Rias, Akeno and especially Yuuto were dumbfounded at the turn of events. When Koneko jumped back they finally have a response.

"H-how did you do that Koneko?" Yuuto reacted first.

Koneko also puzzlingly looking at her hand and didn't answer.

"Did you learn that from him?" Rias approached them with Akeno.

"Yes, Buchou," Koneko affirmed.

"Did you manage to get stronger?" Akeno asked.

"No, I didn't get stronger. Senpai said that it's just a trick to use more potential of the body."

"T-trick? How does it work?" Yuuto almost tripped himself at Koneko's answer.

"Uhmm, you do this by consciously controlling and circulating your demonic power throughout your body and suddenly concentrating it when you attack or defend. There's is an even more advanced technique that requires more control and I can't do it." Koneko explained.

"C-control it while moving in high speeds? I can only do it if I'm stationary and all of my focus on it." Yuuto imagined doing it himself but the end result is just self-destruction.

"What else did you learned from him?" Rias looked at Koneko as she didn't expect that her servant will grow stronger without her knowledge.

"That is, never stop moving in an actual fight even if something unexpected happens and just think of a way out,"

Yuuto's body shook as he did just that earlier leading to his easy lose.

"Another one is, to not only use your body to fight as the terrain around you can change the tides of battle." Koneko continued.

Yuuto was enlightened at her words and remember how she used her backflip to grab some dirt without his notice.

"And the rest is Kisuke-senpai pointing out my openings in my stance and how to effectively move my body from different positions."

"You learned all of that from him?" Rias couldn't believe that a master like him lives in her territory but she knows nothing about it.

"Yes, but starting tomorrow I'm going to learn under someone else who is better than him in hand-to-hand combat."

"There is someone else stronger than him? Who is he? Is he also living in Kuoh Town?" Rias is holding her head in frustration as information like this may attract other high-class devils to invite them to their respective households.

"She isn't necessarily stronger than senpai, after all, senpai might be good at hand-to-hand combat, but swordsmanship is actually his expertise."

Rias held her forehead and let out a long sigh, " It actually slipped my mind that he has a sword type sacred gear so its only natural that he is a swordsman, but to think that he can teach you to this degree and his swordsmanship is still better, we underestimated him too much."

"Koneko-chan, could you be referring to the lady with you two earlier at the shopping district?" Akeno from the side asked.

"Yes, Akeno-san. Unfortunately, that's all I can tell you about her due to the contract."

"That's fine. We know what she looks like. As long as she lives in this town and actively search for her, we'll have information on her sooner or later." Rias, who is done sorting her mind, spoke.

'Sorry Buchou, but I doubt you'll extend your investigation towards a cat with a male voice.' Koneko pities them that they'll only tire themselves out.

"Koneko-chan, he thought you how to fight, but did he teach you any technique or skill?" Yuuto continued to ask about Koneko's apprenticeship.

"Yes, a short movement technique called 'Flash Step'. However, I can only do half of it."

"Can you show us? Even if it is incomplete." Yuuto urges her as he got interested in the technique due to its name.

Koneko looked at Rias and she nodded.

Koneko turned her back towards them and said, "Please watch carefully."

They watched her not carefully, but curiously. They thought it was just a high speed dash given its name. Before they knew it, Koneko already disappeared from their sights and heard a loud sound at the distance. They turned their heads towards where the sound came from and saw Koneko crashed, felling multiple trees in the process.

All of them, without exception, had their mouth and eyes wide open.

"W-what... the hell?" Yuuto muttered.

When Rias heard this, she dashed to Koneko to check her state, "Koneko!"

The two followed and they saw Koneko stood up, with her clothes partially destroyed, dusting herself.

"Are you alright?" Rias worriedly ask.

"I'm fine Buchou." Koneko looked at her and smiled.

Akeno proceeded to repair her clothes and Rias had a sigh of relief.

