The crimson princess

The other devils, except Diablo, were members of my peerage.

Milim, the half-dragon, wanted to join Sera’s peerage, but due to her having more value than Sera’s Queen Mutation Piece, Rimuru will handle the modifications to the pieces for them.

After conquering the capital, we headed to other major cities to complete our mission.

Oni-sama apparently routed the Lucifuge Family, leaving only Grayfia and her brother Euclid as the remaining members.

Oni-sama also confronted Grayfia, who had lost herself in ambition after her encounter with Rimuru. Oni-sama showed her another path she could follow, and since then, Grayfia and Oni-sama have been a couple. (A little cheesy, but we follow Dia, not Sirzechs.)

As for Ajuka and Falbium, they easily defeated their opponents and killed the Satans.

This war was beginning to come to an end.

A few weeks later, we were all together with Zekram to judge the last remaining members of the Satan Houses.

Zekram said, "By the power we hold, we have decided to banish you and promise that you will be killed if you come back into our territory."

I was against the idea, as was Zekram, but Oni-sama chose to show mercy. So I made a bet with him: if the heirs came to us within the next 500 years, he would owe me a favor.

The heirs looked at us with hatred but left, knowing they would be killed if they made any wrong move.

Zekram said, "Now that this chapter is over, we must choose new leaders for our society."

Dia: "I’m warning you, I don’t want to take their place."

Sera: "I’m fine with it, on the condition that Dia helps me when I’m overloaded."

Dia: "Of course, I would help you if you ever need it."

Zekram: "Stepping out of your world, you makes me feel like vomiting."

Sirzechs: "I accept, but only if I take the name of Lucifer."

His choice was logical, given that the Lucifuges must serve the Lucifers, so taking that name would allow Grayfia to stay by his side.

Grayfia, having changed completely, is now also part of the cult of maid supremacy.

In the end, it was decided that Ajuka would take the name Beelzebub, Falbium that of Asmodeus, and Sera that of Leviathan.

Knowing that I would now become the heir of the Gremory family, I decided to give up my first name and take my second name, Eucus.

My father and Zekram disagreed, but they couldn’t say anything because I promised to become the leader of the Gremory territory in the event I had no other sister or brother I had requested a territory to establish my faction. They didn’t agree because, to them, I had betrayed my race, but they couldn’t do anything since I was stronger than them, and many people supported me.

My territory will be in an area between the Devils and the Fallen Angels. It will require a lot of work, and I will need to inform everyone about the existence of a fourth faction within the biblical pantheon. But I’ll be fine—I have confidence in myself and a few witches.

A few months later, while I was finishing the construction to make the area where we would settle comfortable, I was suddenly summoned. When I opened my eyes, I was surprised to find myself in the territory of mermaids and tritons.

"Please, Dia-sama, I beg you. Save my daughter."

Before me was the king, with whom I had a good relationship, now completely submissive, pleading for my help.

 and if my father was unable to continue the policy.
