( Yuuki's POV )
When I created the barrier around us, the other faction leaders became alert but did not panic, a wave of energy crashed against my barrier seconds later, but that wasn't a direct attack; those outside my barrier were frozen in place.
Immediately afterwards, countless magical circuits appeared, and a small group emerged from them. Using magic, they teleported the angels, devils, and fallen angels out of this place.
Teleportation magic was also being blocked; someone was trying to lock us up and isolate us, a grave mistake.
Yuuki: Who would be stupid enough to attack four factions at the same time?
Michael: They are all magicians, humans.
Azazel: If they carried out such a coordinated attack on this high-security meeting, it means there is a traitor in our ranks.
Sirzechs: But what method did they use to paralyze all our troops?
Rias: Gasper!
When Rias came to a realization, she shouted Gasper's name, and I agreed with that. It felt like his doing, but he wasn't a traitor. I don't believe he's capable of something like that.
Yuuki: Someone must be controlling his sacred gear, no problem Mikoto and Oriha will take care of that.
Mikoto and Oriha were not affected by Gasper's Gear because they were connected to me, so I immediately told them to head to the club building, I'm sure they won't take long to fix whatever was wrong there.
Yuuki: Don't worry Rias, I've already sent my guardians towards Gaspar and the others.
Azazel: I'm not doubting your people's ability, but things will go better if there's a distraction, Vali, why don't you go out there and clear up the sky?
Valí: Better than just sitting here waiting, they'll do for a good warm-up.
The boy Vali flew out of the room, and he activated his balance breaker, he covered himself with armor like Issei's but in white, because he was a white dragon obviously.
Those outside the building were just lackeys but the ease with which the White Emperor eliminated a wave of them showed his power, and I could sense that he was still hiding most of his power.
I knew better than anyone how much Issei had grown, but he couldn't go against someone like Vali yet, not without the proper motivation.
Yuuki: We should go out too, no reason to be locked up here.
We walked casually to the school entrance and I questioned the local leaders if they knew anything about who was carrying out this attack, because they were not using foreign powers.
Yuuki: Does anyone have information they'd like to share? If you're wondering, they're not the ones I'm looking for.
Azazel: I have my suspicions, a trusted spy has been investigating a dangerous group, but I'll have to confirm it's them.
Yuuki: Hmm, interesting.
If we wanted to know something about the enemy, someone of a higher level than a lackey would have to show up on the scene, and luckily we didn't have to wait because as soon as we left school, we were targeted by an attack that couldn't have come from a mere lackey.
A powerful energy attack took the form of a snake, and this time those who put up a barrier around us to block the attack were the leaders of the three factions.
???: Hmph, a barrier made by three opposing factions, that's something I didn't expect to see.
A voice full of arrogance echoed throughout the place, and then from another portal emerged a woman with dark skin and brown hair wearing glasses, clearly not a lackey, this woman was quickly recognized by the two demon kings.
Sirzechs: ...Katerea Leviathan.
Serafall: it can't be, what are you doing here?
Yuuki: Leviathan, you say? Judging by your tone, she must belong to the ancient Leviathan family. Are you here to reclaim your title?
Katerea: How insolent! That careless brat shouldn't be carrying the name Leviathan in the first place.
Katerea didn't hide her disdain for the girl with the same name as her; I barely knew Serafall, but she was someone I already considered a friend, so I couldn't let those words go unpunished.
I placed a hand on Serafall's head and she was confused by that gesture, without giving an explanation, I stepped forward and confronted Katerea.
Yuuki: Hey, watch your words. If you think you're so much better than Serafall, you'd better be prepared to prove it. Why don't you show me what you've got? I must admit I'm curious what a demon king-level individual can do.
I unleashed some of my power and Katerea instinctively trembled slightly. I slowly approached her as I further increased my power, but before the battle could begin, Azazel put his hand on my shoulder and stopped me.
Azazel: Hey, how about you let me take care of this?
I looked at Azazel for a second, then sighed and lowered my power, somewhat annoyed by the interruption.
Yuuki: Hey man, are you stealing my moment here?
Azazel: Sorry, sorry, but if you have a fight worse than the one with Kokabiel, half the city could disappear, plus there's something I want to try.
Yuuki: I wouldn't do that, but if you're going to ask me like that, then have fun.
I returned to where the others were, and as I walked, I realized that there were still many lackey wizards around us, I thought that was strange considering how strong Vali was.
Yuuki: Rias, Sona.
Rias & Sona: Yes Sensei.
Yuuki: You and your peerage take care of the wizards; don't let them interfere with Azazel.
The young devils jumped into action and, like their sensei, I also gave them the appropriate motivation.
Yuuki: Oh, and if for any reason you are defeated by these lackeys, I will triple the difficulty of your training.
The young devils trembled a little at my words, but now they were appropriately motivated.
