suddenly, a beam of blue-purple light burst forth from the Zanpakuto, blooming like a light cannon, rapidly rising and bursting forth from the tip of the blade, piercing straight through the roof.

Yuko's spiritual pressure began to rise rapidly. If described in terms of levels, her spiritual pressure level was probably still above level ten just now, but it had already reached level four or five, and this spiritual pressure was still rising.

At the same time, the Shinigami within Seireitei seemed to feel the soaring spiritual pressure and all looked towards the direction of the beam of light.

Even though Yoruichi was already far from home thanks to her highly mobile Shunpo, she could still feel the spiritual pressure emanating from afar and couldn't help but turn around to look.

"Tsk, this spiritual pressure level, is it Bankai?" Yoruichi's eyes held a hint of amusement. "To dare to use Bankai in Seireitei, that's really interesting."

She could already picture the old man Yamamoto in a rage...

Wait, why does this spiritual pressure feel strangely familiar?

Ye Yi's expression changed slightly, and an annoying face involuntarily surfaced in his mind.

It's a lie...

……

Wooden debris kept falling from the roof. Yuko finally came to her senses and, somewhat flustered, raised her Zanpakuto and asked Soi Fon a question.

How do I stop it?

Soi Fon was completely dumbfounded.

She never imagined that someone would actually guess the true name of her Zanpakuto.

No? It can be like this?

Yuko's rapidly rising spiritual pressure gradually affected Soi Fon. Even though the powerful spiritual pressure wasn't directed at her, it made her feel as if she were being crushed by heavy stones, making it difficult to breathe.

The spiritual pressure was at the vice-captain level; at least, she had never felt this level of suppression from Vice-Captain Ōmaeda.

Upon hearing Yuuko's words, Soi Fon quickly withstood the spiritual pressure and shouted at her, "Call it, call its true name, control it with your will."

"Didn't I already read it out loud?" Yuko shouted, and then began to mutter.

"Stop, stop for a moment."

"Stop, butterfly."

"Stop right there, Sister Butterfly!"

After a while of struggling, it was unclear whether the Zanpakuto had actually heard her, but it eventually stopped.

The purplish-blue beam of light gradually receded from the rooftop, turning into tiny particles of spiritual energy that disappeared.

Yuko looked up at the large hole in the ceiling and wiped the cold sweat that was spreading down her forehead.

"No, it's nothing. I just made some money from Yoruichi at noon. It's just a roof, it should be enough to mend it."

"You...you're right, aren't you, Soi Fon?"

Soi Fon stood there woodenly.

"Answer me, Soi Fon! Everything should be alright, right?! This house wasn't made of anything expensive, so it shouldn't be a serious problem, right?"

Before Soi Fon could respond, a deep, weathered male voice suddenly rang out from the side.

"My beautiful lady, I think the problem is a bit serious."

Yuko paused for a moment, then turned around in surprise to see a middle-aged man with a stubble beard, wearing a flashy pink haori, looking up at the large hole blasted out by spiritual pressure with great interest.

"How serious is it? Can you pay it off by doing part-time jobs for several years?"

“I think the problem is much more serious than that.”

"Looks like I can't stay here anymore, I can't afford to pay for this." Yu Zi muttered to herself, then sighed and looked at the middle-aged man. "That sleazy old man, do you think I still have a chance to escape now?"

"Sexy, flamboyant old man..." Kyoraku Shunsui almost fainted, his lips twitching slightly. "I don't think it'll work~"

"Unauthorized Bankai release within Seireitei is a violation of the squad's orders."

"Bankai? Was that Bankai just now? I was just saying it for fun."

"..."

How could someone possibly make up such a story? But he really couldn't tell that the other person was lying. It was strange.

Of course, more importantly, a Shinigami with this level of spiritual pressure shouldn't have people he doesn't know.

Kyoraku Shunsui looked around the dojo: "Speaking of which, where's Captain Yoruichi? Did you kill her already?"

“Cough cough…” Yu Zi coughed twice. “I’m just a thief who came to steal from a noble family. I don’t know any Captain Yoruichi.”

Oh no, oh no, I'm going to cause Yoruichi a lot of trouble.

"You bastard! What have you done now!" A furious voice leaped down from the hole in the roof, landing in front of Yuko and cracking the floorboards at her feet.

Yu Ziqing involuntarily took two steps back: "Who, who are you?!"

"You think you can just turn your back on me after doing something bad?" Yoruichi, her eyes bloodshot, stepped forward, grabbed Yuko, and shoved her face against Yuko's, forehead to forehead. "You despicable woman!"

"Now see who I am!"

"answer me!"

Yoruichi's saliva was practically smearing Ikuko's face.

Yu Zi hesitated for a moment before speaking, "Yes, there are outsiders."

"Don't even mention outsiders, even if old man Yamamoto were standing here, he couldn't protect you now!" Yoruichi grabbed Yoruichi's collar with both hands and shook her violently back and forth, as if trying to shake Yuuko's brains evenly.

"That's really great! I've only just left my house and you've already caused such a big problem for me."

Yu Zi replied with a forced smile, "What could I do? I just tried calling its name, and who knew it would suddenly react on its own."

"If you don't believe me, ask Soi Fon."

"Huh? Why the change in appearance?" Yuko picked up her Zanpakuto and realized that Asauchi's posture had changed.

Originally just an ordinary samurai sword, it now resembles her modified Shura sword, lacking a tsuba (handguard) and featuring only a smooth, slender blade.

The handle is entirely black, wrapped with white ribbons, while the blade has a beautiful color, mainly purple-blue. It doesn't look too bright, but rather very bright, and can even reflect the surrounding scenery. The words "Destroy Evil Demons" are engraved on the blade near the handle.

Yoruichi was momentarily stunned by the dazzling Zanpakuto.

"Ahem." At this moment, Kyoraku Shunsui couldn't help but cough twice.

"Captain Kyoraku." Yoruichi then noticed that the captain had already arrived.

She was so angry just now that she didn't even notice.

Kyoraku Shunsui shrugged: "Since Captain Yoruichi knows this beautiful lady, things will be much easier."

Yoruichi's face darkened, and she turned to look at Yuuko.

Yu Zi muttered under her breath, "I already told you I don't know you, see? You've been found out."

Yoruichi glared at him fiercely, then turned to Kyoraku Shunsui with a beaming smile: "What a rare guest, Kyoraku-sensei! What brings you here today?"

"Would you like a cup of tea first?"

Kyoraku Shunsui remained unmoved: "No need, you should come with me to see old man Yamamoto first."

Yoruichi wanted to say something more, but Ikuko stepped forward and patted her on the shoulder.

"This pink-clad uncle is even more shameless than me, and he doesn't know how to be flexible. I don't think we can reason with him."

"Yoruichi, you might as well hand me over. I don't want to be a burden to you."

Yuko was genuinely feeling a little guilty.

Who knows how this release of the Zanpakuto became known everywhere, like setting off fireworks?

They were originally hiding in Ye's house, but now the whole world knows.

Yoruichi was speechless: "What do you mean, 'hand you over'? It's like I'm keeping you as a mistress."

"No, that's not how you use that word." Kyoraku Shunsui broke out in a cold sweat. Why does it feel like none of you are normal?
