Kisuke and Yoruichi only came back late in the afternoon and everyone welcomed them. Although they didn't expect that they would come back this late.

However, once they got close, they noticed something about Yoruichi. In particular, her jolly mood and glossy skin.

Aika, suspicious of this, suddenly asked, "Did you enjoy it?"

Everyone didn't know why Aika would ask that kind of question. Of course, they would enjoy each other's company and there's no need to ask such a question.

Yoruichi, however, displayed a big grin, "I enjoyed it more than I thought. Apparently, doing it outside really feels different. We didn't have to clean the mess we made too as we can just cover it with dirt."

"...You damned perverts..." Aika could only mutter such words with a twitching mouth.

Everyone didn't know what they're talking about until Aika called them perverts. The two cat sisters could only react the same as Aika, while the other two only blushed slightly.

"Let's not stay here and get inside. I have a lot of things to talk about." Kisuke then pushed Yoruichi and prompted the others to follow.

Since it's already late, they decided to have an early dinner and while everyone is eating, Kisuke started to talk about his experience in that city and his findings.

"I see... So the intelligent species are humanoid..." Yoruichi muttered.

"And there are a lot of races living together such as humans, elves, and beast people." Aika did the same.

"A fantasy world in the medieval period... And a technology that centers around magic tools..." Sona followed.

"What about those that look like humans but aren't, nya?" Kuroka asked.

"I also don't know much about them but luckily, their language is easy to learn due to some amazing coincidence that I didn't notice earlier and I managed to pick up some sort of maybe history books from the library that I visited."

"What coincidence?" Sona curiously asked.

Instead of answering her, Kisuke took out his modified smartphone and on the screen, it displayed one of the pages he got from the book in the form of a hologram.

Sure enough, they didn't know what's written on it, except for one person, "Is this... Latin? But there are some differences like how the way they're written. However, it's still mostly the same from what I know. Kisuke... could this be...?"

"Yup~! This world's language~. Well, at least in that city. Amazing, right?"

"No, no, no! That's not just some amazing coincidence! What's this!?" Sona couldn't understand how Kisuke could describe this just as a mere coincidence.

"Even if it's not a coincidence, we don't have time or manpower to investigate the origin of this world's language and even by doing so, it won't help us much so just think of it as a 'mere coincidence'."

Sona stared at Kisuke blankly for a few seconds before sighing, "Haah... You're right... I'm sorry for interrupting you. Please continue."

Nodding at her, Kisuke continued, "The written language is Latin and the spoken language is some weird mix between English and Latin with some pronunciation sounding different. I didn't notice it at first since I already marked their language in my mind as something entirely different. I clearly failed in that regard."

Kisuke stopped for a moment to look at everyone, but seeing that they don't have much reaction, he continued, "Once I figured this out, several names were mentioned in between the people's words such as 'Loki', 'Freya', 'Hephaestus', 'Ganesha' and more."

"Norse, Greek, and Hindu Mythology, huh... Is it this world's religion?" Yoruichi asked.

"Well... Sort of... These Gods, however, isn't some unseen being by the masses. These Gods descended from Heaven and is currently living with the mortals by leading their so-called 'Familia'. If my guesses were correct, these guys who look likes humans were Gods in the mortal plane. And there's a lot of them."

"So Gods are walking on earth? It feels like we're in ancient times. Do they nurture heroes too or wage wars like the stories in our world?" Medusa joined their conversation as she's very interested in the topics of Gods.

"They do something similar. These Gods give their blessings to mortals and these mortals would fight monsters to strengthened the blessings they received, or something like that, based on my understanding of all these texts."

Yoruichi instantly caught Kisuke words, "Blessings... you say... Did you find the answer to our problem now?"

Kisuke smiled at her, "Probably... But I would need to do some more stalking if I want to confirm this. With that, I'm leaving again tomorrow morning to continue my investigation and refine the decoded language. This time, I would like to stay there for five days before coming back... That reminds me, Yoruichi, Aika. Don't use any of your techniques with Reiatsu-Ki unless you can contain any resulting energy release to the surroundings as these guys seem to be very sensitive to it. I almost got caught because I carelessly scanned the surrounding with my Reiatsu-Ki."

"Got it. I'll be careful." Aika answered while Yoruichi nodded at him and asked, "Is magic fine?"

"Yep. Just not so much. We don't want to attract attention when we still don't have any foothold."

"Uhmm... Kisuke... There seems to be some problem with my magic." Sona then caught everyone's attention.

"Hmm? What is it?" Kisuke's expression became serious.

Sona nodded at him and arranged her thoughts before speaking, "Although I can recover normally by converting this world's Mana to Demonic Power, I can't do anything beyond it.

"I can use my magic fine if I use my Demonic Power, but when I tried to actively gather Mana to recover, the Mana suddenly became very volatile that I had to stop. After discovering that, I tried to control the Mana directly by moving it slightly according to my will, but it took me several minutes just to do that. And as you can guess, the Mana also becomes volatile when directly controlled."

Instead of speaking, Kisuke, Yoruichi, Kuroka, and Medusa directly tried to test the Mana in the surroundings.

The four of them who tested it was able to control it with Kisuke and Yoruichi the fastest who was able to do it, "Indeed... This is a lot harder..."

"It's not just a lot-nya! It's a hundred times harder-nya! We won't be able to use magic properly once we're depleted!" Kuroka corrected Kisuke.

"That's not right either, Kuroka-san... You shouldn't be able to use magic properly with Mana depleted... Please don't adapt their common sense." Sona then corrected Kuroka's statement.

"Ah..." Kuroka held her head and started reflecting, "What's happening to me...? That's right... It shouldn't even be possible to use magic without Mana reserve in your body... But these guys are directly controlling the Mana in the atmosphere to cast their magic if they're out of Mana... When the hell did I start thinking that it's a normal thing?"

Ignoring Kuroka's 'crisis', Kisuke issued them his plan, "All right, here's what we should do. I will go to that city again tomorrow and while I'm out, you girls will be practicing how to control this Mana. I know it'll be hard, but it isn't possible. If you're already confident about your control, try absorbing some Mana into your body or casting some simple magic first to test it out. And that includes you, Koneko and Aika as you can't use the techniques that Yoruichi and I taught to you. Any questions?"

"None." Everyone except for Kuroka, who's still mulling over her common sense, answered.

"Alright~! Dismissed!" Kisuke then walked towards Kuroka without wasting any time and grabbed her by the waist and started carrying her over to her room.

Kuroka immediately snapped back to her senses and asked in a panic, "W-wait! W-what are you going to do, nya!"

"Something you want me to do," Kisuke answered simply.

Kuroka's mind finally caught up and understood what he's planning, "Please wait a moment! I'm not ready yet, nya!"

"Then get ready within five seconds."

"That's impossible, nya! At least let me set back my common sense, nya!"

'So that's what she's worried about...' Everyone thought as Kisuke closes the door to Kuroka's room. A second later, Kisuke put up a sound dampening barrier but if you're close enough, you'll still be able to hear what's happening inside.

Curious about it, Aika, Koneko, Medusa, and Sona approached the room and put their ears on the wall. A minute later, they finally heard Kuroka's moan of ecstasy, "Ahhnn~♡! M-more~♡! Here... This place~♡! Ahnnn~~♡!"

They immediately went away with hot faces but they are all thinking of the same thing, 'It's just a minute and all of her shame is already gone.'
