- King of Demons Capital, "Rage Giheg"

Me and Nell, who temporarily left Leila and arrived there on an airship, were reunited with the Demon King.

"Hey, Yuki. It's been about a month. It's been a long time since you've been brave."

In one of the discourse rooms in the Royal Castle of the Demonic Realm, the King of the Demonic Realm Final calls out with his usual sneering smile.

"Ooh, Demon King. You look good."

"We're out of time, Demon King"

"I heard you guys were coming, but I didn't know you were coming with the airship. How was it, that ship?

"Oh, it was fun. Airways are great because they're fast."

"Sorry, it's a product, but we got on..."

Final laughs and answers Nell, who looks a little sorry.

"Hahaha, no, no, I'm not going to be as narrow as complaining about that. I'm going to use it as a transport ship."

"It would help if you could say that. Are you going to develop an airship over here in the future?

"Right, the advantage of something called an airship was known in that war. It has long been known that there are strong flying races, but with humans gaining new means of flight, technological competition will enter a new dimension. Hey, people who can work their brains out because they don't have an advantage in the flesh, they're still strong. It's good to be able to strengthen the connection in that war."

Well, I agree.

Humans are weak. Therefore, work wisdom to survive.

Even in previous life, that's how man became the ruler of the world.

The Demon King pleasantly says so, then goes on with the words as if he remembered.

"Yes, Yuki. I need someone to see you."

"Someone you want me to meet?

The Demon King has a belly-black grin, and when he speaks outside the room, "Come," he opens the door and a man enters.

Soitz, I know him well, too...

"Become - this, the emperor!?

"What... Emperor?

"Long time no see, Demon King. You seem to be doing very well, above all."

Coming in was the former Emperor of the Logardo Empire (...) - Schendra-Gandru-Logald.

Next to Nell, who doesn't seem to understand, I open my mouth in disgust.

"Oh, you, you're dead..."

I hear he was executed in order to put an end to the future scourge.

It would be a lie to say I had nowhere to think about it, but it was this man who actually waged the war, so I was wondering if I had no choice about that either...

"Huh, ah. I'm a dead man now." Shen, "not the emperor Shendra-Gandr-Logald, but just a researcher under the Demonic Realm King. Instead of offering all the knowledge I know, you're free to study. Absolutely, a man of greed."

"No, no, Shen, your sell-in was pretty good, too. It's too late to look at your lab and crush that talent, so if you want to swallow these conditions, I thought you'd be engaged in research."

Between the belly blacks, the horses seem to fit in somehow, two people laughing at each other with a nigga.

... Apparently, he decided to save the former emperor by exchanging some conditions.

By the way, the captain and crew of the airship are not here.

They are currently selling their airships admirably to demonic engineers, perhaps explaining how to operate them.

I'm supposed to break up with them in this Demon King's Capital, so I'll have to go and thank you later.

"... well. I won't say anything if you're comfortable with me. Good for you, too."

"Oh, it's great to leave the troublesome task of governance and the like to others, so that they can do whatever they want and live. After all, I seem to have been a root researcher."

Much more lively face than before, the previous emperor who spoke so.

Something is going to make me happy.

"... you, you could have said a lot to the person who entrusted you with the troublesome job?

"Oh, I left it to those who deserve it. Proper material would be good, wouldn't it?

He answers that all the time, hoisting the end of his mouth.

... At all, he who reigns as a 'king' is always trying to be fat.

This man is no longer an emperor, but he still seems to have just served it.

When I'm smiling bitterly, he keeps saying things.

"More than that, Demon King. I'm doing some research on the dungeon right now. I wanted to talk to you a little bit about it."

"! Heh... well, I'm interested too"

Answering that, the former emperor asks me with a researcher-like face.

"Demon King, what do you think is a dungeon?

"... that's a tough question. I know it's a different kind of creature than we are."

"Oh, that's right. That kind of consciousness poured in from the dungeon when I also gained authority as Demon King. Perhaps… one rank is higher than ours (...) creatures"

Top of the ranks, huh?

Sure, maybe you can say that.

The dungeons are powerful.

That is enough to make it possible to create the world and organisms as well.

There is no doubt that there is another difference between what we know about 'organisms'.

"The dungeon works so that its administrator, the Demon King, extends nature and the dominant realm, but it is only natural for organisms to strengthen themselves to win the competition for survival. In these respects, we can say that we have a biological ecology that we know well."

"Ah. You've chosen the path to survival by strengthening the Demon King and symbiosis, haven't you?

The former emperor snorts.

"That's the thing. It's just... there's one thing I've always thought of about something called a dungeon."

That's what he prefaced and said.

"I think - isn't this world where everything is (...) one dungeon (...)?
