Jack's POV

I was currently in my room when Sento came in with a blonde girl.

"Master this my familiar Sylphy," Sento said.

"Hi," Sylphy said.

"Hello what can I do for you?"

"Mistress Sento Isuzu has told me about you and how you please her and all the other women in your harem so I was wondering would you let me join?"

"Sure the more the better," I said as I got up and kissed her.

I then heard the door close and saw that Sento had not only locked but that she was undressing.

"I hope you don't mind me joining," Sento said after taking off all her clothes.

"Like I said the more the better," I replied before kissing her.

I then pushed Sento and Sylphy on my bed and lined up my dick with Sento's pussy. I then started to tease her entrance while fingering Sylphy making her moan.

"Master please put in already," Sento shouted.

"As you wish but first tell me and Sylphy what a loyal servant and concubine you are," I replied.

"My body has been yours since I joined your peerage and harem. I can only get pleasure from you," Sento moaned.

"Good girl," I replied and I started thrusting into her pussy.

After a few minutes of thrusting I came inside Sento's pussy and pulled out. After pulling out I lined my dick with Sylphy's pussy.

"You ready?"

"Yes," Sylphy moaned.

A few seconds after she replied I quickly started thrusting into her pussy quickly taking her virginity.

"So good," Sylphy moaned.

A few minutes later I came inside her pussy. I then laid between Sento and Sylphy.

"So are you happy that you joined my harem?"

Sylphy then kissed me.

"Yes," Sylphy replied before kissing me again.

At that moment someone started knocking on my door.

I then got up to answer it and found it was Yasaka.

"I hope I didn't ruin your fun," Yasaka said.

"Nope I just finished what is it?"

"Vali contacted me he says that he, Ajuka and Grayfia want to meet with you right away," Yasaka said.

Break

I was in the same building in Lilith were I had first meet most of the new satans. With me was Yasaka, Saphira, and Tiamat. Yasaka came with me since she was my queen and felt it was her duty to be my side since I was her King which I agreed with. Saphira and Tiamat were in their human forms and came here to not only act as my bodyguards but to also confront Vali.

Before Saphira hatched from her egg Vali killed Saphira's parents when they refused to become his familiars. During the fight Saphira's egg landed in a river which washed her away from Tiamat. Because of this Saphira thought Tiamat's clan had abandoned her and thus resented her. In reality Tiamat had searched for her but after a while gave up the search. It was only when Tannin had told her the truth before he first trained us when I came back to the underworld that she started to no longer resented Tiamat or her clan.

We entered the same room as last time and naturally Vali, Grayfia, and Ajuka were waiting for us.

Before I could say anything Saphira approached Vali.

"You killed my parents if you weren't on good terms with my master or the new lucifer I would kill you," Saphira angrily told Vali.

"Saphira!" Me and Yasaka exclaimed.

"Saphira and I want compensation for what you did although not in blood as Saphira suggested," Tiamat said.

"I'm sorry but I'm afraid I don't know what you are referring to," Vali said.

"Why you…"

"Hang on Saphira his scent and aura is different from when he attacked and killed your parents. While I was a good distance away I could catch his scent and feel his aura it's completely different," Tiamat said while keeping her left arm in front of Saphira to stop her from doing anything rash.

"You know Grayfia's brother had a knockoff of my sacred gear. Considering what Tiamat said and the fact Vali didn't recall Saphira's parents could it be possible that someone has a knockoff of Vali's sacred gear?"

"I have to agree with Jack I believe that someone else did kill Saphira's parents. How that person created an artificial version of Vali's sacred gear, his motives , and his identity are unknown. But we will find this fake white dragon emperor," Ajuka said.

"I agree I'm personally offended that someone would tarnish my sacred gear by creating a knock off. I understand how you and Ddraig felt about Euclid Jack," Vali said.

"Finding this fake white dragon emperor won't be easy there isn't much evidence that gives us any clues as to where we can find him or his identity," Grayfia said.

"We can at least try. I hope that good enough for you Tiamat and Saphira as well," Vali said.

"It is," Tiamat and Saphira responded.

"Now that's settled why did you summon me?"

"About three years ago the three factions detected strange energy signals in Jasper, Nevada. There was some speculation as to what it could be but for various reasons it was never investigated. After you became a devil it was assumed you might have somehow been creating those energy signals but we have recently detected them again and since you're no longer living there it can't be you," Ajuka said.

"So how do I play apart in this?"

"We want you to investigate it and see if whatever is creating those energy signals is friend or foe," Ajuka said.

"Me!? With all due respect I would be away from my harem and that's something I'm just not okay with. Besides I'm not an investigator," I said.

"I thought you might say that which is why I decided to kill two birds with stones," Ajuka said causing me to get a bit confused.

Ajuka then used a large screen to display an image.

"Yo, Jack. Is it spring on your side now? The battle over here is in full swing," Azazel said from the screen.

I was surprised to see him.

"Azazel what's going on in there?"

I was so excited that I grabbed the screen as I shouted!

"It's nothing surprising, this is simply a form of communication between the isolation barrier," Azazel said as he threw a spear of light out towards somewhere.

"Something like this is actually possible!?"

