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

Chapter 669 Nighttime Infiltration

Yu Zi rolled her eyes and shrugged: "What else? Just one night... no, just two hours of last-minute cramming, and you've already done pretty well. You think you can take down the captain? Isn't that a bit too arrogant?"

"Which of the captains of the Gotei 13 hasn't cultivated for decades or even centuries? If they could be killed by a fake Shinigami like you who only started halfway through their careers and has been a Shinigami for a few months, then they might as well not be captains, they should just be called chickens."

Ichigo's lips twitched violently. Although Aunt Yuko looked nostalgic in this state, she was still incredibly annoying.

Yoruichi jumped down the corridor and walked gracefully to Yuuko's side, saying calmly, "His growth rate is indeed astonishing. In just one night of guidance, his control over spiritual power has made a qualitative leap."

At this point, Yoruichi couldn't help but look up at Yuuko: "You have a sharp tongue, but you're really good at teaching people."

“Of course, after all, I’m a professional.” Yuko looked away, her face full of self-righteousness. “If I hadn’t changed careers back then, Karakura Town’s college entrance rate would be at least ten percentage points lower now.”

You've really blown your tongue, Auntie.

Ichigo's eyes twitched as he listened, and he simply collapsed to the ground, panting heavily, sweat dripping from his orange hair and soaking the soil beneath his feet.

He felt like all the bones in his body were about to fall apart, but the surging spiritual energy within him was more exhilarating than ever before.

It was so exhilarating that it brought back memories of fighting alongside Chad in high school, taking on an entire gang single-handedly.

Yoruichi said speechlessly, "But looking like this, will he be able to make it in time for tonight's operation?"

This is going too far. Will they have time to recover before tonight?

Ichigo was about to wave his hand when Yuko spoke first: "I think it's fine. I always see him getting beaten up, he'll recover quickly."

Ichigo: "..."

Am I even human?! Am I even human?!

The noise in the courtyard was contained by Yuko's barrier and did not affect anyone. Even the weeds and the ground in the courtyard were not damaged in the slightest. They were exactly the same as yesterday, which greatly shocked Ichigo.

When Inoue Orihime, Ishida Uryu, and the others woke up in the early morning, they did not find anything unusual.

Horiuchi and Shibata prepared a simple breakfast for everyone; although it was just some coarse rice porridge, their good intentions were evident.

Inoue Orihime entered the three's room and called out, "Everyone, Kurosaki-san, it's time for breakfast."

Seeing the scene before her, Orihime paused for a moment, then asked, "Huh? What are you all doing?"

Chad squatted down in front of Ichigo and turned around to say, "I haven't been able to wake him up since just now."

Yuko, who was passing by, glanced inside and said indifferently, "Is that the one? He's dead."

"Huh?!?!" Inoue Orihime exclaimed in shock, "Why?"

"Legend has it that every night in the Soul Society, a monster roams around and randomly breaks into people's homes to devour the souls inside."

"Oh, how scary!" Orihime covered her mouth and involuntarily took two steps back. "That Kurosaki-san..."

Yu Zi nodded silently: "Yes, they've probably already met their demise."

Chad, Ishida: ...Are you kidding me?!

"How could this be..." Orihime rushed into the room with tears in her eyes, yanked Ichigo up from the floor, and shook him violently. "Kurosaki-kun! Don't die! I'll heal you right away..."

"What happened? What happened? An earthquake?"

Kurosaki Ichigo regained consciousness from the violent shaking and stared blankly at Inoue Orihime, who was crying her eyes out.

Inoue Orihime hugged him tightly, overwhelmed with emotion, "Thank goodness! Kurosaki-kun is back to life!"

Yuko froze for two seconds.

Would you say she helped him out?

……

I'm sorry, Ryuki, Rukia, she is guilty.

……

At the dinner table, Yuko, her hair disheveled, looked down and said, "I'm so sorry, I shouldn't have made that kind of joke."

Beside her stood Yoruichi, who had retracted her claws with a speechless expression.

Ichigo looked at Yoruichi with some surprise. Wow, she's amazing. She can actually make Aunt Yuuko so obedient.

What is the relationship between these two people?

He had wanted to ask this for a long time: Yoruichi-san seemed to like to perch on his aunt's head most of the time, and most importantly, his aunt never blamed him.

This doesn't seem like a pet-owner relationship at all!

Besides, what pet is this amazing?

Are they boyfriend and girlfriend?

Ichigo was shocked.

Orihime Inoue quickly waved her hand: "No, it's alright."

