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

Yoruichi put one hand on her hip and tapped Yuuko's forehead hard with the other, forcing her to back away: "What do you think the Nest of Maggots is?"

Do you think you can just come in whenever you want?

Who do you think you are?

"Ah? Answer me!"

"Who are you?!"

Yu Zi quickly defended herself, saying, "Stop, stop, stop! I know I was wrong!"

The two laughed and playfully wrestled together.

……

The next day, at the First Squad barracks.

"excuse me."

Yoruichi pushed open the door to Yamamoto Genryusai Shigekuni's office, and Ikuko followed closely behind, peeking out from behind her to survey the situation inside.

Yamamoto Genryusai Shigekuni was sitting behind his desk, holding a brush in his hand, reviewing documents.

Meanwhile, Chojiro Sasakibe waited solemnly to the side.

"It must be tough, Vice Captain. The Captain is handling official business, and you have to stay by his side." Yuko whispered in Yoruichi's ear in a voice only the two of them could hear.

Yoruichi didn't turn around, but gently nudged her with her elbow, signaling her to stop fooling around.

"Captain-Commander." Yoruichi put away her usual playful smile and bowed respectfully.

"Sorry to bother you." Yu Zi nodded slightly, mimicking her gesture.

"What is it?" Yamamoto Genryusai slowly raised his head. Although his eyes showed signs of age, they were as sharp as an eagle's, as if they could see through people's hearts.

His gaze lingered briefly on Yoruichi before settling on Ikuko behind her.

Night got straight to the point: "Captain-Commander Yamamoto, I intend to appoint Ikuko Tsugikuni, the Third Seat of the Second Division, as the supervisor of the Maggot Nest. I have come here to request your permission."

Chojiro looked at them with some surprise.

A nest of maggots?

I see. If it is this person, then the captain's permission is indeed required.

The Maggot's Nest serves as a place to imprison potentially dangerous individuals. Although the people imprisoned there are not as powerful as those in the Underworld, if they are not trustworthy, they could still cause great trouble.

It's no wonder that even though it was originally under the jurisdiction of the Second Division, it still had to seek the Captain-Commander's approval.

Yamamoto Genryusai Shigekuni did not answer immediately, but instead looked deeply into Ikuko with his aged yet sharp eyes.

"Kuni Ikuko." After a long pause, he spoke in a deep voice, not loud, but carrying an undeniable authority, "Do you know where the maggot's nest is?"

Yuko replied, "I heard Yoruichi mention it; it's a prison for dangerous individuals."

Yoruichi's lips twitched: "I think I was referring to something that might pose a danger to Soul Society, right?"

Yuko asked疑惑地问道, "Is there a difference?"

"Nonsense!" Yoruichi rolled her eyes. "One is already a criminal, and the other isn't."

"Why are criminals imprisoned?"

"Because he poses a potential danger."

Yu Zi asked curiously, "Then how do we determine if he poses a potential danger? Is it his strength? His personality? Or something else?"

Yoruichi was getting a little frustrated: "Why do you ask so many questions?"

Yuko opened her mouth, as if she wanted to say something more...

Boom!

Suddenly, a chilling thud came from the side.

The two instinctively turned their heads to look, only to see Yamamoto Genryusai Shigekuni slamming his cane down heavily, causing the floor to crack from the impact.

“…” After staring at the cracked floor for two seconds, Yuko turned her head and continued to ask, “Isn’t it a bit unreasonable to detain someone if they haven’t committed a crime?”

Yoruichi is about to break down. Can't you see the situation, you idiot?

boom! ! !

boom! ! !

The floor cracked again from the impact of the cane, and a powerful spiritual pressure swept over, as if the objects in the room were about to be torn apart by this powerful aura. Yuko's heart sank.

A bead of cold sweat trickled down Yoruichi's forehead. She should have just let Yuko come by herself; she was asking for trouble by bringing her along.

"Tsugikuni Ikuko!" Yamamoto Genryusai Shigekuni frowned and called out in a deep voice.

Yuko blinked: "I'm here."

Yamamoto Genryusai Shigekuni stared intently at her, amazed that she could remain so calm and composed under his spiritual pressure.

That is...

Is this guy already a captain-level player?

Yamamoto Genryusai Shigekuni slightly raised his eyes and said in a deep voice, "What qualifications do you think you have to be the guardian of the maggot's nest?"

