The Golden King of the Monsters (Male Reader × HSDxD × AGK × FT)

chapter special: Y/n's past

A/n: this chapter will be a loooong flashback. It's not really necessary but I wanted to do that. Sooo enjoy. And also, play this song during the whole chapter

18 years before the main story

Position: Tartaros Guild, Earthland.

Mard Geer was sitting on his throne, holding END's book and with his usual smirk. He was busy in making the plan to revive him. Until, Seilah entered.

Mard Geer: Seilah

Seilah: have you called me, Lord Mard Geer?

Mard Geer: I have a mission for you-

But before he could talk, the earth  trembled

Mard Geer: what's happening

Seilah: I don't know

And then a black hole opened, absorbing Seilah and Mard Geer.

Sirzechs POV:

I was at my home in Gremory land discussing with my comrades Serafall Leviathan and Ajuka Beelzebub about the evil pieces. Akuja said they would help us to rebuild our race, then I felt a huge amount of power and I saw two figures falling from the sky

Serafall: what happened Sirzechs-chan?

Sirzechs: there is someone with a huge power here, I want to check

I left home and I went where the power was. I saw a man with long black hairs in a large ponytail who was holding a book with the word END. With him there was a woman with golden horns

Mard Geer: I can sense you are not a mere human. Who are you?

Sirzechs: my name is Sirzechs Lucifer. I'm one of the four great satans. Who are you?

Mard Geer: I'm Mard Geer Tartaros. Underworld King and Absolute demon. While for her, her name is Seilah

Sirzechs: I see, how did you arrived here?

Mard Geer: we don't know that

Sirzechs: then why don't you stay at my home for a while

Seilah: we don't accept. We must find a way to go home

Sirzechs: then let's make a deal, Mard Geer. I'll challenge you and if you win, I'll give you a home

Mard Geer: it would be in the human world. But I suppose it will be alright

*timeskip after the battle*

Mard Geer POV:

The battle just finished and the winner was me. This Sirzechs had to give all his power while I was still in my human form pathetic. Anyway he promised us a house in the human world. I hate the fact of have to live among humans, but I can't kill them. The house was basically a huge mansion with the things I required. Me and Seilah entered, I think we will be here for quite a while

Seilah: not bad right Lord Mard Geer?

Mard Geer: yeah, we'll be here for a while

*timeskip night*

Third person POV

Now it was night. Etherious doesn't sleep normally, but the bed in the house took Mard Geer's attention and same for Seilah
