The Knight of Ruin(DxD)

Following the end of the wedding, Romonus and his wives went on their Honey Moon which went on to be inside the Demon God Realm which was the Underworld that Romonus had been feeding the essences of each Alternative Underworld he conquered. 

As a result, it was the biggest separate realm connected to Earth, and the Monsters and Plants that called it home had become truly monstrous things to be able to survive the sheer pleasure of Romonus' Infernal Divinity. 

Speaking of Romonus, while he and his wives enjoyed themselves at his Brass Citadel which also doubled as his Demon King Castle, he chose to bind the Demon God Realm even closer to his soul. 

In doing so, he effectively formed his own 'Heaven' but he felt it made more sense to call it Hell. In binding it to his soul, it was no longer bound to Earth and could only be accessed by those he allowed. 

It became not just a separate realm, but also a Soul Realm that would grow along with him. That did have the desired side effect of making his soul far stronger as he now has his realm that would protect his soul. 

His wives ended up loving that as the feeling of being enveloped in his Soul Realm was pleasant to them. They did begin to make his Demon King Castle more like a home as when he made it, he just made it for the fun of it. To do so, they teleported their house from Britain which they then fused with his Castle. 

This meant all of the rooms and other living arrangements were fused into the Castle giving the inside of the Demonic Castle a welcoming air for their family. Once their living situation was taken care of, they truly let loose as they enjoyed their Married Life. 

That did involve a lot of sex in different parts of the castle and as Rias promised, she dressed up as his secretary and roleplayed by giving him a blowjob and tit fuck while he sat at his desk managing the Underworld. 

He had to admit that made his work easier, but it got even better when Venelana joined in. That wasn't the only case of extreme sex, but sex was not all he did. He used his Completed Demonic Saint Cards on some of his wives. 

For his Evil Pieces, he currently had Shirone and Miria as his Rooks, Valerie, and Akeno as his Bishops, Tobio and Silvana as his Knights, and Itsuki, Kouki, and Natsume as his Pawns. 

It meant he still had his Queen Piece open along with his Mutation Pawn and a regular Pawn remaining. His Mutation Queen and Pawn both had been severely mutated by his Infernal Divinity meaning whoever received those would become stronger than ever.

Even the Regular Pawn he had used was mighty, but he left his Evil Pieces alone. Instead, he began to use his cards to enhance his Lover's abillities through the Demonic Saints. 

He had a Queen, Jack, Ten, Nine, Eight, Seven, Six, Five, Four, Three, Two, Ace and a Joker card. Meaning, he had three Mutation Pieces as he had two Mutation Evil Pieces and a Brave Saint Joker Card. 

His lovers did not refuse so he began to use his cards. He turned Venelana into his Queen, Vespera into his Jack, Serafall into his Ten Card, Roygun into his 9 cards, Latia as his 8, Rias as his seven, Seekvaira, his 6, Kuroka his 5, and Walburga his four. 

As for Viviana, he chose to use his Ace card on her so he still has his Joker, 3, and 2 free for later. When he did that, all of his lovers effectively stopped being Devils and became Demons. 

All of their abillities were enhanced just like those he had used his Evil Pieces on. Now, all his harem was on equal footing, however, Ophis was not included in that. Since she was a Dragon God he didn't think there was any need to change that. 

Just as he was going to do something else, Ophis grabbed his Joker card and infused it with her essence before binding it to her soul. That effectively made her his Joker card which made it into a Demonic Dragon God with her Dragon side being dominant. 

He was quite surprised to see that, but he welcomed it. With his Demonic Pieces, Demonic Saints taken care of he went back to enjoying his married life. He stayed out of politics and kept to himself for over a year doing nothing more than truly relaxing with his wives. 

He gave his attention to every one of them as they deserved to be treated like Queens. For that entire year, he and each of his wives made the most of their time being married. 

At the end of the year, they returned to the Underworld. When they returned, Romonus the Demon God, and his Wives the Demon Queens took control of the 72 Pillars and the entire Underworld. 

While Romonus controlled the Underworld, he honestly couldn't care less about ruling the Pillars. He took a hands-off approach until someone stepped on his toes which required his Demons or Shadows to deal with it. 

Not many had the balls to do so and those that did were just too stupid to do so. With the alliances of his allies and his overwhelming power, Romonus stabilized the Underworld which without his orders chose to unite rather as Clans, as an Empire. 

The Fallen Angels, Werewolves, Vampires, Cultivators, and Dullahans, joined in which made Romonus' next action feel right. Just as he had said, he changed the Four Satan System to the Seven Great Demon Princes. 

He allowed Falbium to retire as he had promised leaving the position as Asmodeus empty. As such, he began to put people he trusted as the Seven Princes. He didn't let his brother retire so he stayed as Lucifer, but he gave him more vacation days. 

He placed Sairaorg as the new Mammon making Sairaorg the first Satan Mammon. To replace Falbium, he allowed Azazel the honor that he was not expecting. However, he accepted that with seven Satans they wouldn't have as much trouble. 

To replace Falbium, he put Arjac in place which the Werewolf King accepted with Honor making Arjac the new Asmodeus. Serafall chose to step down, but she kept her Leviathan last name as Romonus liked it. 

However, the position of Leviathan was taken by her Father Lord Sitri. Ajuka remained as Beelzebub and Romonus took the position of Satan and Demon King. The new Seven Great Demon Princes took over controlling the Underworld in his stead.

To make ruling less of a chore, each Demon Prince had their teams work through paperwork or bureaucracy. The old Council was disbanded and replaced by a council made up of all the allied races of the alliance. 

