"I can turn you back into a Nekomata."
Kuroka's mind went blank after hearing Kisuke's offer. Kisuke did not say anything more and just enjoyed the hot spring bath while he waited for her to properly process what she meant. Koneko was also stunned because she did not think it was possible to return after reincarnating into a Devil. Yoruichi and Aika stop what they are doing because they do not want to interfere with what seems to be an important decision for Kuroka.
After a minute or two, Kuroka finally let out a voice, "W-how...?" He didn't want to believe something unreasonable could happen. As far as he knows, reincarnating into a Devil forever changes your physique and will not return even if you remove the embedded Evil Piece. The only way for you to turn 'back' is to dispose of your current Demon body and move your soul to a new non-Devil body.
Creating a new body was already a huge problem as only a few creatures could do it perfectly, but messing with the soul was another matter altogether. Touching it alone would risk being spread out and would never return. The only proven way you can transfer your soul to another body or container is by using a particular Longinus or with the help of another being with a powerful soul who is also in your body.
With all this, Kuroka did not believe that she could casually say those words but she also wished that she was able to become a Devil was some kind of trauma to her and wanted to get rid of this stigma. So, instead of questioning the possibilities, she asked him how it worked.
"Well, the whole process is still in the works so I can't do it now. But I should be able to finish it in a few weeks time. I can shorten it if I am focused, but I still have other things to prioritize. As for how it goes, I will first remove the Evil Piece influence from your body and soul and move your soul to another container. After that, I will 'fix' your body as it was before you become a Devil and return your soul into it."
"Fixing body... It was quite difficult yet you sound like you can handle souls well. I can hardly believe your words. What makes you so confident?"
"I dare not claim that I am the best in terms of soul but I am confident in my abilities. Look at that shameful glasses girl. What do you think of him?"
"Who's the shame!?"
"Ordinary humans?"
"Why don't you try to use your black flames on him?"
"What's!? When my Kasha touches him, his soul will burn to oblivion!"
"Don't worry about it~. I'll be in charge~."
Kuroka hesitated for a few seconds but still agreed to it. A small wheel surrounded by black flames appeared at his fingertips and flew towards Aika.
"I don't have a voice in this!?"
As soon as it hit Aika, she groaned, but realized that even though the black flames were burning her, she felt nothing from it.
"What's!? How's that..." Kuroka suddenly recalls when Yoruichi also took it in person and said that he chose the wrong target. He then turned his attention back to the grinning Kisuke and waited for his explanation.
"This "Kasha of yours is a spiritual attack that directly damages the soul. It won't work on people who have souls stronger than you. Aika-chan might look like a normal person, but her dormant soul force is big enough to compensate for your attack."
"What's!? How come!? Normal humans have souls that are stronger than me!?" Kuroka exclaimed but thinking about it again, "You're the reason? You can manipulate souls like this!?"
"..."
"So what is it?"
"The offer was everything I wanted apart from Shirone's safety, but I still had trouble trusting you. After all, you are very similar to the people I hate."
"That's right... Then I should use a more drastic action~."
Kuroka obviously disliked his words and prepared herself.
Kisuke looked at Koneko and Koneko also looked into her eyes, 'What are you planning now?'
"At least you believe in my skill in the soul, right?"
"... I should have."
"Then, you know that it's possible that I plant something evil directly into the soul."
It was finally about Kuroka what she was trying to say, "Basic bastard!!! Did you do something to Shirone!?" The seal on Kuroka had been weak enough that she could now fight back but did not do so for fear that she activated something that would hurt Koneko.
"Ya~." I planted something inside him. I need insurance~." Anyway." 'Even though it's not what you think. It was just a protection spell that I placed comfortably.'
"You motherfucker!" Kuroka released Koneko and stood up revealing her voluptuous body.
Kisuke was unaffected by this and replied, "I won't deny it. So then? What decision?"
"Good! I'll be your pawn! I don't care about your other offers! Don't hurt Shirone!"
Kisuke clapped, "Cool! Since you are still a Devil, we can make a binding contract. And with my soul skills, I'll be able to make something that binds that as well."
"I don't care! My first term is that you must protect Shirone from harm to the best of your ability! The second is that you have to remove everything you planted in Shirone's soul. And lastly, you are not allowed to plant anything further on Shirone and me!" Kuroka was so worried about her little sister that she did not think of the gap that Kisuke could take advantage of. The only thing on his mind was to eliminate the threat within Koneko as quickly as possible.
"good. It's my turn then. The first is that you have all the information you have. Second, you need to gather information for me. The third one is that you cannot get close and reveal any relationship between you and everyone from the Urahara Shop openly unless I agree to it. Fourth is that you should follow the same training as Koneko-chan. And lastly, you will allow me to turn you back into Nekomata when I am ready."
What Kisuke and Yoruichi want is just an eye in the dark where they can't always come comfortably. The fourth term is for Koneko. The two did not like that Koneko had actually gone through an unknown path alone, so they wanted her older sister to accompany her. As for the latter, Kisuke wanted to give it a try first to Kuroka before she proposed the same to Koneko later on.
