All Jun heard in the Tenth Division was the chaos following Uryū's Light of Rain. Having not encountered Quincy for a long time, the Soul Reaper were utterly bewildered.
Jun quickly received a communication from Hell Butterfly, announcing that the four-person group was Ryoka) and warning that one of them was Quincy, tentatively identified as such, along with Ichigo Kurosaki, who had received power from Rukia in the World of the Living. All teams were warned to be cautious.
Jun sent out the message and then stopped caring about it. Shunsui Kyōraku did the same thing in the original work; in fact, most captains don't get involved in these matters.
In the original work, Ichigo entered from the outside. Their first breakthrough point was the outer wall area of Seireitei, which was much better than the area around the Gotei 13.
First, the terrain is complex; the area where Ichigo and Kenpachi fought is easy to escape from. Second, the Seventh Division doesn't assign many patrol missions to that area, unlike their own units which are mostly on patrol.
Yoruichi probably knew all this, but it's unclear how they made their choices. Jun felt that this group's strength was definitely not an issue. Then Jun received a second message from the Hell Butterfly, ordering members of each squad after the 20th seat to avoid contact with the Ryoka as much as possible.
Along with this order, the top twenty members of each patrol team were urgently summoned. While this reduced the number of personnel did give them a chance to escape, a one-on-one fight wouldn't be so easy.
After all, the current timeline is different from the original work. The single-digit seats in each team are all at the level of Vice-Captains in the original work, while those veteran Vice-Captains in the original work, such as Nanao, are now just one of Jō's vice-captains, but their strength is no less than Soi Fon's.
Even more Kongbu is Jō, who is definitely Captain-level strength. Jō is Jun's younger sister and the former record holder for graduating from the Shin'ō Academy. Let's put it this way: if Sado were to break into the Eighth Division like in the original work, he would be facing four Captain-level. That would be terrible!
Meanwhile, Tōshirō had arrived at the scene. Looking at the Soul Reapers ' horrific state, he realized it wasn't actually that bad; not a single person had died.
After inquiring about the situation, the Little Lion chased after the four who had retreated. No one knew of Yoruichi's existence; Asada Ayu, who had been knocked unconscious, was still asleep, but even if he were awake, he wouldn't know what had knocked him out.
The Little Lion's Spiritual Reach was over 400, and his perception was incredibly high. He followed the remaining Spiritual Power of the group and found their way there. However, as he followed, Tōshirō discovered that only two strands of Spiritual Power remained, and the location had moved to the vicinity of the wall, making the terrain more complex.
"Kakushitsuijaku!" The Little Lion used this move directly, but it didn't find a single target.
The Little Lion's Kakushitsuijaku could cover half of the Seireitei. He didn't believe the other party could run that fast, and besides going through the main gate, there was no way to leave the Seireitei. This group must be in the walled area.
Since he couldn't find it, he would keep chasing it relentlessly. The Little Lion was skilled and daring; he refused to believe that the other party could defeat him!
With the addition of a cat, the four-person group fled frantically. Yoruichi, originally the captain of the Stealth Force, was most skilled in this area. She immediately noticed the problem of their Spiritual Power dissipating and warned them. However, a problem arose: Sado and Orihime were originally human. Due to their physical bodies, Spiritual Power dissipation is different from soul dissipation. Now that they were in spirit form, they couldn't control it no matter what they did.
But there was nothing she could do; she could only try to control the situation. In this state, Yoruichi, while fleeing, also left behind surveillance footage, which showed the Little Lion tracking her. So, instead of taking the others back, she decisively led them into the walled area.
However, Yoruichi quickly realized it wasn't working; Tōshirō was still chasing. Fortunately, the surveillance footage Yoruichi had left behind showed Tōshirō's "Kakushitsuijaku," which Yoruichi countered with Kidō Disguise.
