"Don't get too nervous now. What I'm proposing is very simple. If something like that happens, then you all have to take out the big guns without holding back and release it at the same time." And while it seems really simple, Aika thought that she has to mention it to them or they'll just become an unorganized mob trying to attack the big boss out of panic and hurry, 'And while they are at it, I try to find a chance myself...' "With that said, you know what to do with your abilities, right, Hyoudou-kun?"

"...Yes. I'll charge my Boosted Gear and transfer it to either Buchou or Akeno-san." Issei knew his limitation and his actual utility in this fight. Ddraig also brought up an offer that can power him up but it takes quite an amount of price, and even then, he probably still won't be able to repel Kokabiel.

"Good." Aika nodded in satisfaction and turned to Rias, "I'm sorry for taking your role, Gremory-senpai. I just have to do it since I saw you people charging in without much thought."

Rias shook her head, "No. It's okay. On the contrary, I'm grateful. It's thanks to you that I realized that I still have a lot to work on."

Aika nodded at her and faced Koneko, "And one last thing... I don't have to warn you, right?"

Koneko knew what she's talking about. It's about the use of her Senjutsu. She's still in the middle of healing her wounds so she can't use without risking her own life. She only nodded in response.

"..." Aika knew that if it comes down to it, she won't be able to stop her, 'This is a lot harder than I thought! Who brought the last boss here anyway!? A newbie like me isn't prepared!' Closing her eyes, she emptied her mind for a few seconds, 'I have to kill.'

Yoruichi and Kisuke already warned her about her, being a normal human not long ago, not having an experience of killing someone and the dangers of hesitating to do so when needed. They intended for Koneko and Aika to kill someone to at least experience it once but this situation came up abruptly that they haven't done it. Though Yoruichi gave them a workaround, and that is self-hypnotism. It's only effective on the first few uses and is intended for beginners who are very hesitant about killing. The withdrawal effects are worse than just getting a kill for the first time but one can get used to it too like normal.

All of them noticed Aika's sudden change in the aura and shuddered as she is now giving a very cold and indifferent demeanor. Koneko called out to them to explain what is happening, "It's a certain technique that Yoruichi-san taught us so that we, who haven't killed before, can unhesitantly kill if needed."

Everyone gulped audibly and Rias released a fake cough, "Ahem... Let's go. We don't want Kokabiel to rampage around just because we're late." And off they go.

"Azazel, Kokabiel already made his move." A handsome young man with light silver hair and light blue eyes, wearing a dark green V-neck shirt with a high-collared black leather jacket over it. He also wears burgundy jeans with a silver chain drooping down over them and black leather chaps with three bands encircling his right calf, and black shoes with black buckles. He is currently watching what is currently happening on the schoolyard from a distant building with a white magic circle in front of him showing a hologram of a certain man.

"It seems so..." The man on the hologram sighed. He is a tall man appearing to be in his twenties with an average build, black hair, golden bangs, and black goatee. He is wearing a V-neck maroon long-coat with a wide, open high-collar that opens up at the hem. The long-coat also featured two black belts around the waist and four black bands on each arm, two of the bands at the wrist and the other two near the elbow.

"Do you want me to step in now?" The young man asked.

"Not yet. Don't you want to see what your 'rival' is capable of, Vali?" The man called Azazel chuckled.

"I was so excited when I heard the news about the appearance of the Boosted Gear... But looking at him now, it's a huge disappointment. He's just a normal kid not long ago. I shouldn't have put any expectations." Vali clicked his tongue as he and Azazel watch the Gremory and Sitri heiresses meet.

"Don't be like that. You of all people should know that you shouldn't underestimate a Longinus possessor regardless of his race and way of life. You never know, his will might be equal or stronger than yours and if that is the case, even if it's just a fraction of a second, he might overpower you."

It was Vali's turn to chuckle, "If that's really the case, then I really want to see it."

Azazel sighed at his adopted son's addiction to battles. They watch the two peerages plan for things and it was relatively normal when they were given a shock. A very normal human girl suddenly appeared near them, "!?"

"Vali... Did you notice her?" Azazel only has visuals on his side but he trusted Vali's senses and instincts as one of the strongest members of his organization.

"...No." Vali's expression became serious.

"Maybe you didn't notice her due to her being very 'normal'?"

"Even then, I would have noticed her before she can even come near them..."

"..." Azazel only put on a thinking expression and a glint flashed through his eyes in a brief moment, "How about the White Dragon Emperor? Did he notice anything?"

From Vali's back, a voice as deep as Ddraig's resounded, "Yes... I already noticed her since earlier. She has been going around that facility prior to her contact with those Devil kids."

"!?" They were given another shock as Vali has been surveying around Kokabiel's position and didn't notice the 'normal' human girl walking around which is suppose to be unconsciously repelled by the large magic field in the area. And the fact that she's talking normally and even reprimanding the Devils due to their foolish actions of taking on things outside of their abilities clearly suggests that she isn't normal at all despite the 'normal' human aura she's giving off.

"What's up with her, Albion?" Vali asked.

"I only noticed her because she's supposed to be a normal human but she's walking around everyone being unnoticed. And what's different about her is that she has a Sacred Gear."

"Sacred Gear?" Vali somehow already guessed the situation, "So it's her Sacred Gear's ability."

"You're wrong."

Azazel and Vali became puzzled at his words and Albion continued speaking, "When I said different, I mean her Sacred Gear is 'dead'."

Vali became even more confused while Azazel's eyes widened in shock, " 'Dead'? You mean there's a spirit in that girl's Sacred Gear but it's already dead?"

"That's all I can say... The red bastard over there might have some more answers as he's closer in proximity."

Azazel thought for a few moments before muttering, "Interesting..."
