"Heh, is this your castle? Pretty good, huh?"

"Naturally. This is still the Duke Demon."

I had come to her castle in the demonic realm, guided by Berfene, who was so proud to stretch his chest.

Demonic decorations are everywhere, and the atmosphere is disastrous.

I'm sure it's a big, splendid castle, but I don't really want to live there.

Well, maybe it's easy for the devil to live in.

Not only that, of course, but vicious traps and demons are deployed, and yet the last dungeon of the game.

"Geez!?

"Why are you hooked on a trap?"

"Ugh, shut up! They change the trap placement regularly, so I can't remember!

Berfene screams as she pulls out the poison arrow that stabbed her in the butt.

I have tears in my eyes, but the damage doesn't seem right.

By the way, I am now turning into a demon with my (Transformation/Polar) skills as an example.

You won't find out you're human... but you don't see any other demons in the castle in the first place.

As I was going through the castle with that in mind, I finally encountered the First Devil.

"Welcome home, Master Berfene"

It was the blue-haired beauty demon who had bowed his head respectfully to say so.

She is dressed in menswear and that suits her long and pitiful face very well.

Men's Costume Beauty Kitteroo!!!

"Thank you for leaving me, Mirage."

And, Berfene throws words of labor.

The beautiful demon, called Mirage, has been praising me and then turning his blue eyes towards me.

"What about this one?

"This guy, uh... oh, my new family Karna!

No, why am I your family?

The other way around, the other way around.

Berfene hastily pounded his ear.

"Mirage is a butler who's been serving my house since my grandfather's day.... Oh, I can't tell you how I'm being enslaved by you."

"Ho, I mean, indirectly, I'm her husband. We need to make sure our minds and bodies understand that... guffaw"

"I knew I wasn't bringing a guy like this..."

"What are you talking about? You said you wanted territory, didn't you?

"I told you! Ho, you're really gonna get it back, aren't you?

When we were hissing and interacting like that, Mirage interrupted along with a cough called "hon."

"Dear Berfene, I have a report for you"

"Ho, report?

"The other day, Count Malkoki, under his umbrella, was disobeyed"

"What, even Malcolm!?

Berfene raised her screaming voice.

"I think I've been saddled under the Duke of Levia umbrella. This is the fifth rebellion with the title. Compared to our predecessors, our Duke family's sphere of power has now been reduced to less than two-thirds. It could be downgraded to the Marquis soon as it is."

"Ugh..."

In the demonic realm, they say the devil with his own territory will be given the title.

The position is then determined primarily according to the size of the territory.

He is the Baron, Viscount, Earl, Marquis, and Duke from below.

And not the title, but further above the Duke, it was the Demon King who reigned at the summit of the demonic kingdom.

Apparently, the Demon King's Realm occupies the majority of the western part of the demonic world, and he says he can follow a large number of title-bearing demons.

Secondly, they have six duchess in all, including Berfene.

Not only do they each rule a massive territory, but they also seem to put a large number of subordinate titled demons under their control.

The territory of Berfene was almost in the middle of the eastern part of the demonic world.

Although the disadvantage of the location is that it surrounds the three sides by other dukes, it has nevertheless long continued to boast the largest territory in the east, he said.

A large number of named title-bearing demons were also under its umbrella, he said.

But that's what's happening here these days, and successively the rebels show up and the power zone is instantly decreasing.

"I mean, it's all your fault!... because you call me on your own... and they poke me..."

"No, I don't really matter, do I? Your territory has been dwindling for hundreds of years before you became a lord, so whatever you think, it's a matter of your own ability."

"Ugh, shut up!? Don't you dare go in there and try not to think!

"... think about it."

For thousands of years in the demonic world, there has always been intense territorial strife, he said.

But contention is, of course, a huge burden for those who lose, as well as for those who win.

If you say that you have taken territory because of it, but your land and inhabitants are exhausted in a protracted battle, you also get little.

For that reason, how long has territorial strife in the demonic world evolved into something smart?

If you are a monster with a title, you must have a "base".

Even when invading, they say it's the only way to attack.

And you think you can get a whole territory if you just drop a base?

If you violate this rule and fight anywhere but base, they will turn the whole demonic world against their enemies.

The battle therefore only breaks out in a fairly limited place: only the strongholds of both factions.

I have succeeded in minimizing damage thanks to it.

"Rather, the devil is progressing better than man."

"Most of all, at the end of thousands of years of contested history, I finally settled into that form."

Anyway, in order to expand the territory, you just have to let the other titled strongholds fall.

"Was it the Duke of Levia? Well, let's just crush him from his base."

"Hey, you can't all of a sudden!? Jumping into a duke stronghold is a suicide!

If you ask me, do you think that the base of a title-bearing demon has become a super difficult dungeon almost without exception?

The same goes for this castle in Berfene, of course.

In other words, an absolutely advantageous home for the other person.

To attack the stronghold and win.

Are they second-class or do the same demons work together in triplets?

Apparently, they're going to need at least that much fighting power.

This means that if you attack the base of a demon of the same quality alone, you have no chance of winning first.

Besides, the greatest power for a title-bearing demon is himself.

He said if he attacked the enemy formation himself, his own formation would be thin, and in the meantime he could be attacked by other demons.

"I see."

"Did you get it? It's not as easy as you think to take your territory. Let's start with the lower titles…"

"All right, all right. All right, take me to Duke Levia and his base."

"You have no idea!?

"It's okay, it's okay."

"What's all right with you!?

"You just have to go and crush it and go home."

"... no, this guy... I was the idiot I expected..."

Berfene sitting with her head in her arms.

"Don't worry. What you said about the Duke is worth your while, right? Then easy victory, easy victory."

"I'm so annoyed with the way you put it!?