“Urahara Kisuke must have been the third seat before, right? I’m the third seat now…” Yuko paused for a moment, then smiled helplessly, “Actually, I don’t really know what to say. In short, it depends on whether you, sir, will give me face.”

She is, after all, an outsider. Suddenly assigning her this kind of mission could lead to trouble if she turns out to be an undercover spy or something and releases the people from the Maggot Nest. That would keep Seireitei busy.

Ye Yi slapped her on the back: "You still expect the mountain... the captain to give you face? Why don't you just fly to the sky?!"

Yu Zi remained unmoved: "The problem is, didn't we come here precisely to get the Captain to give us face?"

Ye said expressionlessly, "Please remove the word 'they'."

Chojiro Sasaki's expression was a half-smile, and he was holding it in quite a bit.

What an unexpected person! How long has it been since Seireitei has seen such an interesting fellow?

Yamamoto Genryusai Shigekuni's gaze swept back and forth between the two men: "Whose idea was this?"

Yoruichi reluctantly raised her hand: "It's me."

Why did you choose her?

"Because after Urahara left the Second Division, the supervisory team responsible for guarding the maggot's nest was without a captain. Although Kikujiro is a seat officer, his unarmed combat ability is not outstanding. He is just filling in temporarily. The others also have their own arrangements." Yoruichi explained seriously.

“With Yuko’s unarmed combat skills, she can effectively suppress the prisoners in the maggot’s nest.”

Yamamoto Genryusai Shigekuni stared intently at her. Of course, that wasn't what he was asking. As a captain-level officer, it was no surprise that he was responsible for guarding the maggot's nest.

He knew that Yuko had become the captain of the Second Division. Although captains and vice-captains could be appointed directly by the captains of each division, as the captain-commander, he naturally had the right to know.

Yuuko is a special case. Before Yuuko became a seated official, Yoruichi had already submitted a report and was approved by him before she could become the third seated official.

What Yamamoto Genryusai Shigekuni wanted to ask was naturally...

Yoruichi covered her face and honestly replied, "Okay, since there haven't been any missions lately, this idiot has been rolling around at home all day. I couldn't stand it anymore, so I wanted to send her away."

"What?!" Yuko's eyes widened, one hand grabbing Yoruichi's clothes, her face full of disbelief.

How could you be such a person?!

Ye Yi, expressionless, pulled her aside and looked intently at the captain.

"...You must remember, as her introducer and guarantor, if anything happens to her, you will bear full responsibility." Yamamoto Genryusai Shigekuni gave Yoruichi a deep look.

"Yes! I vouch for it in the name of the Shihouin family." Yoruichi's face lit up with joy, and she agreed without hesitation.

"Go ahead." Yamamoto Genryusai Shigekuni waved his hand casually.

"Thanks~" Yuko waved with a smile and was dragged away by Yoruichi.

As Yoruichi walked out of the First Squad's barracks, he let out a long sigh of relief.

Yuko muttered, "I feel like the First Division must change their furniture all the time."

Before Yoruichi could even catch her breath, she couldn't help but punch Ikuko on the shoulder: "You bastard, can you please be serious when you're talking about important matters in the future?!"

"Aren't you afraid the old man will slap you against the wall?"

"Then I'll definitely fight back."

Yoruichi instantly went berserk: "Is this the problem?!"

“Just telling the truth.” Yu Zi shrugged. “Besides, the old man wasn’t angry at all. I looked at him, and his breathing and heartbeat were perfectly normal.”

"...You've got guts."

"Are you kidding? I'm the toughest guy around here, okay?!"

Yoruichi remained silent, glancing at the shoulder where Yoruichi had just been punched: "Tell me, can't you feel any pain?"

Although she didn't use her full strength in those two punches, they weren't just casual blows either, yet there was absolutely no reaction.

"Huh? It seems like he was beaten unconscious." Yu Zi paused for a moment, then her shoulders suddenly slumped.

Yoruichi's lips twitched: "I admit defeat."

Yu Zi smiled and explained, "Actually, you can still feel the pain, but because the recovery is so fast, you just have to endure that moment."

"Tsk." Yoruichi rolled her eyes at her unhappily. "Let's go. It's still early. I'll take you to see the Maggot Nest."

The two chatted as they walked toward the maggot's nest.

The maggot's nest is located inside the moat northwest of the Second Division barracks, covering an area roughly the size of thirty houses.

The prison is located in a mountainside, with only one entrance and exit, guarded by members of the Covert Force.

"Captain Yoruichi." Upon seeing Yoruichi, the guards all stepped forward to greet her respectfully.