She found some strange dried fruit peels from somewhere and suggested excitedly, "By the way! I just saw some things that look like fruit peels outside. Should we try putting them in the porridge?"

Ichigo's face instantly turned green: "Spare me..."

Wouldn't it be poisonous?

Yu Zi picked up a piece with great interest, put it in her mouth and chewed it, then commented: "It feels like an old lady's foot binding cloth, smelly and hard."

Ichigo retorted, "Putting aside the nonsense of your analogy, how can you eat this with such a straight face?!"

"It's alright, I don't feel guilty about eating it."

"Guilt...guilt?" Ichigo's hand trembled. "What did you eat before?"

"What? Of course it's human flesh. Of course, I don't usually eat the flesh of you grown men. I prefer to eat the flesh of children."

That sounds even more dangerous!

Yoruichi jumped up and smacked her on the head: "You'd better eat your food properly!"

"..."

After everyone had breakfast, Ichigo went back to his room to rest and replenish his strength and energy.

Ishida and the others learned about the local customs and culture of Rukongai in the vicinity.

The Seireitei seemed completely unconcerned about their intrusion; despite being hidden in a corner just across the street, no Grim Reapers searched for them.

Yoruichi only told them not to go too far.

"Are you really going to join the Fourth Division?"

Inside the room, Yoruichi licked her paws, her tone tinged with uncertainty, "That woman Unohana is hard to say. A hundred years have passed, who knows which side she's on now."

"Don't worry." Yuko was sitting next to him, wiping the blade of his Zanpakuto with a cloth. "Hana-nee doesn't have any feelings for Seireitei. She's just keeping her promise."

Yoruichi looked at Ikuko with surprise: "Keep the promise?"

Yu Zi smirked: "You didn't know? Looks like you've been excluded from Sister Hua's social circle."

Ye's face darkened: "Who wants to get into that woman's social circle? Are you going to tell me or not?"

Yuko said calmly, "She only lost to Yamamoto and was invited by him to join the Gotei 13."

"……I see."

This certainly explains why, given that woman's personality, she would be willing to live in a secluded corner.

"Of course, the main problem is that she's been badmouthing me to everyone." Yuko raised her Zanpakuto, seemingly eager to kill Unohana Retsu. "How could I not get my revenge..."

Before she could finish speaking, she was hit on the head again.

Yoruichi's eyelids drooped, her golden eyes filled with speechlessness: "Give me a break and be normal."

Time passed quickly, and evening arrived. Ichigo, who had slept all day, stretched and walked out of his room.

He yawned and asked Yuuko and Yoruichi outside, "Where is everyone?"

"is back."

No sooner had Yuko finished speaking than Inoue Orihime darted out from the side.

"Kurosaki-kun! You're awake!"

"Ah, oh..."

Yoruichi jumped onto Yuuko's head, looked at everyone, and said, "It's almost time. Are you all ready?"

The playful expressions on everyone's faces subsided somewhat, and they nodded seriously.

"Ah."

Yoruichi instructed, "Remember, don't do anything unnecessary. You just need to stand together holding hands."

Everyone nodded: "Understood."

"Well then, just in case, I'll give you this in advance." Yu Zi made a grabbing motion in the air, and several glass bottles filled with red potion appeared in her hand, which she casually tossed to the crowd.

Ichigo instinctively took it and asked curiously, "What's this?"

"A special medicine, used when the injury is too severe," Yu Zi said calmly. "It can also cure common toxins."

"Internal medication for internal injuries, topical application for external injuries. That should be easy to understand, right?"

Kurosaki Ichigo put away the medicine bottle and gave Ikuko a thumbs up: "As expected of a veteran doctor."

Yuko rolled her eyes.

Gradually, the last ray of sunlight disappeared below the horizon, and night fell completely.

After everyone gathered in the courtyard and said goodbye to Horiuchi and Shibata, Ikuko told them to leave the scene to avoid being stunned by the spiritual pressure leaked from the Bankai.

Holding her Zanpakuto, Yuuko turned to the group and asked, "Are you ready?"

"no problem."

Led by Ichigo Kurosaki and Uryu Ishida, the two put their arms around Ikuko's shoulders, while Orihime Inoue and Chad held onto Ichigo Kurosaki and Uryu Ishida respectively.

"Then, let's go."

Yoruichi, who was perched on Yuuko's head, said this.

Yuko slowly raised her right hand, the dark purple Zanpakuto emitting a hazy purple light in the night. She took a deep breath, and her golden eyes, driven by spiritual pressure, transformed back into double pupils, their eyes gleaming with a deep, mysterious light.

He whispered, "Bankai: Shinra Disorder".

