"Hey~ kids~ assemble!" Shopkeeper Urahara called over the four who were still training, holding a document. He handed the document to them as they arrived. "This is a document just issued by Soul Society. Rukia's death sentence is finalized, and it's the most Kongbu and rarest of all— the Sōkyoku Execution."
What is that?
"It's hard for you to understand even if I explain it now. You'll understand when you get to Soul Society. In short, it's a very troublesome punishment that causes immense pain to the Soul Reaper and requires a long preparation time. It's the most suitable punishment for those who plan and prepare for it."
However, the four didn't understand what Urahara meant. In fact Rukia was sentenced to the Sōkyoku Execution entirely because of Aizen's machinations. Over the past few centuries, the power of the Retainer faction had drastically decreased due to the Second Division's withdrawal from the Retainer faction. At this time, Aizen seized control of the Central 46.
In the original work, Aizen also controlled the Central 46, for the same reasons and in the same way, choosing Sōkyoku Hill as the execution site, solely to keep it far away, while also having numerous other purposes.
This plan can be described as incredibly meticulous. Why? First, there will inevitably be people who try to stop Rukia's Execution. As mentioned before, Rukia's crime doesn't warrant such a punishment, and there will definitely be people who will object.
However, this punishment is the Sōkyoku Execution, and the Captain-Commander is in charge of administering it. Therefore, to save Rukia, the Captain-Commander must be taken away. As long as the old man is on that hillside, the Execution will definitely continue.
Once the old man is taken away, he definitely won't come back, for reasons I've already explained. Then there won't be many strong individuals left on the hillside, especially Kyōraku and Ukitake. It's only they who will stop the old man; no one else can persuade him otherwise.
Now let's look at the remaining people on the hill. Soi Fon was taken away by Yoruichi, Unohana went to rescue people, Shiro-chan is investigating the truth behind Aizen's death. So, what's left are Byakuya, Komamura Dogdog, Gin Ichimaru, and Kaname Tōsen. That's it. Of the thirteen captains, only four remain, and two of them are Aizen's men.
In the original work, Kenpachi also caused trouble, which allowed him to hold off the dog and the blind man—a perfect storm of circumstances, giving Aizen upper hand in every aspect.
Look how meticulously this plan is done. This is a situation Aizen deliberately created. Even if there are some mistakes, leaving a few extra, such as Soi Fon and Tōshirō, is still within Aizen's tolerance for error. As long as the old man isn't around, everything is fine.
Having understood all this, and now that Jun is here, I wonder what changes Aizen will need to make? Jun expresses genuine anticipation, while on the other side of the World of the Living...
"The plan is for a month from now, but we need to be careful. To get to the Soul Society, we need to go through the Dangai. This time, for the sake of a surprise attack, we won't use the full space gate, because if we use the full space gate, the Soul Society will sense it."
"In that case, you'll face Endless pursuit and interception the moment you step out. Only by breaking through space directly within the Soul Society Dangai using the complete portal can you achieve your surprise attack objective. So, are you ready now?"
The four exchanged a glance. "Of course!"
The Shopkeeper smiled happily, "Yoruichi ~ you lead the Linglu."
"Got it~", Yoruichi jumped onto the Shopkeeper's shoulder, "You guys, you have to stick with me!"
"Mingmo ~ Are you sending anyone from your side?"
"Yes, yes!"
Mingmo brought over a woman with her face covered. The Shopkeeper squinted, somewhat surprised, "Are you really going?"
"Hi~, I can't wait!"
"Eek yeah~", Urahara and Yoruichi exchanged a glance, both speechless. Their attitude only fueled the group's curiosity about this woman.
"Then I'll open the door."
As soon as the Shopkeeper finished speaking, he pulled something out of his pocket and laughed heartily, "Hahaha, I forgot, I forgot about this!"
The five people and the cat stumbled together, and the Shopkeeper burst into laughter, "Hahaha, this is Reishi Converter. This is a tool that will allow you to directly transform into souls from your current state. Living bodies cannot stay in the Soul Society; there is no food for the living there."
"Go on in, I'll open the door right away," the Shopkeeper said, snapping his fingers. A spatial gap appeared, and then he clasped his hands together, merging the gap with a conversion device. The Shopkeeper pointed inside...
"Let's go~", Yoruichi rushed in first, followed by Ichigo, Sado, Orihime, Uryū, and unknown woman.
Unlike the chaotic events of the original story, Yoruichi Meow's cat bell cooled down, and she jumped onto Sado's shoulder. "Kid~ give me a full-force punch in the direction my bell's beam is pointing!"
"Oh~!" Sado shouted, his Spiritual Power surging forth to form the Giant's Right Arm. The Spiritual Power continued to build until the entire arm began to swell. "Giant's Strike!"
The immense force utterly destroyed the chaotic environment within the Dangai, and at the same time, space suddenly cracked open. Yoruichi's cat bell rang again, and space transformed into a circular, regular breach.
"Follow me~" Yoruichi said and jumped inside, followed by the other five who filed out.
"Where is this?" Ichigo and the others were stunned as soon as they emerged. It was a huge manor, with pavilions, towers, bridges, and flowing water. The group had never seen anything so grand before and were all awestruck.
