Chapter One: Calem Meets Rob

I never pictured myself dying from being stabbed multiple times by some random nutjob, you know?

I always thought that I was somehow going to live up to old age and die from some random sickness or simply because my body just stopped working. Never would have I imagined that my death was going to happen like this: within a pool of my own blood in the middle of the grocery store I frequented as I stared at the frantic face of the kind old lady that ran it.

I just had to step in, right? It wasn't like I had a hero complex or was a particularly good person (far from it), but Old Margaret didn't deserve being robed like that by some scum and this was my grocery store. In the end, like always, I just acted out of selfishness even if my actions didn't appear as such.

Which, again, led to my untimely death.

And that bring us to my current predicament…

"… I was never a religious person but I'm pretty sure Hell isn't supposed to be like this," I spoke aloud as a stared at the whiteness around me. After losing consciousness due to blood loss, I found myself suddenly waking up naked and floating in this completely white space. There was literally nothing else around me. Only a seemingly endless white expanse.

I tried to make sense of what was happening but it only ended up making my head hurt. After what felt like an eternity, I gave up and closed my eyes. Was this my divine punishment? I mean, I know I am a selfish asshole with more than a few of kinky fetishes with an ego the size of Eurasia, but that's hardly grounds for such a harsh punishment. Other than masturbating at least twice a day and fantasizing about them, I never acted out on my deepest and darkest desires. So why was I here?

"Greetings, Calem Smith."

I gave a manly yelp at the sudden voice speaking right behind me and somehow managed to turn around and…

I blinked repeatedly, rubbed my eyes and blinked some more. "What in the actual fuck…"

The being in front of me, a vaguely androgynous and featureless figure colored completely black, tilted its head to the side. "I apologize if you find my true form disturbing, Calem Smith but that's not what matters the most right now," it said before pausing for a moment and then continuing. Its androgynous voice matched its appearance. "My name is Rob and I have a proposition for you."

Rob? What kind of fucking name was Rob for what was clearly a cosmic entity? Wait. Wait a fucking minute! Rob… R… O… B… Random Omnipotent Being…

My eyes widened in realization as I stared at it. "Don't tell me that you…"

Rob nodded its head. "Indeed. For the sake of my entertainment and that of other cosmic beings, I would like to send you to a Reality of your choosing, with powers and/or equipment of your own choosing, as well as when in the timeline you would like to start at. Our only request is that you change 'canon' as much as you can. We won't care what you do as long as it's different. So, what do you-!"

"I accept! Sign me the fuck in!" Reincarnation with those kinds of perks and free to do whatever I wanted? I didn't even have to think about it. That was literally my deepest and most desired dream come true.

Rob nodded. "Splendid. Now… what reality would you like to reincarnate in?"

This one was another that I didn't have to think about. I've been imagining myself living in this world ever since I started reading the Light Novels. "An AU version of Highschool DxD in which-!"

Rob interrupted me. "No need to tell me. During the incarnation process, your subconscious mind will make all the changes you want to that Reality," it said before pausing for a moment and then speaking again. "Now, chose your race, powers and equipment."

Now this time I actually took some time to decided. I wanted to be OP from the beginning, but not so OP that I could one-shot the strongest beings with a glance. That would make things boring really quick. However, I didn't want to be so weak that the strongest being could one-shot me with a glance. While it took me some time, I took less than what most people would have to come to a decision. I have fantasized about this before, so technically, I had prepared myself for this very moment.

"For my race, I want to be a type of nephilim," I started and continued after Rob tilted its head. "A hybrid between a devil and an angel. But not just any one… make me the 'offspring' of Lucifer Morningstar, the First Fallen Archangel that became The Devil, and a female Azrael, The Angel of Death. I just want a pair of wings… avian and colored a dull silver that darkens into black at the ends.

For powers I would like the ability to use the standard powers of Devils and Angels from Highschool DxD, meaning Demonic Power and Holy Power. For my Devil said, I'd like watered down versions of some of the powers of Lucifer Morningstar from DC, specifically the Demonic Energy Manipulation, Soul Manipulation, Necromancy, Psychokinesis, Pyrokinesis and Magic ability. For my Angel side, I'd like Holy Energy Manipulation, Time Manipulation, Space Manipulation and since I'll be 'offspring' of Azrael, further increased affinity with Soul Manipulation and Necromancy.

And as for equipment… I'd like the Sacred Gear Incinerate Anthem to compliment the Pyrokinesis abilities and Yamato and Rebellion, from Devil May Cry, to compliment and establish synergy and focus between my Demonic and Holy Light energies and to compliment my Space Manipulation abilities. Oh! And my own set of Evil Pieces, tied to me, King Piece included for myself and all of them mutated. I want my own Peerage."

Like I said, I've been kind of preparing for this moment… technically.

Rob seemed to consider for a long moment before nodding its head slowly. "That's acceptable and most certainly doable. Now, at which point in the timeline would you like to start at?"

