"I can think of two skills that you can use that have two variations each. The first one, the easier one, is using the skill that Byakko uses to make herself heavier."
Yoruichi thought about it for a moment before saying, "If I can fully control Byakko's Gravity amplification, I could even use it as a method of training. Aside from that, I just need to extend the reach of my blade using Reiatsu-Ki and it would have a similar effect as space-cutting just from the sheer weight that could be applied as a force multiplier. With mastery, I can use and take advantage of momentum by frequently changing the weight of the blade."
"And if you can extend that ability to your opponents, you can easily disrupt their balance by interchanging the Gravity around them."
"Extending that ability, huh... Just from the initial impression I have, I can tell that it's going to be tough."
"You have to if you want to use the next skill that I'm about to suggest."
Yoruichi looked at him silently and urged him to continue.
And using luminescent strings of Magic Power once again, Kisuke formed a three-dimensional grid, "Once you're able to extend your ability to amplify the earth's gravity, you shouldn't be far off from directly manipulating space itself."
"By compressing space directly, you won't just be creating an artificial Gravitation Field, but those in the middle would also be crushed and implode if the compression was extreme enough. On the contrary, if you expanded space, those in the middle would be torn into pieces by pulling forces if you do it fast enough, but that would be extremely hard to do and not very energy-friendly. Instead, its main application is creating a space between you and your opponent, which is normally impossible."
After watching Kisuke's demonstrations for a few minutes, Yoruichi closed her eyes and imagined herself using it in battle. After a few more minutes, Yoruichi opened her eyes and said, "This is very dangerous, not just for my opponents, but for myself too. One mistake and I could crush myself to death."
Kisuke just sipped his tea and let her contemplate about it more and he was not disappointed as Yoruichi continued after a few more seconds of silence, "But if I can compress and expand at the same time, I could basically just use a step to transverse a great distance and that could be a lot faster and more flexible than Flash Step."
Kisuke smiled and said, "That's technically how a wormhole works. With proficiency, you should be able to move as if you're using an instant teleportation technique."
"I see... Byakko really isn't wrong when she told me to rely on you."
However, Kisuke shook his head, "I surmise the reason you're thinking of isn't the case. While you have to learn how to use her abilities, Byakko could probably do all of that as naturally as breathing since it came from her instincts. Since it came from her instincts, she might have a hard time to explain the technicalities of her ability. So that no unnecessary accidents occur, she chose to rely on outside assistance."
Yoruichi's eyes widened slightly before she smiled, "Now that I've thought about it, that might have been the case." If this is indeed true, then it's a very good sign for Yoruichi. It means that Byakko has been opening herself to her more than she initially thought.
Yoruichi then stood up and started stretching, "In any case, before I could do all of that, my body has to be fully capable or I'll just be a baby with a very sharp knife. However, this is problematic. Although I can train to get more strength, durability is a different story."
"That, I actually have an idea."
Yoruichi looked at him for a few seconds before replying, "I have a feeling that it won't be a very pretty idea."
Kisuke smiled wryly and said, "Listen for now. As you've known, Shinigami and Hollow are just two sides of the same coin. With that in mind, I've been trying to convert Hollow arts into Shinigami arts."
Yoruichi immediately got an idea but waited for Kisuke to explain, "Which one exactly?"
Kisuke looked at her grin and said, "High-Speed Regeneration."
"Seriously?"
"Yep~ Though I am not yet done with it, I'm making great progress. One of these days, it should be completed and initial testing can start." There are many Hollow arts that Kisuke wanted to convert, however, with Yoruichi and Aika in mind, he prioritized something that could save their lives in case they received a fatal attack.
Yoruichi replied with a twitching mouth, "That's really a ridiculous idea... You're just about to invalidate most of Healing Kidou Arts. Anyway, even if I can regenerate, how will that solve the problem with my body's durability?"
Yoruichi already guessed what Kisuke wanted her to do. However, she still didn't know how repeatedly taking damage would increase her defenses. At that point, a certain figure entered her mind and a light bulb went off her head.
But before she could say anything, Kisuke beat her to it, "Oh my~ Have you forgotten our good friend Askin Nakk Le Vaar?"
"No way I'm going to forget that almost unkillable bastard. Are you saying that you managed to replicate even that guy's ability?"
"Almost. Even to a small extent, I can't exactly replicate his ability. However, if it's just being immune to your own aspect, it's possible... After going through a bit of hell, that is."
"Indeed... I don't need to be immune to any attack. I just have to be immune to my own ability and everything would be fine," She then looked back at Kisuke and said, "I never expected it to be easy! When can I go through it?"
Kisuke rubbed his chin for a few seconds before answering, "A week or two? I still have to complete and test those techniques and in addition to that, I have to prepare a special room for you where space could instantly be stabilized in an emergency. Your ability won't just hurt you but could also kill you outright so we have to be extremely careful with the implementation."
"You're done with your secret talk, nyaa?" Kuroka's voice suddenly resounded beside them. Although they don't tell her any details regarding their past organization, she's already happy that she's trusted enough to let her hear their conversation. However, she's also slightly upset that she's been entirely ignored until now.
Kisuke chuckled and ruffled her hair, "Yep. We're done. For now, let's return to the surface to turn that horn in. Thanks to what we've done here, the attention you'll be getting is lesser compared to mine."
Kuroka's eyes shined and immediately stood up, "A little bit of vacation? Let's go shopping, nyaa!"
"Ahahaha. Alright. Let's do it. And it's also about time to check Serafall's reports regarding what's been happening in Orario."
Yoruichi eyed him and asked, "Wait, you've been ignoring her reports until now?"
"There wasn't anything that's been tagged as an emergency so it's fine."
