It's been a few days since Kaori learned about the other world. We've continued to study for tests since then, but one thing has changed between us. That was Kaori's wish to study at the house in the other world.
It's not that Kaori doesn't like the house in Japan, but she says the air in the other world is better, so studying there will help her clear her head. Well, now that the existence of the other world has been exposed, there is no particular reason for me to refuse it, so we study in the other world.
And along with that, I showed Kaori some dishes made with ingredients from the other world, and she was happy to eat them.
By the way, the ingredients I used were a type of food that increases our status. Although Kaori's status has increased thanks to those ingredients, apparently she didn't get the experience value from that group battle with the [Hell Slime], so her level is still at 1.
…I don't really understand this concept of experience value either.
Normally, it wouldn't be possible to experience being attacked by a group of slimes like that, but that experience doesn't add to the experience value either. Assuming the means of gaining experience is that you have to fight and win directly, that's pretty much impossible.
Fortunately for me, thanks to Sage-san's weapon, I was able to beat a hundred times stronger monsters when I was at a low level and low status, and I realized once again that I was truly blessed.
However, that Sage-san's weapon is exclusive to me, or rather, it's been contracted at some point, so I can't lend it out, and if Kaori wants to level up, she'll have to find a low-status monster. Or rather, I don't think the experience of killing a creature is a good one, so I'd like her to stay calm if possible…
However, despite being level 1, thanks to the status-raising ingredients in my house's garden that increased her status a bit, Kaori has a superhuman physical ability on Earth.
It seems that when she got home, she was able to carry a heavy load with ease, which surprised even Kaori herself… but I told her to keep that matter to herself. Well, I haven't been able to hide it well myself, so it's a bit late to say that.
Just like that, we were still taking a break after finishing our studies at the house in the other world.
"Hmm! As I thought, the air in this world is really good!"
"Yeah. You get used to it when you're over here, but when you come back to Earth, things get a little weird."
"Ah, I know! What can I say? It feels a little smoky."
We talk to each other about the other world's air and smile, and Kaori starts to soften up after a bit.
"Hmm? What's going on?"
"Eh? Ah, no, you see…"
Kaori was a bit hesitant about something, but she immediately looked at me with a determined expression.
"Yuuya-san, would you be willing to show me around this world?"
"Eh?"
When my eyes widened at the words I hadn't expected, Kaori looked straight at me.
"It's partly because I want to know more about this world, but I also want to see the things that Yuuya-san has seen in this world."
"That's…"
"Is that bad…?"
"Ugh…"
I stifle my words to Kaori, who looks up at me anxiously.
…If I think about it, that's true. If you come to this unknown world, you'll want to look around.
It's just…
"…It's difficult, I guess."
"Why is that…?"
"Just like Kaori was attacked before, there are a lot of monsters in this world. And even if you go to the city, it's not as safe as in Japan."
Even in the royal capital, there are those who have been caught up in raids, and there is even a disturbing organization called the Dark Guild.
"I want to take you with me, but I'm not strong enough to say that I can absolutely protect you."
"Are you still not strong enough, Yuuya-san?"
"Yeah, I'm not quite there yet."
Master Rabbit, the mysterious girl from the other day, there are many opponents I can't compete with anyway. And that's exactly the case with the monsters in the depths of this great devil's nest; I won't be able to fight them properly with the current me.
Kaori heard my explanation, and her mouth was somewhat aggrieved.
"Mmm… If that's the case, then it can't be helped…"
"I'm so sorry."
"…But then, if you think it's okay, Yuuya-san, will you take me with you?"
"Of course!"
"Then, I forgive you."
Kaori gave a slight smile as she said that.
"So, we might not be able to go outside, but it's okay inside this house's garden, right?"
"Oh, that's okay."
"Then let's go to the garden!"
Responding to Kaori's request, we go out into the garden.
"Once again, I think outside; it's a strange place. The trees around it are also of a type I've never seen before… Come to think of it, what do you grow in that field?"
