"Hey, you're home. So how did you do, little girl? How was your tour of earth?

"Yes!　Very nice place!　Touching, seeing, and tasting all sorts of unfamiliar things, things that just don't exist in the world I was in!　If possible, I would love to bring our culture back to my world!

Haha, well, you can do as much about that as you can. But do it in moderation. If you try to bring in too much of our culture and speed up the evolution, the result could be dangerous.

"More importantly, Dad. Let's get on with it. Why did you put me back in this world?　Also, explain to me what's going on with my dad.

　I'm going to ask him again, while holding back Fitis, who is happy to report back to her father.
　I've neglected to ask him who he is, or why he was in that world, and so on. It's about time you told us. I mean, just explain.

I guess so. First of all, I was one of those who were accidentally transported to another world. I was about 15 at the time and I was sent to that world.

　Considering my father's age, that's about twenty years ago.
　So there have been cross-world transitions before that.
　But if you think about it, that's true. Even in anime and manga, there have been many transitions to other worlds before that.

But the reason I moved to that world was because the goddess called me.

"To Moe?

"Oh yeah.

　Oh. But why again?

"I'm with you on that. For the evolution of the world. You wanted to use an outside force, an alien, to facilitate it.

　I see.

So, did my dad help you with that?

Well, indirectly. I met my mother at that destination. By the way, your image at that time was quite different from now. Even though it was the order of the goddess, she was quite unsettled by the fact that we demons were prepared to evolve human beings and that we were hired by them to do so.

　I almost asked myself if that was so, but now that I think about it, it's only natural.
　As for Lily and Behemoth, they accepted their roles and were rather ready to dedicate themselves to the evolution of the world.
　However, this is an act of self-sacrifice, akin to a human pillar.
　Even if SS-ranked demons were created just for that purpose, not everyone would accept them.
　Mom's dilemma is natural.

She hated humanity at that time. Well, he treated me coldly too, hahahaha.

　The old man laughing and talking about his past encounters.
　He was what would be called a "tsundere" nowadays, and while he was coldly criticized many times, he and his friend, a girl called witch, gradually melted Mom's misanthropic feelings, and before he knew it, Dad and Mom had become attracted to each other.
　That's a classic otherworldly romance from somewhere.

So what happened after that?

Yeah, well, I got caught up in a battle with the then Demon King. After that, my mom and I were sent to this Earth.

　How long have you been flying?　I mean, what was the Demon King back then?
　Don't be so quick to foreshadow what's to come!

And then you had me in this world and went back to the other side with your mother?

I know, but do you really think you can just pompously walk across an alternate universe like that?　Don't you think that's God's domain in a way?

　Well, that's what I thought.

"Originally, this ability was not mine, but that of Semargul, the Goddess's entourage.

"Oh, that goddess guardian

Yes, she gave me the ability to cross over to another world so that my mother and I could be sent back to Earth.

　So that's what happened.
　I mean, it's been a while since I've seen that guy's name.

　Semargul. He was the young Seemurgle, the SS-ranked demon who came for me at the goddess's. He must have been Locke's father.
　You know, I've still left Locke in the other world, is he alright?
　It's already been more than half a day, and if this is the case, I might be left behind for more than a day.
　While I was worried about this, my dad laughed as if it was no problem.

"Don't worry, Kyou. The ability to cross the different worlds that Semargle gave me can also manipulate time. I'm sure you'll be able to see that it's only been an hour since you moved from here to there.

"Huh?　How can you do that?

Oh, it's not so much an ability to cross over to another world. It's more of a creation skill to create 'space-time'.

　The Creation skill of Space-Time. Another one of those grandiose skill names.

In other words, manipulate and create time and space. I'm traveling across the other world because I'm creating a space between this one and that one. When I do this, I can manipulate time, so that when I get to the other side, decades may have passed, or conversely, only a minute or so has passed.



　I see. That explains the mystery of where my father had been.
　And I also figured out why it's definitely been more than half a year since I went to the other world, but in the world I came back from, it's only been three months or so.

"That's an amazing ability, Dad. Is it possible to go back in time?

　I'd rather be jealous. Give me that skill.

"Well, that's something I can't do. Semargle's original owner might be able to manipulate time like that, but I was just given it, so I can't do that. The first time I used this ability, it took me a while to get used to it. When I returned to the other side with my mom, more than a hundred years had passed, and she was appointed as the Demon King right after that.

　Nah, I see. If you don't handle it well, hundreds of years will pass when you move.
　Scary, but it's a good thing it was on the move from here to there: .......
　If it were the other way around, it would have been all over the place and my dad and I would have never seen each other again. .......
　I'd like to have one, but the disadvantages are too great for me to get used to, so I'll pass.

And here's the thing. When I came back, my mother and I did something that the goddess asked us to do. She said that one day I would summon you to that other world as a grown man.

"Yes?

　Then my name came out of nowhere and I was surprised.
　Why me?

I told you in the beginning. I told you that I was indirectly responsible for the evolution of that world. That he hooked up with your mother and gave birth to you.

What do you mean by that?

　I heard a line I've heard in a comic book somewhere, and my dad replied to it.

When I went into the other world, I had a creation skill. I had a creation skill when I went into the other world.

"Demon change?

"Think of it as the ability to control the direction of a demon's evolution. I could show the monster's evolutionary change for the better, or encourage it to evolve into something else entirely. Using this ability, I succeeded in cultivating a thing in that world. Can you understand what I'm saying?

　When he said that and explained his skills to me, it reminded me of something he used to do in that world.

Oh, yeah, vegetables!　I didn't know my dad could make vegetables because of his skills!

"That's it. I turned the demons into vegetables and made them grow. But I could only control those demons as they evolved and grew. I didn't have the ability to create and grow the monsters themselves.

　In short, Dad's ability is like a breeding program.
　He could take an existing thing and improve it into something edible or better.
　But he couldn't create the original thing itself.

But born between my blood and my mother, an SS-ranked demon, you were born with skills that literally surpassed my skills, and that's exactly what--

"Demonology skills, you mean.

　I breathed a sigh of admiration when I heard that much.
　Until now I thought there was no reason for me to move to that world.
　And moreover, I thought that the ability to create demons in a world where there were only demons was just a coincidence.

　But that was not the case.
　Everything was predestined to be this way before I was born.
　I don't call it the bloodline of a legendary hero, but my transition to that world, this skill, and the role I played in evolving the world were all planned before that, from my father's stage.

　I'm interested in the grand plan of my dad and the goddess, and at the same time, it's a mystery to me.
　I didn't think I was worth that much.

That's why. That's why you were called into that world from the very beginning, isn't it?

　So that's what happened.
　I've heard this much about my dad, and I'm pretty sure I know what he's talking about.
　So, there's only one thing he said before coming here about the evolution of my skills: .......

I'm sure you're a perceptive person and you're already aware of that.　Yes, you have my blood in your veins, which means--

"You think some of my demon cultivation skills should include the ability to evolve and improve my dad's demons?

　My father laughs at my words as if they were the right answer.

That's right. I'll show you the details tomorrow, so you can get a clue. It's time to get confident, Kyoji. Your ability to grow demons is a skill that will allow you to continue to perform feats that no one else has ever been able to do.

　Although I was somewhat embarrassed by this unusual compliment from my dad, I didn't feel bad about it.

　At first, I was just trying to survive or live a slow life, but now I realized that this skill has been nurtured by many more people and goddesses than I had expected.
