"What does she ever see in that loser?"

That was the only thing Andrew thought as he read the Light Novel of High School DxD. Rias Gremory the main heroine must have a screw loose if she fell in love with Issei of all people. Even after he read the entire series, he still felt that Issei was a weirdo, but a lucky weirdo.

He tossed the novel onto his bed as he sat down in his gaming chair.

"It is an anime world, so logic is bound to be lost, but still."

He squinted his eyes as he pondered on the universe of DxD. As long as you were not a mob, it was a wonderful place where it was all but guaranteed you would score with baddies. If you were a mob, good luck getting any women to like you as Issei was lucky to have Dragon Rizz active.

He got up from his chair and looked at himself in the mirror. He smiled proudly as he looked at his trained body.

"Bet if I was in his case I'd score even more. Just look at me."

He flexed his muscles and while at 17, he was 6'3. He wasn't in sports or anything as he hated them, but he worked out just for this reason.

"If I had powers, I'd bench a planet."

'Is that a fact?'

"HUH!"

He knew damn well no one else was In the house so hearing another voice freaked him out. Before he could even clench his fists to fight back he was no longer in his room.

Instead, he was sitting in front of a middle-aged man in a business suit. The man was reading a file on it before he looked up at him. Creepy enough the man had yellow glowing eyes and a massive scar down the right side of his face. 

"Welcome young man. I am Rhavdall. The god of Insanity. One of many."

Andrew didn't know how to take that.

"You aren't going to drive me insane are you?"

Rhavdall squinted his eyes and stared at Andrew.

"No. We lesser gods are many and together we make these companies essentially where we reincarnate random people like you. Some get lucky when they say some keywords like you did."

Andrew rubbed the back of his head as that sounded dumb.

"Really? That's it?"

Rhavdall nodded.

"That is it. Now then, looking over your file you are quite an extraordinary young man. 6'3 is above average, your muscle definition is extraordinary and your intelligence is above average. You will do nicely. Now then, DxD?"

"Sure. Do I get to pick the powers?"

"Of course. You get 1."

"What's the catch?"

Rhavdall smirked.

"Smart indeed. In exchange, when you get to your new world make a mess of things. Change the destiny of that world as much as you can. The more changes you make the better. That chaos caused by the breaking of fate is what a god like me feeds on. Fair?"

Andrew smiled.

"Oh for sure. 1 wish? I got a request, not a wish, but I am sure you would get more chaos out of it."

Rhavdall truly grinned.

"What is it?"

"Make me the twin of Rias Gremory. Just by being her twin, I am almost guaranteed to get her bloodline abilities. With that and me being in the Gremory clan Fate will begin to change. Causing that Chaos you feed on. Things sure are going to grow wild."

Rhavdall's face turned almost cheshire in nature as he liked the sound of that. 

"Agreed. If anyone asks, this is my idea. Now then, what is your wish? You only get one."

"I want the Gravity Magic Demon Lord Wilbert had from the better version of DxD. Testament of a Sister New Devil." 

Rhavdall's face began to distort showing why he was a god of Insanity.

"Andrew, do your worst. I am expecting great things from you, my boy."

"As am I."

That was all he knew as he blacked out. By the time he opened his eyes, he was already being born. And it was terrible as coming out while conscious felt like being crushed.

He felt bad for Venalana, but she was a Devil so she had magic to make things easier. That was a fact as she had pain numbing spells and healing to make this easier.

When he was out, he was cleaned off with a wave of magic from the midwife who was of course a pretty Devil lady. It was hard to find an ugly female Devil as they all could change their appearance easily.

"The first of the twins is a boy, my lady."

Venelana looked up with a pained expression, but less than should be felt.

"Dear, hold him for now while I pass the second."

Zeoticus nodded as he let go of her hand and took him into his hands. Meanwhile, Venelana focused on birthing her second baby which was Rias.

 Andrew meanwhile looked up at Zeoticus who looked just like in the anime. Only clean-shaven as it seemed he grew the beard out later.

"The heir to the Gremory clan has been born. Romonus Gremory is your name."

'Romonus, that sounds awesome. I am taking it.'

Venelana pushed more as she birthed Rias, who was easier than Romonus. Once Rias was out, the same attendant used magic to cut the cord and clean off the blood. 

It was that easy as the birth, all things considered, had been effortless.

Zeoticus passed Romonus back to his wife, who pressed him and Rias against her breasts.

'Breastfeeding all over again.'

Both began to drink, which made Venelana smile.

"Twins are a rare gift. Rias has been born." 

They had both been allowed to name one, and Zeoticus had chosen to name his second son, of course. However, when he got a look at Romonus, he could see he had bright purple eyes like a Bael, and his hair was pitch black, just like Lord Bael's Father.