"It's a vegetable from the other world that I made Kaori eat the other day, and it has the effect of increasing the stats. Of course, it doesn't rise without limit, but I thought it would be a good idea for Kaori, who has trouble raising her level."
"I was really surprised when I got home! Well, I was convinced later when I heard the reason… but then again, it's hard to keep a low profile, but it's a little funny to think that I have the power to be like a character in a story."
"I'd appreciate it if you put it that way. Also, I'm growing a medicinal herb called [Complete Recovery Herb], but…"
"Medicinal herb… is it?"
"Yeah. What's amazing is that these herbs can heal any wound."
"What kind of wounds?"
"Yeah. For example, even if you lose your arm due to some accident, if you take this [Complete Recovery Herb], that arm will grow back."
"G-grow…"
Kaori's face paled a bit as she imagined the scene. I wasn't anything like that since fighting monsters in this world became the norm for me to slash off hands and such, but it would normally be a pretty shocking image.
"And then it does not just heal wounds; it seems to heal diseases as well. Maybe it can heal anything except resurrecting the dead."
"….."
Kaori was at a loss for words when she heard the [Complete Recovery Herb] explanation.
"…If such a thing really existed, I think everyone would seek it out… And if there is that herb, it can cure incurable diseases that are still considered incurable all over the world today. Right?"
"Well…"
"It's a complete fight-or-flight effect on Earth's medical technology…"
Indeed, when I think about it, [Complete Recovery Herb] is a blown effect. I've already tried not to think too much about it just because it's something that Sage-san was growing.
Besides, I need to prepare a lot of recovery methods because it would be troublesome if something happened in this world or in the exploration of this great devil's nest.
As I was thinking like that, Kaori was staring at the field with some kind of difficult expression.
"That… Yuuya-san. I'm sure Yuuya-san already understands enough… but obviously the crops, concepts, and items here are too dangerous on Earth."
"…Yeah."
"The spear in and out of empty space the other day was also unique to this world, wasn't it?"
"Yes. It's a skill called [Item Box], but…"
"I don't know how much of that skill can be stored, but if it were unlimited, it would overturn all common sense on Earth."
"….."
"I also think that the power of magic is a very dangerous thing. If this power is known to Japan and the rest of the world… it would not be a good thing."
If Kaori is right, if the concept of this world's magic were brought to Earth, it would be only a matter of time before it was used for warfare. And as Lexia-san said before, teleportation magic is definitely one of the most dangerous types of magic.
For me, I can easily go far away and stop being late to school, but I don't want to use it for the extent of that, but that's not the case if I think about it on a nationwide basis.
It's really hard to keep up with this world.
"…I think we're done for the moment, and we should go back."
It was then that Kaori was about to go back to the room… with a wry smile as the conversation turned out to be more difficult than expected.
"──Yuuyaaa-samaaaa!"
"Eh?"
I let out a shout of surprise and turned around to look at…
"It's me! Here!"
"How do we expect to survive if you keep making us do things your way! Shit! Any number of lives wouldn't be enough for Lexia's guards…!"
"Aah, my head hurts…"
To my surprise, I saw Lexia-san blasting towards this house, and from behind her, Luna and Owen-san jumped in to fight against the monsters that were following further behind them, desperately. Apparently, it seems that the ones chasing after Lexia-san and the others are a group of [Goblin Elite].
"Uhm…?"
Kaori stares at me, bewildered by such a scene, and I stare back at Kaori like that. Then Luna notices me in such a state.
"Ah, hey! Yuuya! Help us! …wait, who's that woman next to you…?"
"No, I think we have bigger problems right now. We're in danger of becoming the monsters' food for thought if we're not careful."
"You will be the sole prey, Owen! I'm busy now!
"It really makes me sick to my stomach…! Kuh! For that matter, I can only hold the entire goblin elite back as best I can…!"
"That's what I'm doing! Complain to the stupid princess over there!"
