After their respective reunions, everyone sat down while Medusa prepared all the snacks and tea, "Mind explaining everything now, Kisuke?" Yoruichi started.

After clearing his throat, he told everyone about his adventures on Earth and gave them the reason why he brought other people with him. Of course, he didn't tell them any sensitive information for now as it won't be any use to them. Although he planned to tell Yoruichi everything he knew later.

"I see," Yoruichi nodded in understanding and looked towards Akeno and Irina with a grin, "So they wanted to come, huh?"

While Irina whistled poorly and looked around in an attempt to ignore her piercing stare, Akeno just quietly sipped on her tea before saying, "I already said it. After all those things he had done, I won't let go of him easily."

Chuckling, Yoruichi acknowledged her words, "Got it. It's for 'revenge', is it? You're free to mess with this guy if you can."

"I certainly will~," getting some of her confidence and 'anger' back after remembering what she experienced in Kisuke's hands, Akeno replied.

Yoruichi then turned her attention back to the 'prime chaos-bringer', "Are you sure you didn't intend for any of that to happen? Thanks to Great Red's appearance, even the Gods are panicking. Hestia almost cried when I told her it's your doing, you know."

"I promise you it is not. Though I would have really loved to see her expression," Kisuke shook his head, "By the way, what's the situation after I left? Surely, a God or two went after you, after that incident."

Yoruichi sighed after hearing that and placed her hand over her forehead, "Haaahh... It's troublesome! After you left, Freya herself intercepted our return! Though she wasn't able to get anything out of it because Hermes is keeping his word, I can always see her scouts in the corner of my eyes."

"As a safety measure, I asked Sona, Aika, and Koneko not to go on their own outside because they're the ones gathering people's attention and I figured Freya would want to start with them. There are other annoying Familias trying to recruit us, but it's not that hard to fend them off," And as if remembering something, Yoruichi added, "Ah, though there is one of them who is particularly tiresome."

"Ah, you mean the Apollo Familia?" Aika asked.

"Yeah. That one. While they haven't done anything forcefully, I have a feeling they'll do something sooner or later. But we don't really have to mind them as Kuroka or Medusa by themselves can wipe out their whole Familia."

Kisuke, however, just grinned, "Well, if they do try something, it's fine to bring them to a stage and show a bit of force. That should also stop some unsavory eyes from keeping a watch and bring Hestia-sama's name some glory."

"Hmmm... Let's talk about that when it actually happens. For now," "Uhmm, excuse me." Irina interrupted Yoruichi, "But what are these Familias you're talking about?"

Aika and Koneko then proceeded to explain the concept of Familia, Gods, and the Dungeon to Akeno and Irina. Meanwhile, since the unreasonably clingy Devil King won't listen to anyone but Sona, she's forced to say the same thing to her older sister.

Once they got the basic rundown of the 'rules' of this world, Serafall immediately stopped bothering Sona and entered her so-called business-mode, "So people in this place get stronger by signing a contract with a God and being granted this Falna? Although on a much larger scale, isn't this like the Evil Piece System?"

Kisuke nodded, "Correct. But instead of a High-Class Devil, the one powering the development and giving their strength is a God. By gathering 'Excelia', the Adventurers can exchange this to gain more power or knowledge."

"However, unlike Devils who can learn what they want, develop themselves to the future they want or create magic or technique based on their understanding, the strength that is granted to the Adventurers is based on their qualities and actions. Aside from that, it was automatically obtained so the Adventurers could only use what's given to them and entirely give up on creating their own techniques and spells."

Kisuke then shrugged his shoulders, "Of course, although these systems look pretty similar, the underlying foundation and mechanics are very different. While the Evil Piece System primarily works on physiques, Falna mainly works on the souls. And not just that. Even with its apparent limitations, Falna is a much more mature and complicated system. After all, even with my expertise, I can't tell the full extent of its abilities."

Serafall nodded. Thanks to Kisuke's simple explanation, Serafall was able to easily understand it, "So I assume that you lot already have this Falna, right?"

"Ho? You can tell?"

"Of course. The moment we reached this world, I immediately checked a few things. One of which is the movement of Magic Power. Compared to us, who came here for the first time, your Magic Power is properly attuned to the surrounding while ours became chaotic."

Kisuke's eyes widened, 'She can tell that much? This proves that her magic sensitivity is way beyond mine. After all, I can't tell what exactly is amiss when we first came here. She's a Devil King, alright,' He then smiled at her, "Correct. To be accepted by the world, we have to come under its prominent system or else it'll treat us as intruders and we don't want to know what's going to happen if we reached that point."

"I see... So where do I sign up?"

Yoruichi sighed, "Our patron God is currently busy because of your unconventional and controversial ride. But she should be able to return before dinner. We'll introduce you girls to her later."

Kisuke then took out two containers of candies and placed them on the table, "But before anything else, take one of each of these."

Serafall grabbed the yellow candy and examined it, "What's this?"

"That one will adjust your microbiome so that you won't infect residents of this world and vise versa. The green one, meanwhile, will directly inscribe language knowledge to your minds. With these two, you'll be ready to interact with others. By the way, Ophis-chan, you just have to take the green one, though I don't know if it'll work properly on you, so you have to make adjustments yourself."

Ophis nodded and directly took the language candy and savored its taste in her mouth while analyzing the information hidden in it and taking it for herself.

"Heh? So it's not as simple as sudden world travel, huh?" commented Serafall and directly took two of them at the same time.

Akeno, Irina and Claire also followed suit and the group continued talking about the things that had happened in both worlds until Hestia and Artemis returned from the Denatus.