Yoruichi waved her hand and pointed at Yuuko: "Get to know his face. This guy will be your boss from now on, the captain of the supervision team."

The two guards exchanged a glance and respectfully greeted Yu Zi, "Captain!"

Yu Zi nodded slightly in response.

"Let's go, it's just down here." Yoruichi didn't linger and led Ikuko into the cave.

Since the two of them had left their Zanpakuto at home before setting off to find the Captain-Commander, they went straight down.

The two entered the cave one after the other. Yu Zi peered inside and discovered that the mountain contained a vast world, with a staircase leading downwards in front of her.

The surrounding area consists of rough rock walls, and the mountain is crooked and uneven, resembling a primitive cave that has not been polished or developed much. Water droplets are dripping from above, and a cold and damp atmosphere can be faintly felt from below.

Yuko looked around and gave a simple assessment: "The environment isn't very good. I feel like I'd rather stay at home."

Yoruichi, who was leading the way, paused and turned back slowly: "Now that things have come to this, it's too late even if you want to regret it."

What do you mean by "it's better to stay at home"?

Who's the jerk making all this noise at home?!

"Ahem." Yu Zi coughed lightly. "It was just something I said casually."

The two walked up the steps one after the other, and could already see the gate below.

Yuko suddenly asked, "By the way, you haven't answered my question from before."

How do we determine if they are potential dangers?

Yoruichi paused for a moment, then resumed walking downwards, but soon she noticed something, turned around, and looked speechlessly at Ikuko, who was making a defensive move.

"What are you doing?"

Yu Zi gave an awkward smile: "I thought you stopped because you wanted to beat me up."

Yoruichi gave her a listless glare, turned around and continued walking downstairs. This time, unlike when she refused to answer in the First Division, she turned her back to Yuuko and said, "It's just a rule."

"What?" Yu Zi was taken aback, somewhat confused.

Yoruichi didn't say anything. She walked to the door, pushed open the doorknob, and stepped aside so that Yuuko could see the scene inside.

Unlike the prison Yuko had imagined, the cell was furnished with tables and chairs, as well as fences and stairs. The prisoners, dressed in white prison uniforms, were either walking around numbly, sitting at the tables, or leaning against the fences.

It's called a prison, but the degree of freedom is far too high.

"Do you understand?" Yoruichi said calmly, "Although they are imprisoned here, their ability to move around has not been restricted."

Yu Zi glanced sideways: "Why is that?"

“Because they didn’t do anything wrong, we can’t punish them.” Yoruichi stepped in. “But if we leave them alone, something bad might happen, so we locked them up here.”

Yuko followed with a puzzled look: "But how exactly is this determined?"

Yoruichi stepped aside as a prisoner staggered towards her: "Didn't I already say that? It's just what the rules say."

Yuko stepped aside, curiously observing the person.

His eyes were vacant, as if he were a walking corpse.

"I still don't understand."

Yoruichi turned her head slightly: "It's a very simple question, what do you think the Gotei 13 is?"

"Uh, the force that protects the Seireitei and safeguards the interests of the nobility?"

"Ha, you're thinking too highly of it." Yoruichi shook her head. "The Gotei 13 recruits outstanding talents from various noble families and the Rukongai, and trains them into Shinigami through the Shinigami Academy."

"Have you ever considered that some of these Grim Reapers might have left the team?"

"I think...?" Yu Zi paused, a bad feeling rising in her heart. "By the way, can I get a refund?"

"Of course, but then I'll probably only be able to see you here."

Yuko instantly understood: "You tricked me?!"

"I'll screw you over for sure!" Yoruichi seemed to have expected this and immediately retorted, "Even if you don't join the Second Division, you'll still be beheaded if you commit a crime."

"..."

Yoruichi's anger vanished in an instant: "In short, you better be serious and don't cause any trouble..."

Before she could finish speaking, a sudden gust of wind swept past her from behind.

boom! ! !

Yoruichi didn't move, but Ikuko behind her made a leg-pulling motion.

Before them, a huge crater appeared, from which thick smoke billowed.

In front of the pit, a pair of large feet lay at the opening, clearly having just been kicked away by Yu Zi and knocked unconscious.

Yuko scratched her head: "Is this what they call subduing a criminal with bare hands?"

Yoruichi praised, "The girl has a good reaction."

Yuko blinked: "A young girl? Yoruichi, you do have good eyesight."

Yoruichi's face darkened: "I really can't praise you."