Yoruichi- neko wore a nostalgic expression; it wasn't easy for a cat to make such an expression. "Follow me, don't get lost."
The group followed Yoruichi Cat through a maze of twists and turns, dodging several people dressed as servants along the way. With the cat leading five people, they finally arrived at a large room.
Yoruichi jumped onto the bed. "You guys rest in this room or the next one for a bit. I'm going out to gather some information."
The mysterious woman suddenly spoke up, "Do you need my help?"
"Do whatever you want, but it wouldn't be good if someone spotted you right now, would it?"
"Hmm~ I think Jun should have heard from them by now, right?"
"Oh? You can always contact Soul Society from your side, right? In that case, we'll wait a bit."
However, before the two could finish speaking, a figure appeared in the room. No one except Yoruichi reacted in time; the figure immediately embraced the mysterious woman.
Why is your face covered?
"I'm afraid of getting caught and causing problems."
"So what if you found me? I'm here."
"Whee"
Ichigo and the others initially wanted to question her, but seeing how familiar the mysterious woman was with the Soul Reaper, they didn't interrupt. The person who arrived was, of course, Jun. Jun lifted the mysterious woman's veil, Isuzu smiled charmingly at Jun.
However, Isuzu is ultimately an Arrancar, and her Hollowfication Mask is on her hair, which appears in clumps. Uryū noticed this.
"Is this an illusion?"
"Hey, Uryū brat! Don't think I won't discipline you just because I know your dad!"
Uryū was speechless at Junichi. The reason Uryū was training with them was because Ryūken had agreed, and Jun's words made Uryū realize the situation.
"You... you're the one..."
The others looked at Uryū with puzzlement. "Why are you so excited?" But Chun quickly made them even more excited.
"Ah~! I am the person behind Mingmo, the captain of the Tenth Division of the Gotei 13 in Soul Society, Jun Shimizu."
"Eh~!???"
Junichi waved his hand to set up the Kidō, otherwise his shout would have attracted everyone around. Junichi smiled and said, "Don't worry, you can cause as much trouble as you want here. As long as you don't go too far and kill any important people, your lives will be safe."
"Who is the important person?" Uryū asked. He had essentially taken over the conversation among the group; this was a testament to his intelligence.
"Well," Chun hesitated for a moment, "We need to be careful with the handsome and good-looking ones. If they're the kind of people who are unsightly, we should just kill them."
But that's just the truth, right? Those who were lying down in the original work were all unattractive, while the handsome and beautiful ones were all fine, no problem.
Is there anyone I need to pay special attention to?
"Emmm, probably single-digit positions in each division," Jun said, rubbing his chin. After all, the timeline is different now; single-digit positions are more likely to be viable. This is why those Vice-Captain from the original work now have double-digit positions—talent is useless if their experience is too limited.
Jun then explained to them what the Gotei 13 did, and said, "Pay attention to my Vice-Captain, his name is Tōshirō Hitsugaya. He's an easily recognizable little guy, looks about Jūshirō years old, with silver hair and a spiky hairstyle. This kid has Captain-level strength. If you encounter him, just surrender. Of course, not surrendering isn't a big problem either; he can easily capture you."
"And there's another one to note: the new captain of the 11th Division Kenpachi Zaraki."
"Zaraki!? Isn't that Azashiro?" Yoruichi was startled, especially since she knew Azashiro's strength.
Chun scratched his face. "I guess this is my problem. I taught Zaraki to complete his Shikai, and then more than ten years passed, and recently, Zaraki hadn't understood it. That kid just went all out and defeated Azashiro. It's not that I'm biased, Azashiro really lost."
"My God, what level is that Zaraki?!"
"That's hard to say. Judging by its power, Zaraki's release is considered Sealed Blade."
"My God!!" Yoruichi and Isuzu exclaimed in unison.
The four younger ones seemed to be listening to gibberish, but Chun explained with a smile, "Because the power to unleash this thing is too strong, it's the kind that could easily destroy the Soul Society if you're not careful, so it's not allowed to be unleashed within the Soul Society. That's called Sealed Blade, Zaraki is one of them."
"And this guy is a War Demon who likes to pick fights all the time. He's basically challenged everyone in Soul Society. You newcomers will definitely be his targets. As for any of you who encounter him, I suggest you fight him. It's impossible not to fight. Show your strongest strength, and if you survive, surrender as soon as possible. He won't kill you."
The group's faces turned green with fear. Jun didn't mince words, "I suggest you swagger out of this house right now. That way, when the Soul Society finds out, they'll basically know that Yoruichi and Urahara are backing you."
"Don't underestimate these two~", Jun said, grabbing Yoruichi and hugging her. "One of them is the former Second Division Captain, and the other is the former captain of the Twelfth Division. They're both formidable figures, and they're quite popular. Apart from scoundrels Zaraki, most people will give you face if they know you came from here. They definitely won't kill you, of course, only the upper echelons. If you get slaughtered by some double-digit number or some lowlife, hehe."
That only proves one thing: you've come to the wrong place.
