Everyone except for Sona is already awake and Kisuke made more food for them, "How are you feeling? Are you feeling any discomfort?"
"Nothing wrong with me, master," Medusa answered first.
"I'm fine nya. How about you, Shirone?" Kuroka followed.
"I'm fine too... But..." Koneko answered but hesitated and looked at Aika.
Aika nodded at her and continued her words, "It feels slightly heavy for us. I thought it was just my imagination at first, but it seems that Koneko is experiencing it too."
Kisuke furrowed his brows, "Please stand to the side, you two. I'd like to take a closer look at you."
Following his instructions, Aika and Koneko stood to the side and waited for Kisuke. Kisuke approached them and touched both of their foreheads to send a wave of his Reiatsu-Ki to both of them.
After a minute or two of examinations, Kisuke's brows further furrowed, "I can't see anything wrong..."
"Looks like you first have to set up some proper facilities for examinations before everything else," Yoruichi commented. Both her and Kisuke knew that now they're in a new world, even the slightest discomfort could prove fatal, especially when there is no apparent evidence of the discomfort.
"You're right... I should..." Kisuke nodded seriously.
"Where are we anyway? I took a peek outside and saw that was surrounded by forest." Aika asked.
Kisuke sat down and said, "Another world." And drank his tea calmly.
"Another world?" The four of them asked, "We're in the Underworld-nya?" Kuroka continued.
Kisuke shook his head.
"If we're not in the Underworld, then some other realm-nya? Where exactly? And aren't we in danger of being discovered if we're out in open-nya?"
Kisuke still shook his head.
"...What are you trying to say-nya?"
"We're not in the Human Realm, the Underworld, or any other realm..."
"...What-nya?"
"When I said another world, what I mean is that we're on a world in a different universe from ours."
"...What!?" Everyone exclaimed, "Hey... You expect us to believe that?" Aika still couldn't believe it.
"You'll know in a few days of staying here."
"The hell..." Aika and everyone knew that Kisuke doesn't have a reason to lie about this and they could discover the truth on their own, "What? We're we summoned to become heroes and defeat the demon lord? That's cliche!"
"And what will you do if that's the case?"
Aika's eyes gleamed and she exclaimed, "Of course escape from the trashy King and find the loli Demon Lord to pamper her!"
"That's cliche!" Kisuke retorted.
"I love cliches!" Aika answered with all of her confidence.
Kisuke only chuckled in her response and continued, "Well, we're not summoned. We came here because Yoruichi's power got out of control and drilled a hole through the Dimensional Gap, letting us land in this place."
"What? So we're not even sure if there is an intelligent being here?"
"No. We spotted a city before we came to this forest so there should be an established civilization."
"Then let's go there now!" Aika excitedly suggested.
"No. We have problems that we have to solve before we could even approach or live in that city. First is we have to confirm that their appearance isn't very far from us."
"I see... If they're quadrupedal, then we would have to live that way too if we want to stay there... Moreover, what if they're not humanoid? Then we can only stay away from them..." Aika muttered.
"Correct... Next is we have to adjust our microbiome first before we could make contact. The last thing we want is to bring unknown diseases to the innocent inhabitants of this world from us, invaders."
Everyone nodded as they understood Kisuke's point.
"Then assuming that we can blend with the inhabitants of this world and can make contact with them, we still have a problem which is the language and cultural barrier. As for the culture and common sense, it could be easily learned but before we could learn that, we first have to master their language."
Kuroka then raised her hand, "What about the Devils' and Angels' innate skill, 'Language'-nya? Wouldn't that work?"
Kisuke shook his head and explained why, "Devils' and Angels' existences are connected to their believers, which are the humans. So it's only natural for them to instinctively know the language of their believers. Obviously, it won't work in this world where there not a single believer present."
"I see-nya... So our only choice is to learn the language-nya? How long would that take-nya? Especially when we don't have anything to reference their language-nya? And you're not thinking of staying here for a few years just to learn and decode their language-nya, right?" Kuroka asked worriedly.
"We have to learn their language, but it won't take that long to learn it. Besides, I'm the only one who needs to actually learn it."
"What do you mean?" This time, it's Yoruichi who asked him a question.
"I learned how the innate skill 'Language' works so I also know how to directly insert a language skill into someone's mind. And I don't think it would take that long for me to learn a language as the environment is almost the same as our world."
"...R-right... I remembered when you learned Greek up to speaking level in just a single night... Looks like we're in good hands..." Yoruichi's mouth twitches as she remembered that one instance that Kisuke suddenly talked in Greek.
Aika then suddenly grabbed Kisuke's arms and said, "Sensei! No... Master! Please teach me English!"
"After we return home. So behave for now."
"Yes!"
Kisuke then proceeds to ignore Aika, "Where are we? Right... The problems. For now, those are the problems that I can see. There will be more in the future if we want to return but let's focus on that for now.
"Then the schedule, for now, is everyone's recovery and microbiome adjustments with my help and after that, training to adjust your bodies in this world's atmosphere.
"While you do that, I'll be sneaking in that city to gather information. Any questions?"
"Will you be going alone, master?" Medusa asked.
"Yep. I can move easier with me alone."
"But that's still dangerous. We don't know what's out there."
"Don't worry. I won't go in without any preparations."
With that, Kisuke ended the meeting and let everyone rest again.

Three days later, Kisuke finally discovered the problem of their world transfer, and it isn't a small one, "The world itself is rejecting us..."
