"Do you have a better way?" Grayfia furrowed her brows and asked her.

"I don't!" Yoruichi answered proudly.

The ever so serious maid's mouth twitched, "Then why did you interrupt us?"

"Because Kisuke can do something about it!" The proud cat jumped on top of Kisuke's head and displayed her smuggest expression at Grayfia.

Grayfia's twitching mouth worsen, 'Is she looking down on me? And why is she the proud one?'

"Ehh~? So I'm really the one doing the work?" Kisuke scratched his head, "If you're bored, why don't you just play with those magicians outside?"

Yoruichi looked down and explained to herself, "You know me... I hate grinding mobs! I'll only move for boss fights!"

Getting impatient since they are already running out of time, Grayfia urges them, "If you can do something, then please do it now. If not, please don't interrupt us."

Sirzechs wanted to stop her, but he can feel his maid's frustration and just choose to watch from the sidelines.

"Haahh... Fine... Gremory-san, please bring everyone from your group and get ready."

"Everyone? Are you sure?" Rias asked in confusion. Even with the help of her big brother, who is a Devil King, and his 'Queen', they can only bring one more person due to restrictions and that is using 'Castling' which is a convenient method.

"Yep~." Kisuke was about to don his Hollow mask but stopped first to warn everyone, "I'm injured and my aura control as of now is shitty so please beware as it might go wildly~."

"Even if you release your aura, the only people you can scare are the youngsters. The rest where veterans of war so you don't need to worry." Grayfia replied. She trying to tell that he won't affect the leaders and her so his warning is useless.

However, the only people who knew what he really can do is Serafall, Azazel, and Vali. So they stayed quiet and braced themselves.

"Is that so~? Then please excuse me~!" Putting his hand over his face, he swiped over it and a white bone mask with green marking appeared.

'!!!?'

However, due to a piece of his soul missing, Kisuke wasn't able to fully control his Hollow powers, so at the same time that the mask appeared, his Reiatsu-Ki exploded outwards and a heavy pressure engulfed everyone.

The pressure is so heavy, everyone, except for the four leaders and Grayfia, were instantly pushed to the ground as if the gravity increased multiple times.

The leaders wanted to help them, but they couldn't move carelessly as they needed to watch the person who is emitting this kind of malevolent aura. However, they still released their own auras to offset Kisuke's aura lightening up the load on the youngsters.

But not only them were shocked as both Yoruichi and Kisuke were surprised at this result too. The first one to move is Yoruichi as she transformed into her human form and immediately cast a binding spell, "Bakudou #61: Rikujoukourou (Six Rods of Light Prison)!"

Six thin, but wide beams of lights appeared around the unmoving Kisuke and slammed into his waist holding him in place.

Yoruichi watched the quiet Kisuke carefully and noticed that the Reiatsu-Ki that he's releasing is already easing up until some of it is only present, "You okay now?"

Kisuke looked up with his mask on and spoke with overlapping voices, "Yeah... I'm fine now. But that was a mistake..."

Yoruichi sighed in relief, "Whew... You did say that your control won't be what it used to after creating that Sacred Gear but I didn't know it would be this bad... You almost lost yourself back then."

"Right... Looks like I underestimated Benihime's control over the Hollow Powers..." Shaking his head, he started reflecting on his mistake that could have been disastrous to those around and himself, "Anyways, since I can only hold out for a few minutes with this, let's get this done..." Kisuke then looked back to others and saw their current states, "...Oops... My bad."

The young Devils, in addition to Irina, were lying on the floor breathing heavily. Vali is also kneeling on the floor a few seconds ago but he already stood up while looking at Kisuke with a bit of fear in his eyes.

Although nothing much happened on all the leaders plus Grayfia, they are warily looking at Kisuke with cold sweat on their backs. Although just for an instant, they glimpse of what seems to be Kisuke's true power, 'Can I win?' For the first time, Grayfia asked this to herself after witnessing that.

'So he's still holding back when he fought Kokabiel and Vali back then...' Serafall and Azazel thought as they recalled the much terrifying and heavy aura he released just now compared to the last time he put on that mask.

Kisuke first cast a soul-soothing Kidou to the young Devils and they all recovered and managed to stand up after a bit of difficulty. They all gave Kisuke varying expressions. While most of them are fear, Sona is giving him a resigned expression while shaking her head, 'This idiot really knows how to mess up.' Only she, who knows Kisuke better than anyone except Yoruichi, can understand that he didn't intend to do that. Sona only felt a bit of fear when he released his Reiatsu-Ki and all of it disappeared when he reigns in his aura, 'Is this an improvement?...' She asked herself as she looks around and observes others' expressions of fear and wariness, 'This much is needed if I want to stay with him.' While thinking such, Sona ended up smiling.

Sona's smile, however, didn't escape the notice of three leaders, Grayfia and Vali and they all thought, 'Is she crazy? How can she still smile?'

Serafall and Akeno also noticed her smile and the former could only blankly stare at her little sister's nerves, while the latter didn't know what she's feeling and could only grit her teeth in frustration.

Kisuke looked out and felt something. He then looked back to Rias and her peerage, "We don't have much time anymore so get going." Kisuke raised his hands and from his fingertip, the void split open like a jaw opening with accompanying static sound. From the other side, they could all see the hall of the old school building, 'Forcefully splitting the void in this restricted space!?' Those who understood what he just did were shocked again.

Yoruichi is staring at the standing still youngsters and urges them, "What are you waiting for? You have something you have to do and you should focus on that first."

Rias recovered from daydreaming and took a deep breath and led her peerage, "Everyone, let's go and save Gasper! We can't delay things anymore!"

"Yes, Buchou!" Issei, Asia, Yuuto, Xenovia, and Akeno then followed her and arrived at the other side of the split-open void.

After they went through, Kisuke immediately closed the void and removed his mask, "Whew~. I didn't expect it to be that tiring! I shouldn't have done it!"
