Another knock was heard on the door.

The three looked over and Rias spoke, "Come in."

The door opened and Koneko, with a refreshed look and clearly in a good mood, entered the room. Yuuto who didn't know what's happening is confused at Koneko's changes.

"Good evening, Rias-buchou, Akeno-san, Yuuto-senpai." Koneko greeted the three.

"Good evening Koneko. Looks like you had fun today." Rias smiled at her.

"Mmmh." Koneko nodded with a smile.

Akeno prepared another cup of tea and some snacks and placed it on the part of the table in front of Koneko's usual seat.

Koneko sat down and started eating her snacks.

The trio looked at her silently and Koneko noticed it but kept on eating silently and waited for them to ask.

"Koneko, why didn't you go home yesterday?" Rias first opened her mouth.

"I stayed at Kisuke-senpai's place. I got tired and accidentally slept there." Koneko replied without much hesitation.

Yuuto, who is listening to the side, was shocked, 'That Koneko!?'

"You've become quite close to him. Can you tell me what you think of him?" Rias continued ignoring the shocked Yuuto.

"Mmmh. He's a pervert." Koneko nodded and only said one thing.

The trio's mouth were twitching, 'We know!'

"But he also kind although a bit selfish. He kept on doing idiotic things even though he is very smart. He also has this natural capability to annoy everyone around him. He doesn't care what others think of him and just do whatever he wants. Did I mention that he's also a big pervert?"

Koneko spoke with a gentle smile on her face which gave another shock to the three.

'What did you do, Kisuke Urahara!?'

"I know that you can overpower him easily, but aren't you worried that he might just assault you when you let your guard down? You did mention that he is a big pervert." Rias calmed herself and continued to ask.

Koneko thought for a bit a said, "In a fight with, I can easily overpower him, but won't be able to defeat him." 'This is technically isn't a lie since he always only use strength lower than me when we spar.'

"You've fought him before and lost? Did he use magic?" Rias expression became serious.

"Yes, buchou. He did use magic to strengthen his body but I'm still stronger." Koneko said, but thought, 'That's what he said to me when we first fought. I still don't know how he strengthens himself to insane levels.'

"How many times have you fought him?" Rias expression became even more serious.

"I started sparring with him a week ago and we always spar when I come over." Koneko continued eating her snacks as she spoke.

"How did you lose? Did he use some tricks?"

"I can't really describe how I lose, but I lose to his skills."

"Skills?"

"Mmmh, Even though I'm stronger, he can play with me until I'm dead tired. I also never landed a hit on him. Kisuke-senpai also teaches me how to fight along the way."

"Never? Not at least once?" It's Yuuto's turn to be shocked now as he is also a close combat specialist and he can never do that to Koneko in a proper fight.

"Buchou." Akeno looked at Rias who still deep in her thoughts.

"If he is teaching you, why didn't we see a change in your battle style?" Rias asked and Yuuto nodded in agreement, "Right!"

"Because senpai stated that I should never use what he teaches me in a real fight until I reach a certain level of mastery. I can only use what I learned if I'm sparring with senpai, however, he already lifted that restriction earlier."

"How much did you improved?"

"I don't know. I still can't touch senpai even after using everything I learned." Koneko shook her head in disappointment, but she'll never give up to get stronger for her sister's sake.

"How about a spar with me?" Yuuto suddenly suggested.

Koneko didn't agree immediately and looked to Rias for confirmation.

"Good. Koneko, did you use your knuckle gloves when sparring against him?" Rias agreed and asked another question.

Koneko nodded at her.

"Then Yuuto, use your Sword Birth." Rias looked at Yuuto and instructed.

"Buchou?... Alright." Yuuto saw her serious expression and agreed.

"Let's move." Rias stood up and exited while the rest followed.

They arrived at an opening in the forest beside the clubhouse.

"Akeno, put up a barrier. Just in case."

"Yes, Buchou."

Koneko and Yuuto are facing each other with 15 meters between them in the middle of the clearing.

"You can start now," Rias shouted at the two.

Yuuto materialized a one-handed sword on his right hand while Koneko put up a stance.

Yuuto made the first move by charging towards Koneko and making a swipe with his sword from left to right. His speed so fast that normal humans will only be able to see a blurred silhouette.

Koneko dodges by flipping backward and sending a kick to his chin in the process.

Yuuto blocked her foot with his left hand but he was lifted backward for a few feet due to the kick's force.

It's Koneko's turn to dash towards him and Yuuto readied his stance but shocked when she suddenly throws a handful of dirt and grasses to his face. At this unexpected situation, he panicked a bit and used his left arm to block the dirt coming to his eyes.

When he looked in front of him, Koneko already disappeared and saw a white silhouette to his right side.

Yuuto readied his sword to block the incoming fist, but another unexpected thing happened that shocked everyone, even Koneko herself.

When her left fist made contact with Yuuto's sword, instead of brushing it away as she intended, it suddenly burst into pieces. Yuuto stopped moving as well as the two onlookers. Koneko remembered what her senpai said that never stop moving and thinking your next move even if something very unexpected happens. She stepped in and launched a punch towards Yuuto's face only stopping when her fist is only about half an inch closer.