The Disguise Technique is Kidō developed by Urahara, and Jun also developed it. The principle is a black Cloak that blocks Spiritual Power. The Kidō used by the Visoreds to reduce their presence was also developed later. The Disguise Technique is the culmination of these techniques and is extremely useful.
However, the weakness of the disguise technique is its limited range. It's effective at covering a few people and setting up Barrier, but it's useless for long-range attacks. Yoruichi knew this, and she might not be so lucky to see Shiro-chan use the Kakushitsuijaku technique again.
So Yoruichi used her Spiritual Power to envelop Sado and Orihime, "Releasing some Spiritual Power."
The two quickly did as Yoruichi instructed. After absorbing some of their Spiritual Power, Yoruichi used the Kidō: Insect March.
This technique is a unique Kidō of the Shihoin Family. It works by extracting Spiritual Power, turning it into insects, and then letting the insects run around. The Spiritual Power left behind in the insects is very weak, but still detectable by others—essentially a decoy.
Tōshirō chased after them, he noticed the Spiritual Power had split. He frowned. "Did they split up? Or did they discover my pursuit and decide to abandon their comrades, leaving them to fend for themselves?"
Tōshirō frowned even more as he thought this, because he despised this method. With a cold snort, the Little Lion chased after one of them, and soon he saw a small insect made of Spiritual Power crawling on the ground.
The Little Lion's temples bulged with anger, but after thinking for a moment, he laughed again, "Haha, fine~ I lost, Kakushitsuijaku!"
Another Kakushitsuijaku, but still to no avail. Tōshirō crushed the insect, then used a wisp of his Spiritual Power to crush another insect he had detected. He returned to the starting point and waited for about a minute.
"Kakushitsuijaku!" Another shot, but still no luck. The Little Lion sneered and, once more, "Kakushitsuijaku!"
Still no luck this time. Tōshirō frowned, realizing something was wrong. "Did it really get away? Kakushitsuijaku!"
Still empty-handed, Tōshirō snorted and left.
Over on the five-person group's side, four of them huddled together tightly. Yoruichi Nyan maintained her disguise jutsu, not removing it even after the Little Lion left. Just as Ichigo was getting impatient, the Little Lion suddenly returned and unleashed another Kakushitsuijaku.
Feeling the Spiritual Power spreading around her, Yoruichi suddenly broke free of her disguise, shouting, "Run!"
The group quickly followed Yoruichi, running at full speed. After traversing the walled area for an unknown amount of time, they reached the gate. Yoruichi attacked the gatekeeper, rang the doorbell, and the strongman outside lifted the gate. With a shout of "Charge!", Yoruichi led the group into Rukongai.
"Phew~ We should be safe for now," Yoruichi finally breathed a sigh of relief.
"Where is this?" The four of them were also completely bewildered. At this moment, Jirōbō, the gatekeeper, caught up with them.
In the original story, it was Jidanbō from the west gate, but this time they encountered Jirōbō from the south gate. This Jirōbō is quite different from Jidanbō; he's much fiercer, yelling, "Who are you people!?" before charging at them.
"Wow!! A giant!?" The four were stunned by the creature's enormous size. Jirōbō was even larger than Jidanbō, wielding his twin hammers, before being punched back by Sado.
"So weak!" The four of them were completely dumbfounded.
Yoruichi glanced casually at Jirōbō, who was lying on the ground after being hammered, and said disdainfully, "That's just an ordinary Dead Souls, given a special forged weapon. Although it's huge, it's not Soul Reaper. These guys aren't smart enough. Let's knock them out quickly so we can get out of here."
"Oh~", Sado walked over and delivered a powerful punch, rendering the still-struggling Jirōbō immobile. "I didn't kill him."
"Enough talk, let's go," Yoruichi said, not having time to waste with the four. She led them to the outskirts of Rukongai (the 26th district of the city). Once there, Yoruichi wiped the sweat from her brow, "Thank goodness we're still here."
