[Ah! Don't run! Sona already knows that you three secretly went back in!] Nyx dived back to her shadow and disappeared without any trace as if she didn't exist in the first place.
"...That was?" Loki asked Riveria.
"...A security guard." Riveria briefly answered.
"No way I'll believe you." Loki instantly retorted.
But before Riveria could explain, Issei interrupted them, "Riveria-san, we will be going first."
"Please be careful and see you later."
Issei nodded in goodbye and both him and Vali summoned their Scale Mails before flying off towards the administration building where the center command of the current operation is being held.

When they reached the cafeteria, the food was automatically prepared and everyone just had to get a tray for themselves. Since there were around two hundred people, the Deities and their leading children set their own table with Ouranos asking Lyd, the lizardman, to represent the Xenos group.
Everyone was tired, but thanks to the delicious food that just mysteriously appeared, almost everyone ate in silence, including the Deities that actually needed to sustain themselves now, though not to the same degree as the mortals.
After filling their bellies, it was finally time to talk, "Ahh~ I'm satisfied and I want to lay down... But I don't think I would be able to get a wink of sleep without knowing what just happened." Loki started and turned to Riveria, "Us asking questions would be incredibly inefficient so just tell us the whole story."
"Hmmm... Where do I start?" With all eyes on her, Riveria began thinking about what she should actually tell since there's no way for them to fully understand her without stepping into that world and experiencing it themselves.
"The moment you went to their 'hometown'," Gareth suggested.
As he requested, Riveria started her story the moment she was brought to Earth, a place that is so much more diverse than the current one. She colorfully described the Earth and its various cultures and advancements in technology. And as she expected, not all of them were able to wrap their heads around the scale of the other world in various aspects, including their daily lives.
Even then, Riveria's words captured everyone's imagination and no one interrupted her. The only one that could fully process her story was Freya, who possessed bits of Kisuke's memories.
Finally, Riveria reached the main course of the meal, "Moving on, there are many powers that exist in the other world and peace only really exists on the surface. One such power is the Ouroboros Academy, which consists of people who have close relations with the Belial House of the Underworld where Kisuke originates."
"Since it'll be hard to explain the number of factions that could influence the world, I'll only be talking about those who came here."
"First of all, one of the largest factions in that world is the Devil Faction which can be considered as a nation, of a race known as the Devils. You've already seen a Devil since Sona is one of them. Their most striking characteristic is their Devil Wings and the higher the number of pairs there are, the stronger one is."
For the first time since Riveria's storytelling began, Kali interrupted by raising her hand, "Please speak, Kali-sama."
"Are you referring to the one that Serafall tackled? She has five pairs of wings, how strong is she?"
"Those with five pairs of wings are considered to be at the top. Although not quite on the level of a God yet, a Devil with ten wings is able to directly fight a God to a certain extent." Riveria, however, didn't tell them that there are individuals that can't be measured by that world's own metric due to them possessing abilities that goes beyond that could be considered unique. And the greatest example of this Riveria herself, only able to manifest eight wings.
'Right, I have to tell them that I'm a Devil now too.'
"And how many people like her are on that side?"
"I have no idea if I were to include every faction but if it's just the Devil Faction, around a hundred? Though that's not really what's terrifying but the amount of soldiers they have."
"How much?"
"Millions. With the weakest the equivalent of a Level 3 or 4 and the strongest around the same level as a top tier Adventurer or Mercenary."
The children stopped drinking their beverages and a chill went down their spine as they imagined an enormous army with individuals as strong as them.
"Are we going to get that much support!?" Ganesha hurriedly stood up and asked. Even though each soldier is just as strong as their children, with enough numbers, it'll be an unstoppable force that even Gods would fear.
But the one who answered her was Loki, "No way that would be the case. And a country with that amount of soldiers would be very large and a large country like that would be bound to have its own problems regarding the spread of authority and power."
Riveria nodded, "It's as Loki has said. The Underworld is very large. Even if you multiply this world's population several times over, the country of Devils will still have more. Due to that, the nation is divided into 72 Pillars with the council of Elders and 4 Devil Kings standing on top."
A familiar term instantly tickled some of the Deities' ears, "...Devil King?" Loki muttered.
"The Elders of the council came from 72 Pillars and this Elders would elect 4 Devil Kings that would lead all the Devils." Riveria further explained, "And yes, Serafall is one of the Devil Kings."
The Deities went quiet. It was only now that they realized that Serafall's standing might have been higher than them all this time. It now became understandable why she didn't care whether they're Gods or not, especially for her patron Goddess, Artemis.
"Enough of the Devil Kings since they are not really relevant to this operation. I haven't confirmed it yet but looking at the people who came here, this is all made possible by three houses of the 72 Pillars, namely Belial House, Sitri House, and Gremory House, and the agreement from Team DxD."
"...Sitri... Sona Sitri..." Freya muttered to herself, "She the daughter of this noble house? And it was mentioned that she's Serafall's little sister so she's technically a princess?"
"She's the current heir to the House of Sitri... But I think she's going to pass that position soon to someone down the line."
Freya couldn't help but smile and said, "Because of Kisuke, right?"
Riveria nodded, "Kisuke doesn't have any intention of inheriting any position. But currently, he and I belong to the House of Belial." As she said those, Riveria thought, 'Because he's already a powerhouse on his own with influence in various organizations that couldn't be measured. He's the biggest wild card on that side and that's the reason why many don't like him.'
"You and him? So these Pillars also accept outsiders into their ranks?" Loki asked and was not really thinking about it deeply.
"Not really. You could only join one if you're a Devil without any affiliation or you marry one of its members."
Immediately, all eyes went wide as they stare at Riveria, "You're married!?" Lefiya shouted from the end of the table.
Riveria knew that this question would pop up and immediately answered, "No." But what happened next caused more shock when she insinuated that she married Kisuke. Four pairs of deep black Devil Wings suddenly emerged from her lower back, "I fulfilled the first condition."