As usual, I mean, Owen-san looks like he's having a very hard time. Is he going to be okay? I'll give him some Earth-grown stomach pills and headache pills next time. As I was looking at the scene in front of me in a daze, thinking that I'll have to go to the pharmacy next time, Lexia-san noticed me too and raised her voice.
"Yuuya-samaaaaa! Who's the woman next to youuuuu!"
"…Eh, Yuuya-san? Those people are…?"
I couldn't help but look up at the sky as I realized that this was going to be complicated.
"Ah… well, can I head over to help first?"
"Eh? Ah, yeah, I know. It sounds like it's going to be pretty tough…"
"Thanks… Night, Akatsuki. I'm sure it will be fine, but just in case, watch over Kaori."
"Woof!"
"Fugo!"
While laughing at their energetic replies, I quickly changed into my [Bloody War Demon Series] armor and ran off at once.
"Phew!"
Then, with the least amount of movement, I released a kick to the forehead of the goblin elite that was closest to Lexia-san, and the face of the goblin elite exploded from the force of the kick.
Without killing the momentum, this time, I stepped through the head of the Goblin Elite in Luna's direction, and then I used that leg as an axis to slam a spinning kick into the Goblin Elite that was closing in on Owen-san.
Until now, I wasn't able to move this smoothly, but thanks to my training with Master Usagi, I was able to attack like this while smoothly moving on to the next move when it came to kicks.
The number of Goblin Elites had decreased with my participation in the fight, and Luna and Owen-san had also successfully defeated the Goblin Elites they were dealing with.
When all the Goblin Elites were thus eradicated, Owen-san took a breath.
"Phew… Yuuya-dono, thank you for saving us."
"N-no, that's fine, but… well, what exactly is going on…? You went all the way to such a dangerous place…"
There is no longer any need for me to go to the royal capital, so there shouldn't be any need to come all the way to the dangerous great devil's nest like this. Then, as if realizing my inner feelings, Luna looks at me in a dumbfounded way.
"What is it, Yuuya? The other day, Lexia said she was going to visit Yuuya's house. Or are we not allowed to come unless we have something to do?"
"Eh? No, it's not like that, but…"
"Then that's good. It was Lexia who started it, but I… Uhm… I've wanted to meet you too."
Seeing Luna's cheeks redden as she says that, I remember being kissed by Luna before, and even I get red in the face. I ask Luna as if to disguise such an expression.
"C-come to think of it, how did you get here? It must have been hard for you."
"Yeah… but Lexia's selfishness means that we have become a little stronger too."
"I-I see…"
I couldn't help but give a drawn-out smile at Luna's somewhat accomplished reaction, and Luna pointed in a direction.
"More importantly… that, can we leave that alone?"
"Eh?"
When I turned my gaze toward the… direction Luna indicated, I saw the figure of Lexia-san, who had crossed the fence and entered the garden before I knew it, silently confronted Kaori… W-what was that atmosphere…
As I hurriedly returned to my house with Owen-san and the others, Lexia-san and Kaori didn't seem to care about us and continued to stare at each other in silence.
"….."
"….."
I'm not sure what to do with the too heavy atmosphere, so I looked towards Owen-san to ask for help, but he seemed to have his eyes closed and didn't give a damn about it. W-well, he's usually having a hard time…
Next, I turn my attention to Luna, but for some reason, Luna is staring at me with half-lidded eyes. Eh, why?
No one seemed to be able to do anything about the situation anywhere I looked, and when I was in full-blown trouble, Lexia-san slowly opened her mouth.
"…You, what's your name?"
"…I'm Kaori Houjou. Uhm… you are?" [T/n: Wasn't Kaori didn't have the language comprehension skill?]
"…I'm Lexia von Alceria. I see… if you don't know me, then you're from the same country as Yuuya-sama…"
As I watched the course of events to see what would happen once they knew each other's names, they suddenly turned their gaze towards me.
"By the way, Yuuya-san──."
"By the way, Yuuya-sama──."
"What is your relationship with this person?" they said in unison.
