Yoruichi landed on the ground and all of the lightning energy she has before already disappeared along with the sleeves of her clothes, "That was close!" Yoruichi just didn't expect that Katerea will take the suicide route when she's not even fatally injured or anywhere near that.
Kisuke jumped down from the room and walked beside Yoruichi, "That's too much... You didn't even leave a speck of dust..." Kisuke complained as he watches the remnants of the destruction still crackling with lightning.
"Well... What should I say... She's strangely durable that she reminded me of Askin Nakk Le Vaar... Maybe I do have some trauma regarding that guy." Yoruichi sighed, admitting her mistakes.
"My~. If someone like him is here, it'll really be annoying... and dangerous." Kisuke understood Yoruichi's feelings. Although she and he has experience going against strong opponents like Aizen, Askin Nakk Le Vaar is not a particularly good memory for both. He's the primary reason that they 'died', after all.
While the two are talking, Azazel approached them with a serious expression, "Kisuke... You do know that the power she just showed is on the Devil King level, right? Although a lot of beings are on that level or even stronger, most of them are leaders of their respective factions. And to top it off, you probably has similar abilities..."
Kisuke turned to Azazel and took out his white fan to cover half of his face, "I'm flattered, but I'm afraid that's just a gross overestimation. I'm just a humble cheap candy seller."
Azazel scratched his head in frustration, "So you're going to insist on that... Fine then. Let me get straight to the point. What is it that you want?" Azazel has a feeling that even if he didn't extend his invitation to him for this summit, he might have still barged in for all the ridiculous reasons he could think of. And with them showing what they can really do, he guessed that Kisuke is giving them a warning.
Kisuke smiled but it's different from all the smiles that Azazel saw from earlier, "I thank you for making it easier for me. To be honest, I don't have the guts to just lay down what I want with all these prominent people present."
'Bullshit! All you have are guts!' They all simultaneous thought.
Ignoring there apparent reactions to his words, Kisuke continued, "I only want two things. First is a free and fair exchange of information between me and the Three Factions and the second one is the removal of all surveillance placed on me and those around me... I don't have a hobby of exposing myself, you see? But before we talk further, I'll let you people deal with 'that' first. We won't be getting involved this time."
"What are you-" Before he could finish his question, Azazel suddenly felt a huge blow landing on his back and he was sent flying a few meters. He stood up and took a look at his assailant in white-winged armor, "Vali... Turning on me now?"
"W-what's going on?... Why is Vali attacking Azazel?" Issei mumbled. He then recalled Azazel's words earlier that there might be a spy among them, "I see... So he's part of the terrorists."
Azazel dusted his clothes and asked, "Mind telling me why you betrayed me, Vali?"
"Sorry, Azazel. These guys are just more fun." Vali replied.
"So the great Vanishing Dragon is submitting to Ophis?"
"Nah. Just cooperating. Ophis asked if I wanted to fight Asgard, and it seemed like a nice way to test my strength. I don't imagine you'd allow me to oppose Valhalla and the Earth Gods, right, Azazel?"
'This muscle head still thinks that I don't know what he really wants? But it seems that he's hellbent on getting revenge on his own... Some adjustments to my plan should keep him safe from certain beings...' While thinking of this, Azazel kept talking to him to make him not get any idea, "I did tell you to 'get stronger,' but I also said not to contribute to the Earth's destruction.
"Like I care. I just want to fight forever."
"Is that so?... Well, when I learned that Katerea and the old Devil King Faction had joined up with the Khaos Brigade, I had sneaking suspicion..."
"Wait... What does that mean?" Rias asked.
"I'm a half-breed born to a human mother and the grandson of an old Devil King."
"You've got old Devil King blood in you...?"
"Yes. I inherited that royal blood and my human side harbors the 'Vanishing Dragon.' If fate and miracles do exist on this earth, I'm the living proof of them." Flying higher up, Vali formally introduced himself to his rival, the Red Dragon, "My name is, Vali Lucifer. I bear the blood of the previous Lucifer."
'This kid still hasn't gotten over his inner Chuunibyou...' Azazel thought.

Kisuke and Yoruichi just watched the ongoing drama. They are already expecting Vali to betray Azazel since they already got the information from Kuroka. Though they didn't really think that he would do it openly.
Azazel explained to Issei that Vali is the strongest host of the Vanishing Dragon in history. While Vali just mocked Issei for being the weakest host for being a normal human from top to bottom before stepping in the Supernatural World.
But even then, Vali knew that Sacred Gears, especially the Red and White Dragons, doesn't get all of its strength from the host's physique and most of its latent power lies in the will of the user. So he got the idea of threatening Issei with killing his normal parents, which in response, angering Issei to the point of immediately entering into Balance Breaker.
The two clashed and Vali kept halving Issei's power while Issei kept doubling his to keep up with him. Although Vali has an overall advantage with his abilities, Issei has a trump card which is the Dragon Slayer Sword, Ascalon, he received earlier from Michael as a sign of goodwill to the Red Dragon Emperor.
Issei was able to catch Vali off-guard and destroyed his white scale mail. However, Vali only laughed out loud praising his rival and immediately recovering and reactivating his Balance Breaker.
Issei knew that he won't be able to last long due to the limits of the armlet that Azazel gave him and is troubled how he would defeat his opponent when he saw the blue gem that came from Vali's destroyed armor in the corner of his eyes, giving him a crazy idea.
Issei grabbed the blue gem and tried to infuse it to his Boosted Gear like what he did with the Ascalon. Vali on watch in amusement as he tried to fuse two completely opposite attributes. He's also disappointed that the Red Dragon would die this early and not from fighting the White Dragon, but by attempting the impossible.
Kisuke and Yoruichi also watched him closely and are ready to jump in if something goes wrong, "That crazy kid... Only Zaraki can match him." Yoruichi mumbled.
"...Let's see how it goes first. Just help me watch the condition of his soul." Kisuke replied to Yoruichi, 'It looks like he really has what it takes... I should invest in him.'
After screaming in pain, Issei was able to successfully steal his rival's power, but with the price of his lifespan. Vali and Albion are both dumbfounded that he actually succeeded, prompting Vali to take this fight more seriously.
Vali's next move is 'Half Dimension' where it halves everything within his reach, including sizes.
And when Azazel suggested that it'll halve even Rias' breast, Issei lost it... even more so than it did when being threatened with his parents.
With Issei's power doubling again and again beyond Vali's expectations, and add the usage of the stolen Divine Dividing, Issei beat the crap out of him for the second time.
Getting more excited, Vali now intends to go further before being interrupted by a new person arriving.