I had already considered this when I was thinking about my race, powers and equipment. "There are somethings that I would like to change so put me around the time Rias is born. I also want some time to get a grasp of my abilities as well. If it's not too much to ask, can I get the knowledge on how to use all my powers. Not outright mastery, since that would be boring, but rather how to achieve it through training and continues use. If you can put me in the Underworld all the better."

Rob tilted its head. "Again, acceptable and doable. Would you like to change your appearance?"

I paused, considered and thought for a moment and then nodded my head resolutely. "Yeah. Make me the most beautiful, handsome and sexy male there, with a perfect musculature and a height of at least six feet. Use Kurokiba Ryo from Shokugeki no Soma as a base for my overall appearance. I already told you how I would like my wings so… black hair, eyes that seem to be on fire and fair skin. Oh! And last but not least: the perfect cock to satisfy all the females I'll make mine."

I didn't need a mirror to know that my grin was perhaps the most perverse thing anyone had seen on their live. Sure, I was a selfish bastard, but that didn't mean that I had to be the only one to enjoy the 'consequences' of my future actions. I could be thoughtful when I wanted.

Rob nodded. "Understood. Now off you go," it said before raising its upper right appendage and then snapping what passed off as its fingers.

My eyes rolled to the back of my head and I felt what could only be described as being stabbed multiple times all over my entire body, then being burned with the hottest of flames and finally being submerged in acid before I lost consciousness.

-XXX-

If it weren't so utterly boring and repetitive, I would have regaled you with the first seven years of being incarnated into the world of Highschool DxD… but there was no point in it, really. There had been a reason why I told Rob to put me around the time Rias was born. I wanted the chance to master my abilities and make my plans and schemes for the future to turn canon in on its head.

Thus, I made plans, scheme, counter-plans and counter schemes. All of them with the sole purpose of becoming the undisputable ruler of this world, the strongest and most powerful being in existence and getting all the females that were, or could be, sexually compatible with myself.

Would you do any different in my situation? I very much doubt so.

Apart from that, I used the knowledge I was given at my request to train up all my powers and abilities as much as I could until my self-imposed deadline arrived.

In seven years, I achieved complete mastery over my Demonic Energy Manipulation, Light Energy Manipulation, Pyrokinesis, Psychokinesis and Necromancy. When it came to my Soul Manipulation, Time Manipulation and Space Manipulation, I was very proficient with them but still had some time before becoming a master.

When it came to my equipment, since I used my Pyrokinesis alongside Incinerate Anthem, I mastered its use and even achieved my own subspecies Balance Breaker with it after bonding it completely with myself. I still wasn't aware of what it would take for me to achieve its equivalent to Juggernaut Drive/Breakdown the Beast, but I was very eager to find out.

In regards to using Yamato and Rebellion, I mastered the Dark Slayer Style and the Swordmaster Style used by Vergil and Dante respectively. Using the Yamato complimented my Space Manipulation abilities and the two blades helped immensely when I used raw Demonic Energy and Holy Energy.

About my ability to use Magic… let's just say that Magic was all about knowledge and Rob had given me everything that needed to known about it. While I didn't focus on it, it was hardly a shortcoming of mine when it came to my abilities.

Since the Underworld was an extremely large place that was largely undiscovered and unexplored, I managed to gain combat experience against the many different types of enemies that appeared in the Unknown Regions of the Underworld. The Devils and the Fallen Angels only occupied around thirty percent of it… and that was just one layer of the Underworld. Needless to say, keeping a low profile was pretty easy.

Still, planning, scheming and training weren't the only things I did. As an unrepentant fanboy of the series, I had almost meta knowledge of everything, having read most of the wiki articles multiple times in the past. While the timeline of events was spotty and vague at best, I still managed to develop a fairly accurate one by keeping myself aware of anything relevant surrounding anyone relevant. With my abilities, gathering information without giving myself away was extremely easy.

And finally, after seven years of being incarnated into this world, the time for me to start with plans finally came. I was as ready as I was going to be. Even though I could grow much stronger and powerful, I felt pretty confident in myself. I won't be defeating Sirzechs Lucifer anytime soon, but it wasn't like he would be capable of defeating the current me without going all out using his Power of Destruction.

"Alright. Let's do this," I said to myself before closing my eyes and holding Yamato tightly around its handle as I channeled my powers of space manipulation while thinking of where I wanted to go. While I hadn't been there personally yet, I had enough information, both meta and acquired in the past seven years through various means, to almost perfectly picture where I wanted to go. And for the Yamato, that was more than enough.

I opened my eyes and slashed the air in front of me first horizontally and then vertically, creating a tear in space which I crossed by walking calmly through it after sheathing Yamato back…

"Hello… Uncle."

… and found myself having to deploy my wings to keep myself airborne after appearing right in front of the gigantic form of Samael, the Dragon and Fallen Angel hybrid known as the Dragon Eater, who was sealed in the deepest section of Cocytus. It was so cold that I had to partially activate Incinerate Anthem to keep myself comfortably warm.

Samael was a terrible sight to see and his presence, as diminished as it was due to him being sealed, was still very ominous even if I wasn't a dragon. Possessing the upper body of a man with straight black hair, a fanged mouth and five pairs of black avian wings and the lower body of an eastern dragon, Samael was crying tears of blood from behind his blindfold and he was crucified to a cross that was even bigger than he was.

