Aika's attack went passed just above her head and all the way towards the wall gouging out the bleak terrain and drilling a hole in the wall continuing until unknown depths.

Aika stood up and looked at the destruction she caused, "The hell? That's stronger than I thought it would..." She was finally reminded that her head almost disappeared from her neck due to her own attack. She turned around and saw his teasing smile and immediately protested, "Kisuke! I know that I'm at fault for doing that without even thinking and I'm sorry, but couldn't you have just sent it sideways instead of in my direction? You almost fried my hair!"

"Hahaha~ But you're fine~." Kisuke laughed at her and praised himself inwardly for teleporting the whole training ground to a backup location which is an actual underground somewhere unknown before coming here if not, it'll be revealed to these people where the actual location of this training ground most of the time and he didn't want that as this training ground could be their oasis when there is an emergency. The fewer the people who knew where is this place is located, the better.

As Aika was about to continue complaining, she suddenly stopped and dropped down to the ground without even muttering a word and completely losing consciousness.

Her twin swords reverted back to its former form, a two-meter long nodachi and her Shihakusho receded and was replaced by her casual attire.

"Well, that's to be expected. You used everything in that one shot." Kisuke then turned around, "Koneko-chan, take care of Aika here. She's fine, just exhausted."

Yoruichi took down the barrier again and looked back at the guests. They are all frozen in place and had their mouths open in shock, including Sakura.

Koneko nodded and ran towards Aika's position and carried her back in a princess carry.

Kisuke also returned while thinking, "She actually destroyed about one hundred thousand shields with just that much Reiatsu-Ki... Looks like that strike has multiple special nature in it. I can slowly figure that one out."

Kisuke took out a sheet and laid it on the ground, prompting Koneko to lay her down.

Kisuke stopped walking as he almost forgot the little girl who started all of this. He turned around and saw that she is following while intently staring at him, 'What is she thinking, I wonder? Oh well, she'll get bored after some time and leave me alone. I can't really do anything to her and it doesn't look like she plans to do anything else.'

He wanted to discuss the terms with Sona's group but he notices that they are still staring at the sleeping Aika agape, "Uhmm, excuse me. I want to discuss the terms now. I also want to go home and take a dip in the bath as soon as possible."

'Kisuke. Do you really have to discuss terms with them? Just force them not to say anything or erase their memories. Why do you have to go and give yourself some trouble?' Yoruichi suddenly sent him a telepathic message questioning his decision.

'If I force them not to speak, we'll just provoke their caretakers as we have to send them back. And we can't erase their memories as I want to take advantage of that fact. This will also stop them from messing around with us, especially the Gremory group. Even though that Rias is taking care of our little friend Issei, I can tell that she's a spoiled brat and continue what she wants to do even if it is dangerous because of pride.' Kisuke replied.

'Then it's useless even if she knows that we're dangerous for her, on the contrary, she might get us to involve even more.'

'That's where her Queen comes in. This Akeno is the careful type of person. Rias would probably listen to her not to mess with us even if she can't tell her everything. This Akeno will probably give some false report just to protect her spoiled master.'

'I see. Then what about Sona?' Yoruichi furrowed her brows

'We need a connection to the Underworld and Sona-chan fits the bill. You also know that she has a good head on her shoulders although a bit prideful but not as much as that redhead. She's the complete opposite of that brat, and our choices are only Sona and Rias. Since we also get along with her pretty well, the choice is already obvious. And lastly, I just love teasing her.'

'How big is the last criterion?' Yoruichi sighed, already expecting his answer.

'About 90%.'

'That is so like you.'

'If you gotta do something, you might as well find a way to enjoy it.' Kisuke grinned.

It took some seconds for Sona and the rest to react after Kisuke spoke, "Kisuke! What the hell is she!?"

"A Human, obviously," Kisuke answered blandly.

"Kuhh... I know that she's a human and formerly a normal one at that. How is she capable of doing that in just a matter of days of training under you!?" Sona pointed at the large hole created by Aika's attack. Tsubaki and Akeno also has the same question.

"She's a bit special you see. But as for special she is, you don't need to know. We should discuss the terms now."

Sona took a deep breath and calmed herself down, "I'm sorry Kisuke-kun. If possible, I want a few things before we proceed to our talks. I don't want to be into many disadvantages. The fact that someone like you is hiding in this little town we are overlooking is big news for us. And I also want to establish a friendly connection between us."

Kisuke smiled and said, "Sure thing, but I won't promise you that I would answer everything, but I can at least assure you that I won't lie. Ask away."

Sona stood up and said, "Thank you. That's enough. First thing, what happened to Aika-san back then?" Sona knew that Kisuke won't answer her if she asks him 'How', so she instead changes the question a little bit to try her luck.

Kisuke understood her train of thought so he stopped for a bit to think of his answer, "That's what happens when the soul is corrupted."

"Corrupted? How is the soul being corrupted?" Sona asks a follow-up question, but this time Kisuke didn't answer her and just stayed silent.

"Haah... Fine. So that transformation is like an evil spirit being born?" Sona immediately gave up her previous question and move on the next now.

"Yes." A simple answer from Kisuke, but that's enough for Sona since after they left, she has a lead where to investigate first, 'Evil spirits huh. There is not much information about them but there should be enough if I ask for the help of my parents.'

Sona asks more questions regarding Aika and what she has done these past few days but Kisuke didn't give any substantial answers.

"One last thing. Aika's last attack is comparable to the peak firepower of a strong mature High-Class Devil up to weak Ultimate-Class Devil. That's is very surprising considering that she's just a normal Human a few days ago, but what surprises me more is how were you able to casually return her attack. Urahara Kisuke, what are you?"

Due to Aika's very surprising attack, Tsubaki and Akeno almost forgot that Kisuke received it and deflected it back. They shuddered at the thought that they've been ignoring someone so strong that they would need the two peerages to work together just to defeat him. Akeno is the most affected as she and her master 'offended' him on multiple occasions.

Kisuke's smile grew bigger at her question and used his prepared answer, "These days, I'm just a lovable candy storekeeper."