In an instant, an indescribable spiritual pressure spread out from her center, invisible and silent.

Yoruichi narrowed her eyes. The name wasn't complete. Was it an incomplete Bankai?

Yuko, you really are a genius.

The next moment, everyone felt their bodies becoming lighter, and a strange peeling sensation came from the ground beneath their feet.

Ichigo stared in shock, his eyes wide: "This, this is..."

Before he finished speaking, he was lifted off the ground, his body rising slowly and involuntarily, and soon he flew into the sky.

"Wow~ I'm flying~" Orihime Inoue instinctively opened her arms wide...

"Hey idiot!" Ichigo was startled when he realized the hand on his shoulder had suddenly disappeared. He turned around to grab it, only to find that Orihime was still floating behind him and had not fallen behind.

"Oh, sorry." Orihime Inoue realized what was happening and quickly grabbed Ichigo.

Everyone: "..."

"Don't worry, it's just in case you don't understand human language, that's why I told you to hold on tight," Yu Zi said calmly.

Within the area affected by her Bankai, everyone is currently in a state of weightlessness.

They moved faster and faster, and the streetscape of Rukongai shrank rapidly beneath their feet, soon becoming blurred in the night.

Yuko led everyone to the top of Seireitei: "If we go down the ground, we will trigger the defensive spells directly, and the walls of Soul Society will be erected. So, we will go in from above."

Yoruichi explained, "The Seireitei is surrounded by the Seireitei Wall, which is constructed from Killing Stones that can block spiritual energy. These Killing Stones release fluctuations that decompose spiritual energy, creating a circular protective shield called the Soul-Shielding Membrane, used to defend against any intruders approaching from above."

As they drew closer, a translucent membrane, visible to the naked eye and rippling gently like water, appeared beneath their feet.

Ishida Uryu asked, "Then how do we break through the Soul-Shielding Membrane?"

"Just keep an eye on it." Yoruichi patted Yuuko's head. "You can descend now."

"Ah."

Yuko responded and led everyone down slowly. Seireitei was still peaceful and serene. The patrol team was chatting and laughing. No one could have imagined that at this moment, in the middle of the night, an enemy would invade the skies above Seireitei.

Just as she was about to land on the Soul-Shielding Membrane, a wisp of spiritual energy flashed in Yuko's eyes. She swung her Zanpakuto and slashed directly at the Soul-Shielding Membrane.

"A Dance Against All Reason: Disaster Relief!"

The protective membrane was torn open like a plastic sheet, allowing everyone to enter the high-altitude interior of Seireitei.

"You... you just got in like that?"

Everyone couldn't help but feel relieved.

Yu Zi hesitated and turned back: "Then how about we go back and start over? Make a big fuss?"

Everyone quickly shook their heads: "No, no, no!"

Yoruichi rolled her eyes speechlessly. This guy was really something, still playing tricks on people even at a time like this.

Ultimately, the Soul-Shielding Membrane is also composed of spiritual energy, and it can be neutralized by using spiritual particles of equal mass.

Of course, this requires an enormous amount of spiritual pressure.

Compared to neutralizing the spiritual power of the Soul-Binding Membrane, it would be much simpler to break through it directly.

However, Yuko can use her abilities to fulfill the conditions for offsetting the situation.

If it weren't for the fact that Shikai might be more troublesome and leak more spiritual energy, she wouldn't need to use Bankai at all.

"Hey, Auntie, isn't that the Penitentiary Palace where Rukia is imprisoned?" In mid-air, Ichigo patted Yuuko on the shoulder and pointed to the white tower in the distance.

“Well, we don’t know if Rukia is really there, so we can’t go there rashly.” Yuko glanced sideways.

Yoruichi continued, "Moreover, the Shinigami have already been alerted."

Only then did everyone notice that the peaceful atmosphere in Seireitei had suddenly become tense.

Yuko's Bankai didn't allow them to enter silently; the Soul-Shielding Membrane had a tear, so it was quickly noticed. However, thanks to the darkness and the concealment of the Bankai, they hadn't been discovered yet.

The Seireitei is now on high alert.

Yuko controlled the gravity within the domain, allowing everyone to descend smoothly and swiftly towards a certain area of ​​Seireitei.

When their feet touched solid ground again, everyone was still a little unsteady, while Yuko had already sheathed her Zanpakuto.

They landed in an elegant courtyard, where the air was filled with a faint fragrance of herbs, and the surrounding buildings were simple and tranquil.

"This is..." Ichigo looked around and lowered his voice.

Yoruichi said in a deep voice, "The Fourth Division barracks."
