Cain, who became a frontier count and ruled over a territory other than Drintru, but in reality, life has not changed.
　It is not immediately handed over to you, but currently deputies and inspectors will be dispatched from the king's capital to investigate the current state of the city, and then Cain will take over after the results come in.

''It's going to be busy from now on: ......

　Duke Eric told me that the school was free to attend school, but I could see that if Cain didn't attend the school, Telestia and Silk would bend his navel.
　That's why I had made up my mind to attend school as much as possible.
　As I was thinking about this, I was in my office looking over some papers when there was a knock at the door.
　When I gave my permission, it was Lizabeth, accompanied by Dalmatia, who entered the room.
　Lizabeth sat down on the sofa and Dalmatia made a cup of tea and gently placed it in front of her.
　She brings the cup to her mouth and takes a huff and sighs before opening her mouth.

Cain, I think it's time for me to return to the country. It's comfortable here, and the food is good, so I'd like to stay here if I can. ...... You're right, you're going to cause trouble.

　Hearing those words, Cain stopped working once and took a seat across from Lizabeth.
　To be honest, one more Lizabeth wasn't much of an expense.
　He didn't particularly care for it as Dalmatia was caring and responsive and enjoying herself with Lula and Laura.
　However, it's been a good number of days since I came to this city from the Republic of Illustin.
　If you include living in the Republic of Illustin, you've been away from your own country for a long time.

'...... That's right. I'm sure your parents would be worried about you, and it would be better for you to go home for once.

　Lizabeth nodded lightly at Cain's words, but her expression seemed to bite down on a bitter worm.

...... That's the reason ......, I'd like you to go with me.

　And Dalmatia, who was standing behind her, also stepped forward and bowed deeply.

''Cain-sama, if you can, if you can help Lizabeth-sama, please help me: ......

　From Cain's point of view, Dalmatia had never before bowed her head like this and asked for a favor.
　That's why it was so uncomfortable.

''--May I ask you to tell me the details?

　Cain is not reluctant to go to the land of the demon race either.
　He also knows a demon king named Set. Although I've never visited Set's country, I have a desire to go there.
　Moreover, I know that I will be spending a busy time as a frontier count in the future, so I figured if I could go, it would be now or never.

I have to explain this to you. The reason why I left the country first of all is: ----

　It explains why he left the country from Lizabeth.
　He has a brother and an older brother, but he and his brother are not on good terms.
　They are the only two siblings, and one of them is supposed to take over the country, but the brother is planning to marry himself off with a demon king from another country in order to make it absolute for him to take over.
　Moreover, the person he wants to marry is quite a bit older and has several wives.
　He left the country because he didn't want to do that.

''Oh, by the way, wasn't the demon race monogamous ......?

　I had heard from Set before that it was monogamous.

''Master Cain, the demon race also differs from country to country. There are only two demon countries that are monogamous. By the way, Lisabeth-sama's imperial kingdom has a polygamy system.

　Cain nodded at the explanation from Dalmatia.

'Normally I would not want to return. ...... I have left the country without permission. So, no. ......

　Lizabeth's expression darkens a little.

''After that, I'll start. There was actually a demon race disguised in the arena where Cain-sama helped Lizabeth-sama. ...... It seems that that person immediately returned to the imperial kingdom and reported back. So, ---- the higher-ups within the imperial kingdom ......

Maybe you'll come looking for me here: ......?

　Lizabeth nodded apologetically to Cain, who was surprised.
　Even though she was an imperial princess, Cain wondered if she was that serious about looking for one person.

''Cain-sama, Lizabeth-sama's country is called the Benecitos Imperial State, which is completely different from other nations, even if they are demons. Other nations can call themselves 'Demon King' depending on their abilities. However, only the Benesitos Kingdom has the authority to recognize the name of the Demon King of each country, and the head of the Benesitos Kingdom has the authority to call himself the Demon Emperor. And only the imperial kingdom has such a long history that it is said to be thousands of years old.

　Cain sighs heavily at Dalmatia's explanation.

(That's how long the history ...... of the king, or rather, the same as the emperor's family in his previous life ....... That's why Dalmatia was up to her knees when they first met ......)

　But talking about it here and there won't make any progress.

''--That's right. Let's call Set!

　If you call Set, the head of a country, you might be able to get a little more information about the situation of the demon race, Cain said, casting a summoning spell.
　Set appears along with the magic circle.
　It has been a long time since Set summoned, but his expression was different from the usual.

　
''Cain-sama, it's been a while since I've seen you. However, this is a momentous occasion for all demonkind.

　Set, who appeared, was looking uncanny, as if a battle was about to take place.

It's a big deal for us too. So I thought I'd talk to Set about it. ......

　At Cain's words, Set nodded widely, thinking for a moment.

''Then I would like to discuss ...... with you. It's a big deal for the human race: ----

　Set looks at Lizabeth, who is sitting across from Cain, and - as it is - she freezes.
　Her eyes widened as if this was still a surprise.
　Then he looked at Cain with a mechanical movement that seemed to make a squeaking sound.

''Nah, why is Lisabeth-sama here ......?''

　Cain urged the upset Set to sit down next to him, but Set dropped to his knees on the spot and bowed his head.

'Good day to you, Lady Lizabeth. It's been a long time since I've seen you. ......

　At Set's attitude, Lizabeth smiled like an imperial princess.

"Set-sama, it's been a long time. It's been a long time since Set took over as the Demon King.
Yes, sir!　But still, why are you here: ......?　Now, the entire demon clan has come together to make sure that Master Lisabeth is a part of ......
Set-sama, take a seat first. I'll explain it to you. ......

　Set nods at Lizabeth's words and sits down next to Cain.

　Then Lizabeth explains what has happened since they left the empire, and with every word, Set is surprised, then angry, and finally relieved.
　When the explanation is finished, Set leans back exhaustedly.

'So ...... what's the big deal on Set's end ......?

　At Cain's words, Set opened his mouth as if he remembered.

''In fact, all of the demon race nations have decided to declare a ---- war on all ...... human race nations...'' ...

　The shocking words came out of Set's mouth.