"Yuuto, how fast was that?" Rias then faced her Knight.

"I'm sorry Buchou, I didn't see it clearly so I don't know. But I at least know that I'm incapable of moving in such speed." Yuuto scratched his head in embarrassment.

"Even you couldn't see?" Rias felt another head ache coming.

"He is teaching you this insane technique that makes you a human bullet?" Rias then looked at this unbelievable little girl.

"You've got it wrong Buchou. As I said, I only learned half of it. Senpai can disappear and reappear silently, although I don't know how many times he can do that, as this particular technique put a large burden to the body." Koneko explained.

Rias held her already throbbing forehead and looked at Koneko, "I still have a lot questions about him but I'll set it aside for now, just answer this final thing I'm curious about."

Rias fix her posture and gave Koneko a serious look, "Why is he doing all of this?"

"Why?" Koneko paused for a moment and then smiled, "Because he's bored."

"Bored!?" Rias thought 'He caused as so much headache because he's bored!?' She let out another huge sigh.

She looked at Akeno, "Akeno, check what is he doing right now."

"Yes, Buchou." Akeno closed her eyes to connect herself to the magic circles she had setup earlier at Kisuke's shop.

After a few moments, she suddenly blushed and gritted her teeth.

"What's wrong?" Rias thought that something has gone wrong and hurriedly ask.

"That bastard block the view of all audio-visual surveillance magic circle with tons of porn magazines, and a sound of a moaning MAN is playing in the background. He even left a note in the middle saying, 'This is my treasured collection. Please enjoy it ;D P.S. That gay porn isn't mine, I'm just curious.'" Akeno shut off her connection to the magic circle.

Rias' body was shaking before laughing out loud, "Pfft, ahahaha. Akeno, please erase all those circles. He isn't an enemy."

"That damned pervert." Koneko couldn't help but curse.

Akeno did just that as those circles are already useless, "Are you sure of him not being our enemy?"

"Yes, my instinct is telling that he's not. No, that's not it, more like my instinct is screaming at me not to make him my enemy." Rias turned around intending to go back to the clubhouse. The rest followed.

"Uhmm, Buchou, I'd like to ask a permission for something." Koneko is fidgeting.

"Hmm? What is it?" They continued walking.

"I want to move into Kisuke-senpai's place." Koneko dropped the final bomb.

All of them looked at Koneko in shock with their mouths twitching.

"K-Koneko, I didn't know you were that close to him. Be sure to let him take responsibility." Rias couldn't think of anything else to say.

Akeno and Yuuto just nodded along, they also didn't known what to say.

Koneko tilted her head in confusion at their reaction and it then finally hit her, "You're wrong! We don't have that kind of relationship!" She frantically defended herself.

"Then why do you want to move in with him?"

"For my training. Yoruichi-san said that it would be convenient." Koneko let out a long breath and said.

"Yoruichi? Is that the person who is going to teach you?"

Koneko didn't say anything and just looked at her master.

"Haaahh, fine. Just be careful of him. Don't let him 'attack' you in your sleep." Rias gave her a stern warning.

"" Buchou!? "" Akeno and Yuuto exclaimed at their master's decision.

" It's fine Buchou. Even if I'm the one who 'attacks' him, he'll probably say something like, 'Stop little girl! I'm a man and also interested in those stuff. But you have to wait 10 more years... No, wait. Looking at the pace you're developing, prolly 20 more years.' Or anything along those lines, hehehe."

They all felt a chill on their spine when Koneko said that with a smile which isn't a smile, 'This is Koneko!? Just what did that guy really do?' They all thought.

"Ahem, let's go back for now." Rias immediately change the topic and resumed walking with notably increased pace.

The two followed with their backs drenched in cold sweat.

"We should prepare to take in Issei Hyoudou. I want him even more now that I know he has a connection with Kisuke Urahara." Rias continued.

"Yes! Buchou." Everybody agreed.
