Black Catfight

It started off as a relatively normal Rating Game and Kuroka doesn't get how could Koneko get so injured in this kind of game unless she confronts the Phenex boy directly.

With that in mind, Kuroka continued watching but when Koneko suddenly changes into Sage Mode and cornered Riser Phenex, she exclaimed, "What's that!? Senjutsu!? And using that weird instant acceleration technique..."

Kuroka looked at Koneko but the latter is still intently looking at the screen, 'Right, from the looks of it, it's not the real reason she got injured.' Hence, she turned her attention back to the screen.

Even though Koneko is pushing the Phenex boy to the corner, it's not enough to defeat him. And as Koneko slowly lose stamina, Riser initiated his counter attack along with his peerage members. It pained her seeing Koneko like this and wanted to stop watching now, but she knew she could get the answer she is looking for if she continued watching.

When the referee wanted to announce Koneko's defeat, the unthinkable happened. Getting engulfed by her own flames, coming out as an adult. Kuroka was speechless at this sight. Koneko then proceeded to defeat Riser but was stopped by Yoruichi before killing the boy. This gave Kuroka another shock and a bunch of questions surfaced in her mind.

'How did Shirone do that!? What are those flames!? And this Yoruichi is that strong!? She can control lightning like her own arms and its intensity is no joke. I could hardly defend against that. I grossly underestimated her! What about that guy? Is he also that strong?'

The video stopped playing and waking them up from their stupor. Aika is the first one who reacted, "It is amazing no matter how many times I see it. Although, it also has an equivalent nasty side effect."

"... I did something like that? I can become an adult?" Koneko muttered.

"So that was the one that caught your attention? As expected of Koneko-chan~." Aika patted her head but was feeling envious inside, 'I also want that kind of form that will multiply your breast size once achieved.'

"Aika-senpai, what you're thinking is written on your face..."

"W-why are you taking this lightly!? That form is very abnormal! Although it's indeed possible to take an adult form to adapt to your own Ki, what Shirone did is let her Ki forcefully change her body which is very dangerous! And based on the intensity of Ki, it's actually amazing that you're alive right now!" Kuroka grabbed Koneko's shoulders and shook her.

Koneko didn't know what to say, but she's very happy that her older sister that she missed so much is worrying about her to this degree and ended up smiling like an idiot.

"What's funny!? This isn't a joke! Who taught you that kind of Senjutsu!?" Kuroka misunderstood her little sister's smile.

"Hohooh, as expected of a real Senjutsu expert. So I guess you also knew what will happen if Koneko's Ki which is laced by that kind of flame forcefully transforms her body." Yoruichi's voice suddenly rang behind her.

"..." Kuroka glared at Yoruichi. She guessed that Yoruichi has something to do with the Senjutsu that Koneko used and also noticed something amiss with her words, "Real Senjutsu expert?... Could it be...?" Kuroka's eyes widened at the realization and bared her fangs towards Yoruichi, "You taught her something like that even though you're not a Senjutsu user!?"

"Oi oi... Don't look at me like that. I'm a Senjutsu user alright... Even though I'm self-taught." Yoruichi just snickered at her reaction.

"Wha-!? Do you know how dangerous it is to experiment with Ki!? And how did you achieve that kind of effect anyway!?" Kuroka stood up with Koneko behind her.

"You can guess. Do you think Koneko has enough Ki within her to propel that kind of transformation?" Yoruichi is still unphased.

"...You! Are you crazy!? Messing with natural Ki is dangerous enough! Yet you're saying that you used that as an alternative power source!? Do you want your mind to be corrupted!? I don't care about you but you put Shirone in danger!" The atmosphere around Kuroka became cold and threatening.

Yoruichi grinned at her and ask, "And what are you gonna do about it?"

Kuroka flared both of her Senjutsu and Demonic Power, "I'm going to get away from this place with Shirone, even if it means putting my life on the line!"

"Kuroka-neesama.." Koneko wanted to stop them from arguing but Aika grabbed her shoulder. Koneko saw her shake her head at her and looked back at Yoruichi who still has the same smile as Kisuke when he's planning with something.

Yoruichi released her Reiatsu-Ki and a pressured dropped down on Kuroka, shocking her out of wits, "Good. You're free to try~."

But instead of succumbed to the pressure, Kuroka circulated both of her Ki and Demonic Power to the maximum degree to fend off the pressure's effects.

Yoruichi was pleasantly surprised at this sight and praised her internally, 'Good thinking! And without hesitation at all. Even though she's almost the same age as those Devils in school, she's miles ahead in terms of ability and experience. Looks like she'll be useful.'

Without waiting for Yoruichi to move, Kuroka clad herself with Ki and launched herself towards Yoruichi using her sharp claws to swipe at her.

Yoruichi in response just chuckled and stood up. She caught Kuroka's hand and tossed her away, sending her flying and only landing after reaching the 100 meters mark.

Kuroka, after landing, didn't immediately resume attacking and just fixed her stance. Around her, violet mist gathered and just as she expected, Yoruichi came after her with insane speed. Kuroka was able to see Yoruichi strike coming to her and managed to block it with her arms.

Just as Yoruichi is about to make her next move, she noticed that her feet were buried under a layer of hardened earth and would need half a second to shake it off but that's what Kuroka would ever need.

Changing the trajectory of Yoruichi's attack, Kuroko crouched down and made a hand-knife, aiming for her throat.