Knowing that I wasn't in any immediate danger, I neared him with a few flaps of my wings and stood in front of his face… which was bigger than what I was tall. I could clearly feel Samael's pain, jealousy, suffering, and resentment.

"I know you can hear me. My name is Calem Morningstar." At that, Samael's emotions… stalled for a lack of a better word. "You can say that I am the offspring of Lucifer and Azrael," I said and raised an eyebrow when Samael's emotions acquired a melancholic feel to them. I shook my head and proceeded. "For reasons that bear no point explaining, I have knowledge of future events. You are involved in one of them in a very unpleasant manner and I can't in good conscience allow that to happen when I can do something about it."

I paused for a moment before continuing. "I came here to kill you and completely destroy your body. Despite what you did in the past, you don't deserve this kind of punishment… no one does… but I guess that's 'gramps' for you, eh?" I asked rhetorically and my mouth twitched when I felt a minute flare of vicious agreement from Samael. I nodded at him. "You've been suffering enough, Uncle. I shall give you mercy now."

As I flapped my wings and moved back, I felt Samael's emotions temporarily shift to something akin to gratitude, relief and resignation.

Even though I did feel that Samael's punishment was beyond harsh and underserved, I actually didn't really care about him personally. That act had been just that, an act. That was my MO: seemingly kind and selfless acts that are actually done with a selfish purpose. In this case, I wanted Samael to have some last positive moments before he died… without resistance.

There was no way in Hell I was going to let Samael be used by Cao Cao and/or Hades against me in the future. They are, or will be, bullshit enough to deal with when that time came. If I can subtract from that bullshit before it becomes an issue, I will.

I fully activated Incinerate Anthem and called upon my pyrokinesis abilities as I took a deep breath and reared my head back. I gave one last look to the pitiful form of Samael.

"Great Fire Annihilation!"

And thus, Cocytus, for the first time since it came to be, knew the exact opposite of cold.

Hades POV

Hades was not a simple god.

Even though his role as the Lord of the Realm of the Dead 'gave' him the power to stand above his brothers and be considered as one of the ten most powerful beings in existence, he still resented Zeus for 'assigning' him to this part of the Underworld.

Despite knowing that he couldn't really do anything remotely sexual since he was made of bones, he still kidnaped Persephone and made her his wife and took the nymphs Leuce and Mente as his mistresses… though that was because until that day Persephone went on about being unsatisfied. He would have given her back, but his pride wouldn't let him. After thousands of years, his 'wife's' bitching became background sound. He was glad that she only spent three months with him.

He had done many contradicting and outright insane things in the past, yes, but that was because he felt both lonely and bored. Only having Thanatos, Cerberus and the souls of the dead as company could do that to you.

However, nowadays, he just felt annoyance.

Devils. Angels. Fallen Angels. During their so-called Great War, they have been supplying him with a constant influx of souls, which he had long since learned how to harness their power to increase his own. However, ever since the War came to an 'technical end' after the God of the Bible and the Four Satans, the numbers of damned souls that became part of his domain was practically nonexistent.

That was more than enough reason for him to decide to kill them all. Even though he wouldn't be getting the souls of the Angels, he was sure that most Devils and Fallen Angels would be heading to his domain once they were dead. With their souls being of an incomparable superior quality of that of humans, if he killed enough Devils and Fallen Angels it would be only a matter of time before he had enough Soul Power to challenge that bitch Hela for her domain. That'll be the day…

Even though the likes of Sirzechs Lucifer, Ajuka Beelzebub, Azazel, Michael and Gabriel would stand on his way, he wasn't exactly worried about his chances of success. As the one in charge of Cocytus, he had access to Samael. He was disgusting, yes, but that Curse Poison of his was powerful enough to significantly affect the likes of Ophis and Great Red. He could only imagine what its effects on the measly and annoying Devils, Angels and Fallen Angels would be.

That was why he was immediately and understandably worried when he felt a sudden 'heat' coming from the portion of Cocytus in which Samael was held. It took him a long moment to comprehend what he was feeling, and when he did, he used his connection to his domains to teleport to where that bizarre feeling was coming from…

… only to roar in shock and pain as he found himself engulfed in violet and crimson flames that were actually hurting him because of their Holy attribute, which was quite at odds with the properties of his own power at enough quantities and quality, which these flames seemed to have. Before teleporting away, however, he managed to feel that Samael was no more. He also managed to see a shadowed winged figure that felt both Demonic and Holy right before it disappeared from his senses a moment before he himself teleported out of there.

And thus, Hades was no longer merely annoyed. He was angry. And, after matching the energy signature of the flames that managed to burn him with the bizarre one of the winged figure he managed to sense and catch a glimpse of through the fire before they went away without a trace, that anger had a target.

Hades' eye sockets glowed with his power as he gritted his teeth. "I don't know who you are, but I will look for you, I will find you and I will kill you."

It didn't even matter that he doesn't have the slightest clue on where and how to start looking. He'll find a way… after putting out the flames that were still burning him and his fabulous robes.
