Kuroka and Koneko reached the hot spring and Kuroka felt something amiss, "This the hot spring you're talking about-nya?"

"Yes." Koneko stopped and looked at Kuroka's reaction.

Kuroka furrowed her brows and get around the hot spring. Still not satisfied with her inspection, she crouched down and dipped her finger in it. However, just a split second, she took it back in shock, "This!? What this Shirone!? Such pure Ki! How did it gather so much in this place!? Where are we anyway!?"

"Everything here is Kisuke-senpai's creations."

"His creations!? I can understand this place, but not this hot spring infused with pure Ki!"

Koneko didn't speak but pointed at the other hot springs in the vicinity.

Kuroka followed where she pointed and saw other hot springs at the distance, "Could that also be..." Kuroka wanted to say Ki but stopped herself when it felt very different from the first hot spring. She inspected the other two hot springs like she did with the first one and was shocked again at the result, especially from the last one, "Pure Mana!? and the other one is... What this!? Scary!" She already forgot her 'nya' at the end of each of her sentences.

"I also don't know the last one. Only Kisuke-senpai and Yoruichi-san seem to use it."

"Ne Shirone, Are really sure that he made all of this?"

"Yes. I sometimes watch him do all sorts of weird things."

"...This is bad-nya..."

"What is it, Kuroka-nee?"

"This is a big secret, and you just led me here. If it were to be known to the whole world he has technology like this, then all sorts of troublesome and dangerous things will chase after him..."

"...That bad?"

"Of course! Any attempt gathering pure energies like this is are very rare, not to mention, those who succeed. And the utility of pure energies is very tempting ranging from domestic to military use!"

"Hooh... It's good that you know a lot of things. It makes things easier for us." Behind Kuroka, A black beauty suddenly appeared.

"!?" Kuroka turned around and jump backed bring Koneko with her, How did she sneak behind me!? I'm constantly using Senjutsu to scan the surroundings!' Her back is drenched in cold sweat at the thought of she could have assassinated her without her being aware. Due to the nature of her group, she can't help but think that way.

"Who are you!?" Kuroka glared at the dark-skinned beauty and held Koneko's hand tighter. However, Kuroka didn't wait for her to reply and immediately cast teleportation magic which she is proud of, but to her dismay, her magic was canceled as there is a mysterious force broke the magic circle while it was still forming, 'What!?' She panicked even more but didn't move from her spot and just readied herself for the latter's further movements.

"Teleportation is restricted in this space. If you can't use any circle that is complicated enough to confuse the system in place, then it'll just be broken up like what happened earlier." The dark-skinned beauty grinned at her.

Kuroka became even more vigilant against her, 'What the hell was that!? I never heard of something like that before! At most just a restricted space that teleportation magic can't penetrate, but messing up the magic circle while it's still forming? Impossible!'

"Oh, and just because I'm speaking in front of you and I have an obvious threat to you, you shouldn't neglect your surroundings." While the dark-skinned beauty is still standing from her position, Kuroka heard her voice behind her, scaring the heck out of her. She hurriedly turned her head and a finger poked her cheek as she did. Kuroka is now having a nervous breakdown, as the figure in front of her melted away and the dark-skinned beauty is now behind her, still grinning, 'H-How is she doing this!?'

Before she could retaliate, however, Koneko's voice rang out waking her up, "Yoruichi-san, please stop messing around Nee-sama. I followed your instruction and have her see this place not for you to prank her."

Yoruichi took back her hand and jumped back, "Hahaha, my bad. Talking to people who work in the darkness just excites me."

"Darkness?" Koneko tilted her head in confusion.

"Yep~. Your older sister is probably some assassin or a scout for a small team that works in obscurity." Yoruichi, without regard towards Kuroka's changing face, answered Koneko honestly.

"W-what are you saying!?" Kuroka retorted in trepidation. She still wants to keep Koneko in the dark as her work right now is not very admirable and she didn't know how she should tell her. Should she tell her sister that she's part of a terrorist group?

"Nee-sama..." Koneko looked at Kuroka dumbfounded.

"Shirone..." Another anxiety is taking over Kuroka. Just as they make up, this revelation is now threatening to break it up again. If it were to be the past her, she wouldn't actually mind Koneko knowing the truth as she thought that Koneko still hates her, but now, she didn't want to risk it.

"Don't look at her like that, Koneko-chan. Sometimes, some people have no other choice but to choose this kind of path to survive. And considering her history and experiences, it's understandable." Kuroka is trying to find the right words to explain the situation to Koneko or try to cover it up, but her mind blanks out trying to think of a way out. Yoruichi this time, however, helped her out to her surprise.

"..." Kuroka stared at Yoruichi suspiciously but she's still mindful of Koneko's reaction. Koneko is currently looking down looking troubled and this worried her.

"Kuroka was it? Welcome to the Urahara Shop's Headquarters... Now that I said it, Aika has a point. The name's too lame." Yoruichi largely ignored their reactions and go on her own pace.

"I'll explain things to you and to Koneko here. Follow me. I lead you to the proper hot spring." Yoruichi continued.

Kuroka still wanted to ask many questions, but choose to follow her first as she didn't seem hostile. She didn't let go of her guard though. On the contrary, she increased her vigilance to the point that it's putting stress on her mind, but this is all needed, especially in this unknown place filled with mystery.
