On the first day of his lockdown, Kisuke first cleaned up everything and then set up his new pieces of equipment.
This time around, he had three main objectives. The first was a reliable way to transfer between worlds. If possible, by completely bypassing the empty void and directly connecting the two worlds. He also had a feeling that if he chooses to do so, the powerful being from the void could stop them from leaving this world. He would have to make countermeasures against that.
The second main objective would be finding a way to fool the watchful eyes of that being. Since he'd already figured out that this guy had some unknown motive that involved him and his group, the best way to create a margin of safety and movements for them was to undetectably escape his surveillance.
But to do that, Kisuke would need a power equivalent to him.
It was possible to attain that through transcending, but even Kisuke himself didn't know when that could come to reality as he didn't have any concrete plan to achieve that as Aizen did. Besides, countering Chaos' surveillance through transcending would be a very stupid move, as transcending was neither an instant nor quiet affair.
The moment he transcends might become the moment Chaos chooses to deal with him and he would be in a very dangerous situation, a risk that Kisuke wasn't willing to take.
With that in mind, Kisuke and Yoruichi decided to tackle this problem on two fronts. While Kisuke tried to find another way through the clever manipulation of Magic, Ki and Soul, Yoruichi would try to find a potential 'helper' that would be at the same level as Chaos.
Kisuke's third objective, however, was currently the most important one, "Yosh! Let's start with reforming Medusa-chan's body!"
Taking out the special clear container which housed Medusa's eye, Kisuke took a good look at it again, 'Although it looks pristine, it's only the outside appearance. Most of it was already decayed with a complex Magic preserving it. Even then, that Magic only focused on preserving the eye's form and ability and did little in regard with its core structure. If I want to use this as the base for the body, I would have first to restore this to a usable degree.'
Diving into his work, Kisuke busied himself for a week straight until something knocked on his consciousness and he stopped what he was doing, before looking up with a frown, 'Line?'
The mark that he'd left on Line Arshe's soul when she reset her Level was rapidly disappearing, 'What happened?'
Without further ado, Kisuke immediately initiated a telepathic call with Serafall, "Sera-tan, please tell me what the Loki Familia's up to these days."
Serafall sensed the urgency behind Kisuke's voice and immediately answered, "I'm currently watching the situation, and more than seven hours ago, most of the Loki Familia, including all the executives went to the sewers and attacked a facility underground."
'They attacked that man-made dungeon?', thought Kisuke and immediately understood what transpired. Without proper information, it was almost certain that the Loki Familia would suffer great losses in it despite having numerous top-class Adventurers.
Serafall then continued,"Just a few minutes ago, their main force escaped from the sewers and retreated with grave injuries, including their Captain. A while after that, another batch of the Loki Familia were able to escape, but I heard it was only possible because Line Arshe distracted their enemies and was left behind. Just now, Ais Wallenstein and Bete Loga went in again to rescue her, while Riveria Ljos Alf froze the doors to keep it open."
"Thanks.", that was all that Kisuke needed to hear. Shutting down the line, Kisuke picked up his cane and disappeared from his spot.

In front of the Knossos's entrance, Riveria was gritting her teeth while the other members around her were nervously looking at the frozen entrance. Riveria was contemplating whether or not to ask for Kisuke or Serafall's help to save Line, but she knew she would just be embarrassing herself after they already reminded them that they couldn't use their help, whatever situation they were in.
'...Even then... It might already be too late.', thought Riveria with a grim expression. She had already heard from the others who were able to escape thanks to Line that she was facing a Level 5 enemy who was wielding a cursed sword, Valletta Grede, 'Hurry up, Ais, Bete.'
But all of a sudden, a familiar voice suddenly resounded beside her, "Please excuse me. I'm coming through."
"!?" Riveria immediately turned to her side and saw the familiar face, "W-when did you...?"
But Kisuke ignored her and everyone around her as he continued walking casually through the frozen entrance.
Stupefied, everyone could only see him gaining distance and slowly disappearing along with the darkness of the hall. On that occasion, Riveria had figured out his motives and asked, "Why?"
"Line-san is my precious student. I still have a lot of assignments for her, so I can't have her retire this early.", replied Kisuke, before he completely disappeared around the first corner.
Riveria could only sigh and smile wryly, 'So he would move for Line huh... I'm a bit jealous.'
Realizing what she thought at the end, Riveria immediately shook her head, 'What the hell am I thinking?'
Soon after, those around her started voicing out their concerns, "R-Riveria-sama!? When did he come here and why did you let him through!? That's Kisuke Urahara, isn't it? No matter how good he is as a Level 2, he has no chance of surviving if he were to be besieged by countless monsters!"
With a large portion of her worries abated, Riveria smiled calmly to everyone and said, "He'll be fine. If there's someone who has a chance to save Line, it would be him."
Everyone was stupefied and asked her what she meant, but Riveria just chose to stay quiet.

After walking for a minute or two, Kisuke was able to find Line's precise location and immediately used Flash Step towards that direction. When he arrived, Kisuke saw three people. Ais and Bete making complex expressions while looking at Line impaled with an ominous sword on the ground. They already gave up saving her as her life was already slipping away.
As Kisuke started walking towards them, his wooden sandals echoed through the hall, instantly catching Bete and Ais's attention.
"Who's there!?", shouted Bete in rage. But when he saw who it was, he became wary and suspicious, "You? What are you doing here!? Are you part of Evilus!?"
"Bete!", Ais tried to stop him but Bete didn't listen.
"I do not belong to Evilus nor to any other organization running this place. I'm just here for Line.", answered Kisuke calmly as he continued walking.
"Bullshit! Why would someone like you be here!? And don't come over!" Since this was their enemy's territory, Bete was wary of anything that didn't belong to Loki Familia.
But Kisuke ignored his warning and didn't stop his approach.
That, however, immediately triggered Bete's nerves and he suddenly launched an attack towards him. "Bete!!!", Ais tried to physically stop him, but he was already outside of her range.
Without any hesitation, Bete aimed a punch at Kisuke's face. But before he could land it, his arm was suddenly caught by Kisuke's right hand. Bete's eyes widened in shock, "W-what?"
Nevertheless, before he could understand what was going on, an incredible force was suddenly applied to his arm, snapping its bone before he was thrown up, crashing on the ceiling and creating a small crater on it, before dropping down with a few more broken bones, "Gahaa!?"
"I understand your wariness, but you're still too violent. You might want to work on that temper of yours.", said Kisuke casually, before resuming his steps.
"Bete!" Ais immediately went to Bete who was writhing in pain on the floor before grinding her teeth at Kisuke.
In response to that, Kisuke said with an unfeeling tone, "Don't blame it on me, Sword Princess. If that was not me, the person lying on the floor wouldn't be Bete Loga but his victim. He might have even outright killed that person with the first attack."
Ais shuddered at his words, not because of his reasonable statement, but because of the extreme coldness he emitted. It was the first time she felt something like this ever since she met him and that coldness was akin to a sharp blade pointed at her neck. The amiable shopkeeper that always used her name suddenly used her Alias in a very cold way. She hated it.
But thanks to that, she was able to clear her head and realized their mistake and said with a frustrated expression, "...I'm sorry."
"You have nothing to apologize for." Kisuke then proceeded to ignore them before kneeling at the dying Line's side, "Curses huh... Interesting."
Hearing the commotion and somewhat familiar voice, Line turned her already blurry vision to the side, "...Ki..suke...san...?"