At the Kūkaku Shiba residence, the banner held up by the two large hands and the enormous chimney behind it are actually cannons. Has no one questioned how the Shiba family managed to move with that thing in the original work? The original story mentions the Shiba Clan moving multiple times, and Kūkaku Shiba's house—is that a house that can be moved just anywhere? Perhaps the Shiba Clan has a secret moving technique passed down through generations?
The arrival of the group naturally caught the attention of Koganehiko and Yin Yan. These two were servants of the Shiba Clan, and among the few truly loyal servants. They were the two Manchu remnants from the original work, utterly useless.
Their only purpose was to recognize Yoruichi and quickly usher her inside.
Kūkaku has transformed her house over the years to look exactly like the one in the original work, making it incredibly powerful. She's currently waiting in the hall, and when she sees Yoruichi enter, Kūkaku exhales a smoke ring.
"Long time no see, Yoruichi"
"It's been a long time, Kūkaku."
The four were completely bewildered. They didn't recognize any of them and knew nothing. Kūkaku, seeing them as newbies, laughed, "These four behind you are the little guys who caused such a commotion in the circle just now, right?"
"Exactly~", Yoruichi walked to Kūkaku's lap and lay down.
Kūkaku handed the pipe to the prosthetic arm, then petted the cat with her own hand, scoffing, "Judging from your appearance, you're really in a terrible state! How did you end up outside?"
"You're just talking nonsense. Is that a place for a human to stay?" Yoruichi Cat was enjoying being petted, and her voice became lazy.
"Hehe~, you must be tired after running around all day. You guys go and rest first. It's absolutely safe here. We can talk about it tomorrow, Ganju ~!" Kūkaku called out, noticing her younger brother wasn't there. "Pah~ that idiot! Going out at a time like this. Come with me."
The group was led towards the guest rooms. At this moment, Ichigo finally couldn't hold back any longer and asked, "Where is this place!?"
"This is Rukongai)."
"Uh, what place is that?"
"That's Rukongai, where ordinary Dead Souls live. The Seireitei, which you're going to, is where Soul Reaper) live. It's that simple."
How do we get back?
Kūkaku glanced at Ichigo, making the latter shudder. "You want to go back now? Are you out of your mind? You just caused a huge commotion, and now is the most critical time. If you want to go and die, I won't stop you. Just leave my house now and go in through any gate. I don't believe those idiots can stop you. Your Spiritual Power can open doors without any problem."
Ichigo was speechless. Kūkaku snorted coldly, then smashed Ichigo's head with his pipe. Ichigo, dazed and confused, yelled, "What are you doing?!"
"I'll teach you a lesson," Kūkaku said, checking her pipe to see if it was damaged. "So you're Ichigo Kurosaki, aren't you?"
"Oh yeah, so what?" Ichigo huffed, "Why did you hit me!?"
"Haha~", Kūkaku laughed heartily, completely bewildering Ichigo. After calmly exhaling a smoke ring, Kūkaku asked, "Do you know what your father's original surname was?"
Ichigo scratched his face, looking completely bewildered. "Shiba? I think that's who it is. What's wrong?"
Do you know my last name?
"What could Ichigo's brain possibly remember?" Ichigo said. "The banner outside says ' Kūkaku Shiba, 'Uryū and you are Kūkaku, so your family name Shiba. Could it be..."
"You're quite clever, little brother with glasses, much smarter than me, your cousin," Kūkaku Shiba suddenly slammed her pipe down again, hitting Ichigo head and drawing blood. "I'm your idiot cousin, and I don't know how my Isshin could have given birth to such a moron? Hmph~ Now, do you have any objections to my arrangements?"
Ichigo swallowed hard. He realized his cousin was a bit too fierce, and backing down seemed like the best option. Kūkaku's lips curled up. "Come with me, enough talk!"
Having dealt with Ichigo, there were no more questions. The group followed Kūkaku to their guest room, concluding their first day in Soul Society.