The Old Devil Council was angry, but when they tried to complain they were merely executed. With the new system of ruling in charge, all the efforts of the Underworld Alliance were on rebuilding their strength. 

To do so, Azazel and Valerie created new fertility potions for cheap that made it a guarantee for Devils, Fallen, and any other race to get pregnant the first time. That caused birth rates to skyrocket including far more hybrids than before. 

Sona, through the support of her sister, built her school to accommodate all of the new children being born through the Underworld. Social Class didn't matter and neither did race with the rise of hybrids. 

Such Schools were set up in every city with Lucifade which was a giant city built in Honor of Romonus housing the largest one named Demon King Academy. It was on the nose, but Romonus didn't care. 

For the next 25 years, Romonus, his wives, and his friends led the Underworld to progress. They even helped the surviving remnants of the extinct clans to repopulate by the order of Sairaorg Mammon. 

25 years was a long time and a lot had changed for everyone, especially Romonus and his family.

Asterion Gremory the younger half-brother of Romonus walked toward a towering castle gate. Standing at the front were two Greater Shadow Demons the fusion of Shadows and Demons. These days, Romonus has fused both armies to create the perfect fusion of Demon and Shadow. 

Asterion's black hair was long and flowing while a neat beard covered his face. He was tall much like his brother at 6'6. Unlike Sirzechs, he didn't mind drinking a potion made by his older brother Romonus to get taller. 

It got him great success with his harem, but he didn't follow the example of his Father. That was a quick road to failure as Zeoticus showed. As he approached the gate to Romonus' Demon Castle, the Shadow Demons pushed the gate open for him. Asterion made his way inside the castle before taking the teleport gate manned by several Necrons.

When he opened his eyes he found himself not in a giant Throne Roon, but a regular living room. Here, he saw Romonus sitting on a giant couch as they watched TV. Asterion smiled as he saw his brother, Romonus now 65 years old. 

The use of Time Formations, and how often they raided the Multiverse made it so they aged more than was expected. Despite their age, with their infinite life spans it was as if only a few days had passed. 

There were also some new people here that Asterion had not met since his brother and his wives had become reclusive in Romonus' Soul Realm. One was a blue-haired, blue-eyed, horned woman who was Tiamat, Romonus Queen. The other was a small black and silver spiked wolf which was Fenrir, Romonus Mutation Pawn. The other was someone Asterion recognized as being Ingvild Leviathan. 

She had been brought here by Leviathan herself after healing her from her sleeping diseases. Asterion placed a hand over his chest before he gave a short bow. Out of respect for his brother. 

"Brother, sisters-in-law, it has been far too long. How are you all?" 

Romonus didn't stand up as he turned to see his younger brother. Everyone else in the room did the same as it wasn't just his wives here. Romonus brought up a fat cigar up to his lips which he cut with a wave of his finger. 

He them lit it up with a puff of fire before he took a drag before he exhaled the smoke. 

"We have been well. We were enjoying our 'quote on quote' retirement. We have grown rather bored of raiding other Earths and Universes." 

Sitting at the mini bar, Ophos raised a glass of powerful alcohol. 

"True that, we planned to end the Evie, but after killing them in another Multiverse 500 times, they stopped being a bother. We even discovered the Dark Multiverse and that was fun." 

Lady Red sitting next to him took a light drink from her glass with a nod. 

"True, it did lose its charm and then we chose to have our mini vacation. Which turned into 40 years."

Ophis who was with Romonus turned to her Father and Aunt with a smile. 

"It wasn't just a vacation, we were training." 

Someone else sitting with Romonus spoke this time. 

"Exactly, we barely had time to relax." 

Lady Red turned her head to look at her and Ophos' sister Trihexa who was currently sitting next to Romonus. She wasn't married to him, but she was one of his new girlfriends. After Lady Red had trained Trihexa to be a sentient creature, she sent her to live with Romonus. 

Trihexa had a spiky crown of horns, pale white skin, and seven pupils in her eyes. When Asterion heard that he sighed as he looked at his brother. 

"Brother, you have grown lazy in your old age haven't you." 

Romonus shook his head as if he had been working hard just on something different. He continued to drag on his cigar before turning to Latia. 

"Latia, tell this stupid boy what we have been working on." 

Latia who still looked as perfect as she always did smiled. 

"I and all of our magic experts have been working on a way to turn the Dimensional Gap's energy into a way to leave our reality. Not our Multiverse as we have already destroyed over 500 of those. Another 100 Dark Multiverses as well. 

We did all the research we could on the Multiverse and learned all we needed. This is a little-known secret, but Romonus, as he is now, is so strong that in one of the Dark Multiverses, he blew up a small Galaxy Cluster when he went all out." 

Asterion rubbed his head as that was far too much. 

"Now that is insane, are all of you that strong." 

He saw a bunch of smiles as none of them had been slacking. Each one had fed on hundreds of gods, and their alternative selves. Among Romonus' family, the strongest would be Ophis who through her Demonic Dragon God status with her concepts and abillities. 

The ranking of them all was contested and ever-changing, but no one had come close to beating her. Though, with Asterion here, Romonus made his choice. He stood up and shook his head. 

"Alright them, let us deal with the Evie now and put all our efforts into leaving this reality."

All of his wives and lovers got up along with Ophos and Lady Red. Even his Familiars in Azi, Kharn, Grimaldus, Mephiston, and Fenrir had been added to that list. It was time to end the Evie who were not even a threat. 

With them dead, they would put all their efforts into traveling out of Dragon Deus as it had grown borring. It was time for the outside realities to tremble at the name Romonus.
