The Legendary Rebuilding of a World by a Realist Demon King

-side eve-

The diary of Ashtarot's army maid. A few weeks after giving birth to Demon King Ashtaroth.

I was summoned for my master in the knowledge of this world, but it was a series of surprises since I was born.

The master quickly adapted to this world, despite having no knowledge of the world.

He has been as if he were in this world since he was born.

Its elegant appearance is a female demon who lives in this castle, especially the succubus, which has a good reputation, and one that aims to be the lover of the master.

You need to strengthen the security of your husband's bed.

The master keeps being surprised, but what is the most surprising thing is his knowledge?

The master,-Demon King Ashtaroth was the weakest of the 72 Demon Kings. However, a week later he was out of the worst. He attacked the adjacent Demon King's treasure house and expanded his army at once. The trick was too bright. First, pretend to be respectful to the neighboring country, Count Islamia. Then he asks for help by performing his subordinate act. Ambush Sabnak's headquarters while fighting the two. I was so beautiful that my subordinates lost their words.

After that, the master also rejected the revenge battle of the angry Demon King Savannak, and on the contrary he returned.

Is there a Demon King who killed another Demon King within one month of birth besides his master?

In my memory called the walking database, there is no other than such a demon king and master.

When the master defeats the Demon King Sabnak, he immediately takes action. Dispatch troops and seize the castle of the Demon King Savannak, stealing materials and treasures there. And without hesitation he destroyed the castle.

Usually, if you take another's castle, you want to keep it and protect it, but the master declared in a cold voice:

"I can't defend both castles with my current strength. I'll destroy this castle. It won't be occupied by other demon kings or humans."

Some demons complained about it, but the master relented.

"I don't want a stone castle or a town. The people who live there are the property. So the people who live under the castle of this subnak castle I get."

Hearing the words, I and all other savvy demons were impressed. Toshizo Hijikata is also surprised at the amount. Normally, the people who live in the castle town of Demon Castle find value only as workers.

Class In each demon's castle, demons, humans, sub-humans, beastmen, and various types of humans live, but are fixed and exploited by the demon king.

In particular, it was customary for residents of other cities that had just been captured to be treated as synonymous with slaves, but the master treated Savannak inhabitants the same as their current inhabitants.

They were forcibly relocated to Ashtaroth Castle, but did not confiscate their possessions and settled on their status.

In other words, there are no slaves under the castle of Ashtaroth Castle. This was an exception among the 72 Demon Kings. No, not even a human city. I was curiously ruled and visited one day.

"Master, why don't you make yourself a slave?"

The master who asked so said with a slightly troubled face.

"... I don't think it's pathetic, because this castle is run by tax revenues earned from working, though they are all commoners."

"And for profit?"

"Yes, that would be the most comfortable. There was slaves in the world where I lived before, but slavery was inefficient. I won't go up. "

"……So that's it"

"I eat from their work, but I work more than them, and I think it's my job to provide them with a comfortable place to work."

The master who affirmed it was relentless to deserve respect. Involuntarily leaking such lines.

"In order to embody that ideal, I want to serve my husband in this life."

The master who heard the words smiled and said, "I'll ask you for your help."