He was also Venelana's Father and he had engaged to her him. It was mildly annoying that his son looked more like the Bael clan, but Rias did have the crimson hair of the Gremory.

That was to be expected when the Bael were the first Devil Clan created meaning their genetics were purer. He was just happy to have twins as Devils seldom had twins.

Birth rates were so low that they had not expected Venelana to fall pregnant.

"I am over the moon and Sirzechs will be just as pleased. He now has two siblings."

Venelana now brought up a good point.

"So Romonus is the heir?"

Zeoticus nodded. 

"He is the second born and male. If Rias proves to be more talented or better at politics she can be the heir, but until then Romonus shall be our heir."

"I see."

Venelana was not pleased as their society usual male dominated. With a sigh, she just enjoyed this simple time when they did not have to think of politics. How long would that last? Not long enough.

—

After being born, Romonus of course was defenseless as any infant was. He and Rias were often breastfed by their mother, but when she couldn't attend to them they would be breastfed by Wet Nurses.

He was over the moon as all Female Devils were hotties with great bodies and breasts. By being a Noble, he was fed and looked after by many. And he learned an interesting thing about Devils, they had literal spells to induce lactation.

That was hot as hell and he was sure to use that in the future if and when he got his harem. Just imagining getting breastfed by Yasaka or a Fallen Angel named Kalawarna got him going. 

Though, for now, he just enjoyed being a spoiled little brat seeing and sucking more boobs than most men saw. And as weird as it was, the more he was breastfed the more energetic he felt. 

Then again, Devils were a magical race so for all he knew their breast milk made their babies stronger. But the best out of everyone was still Venelana who was a very powerful Devil Lady. 

And her boobs were huge, but while she may be his mother, he could still appreciate her breasts. Even as a Devil, the first year of his life was a time of barely any activity as even when he started walking at 7 months, he was still mostly useless. 

But by the time he became a year old, he began to get a feel for his Demonic Energy or Power. He preferred to call it Energy, but by simply being born a Gremory he was born was much Greater Demonic Energy than other Devils on top of the Bael Power of Destruction. 

Those two abilities alone could allow him to become a second Sirzechs or greater, but he also had Gravity Magic to master. By being born a Devil he was already ageless up to a certain point, but he was not going to waste his formative years when one learned best. 

That was why he wanted to get a hold of his own 'Magic' early. Unlike him, Rias was still a regular baby so she was just sleeping in her crib. As for him, he had gotten out of his crib and walked his unbalanced baby body to the couch. 

'Come on stupid head, work.' 

Once he got to the couch, he dragged himself up and sat down. It had been a year since he was sent into this world and things had been normal. He had been like any newborn getting his diapers changed, getting breastfed, and being played with by his new family. 

It was nice, but now that he could hold coherent thought for longer than a few moments without headaches, he could begin training. He had two active abilities to Master, and one Passive to boost them. 

'Power of Destruction, and Gravity. OP if done right, Rias if done wrong.' 

He snorted as he looked in the direction of the sleeping heroine of the anime. She turned over and kept sleeping which made him think of something. What could he do to make sure she didn't stay weak to not rely on Issei? If she was his twin, her reputation could ruin his own and she was cute later on. 

Rias was a political card as she was female and Zeoticus would want to hitch her to Riser. Instead of allowing Issei to take her as his boob power-ups Fate would change if he got in the middle. He grinned as he would cause the 'Fate' or canon of this world to change. For the better or worse who could tell? 

For now, he closed crossed his legs, and sat down like a Cultivator. He placed his hands on his knees and he focused. He got rid of any distracting thoughts and he just focused on himself. 

He imagined his Demonic Energy flowing through his body and manifesting it outside. Demonic Energy was reliant on an open mind and imagination which was easy for him. He was always imaginative and it seemed to be working. 

Slowly, a red aura began to manifest around his body as he got a feel for his Demonic Energy. Once it was manifested he got an idea and imagined it flowing through his body. 

The Demonic Energy outside his body began to shrink as instead of being pushed outside, it began to flow inside. When he did this he felt his entire body begin to burn like a hard workout as his stagnant Energy began to move. 

He did not know how long to keep this up, but like any work pushing too hard would be detrimental. When he felt that 'burn' become too bad he released it and gasped. He was covered in sweat and he was exhausted, but it was the good exhausted after his heavy workouts. 

'I will be so hungry after this, but rest.' 

He got down from the couch and walked toward his crib. As he did so, he could feel that he was using his body better than before. He was in the right direction as by 4 years old he wanted to get a hang of it which seemed a good time frame.
