After pinning Aika to the boulder, Koneko, and Sakura wanted to rush towards Kisuke to stop him from doing anything further. But just as they take their first steps, Yoruichi blocked their way.

"Yoruichi..." Sakura furrowed her brows as she said her name.

"You're misunderstanding things here, Mom. Kisuke isn't trying to hurt Aika-chan." Yoruichi calmly said.

"Then what is he doing?" Sakura didn't back off and continued to ask.

"He's giving her the chance to control her abilities and increasing her latent potential," Yoruichi explained.

"A chance?" Sakura's brows furrowed deeper.

"Yes, just a chance." Yoruichi nodded.

"What if she failed?" Sakura's voice is now growing colder.

"She'll turn into a monster that can't think." But Yoruichi continued to look at her eyes and spoke calmly.

"Then what are you planning to do if that were to happen?" Sakura's aura is now flaring up, and some of her Demonic Powers are also leaking out.

"Confine her somewhere until Kisuke finds a way to reverse her transformation. And if that is not possible, then we'll kill her ourselves." As if she didn't notice her change, Yoruichi stated their plan without hesitation.

"You...!" Sakura was shocked at her words as she didn't think they are capable of initiating this kind of plan and can become so cold-hearted when it fails.

Obviously, the onlookers are also shocked by her words. Akeno is especially worried about Koneko, 'Are they going to do something similar to her!? No! This won't do! I have to stop her from coming here!'

Yoruichi ignored their reaction and smiled, "You misunderstand again. We wouldn't proceed to do this if Aika is in real danger. Although all of what I said is true, chances of that happening are very minimal."

Sakura looked at her eyes and can't tell if she's lying, but she can at least tell that Yoruichi is very confident with her words.

Sakura sighed after a few seconds of contemplating, "Haahh... I'll trust you two this time. Don't mess it up and put Aika in danger. Let's go, Koneko-chan. We'll watch from the sidelines."

Yoruichi's smile grew bigger and answered, "We won't mess up."

She then turned around and pulled out four knives with inscriptions and threw it to the four corners of their location encapsulating her and the rest inside a transparent blue barrier.

"This is...?" Sona asks in wonderment.

"A barrier just in case a battle broke out." Yoruichi found a seat and took it, taking out her yogurt to watch the upcoming show.

Everyone saw this and returned their attention to Aika who is still pinned in the boulder, but she's already trying to escape while letting animal-like growls. The white matter already formed a half bone mask on her face while her the iris of her eyes turned golden with black sclera.

"What's happening to her?" It was Akeno who ask this time.

"Well... To make it easier to understand, that's her power going out of control. If she can't control it before she completes her transformation, that will become permanent." Yoruichi answered her despite not liking her very much.

Outside the barrier, Kisuke is intently staring at Aika and her changes. He is constantly scanning her with his soul and see how will her Sacred Gear affect the formation of her Zanpakuto. And Kisuke was intrigued at what happened.

Aika's Sacred Gear absorbed the Zanpakuto while it is forming and went to its place to become the Shinigami's 'Zanpakuto'. Her Sacred Gear even helped her fuse her physical body and soul body to help facilitate and adapt to the Reiatsu-Ki mixture. When Kisuke saw this, he felt cheated, 'Just like that? What the hell am I doing with my time...'

Kisuke continued watching, and just as he expected, the Reiatsu-Ki consumed all the dragonic aura to strengthen itself.

Inside the barrier, Ophis is also watching this unfold, although not as much as Kisuke. She can only see that there are some unknown changes to the Sacred Gear that it is now using some kind of energy that she is not familiar with.

Ophis had another shock today when she noticed that the strange energy is slowly consuming the dragonic aura which includes her energy until it completely disappeared. She tried looking for her snake and control it but failed. Ophis looked at Kisuke and became curious about the man himself for the first time as he is the instigator of this event.

When the dragonic aura inside Aika was fully consumed, her Hollow side completely took over covering her upper body with white matter together with the newly forming Shihakusho.

"GRAAAHH!!!" Aika roared and successfully shook off her bindings, dropping herself to the ground.

"W-What is that!?" Sona shouted. Akeno and Sakura also has the same question running in their minds.

"Sona-chan... Have you ever heard of a human transforming like this?" Sakura asks.

"Never heard of it... Akeno-san, what about you?" Sona passed the question towards the last conscious outsider.

"I've studied a lot of things on various topics to help Rias but I've also never heard of it. Tsubaki-san, do you know something?" Akeno then turned to Tsubaki.

"I would have to disappoint all of you, but if it is about that, you should ask these two." Tsubaki then pointed to Yoruichi who is happily eating her fifth cup of yogurt and Koneko who is watching worriedly. Both of them looked at Tsubaki but didn't say anything. Sakura and Sona sighed as they won't be getting anything from them.

Kisuke finally made his move and held his palms away from himself, with their arms extended out to the sides, before clasping his hands together, with the fingers intertwined intricately, "Bakudo No. 99, Kin (Prohibition)."

An invisible force swiped Aika's arms towards her back and several black spiritual fabrics tied it up and impaling it with iron shafts.

Due to the sudden movement and strangely heavy fabrics and shafts, Aika fell to the ground groaning. But she didn't give up and tried to stand up again.

Kisuke knew that it wouldn't take long before she breaks it so he continued. He slammed his fingers into the ground and released white spiritual energy, "Bakudou No. 99 Bankin (Full Prohibition), Prologue - Halting Wraps."

White spiritual fabrics appeared around Aika and covered her from head to toe as she shouts towards Kisuke.

"Refrain - Serial Hundred Bolts." Several metal bolts suddenly appeared in front of Kisuke and launched towards Aika impaling different parts of her body.
