Silence engulfed the room as they look at him with different expressions and the first one to talk is Serafall, "Ki-tan... What was that?"
In response, Kisuke just smiled at her, "Hmmm? Who knows~?" He then turned to Azazel and changed the subject, "By the way, Azazel-san. It seems that you knew a great deal about this terrorist, Do you mind sharing your knowledge to us here so that we can understand a bit of the situation?"
Azazel stared at his smiling face for a while before sighing, "Haah..." Shaking his head, he thought, 'No way he's gonna just answer that.' He then faced the other leaders and stated a name, "Khaos Brigade."
Sirzechs knew that he won't be getting anything out of Kisuke so he turned his attention to Azazel, "Khaos Brigade?"
"I only recently learned the organization's name and background. They're gathering dangerous members from each of the Three Factions. And I confirmed that they've already got a number of Balance Breaker and Longinus users." Azazel narrated.
"What are they after?" Michael asked.
"Ruin and chaos. They've no interest in the peace on Earth. Nasty bunch of terrorists. and their leader is-" Azazel words were interrupted when a magic circle appeared on the corner of the room and a voice of a woman came from it and finished his sentence, "Ouroboros Dragon, Ophis."
"That crest!... I see. These terrorists' string-puller is..." Sirzechs instantly recognized the crest on the magic circle and gritted his teeth, 'Does that mean the rest of the Old-Satan Faction is also in this Khaos Brigade?'
From the magic circle, a tall bespectacled woman with a voluptuous figure. She had tan skin with long brown hair tied into a bun with a headset and she had purple eyes. She wore an extremely low-cut dress and it had a high slit which exposed a large portion of her breasts, "Greetings, current Devil King Sirzechs-dono. I am Katerea Leviathan, kin to the previous Leviathan."
"A relative of the previous Devil King? The millennia of fighting have left Devils on the ropes. The very species faces extinction if another war breaks out... But those with the blood of the old Devil Kings were determined to keep fighting. From what I heard from Onee-sama, they were chased into the shadows of the Underworld." Sona explained to Kisuke and Yoruichi.
Katerea smiled hearing her, "The majority of us Devil King descendants have decided to cooperate with Ophis and the Khaos Brigade."
Azazel's expression didn't change at her appearance as if he's already expecting her, "I never imagined you all would join Ophis committing these acts of terror."
Katerea started releasing her Demonic Power and laughed, "As a symbol of power himself, he's perfectly suited to bring different powers together. And by that power, this world will be destroyed and then rebuilt. We will be the ones to rule over that new world!"
Azazel's response to her words is just a sneer, "So Ophis is your patron, then?"
The innocent Serafall couldn't stop herself from speaking anymore and asked, "Katerea-san! Why are you doing this!?"
Katerea glared at Serafall with apparent hate, "A shameless question, Serafall. You're the one who stole the Leviathan title from me! Today is the day I kill you and become the rightful Devil King Leviathan! This world is rotten and needs to change! So when Ophis becomes the God of the new world, we will create a system that governs it! Your era has come to end!"
"Pfft! Look at that Kisuke! This is gold! Someone actually says that in real life? Just because things don't go her way, she'll blame the world for it! That's just a loser's thought!" Within the serious atmosphere, Yoruichi's voice resounded.
Kisuke nodded at her in agreement and commented on his own with a serious expression, "Right! Only hormonal teenagers and people who already gave up on themselves can have that kind of thinking! It's just like those people who can't win in a game of chess and just choose to flip the board over!"
After hearing their words, Azazel started laughing out loud and added a comment of his own, "Ahahaha! That's really it! She sounds like a villain from a B-rated movie and the first villain who dies!"
Katerea instantly lost in when she heard them, "How dare you mock me!" Flaring up her Demonic Powers, she turned to two unknown humans who're strangely in this room where the summit is held, "Who are you!?"
Yoruichi ignored her and faced the leaders, "Hey, how about leaving her to me?"
The four leaders looked at each other. They also wanted to see the power of the mysterious human and they all agreed. But before agreeing with her, Sirzechs first asked Katerea, "I don't suppose you'll surrender, Katerea?"
Katerea ignored him and kept glaring at the two humans and took out her weapon, a wand, "Haah!? Someone like you!? Didn't you hear what they just call me!? I'm the descendant of the late Devil King Leviathan!"
Sirzechs sigh and signaled Yoruichi that she can go.
"Great~." Yoruichi smiled and stretched her limbs for a bit.
"Are you listening!? How dare you go against me when you just a measly hum-!?"
Yoruichi didn't let her finish her words and used Flash Step to instantly appear in front of Katerea and sent a kick towards her face. The kick connected without her being able to react and the force behind it sent her flying away outside, destroying the wall on her way, "You talk too much."
"..."
"Well then, I'll be going first~!" Yoruichi waved her hand towards Kisuke before jumping off the window to follow the still flying Katerea.
"Hey... Sirzechs, Serafall, Michael..."
" " "Hmm?" " "
"Did any of you catch that?"
The three leaders shook their heads at Azazel's question.
"How the hell did we miss something like these two?" Azazel asked again.
"...Well, there are still a lot of things that we haven't discovered yet in the world. And those two are one of those. But one thing is for sure... We shouldn't make them our enemies. It'll be a lot dangerous if someone like that can move around us." Sirzechs muttered to the other three and his maid.
"Haah..." With a sigh, Azazel proposed, "Let's go outside first and clean those things."
Everyone nodded in agreement and started exiting the room through the whole that Katerea made.
The last one to get out is Serafall and she looked back only to see Kisuke is still not moving from his position and just watching everyone, "Aren't you coming?"
"Nah~. I'm too tired already. I'll just be here to rest and cheer for you. Besides, you probably won't need me there."
"I see... Then rest well." Serafall went out after saying such.
Kisuke sat down on the chair and just watch his lover have fun with the Devil. However, he still a bit worried so he sent her a telepathic message, 'Yoruichi, that woman has Ophis-chan's powers. You better not let your guard down.'
'I know. I wouldn't want to be killed by that adorable humanoid dragon's power.'
