Yoruichi suddenly Kisuke's rampaging Reiatsu and knew something just went wrong.

Koneko and Aika also felt something very oppressive is pressuring them, "W-what is that!? Yoruichi-san! Are you still pressuring me!?" Aika cried out loud and looked at Yoruichi. Koneko stayed silent and also looked at Yoruichi. She guessed something was wrong from seeing Yoruichi's facial expression.

"You two leave the training grounds now." Yoruichi didn't look at them continued to confirm the Reiatsu Kisuke is releasing, 'No doubt. This is a Hollow's Reiatsu.'

"No! Something happened to Kisuke-senpai, right? Please take me with you!" Koneko shook her head in refusal and raised her voice towards Yoruichi.

"What!? Kisuke? Did something happen to Kisuke? What is it!? Are you going somewhere? If that's the case, please also take me with you." Aika reacted at Koneko's words and looked back and forth between Koneko and Yoruichi. If something really happened to Kisuke, she naively thought that maybe she could be some help.

"No, it's too dangerous. Kisuke probably lost control of his powers and on a rampage spree." Yoruichi didn't want to take both of them, but she's also conflicted as she wants to show them someone who lost control of themselves due to their powers, especially the both of them are bound to go through it too.

"It's Kisuke-senpai we are talking about here. He probably already predicted this and set some necessary safety precautions." Koneko reminded Yoruichi of Kisuke's personality. She also really wants to see how someone loses control of themselves, as there might be some truth to her big sister's rampage due to the use of Senjutsu even if it is for her little sister's protection. Koneko thought that her mind was clouded at that time and she could have made a better decision for both of them. Although because of that, she met Rias, her peerage, and Kisuke, along with Yoruichi who is helping her gain strength, so she regrets nothing.

Yoruichi might have been too worried about Kisuke and didn't think of that. She gets hold of herself and said, "Fine. But be ready to use those pendants to get out of here when things get dicey. And both of you can only watch from the distance. Am I clear?"

"Yes," Koneko affirmed.

Aika is fidgeting while watching them converse. After they were done, she immediately suggested, "Shouldn't we hurry? If I can do something to help, I'll do it."

"You can't do anything as you are now. Be a good girl and follow Koneko's lead. Also, remember that you may also experience what is happening to Kisuke right now, and you can't back out anymore." Aika swallowed her saliva and she heard what Yoruichi said. Yoruichi then proceeds to put the two of them on her shoulder and used Flash Step to arrive on an elevated rock 50 meters away from the barrier Kisuke put up earlier. Yoruichi then left the two of them there and approached the barrier to strengthen it further.

Aika and Koneko saw Kisuke's current state behind a hexagonal barrier and was shocked. Kisuke is howling to the air with his arms wide open, but this isn't what shock Aika and Koneko, it's the white matter that slowly enveloping his whole face and is forming a bone-like mask. Kisuke's eyes also turned strange as his sclera turned pitch black and his pupils turned it a glowing green color. But what worries them the most is the big hole in the middle of his chest where another batch of white matter comes from and slowly consuming Kisuke.

"W-What's this?" Aika asked Koneko who is beside her clutching the pendant they receive from him earlier. Aika is feeling overwhelmed as this is the most supernatural thing she saw since yesterday, 'Is he turning into a monster? Yoruichi-san said that I will also go through this. I so wanna quit. But is he in pain? He started banging the floor now.'

"I don't know. It's also my first time seeing Kisuke-senpai like this." Koneko replied to Aika's question, but she is also asking herself, 'How can he stay alive even with that giant hole in his chest? Please be safe, senpai. I still want to learn a lot of things from you. And you still have to help me spank that big sister of mine if I'm still weaker than her when we meet.'

They can all feel minute shaking throughout the training ground as Kisuke smashes the floor with his fist like a baby throwing a tantrum. Since the floor or ground inside the barrier is also strengthened by the barrier, there are only shallow potholes created with Kisuke's monstrous tantrum.

Aika and Koneko saw Yoruichi do some kind of gesture on the surface of the barrier and a small entrance opened allowing her to come in.

'The barrier won't hold up for too long if he keeps rampaging like that. I have to divert his attention to me so he won't damage the barrier any further.' Yoruichi slowly walks towards Kisuke position and pointed her index finger to Kisuke to cast a Kidou, "Carriage of thunder, bridge of a spinning wheel. With light, divide this into six! Bakudou No. 61, Rikujoukourou (Six Rods of Prison Light)!"

Six thin, but wide beams of light appeared around the rampaging Kisuke and slammed his midsection holding him in place. Even though only his midsection was hit, he can't move his whole body and what he can only do is howl and shake. But Yoruichi knew that this wouldn't last long and she continued casting while pointing her palm towards the immobilize Kisuke, "Bakudou No. 62, Hyapporankan (Hundred Step Fence)!"

From Yoruichi's palm, a rod formed of energy is thrown towards Kisuke before it disintegrates into numerous short rods which impaled his limbs making it harder for him to move and sealing him further. Yoruichi wasn't satisfied so she used another Kidou, "Bakudou No. 63, Sajou Sabaku (Ethereal Binding Chain)!" Yoruichi closes her hand into a fist and calls forth yellow energy, taking a form of very thick rope, which binds the upper body of Kisuke.

Aika and Koneko who are watching from the distance are awestruck.

"That's magic!? That's so cool!" Aika eyes were shining forgetting the current situation.

"That's indeed magic. But like Kisuke-senpai's, Yoruichi's magic is also weird." Koneko commented when she saw Yoruichi's binding spells.

"Wierd? How weird?"

"I've seen others cast magic and each spell is accompanied by a magic circle which defines its logic. I never saw magic which doesn't need a magic circle aside from those simplest of spells, innate magic or bloodline magic. But what they are doing isn't any of those, I'm pretty sure."

"I don't really understand, but we'll also learn it right?"

"Yes. Kisuke-senpai already thought me some but I still can't do it."

"Look! Yoruichi-san isn't done yet." Aika interrupted Koneko's contemplation as she saw Yoruichi's new movements.

Yoruichi clasps her hands and started reciting another Kidou, "Walls of iron sand," five small yellow orbs with skinny tails emerge from between her clasped hands, "A priestly pagoda, glowing ironclad fireflies." The orbs move above Yoruichi's head before forming a circle of five. Raising her clasped hands above their head, Yoruichi slams them downward, sending the orbs into the ground, "Standing upright, silent to the end." As a bright light is generated in the sky above Kisuke, five tall and thick pillars, which are connected to each other by chains appeared, "Bakudou No. 75, Gochutekkan (Five-Pillared Iron Weights)!" Pinning Kisuke to the ground.
