Hello there, Skylinemaster here with the last installment of Chronicles of the Satan Civil War.

"Speech."

Disclaimer: I don't own anything from Highschool DxD

"Daddy!"

My son, Shinji, shouted in the other room.

"Yes?"

I said as I rushed into the room, where Shinji and my daughter, Asuka, were in.

I looked worried but then I saw the book in my son's hand.

It's that book.

My journal from the war.

How long has it been?

Ten, no eleven years.

Yes, Shinji, I had Shinji immediately after the war ended, and he is eleven years old now.

"Did you really do all of these things in this book?"

Shinji asked me.

I picked up the book, and flipped through the pages.

It is quite sad that I only have six entries in this book.

Ah, the memories are coming back.

"Son, I did do all of this. But that was a long time ago."

I said as I gave the book back to my son.

"What is all this noise this early?"

My wife's voice said from the doorway.

I smiled and turned around to see my wife with a sleepy expression on her face.

Rias.

"Sorry Rias, Shinji was just looking through the box of my war materials and found my journal."

I said as she smiled at us while coming closer.

"What did I tell you about rummaging through your dad's stuff?"

She said at our kids.

"I'm sorry mommy."

They said in unison, especially Asuka with her pouting face.

"Don't apologize to me, apologize to your father."

She said as she gave me a good morning kiss.

"Sorry daddy."

"It is no problem. Now go play outside."

I said as they nodded.

"So, they found your journal?"

"Yes Rias. So many memories from the war."

"I remember. After the victory celebration, we started dating and we got married a few months afterward before having Shinji."

Indeed Rias.

I smiled as I glanced at the door, where my head maid was standing.

I ushered her in, and she whispered in my ear.

I nodded as she told me Ajuka was coming.

"Send him in."

I said as she went out of the room, and reappeared shortly afterward with my fellow Satan in tow.

"Ajuka, good morning."

I said as the maid left.

"Good morning, Issei. Good morning Rias."

"Good morning Ajuka."

Rias said as she looked at him with a questioning face.

"I am here to deliver the pieces to your son."

He said as Rias whispered in my ear, questioning me as to what the pieces he is talking about.

"You didn't tell her?"

Ajuka asked me.

"I thought it was still considered classified information?"

"This is the unveiling, so you could have told her ahead of time."

"What are you two talking about?"

Rias said with a pout.

"These."

Ajuka said as he held out a box of red Chess pieces.

"These are pieces that I've created that can replenish our numbers."

He said as I looked at Rias's surprised face.

"During the war, we've recovered information from the Old Satan Faction that can revive the dead, and Ajuka refined that information."

I explained to Rias.

"Yes. I believe that in order to replenish our numbers, we need to transform other races into Devils, and these pieces will be suitable for that purpose. As such, I believe that every young Devil heir should have access to such pieces."

Ajuka finished.

"And why didn't you tell me something like this earlier?"

Rias asked me as a dark aura encircled her body.

I looked at Ajuka for words, but he just turned away from me during my time of need.

Help a brother out!

"Yeah sorry Rias, can't hear you right now, I have to go to work as Satan!"

I said as I ran out of the room.

Phew.

I will not have Rias be that angry with me in the morning. It happened once before, and I'd rather not deal with that this early in.

Alright, managed to get to work safely and in one piece before Rias had a complete meltdown in front of me.

I am right now walking the halls of the Palace of the Satans in central Lilith. The Palace of the Satans is an entire campus of buildings where each Satan does their work, and the central building, which acts as a meeting hall for all of us.

This is the former head of government of the old regime, and it is now functioning as the place of our current regime.

My building is in the Northeast section of the Palace.

The Palace of Mammon.

My duty is to oversee the financial aspects of the Underworld, and as Mammon, it is my duty to regulate commerce, business, and to ensure fair trade and competition throughout the Devil Underworld and parts of the Human world.

Under my watch, the First National Bank of the Underworld was created, as was the HSE, the Hell Stock Exchange.

I see my assistant in front of the building, waiting for me with the briefcase of today's agenda.

"Good morning, Kiba."

"Good morning, Director."

Kiba said as I shook my head.

"How many times have I told you, it is Issei. I swear that you did this during the war too."

That's right. Kiba Yuuto is my second in command here, just like he was back in the days of the war. After the war, I became Mammon and needed good people to surround myself with. There were many exceptional people who wanted to become my right hand man, and Kiba was the most exceptional out of all of them. So I took him in as my assistant, and he has been absolutely essential to my duty as Satan Mammon.

"What is on the agenda?"

I asked him as he gave me my daily morning drink, something the Humans refer to as tea.

"A meeting with the Treasury over the proposed minting of new currency, a lunch with the head of the Belial family, and a dinner with Satan Lucifer and his wife later tonight."

I nodded as the events were known.

Ah, Kiba, I wouldn't know what to do without you.

Alright, let's get this day over with.

Whew, I'm exhausted.

The meeting was boring and tedious, just like the other meetings with the Treasury.

Diehauser Belial's house, I must say, has some of the best chefs throughout the Underworld, and that is saying something. We had a beautiful lunch at his lakeside chateau near Lake Goap. We discussed various topics, and the lunch was very good, if not great.

Now, now begins the dinner I am having with Satan Lucifer and Grayfia, or if I am not being formal, my brother in law and his wife.

I am approaching the gates of Sirzechs' mansion in Lucifaad, where he told me he had something very important to discuss with me.

So important that it must be in person at the comfort of his house, and that it couldn't be done at the Satans Palace.

"Rudolph."

I smiled at Sirzechs loyal butler.

He is always so kind to me, even when I was a little boy.

"Master Sirzechs is waiting."

Then let's not keep him waiting any longer, shall we?

I followed behind Rudolph to Sirzechs' working room before Rudolph turned around and waited in front of the room.

"After you, sir."

He said as he opened the door for me.

"Surprise!"

Ah, they shouldn't have.

A surprise birthday party for me?

Very everyone is here.

Sirzechs, Grayfia, Ajuka, Serafall, Falbium, Kiba, and of course, Rias, who is holding the giant birthday cake for me in the center of the room.

Thanks Rias, I love you so much.

Well, I hope you enjoyed reading Chronicles of the Satan Civil War as much as I enjoyed writing it. Please leave a review to tell me your thoughts on it, and if you have an idea for a story that you want me to write, leave a review or shoot me a pm.

Thank you all for staying with this fanfic.

Until next time, Skylinemaster out.