I thought that as soon as they went in there that I would never be able to see nor speak to them again, so this information shocked me!

"Of course. We can contact each other regularly; if we couldn't communicate about the situation of the battle over here, I wouldn't be able to speak to you either, right? Also, if supplies aren't sent over to us, we won't be able to fight a protracted battle," Azazel said

Thinking carefully about it, it made sense Azazel went into the barrier because he had made these kinds of preparations. I just didn't expect that the isolation barrier was so well prepared for.

"The only things that cannot exit from the inside are Sirzechs and the others, as well as Trihexa. The exchange of information and transfer of goods are all possible. This matter is currently confidential, and only a few people are aware of it. Those few people are those in this room and the other leaders of the three factions," Ajuka explained.

"Using the information on Trihexa that we have obtained, it's possible that you guys might be able to develop relevant countermeasures, or approaches, right? If that's possible, perhaps this can be over in less than ten thousand years," Azazel said.

"Ah! What! Who are you talking with? Could it possibly be Sona!?"

I heard a very familiar, cheery voice! Serafall Leviathan appeared on the display! She doesn't appear to have changed very much.

"No, it's Jack. It looks like things over there have settled down a bit, so I'm assuming that's why we can get in touch with you."

Serafall seemed to cry after she heard that.

"Uuh, I really want to talk to Sona soon! I'm going to collapse because of my Sona deficiency!"

"Fufufu, Serafall. Sona can't find out about the way we communicate. Didn't we all decide that only Jack alone would know about this right now with the exception of future of the three factions?"

And then came a nostalgic voice that I had missed It was Sirzechs! Though, he was currently in his destruction form, rather than his usual red haired appearance.

"Sirzechs!?"

"Hey, Jack. Have you been well? You collapsed when we parted, so I was worried about you," Sirzechs said.

"I'm doing well! Perfectly healthy! I thought that I would never see you all again in my lifetime and that I wouldn't be able to speak to you again…!"

"Although we may not be able to see each other face to face, we can at least talk to each other occasionally like this," Azazel said.

"Former Governor Azazel, Sirzechs, let us speak about the earlier topic," Ajuka said changing the subject.

"Hmm, having to fight while talking is just a bit difficult, so I'll make it brief. Jack, before we headed in here, there was a discussion between the VIPs of the Three Factions. Accurately speaking, it was before you rushed off to Agreas to save your mom that this matter was already decided on," Azazel said.

"I will be establishing a secret intelligence bureau. Using an example from the human world, it would be similar to the American CIA, or the English MI6," Ajuka said.

"I hope that you can join it as an intelligence officer. From here on, there will be more and more people who act in order to take control of the world. It is necessary to protect the future, so it is necessary to remove evil while it is still being immature, which is why I hope that you'll be able to join," Sirzechs said.

"This is a request not only from Sirzechs, but also from me," Azazel said with a serious tone.

"In the future, there will be more and more cases that will need to be dealt with secretly. That's why an organisation like this is necessary," Ajuka said.

"We plan to name the organisation EXE," Sirzechs said.

"You originally belonged to the anti-terrorist team DxD, and you also possess the flesh of DxD Great Red, and at the same time you are also called DxD. The next one after 'D' — is 'E', which is in the title of the organisation ExE that you will belong to. Don't you think that this is a fateful choice? The organisation's establishment is planned for two to three years in the future. For now, we need to focus on post-war rehabilitation," Ajuka said.

"I hope that you will be able to stand at the centre of the organisation in the future," Sirzechs said.

"However despite the organization being established in a few years we have a mission for you. Did Ajuka tell you about the energy signals where you used to live with your mom?"

"Yes and I'm not sure if I want to take it. If I take I would probably not be able to take any of my peerage let alone my harem with me. I would miss them," I replied.

"True your harem can't come with you however you can visit them as long as you do it secretly so it doesn't ruin your investigation. You also have your celestial spirits you can always summon to keep you company," Sirzechs said.

"You have a point," I said.

"Hey Jack how many pieces do you have that are unused?"

"I have three pawn pieces Azazel why do you ask?"

"If the energy signal is being caused by a being you might be able to recruit said being into your peerage," Azazel said.

"While you're gone I can finish my training as the new head maid. Which means when you get back I'll be wearing a maid outfit," Yasaka teases.

"I can also use the time to train Saphira personally. I can make her stronger than she already is," Tiamat said

"Alright I'll do it," I said.

"Great you will need this," Ajuka then handed me a ring.

"What this?"

"This was Lancelot's ring it will prevent beings from being able to detect you. I have added some modifications so the ring itself will turn invisible to avoid any unwanted attention and to hide your muscles so people think you're weak," Ajuka explained.

"We have to go soon. Jack it was good seeing you. Grayfia I wish I could have talked with you I miss you," Sirzechs said.

"As do I," Grayfia said before the screen turned off.

A/N: So I recently watched the dub version of amagi brillant park and I realized that Isuzu Sento is actually Sento Isuzu. For those who might be confused what I'm saying is Sento is her first name not her last name. I currently do not plan on going back in previous chapters to fix this error however I will obviously not be making the same error again in future chapters.
