4 A Day In the Life of Asterius Belial

"97, 98, 99, 100." I finished.

I then stood up from the ground after completing my push-ups and stretched my arms into the air.

It's another beautiful day in my new life, and at the moment I am completing my morning workout routine.

100 push-ups

100 sit-ups

100 squats

100 crunches

And finally a 10-km run.

Now ordinarily this workout would be nothing for me. A devils physiology makes them a lot stronger and more durable than normal humans, and my body more so given my circumstances. Because of this I add a little something extra to this workout routine.

Namely I apply gravity-seals to my body while doing my workout routine.

It's a bitch, but doing it this way builds my body even more. Also since I am not wearing actual weights my growth and development isn't being stunted.

It's a win-win situation.

I should also mention that once I get used to a certain weight when completing the workout, I up the weight size and start all over again.

I've been doing this since I started my martial training two years ago.

At first I started off easy at 5kg. But now after two years I am up to 50 kg across my entire body. Asking for that unlimited growth wish really was ingenious.

Thinking about it I put a smile on my face.

"Aster, why are you smiling like that?"

I turned to my left to face the person who asked me that question.

She is a girl my age. She has blonde hair in twin-tails and light blue eyes. She is also wearing her usual stoic expression on her face Her name is Angelica Ainsworth.

She is my best friend.

Well my only friend at the moment really.

That thing about devils having low birth-rates is no joke. Angelica and I the only children in my family's mansion at the moment besides baby Diehauser. There are other children in the Belial territory, but they are spread out and since I am the heir I cannot call them here just to play with me.

Their parents wouldn't be able to make the trip, and I am not some young master that will abuse his power and force people to be in my company.

So that's why it's just me and Angelica. But she really is my best friend.

Her parents Erika and Darius are close advisors to my father and have been since he took over the territory from my grandfather who died right as the Great War ended 40 years ago. Angelica's mother is even my magic and demonic power teacher. That's just how much my father trusts them.

I grinned wider at Angelica. "No reason. Just enjoying life." I told her.

Angelica nodded. "As usual." She mused.

"Yes, it's the same old me." I retorted. "But enough talk. Let's continue our training." I said.

"Yes, let's." Angelica said.

The two of us then started our 10-km run.

Angelica keeping up with me the entire time. Which actually surprised me.

When we first started training together two years ago she could barely touch me. Now, she's running right along side me, using 30kg gravity seals on her body. And she isn't even a member of the 72 pillars or one of the Extra Demon clans. No, Angelica and her family are common devils that have lived in Belial territory since its inception.

It just goes to show you how truly prideful and idiotic most pure-blood devils are.

Common devils may not have clans traits are innately high demonic power, but given enough training and resources they can be just as formidable. But the higher-ups and old nobles are so afraid of losing their power, they do all they can to keep common devils down under their thumb. It's the same with reincarnated devils, who only have it slightly better since they have more chances to increase their standing because of the system in place. Still though, things aren't that much better for them.

But once I start coming into power things are going to be different before people even realize it.

I wonder what those old farts will say when the devils in my territory begin to outshine the devils in the territories others of the pillar clans?

When their faces drop I will record it. That way I will never forget the sight.

But that's far off in the future.

Right now I need to look at what's ahead of me.

Namely trying to find a way to increase the wealth of my family's territory and getting strong enough to survive the Civil War in a couple of decades. I also need to find strong allies who will stand with me.

It's never good to try and do everything on your own.

Also when Ajuka comes up with the evil pieces system I want to be able to get strong peerage members right off the bat.

Like Angelica.

I have already decided to make her my queen.

In more ways than one.

I've seen her mother who is a beauty, and Angelica is already starting to develop quite nicely.

Devils mature a lot faster than humans after all.

So in a few years when we are both of age I will eat her up, and she will become my woman. Well my first woman since I plan on having a harem.

This is DxD after all. Not having a harem in this world would be sacrilege.

But more importantly I would be disgracing myself as a man of culture if I didn't go for it.

However just to be clear I am not going to do anything to Angelica right now. We are both only ten and I am not a lolicon.

Besides I don't want to the FBI to break down my door. Those guys have spider-sense when it comes to stuff like that.

No thank you.

Moving on, Angelica and I finished our 10-km run in 20 minutes.

A new record for us.

Once we finished our run we went over to the wall and collected our towels to wipe the sweat off our bodies.

As soon as we did that we headed back inside the mansion, since we on one of the training grounds used for the soldiers.

After entering the mansion Angelica and I went our separate ways and I headed to my room. I then went straight of the shower.

Yes, Devils already have shower technology.

They really are amazing inventors.

Anyway, after completing my shower I moved to get dressed. Once I did I went to check myself in the mirror. In doing so I marveled at my looks like I had done quite a few times before.

I don't mean to brag, but I am a looker.

I have the grey hair of my father, and the dark-blue eyes of my mother. I also have slightly-pointed ears courtesy of my Belias genes. But more than that I also have dark-blue strands of hair interlaced with my grey giving me an even more exotic look.

I once asked my mother about my blue hair, and she told me its' not-uncommon for devils like me with rare amounts of immense power to experience genetic mutation and changes. I just rolled with it since it explains it all.

After admiring myself in the mirror for a moment I left my room.

The moment I did was greeted by a man in the butler uniform.

He has short black hair, with a single strand of red resting against his forehead. He also has black sclera with yellow irises holding a tinge of red. This names name is Diablo Noir.

And before you ask me, no this is not a crossover world of some kind.

I already checked.

Though it looks like characters from other anime series are lurking around here. I'll have to investigate that further in the future.

Anyway back to my Diablo.

He is my personal butler/attendant. As well as my bodyguard. He is a common devil from the time of my grandfather who rose through the ranks because of his skill and battle-strength. He has been serving my family since my father was a baby and even helped raise him. Now he is watching over me.

I couldn't ask for a better companion.

Not only that, he is one hell of a butler.

"Young master Asterius, I see training went well." Diablo mused.

"Yes, it did. Angelica and I beat our record today during our 10-km run by a whole five minutes." I explained to him as we started to walk towards our destination.

"Excellent. You are growing more powerful every day. The master and mistress are so proud of you. As am I." Diablo spoke.

"Thank you." I told him.

He then nodded.

The two of us chatted a bit more, but eventually we reached our destination.

Just as we did Angelica also arrived, freshly bathed and in new clothes. She bowed to Diablo. "Sir Diablo, a pleasure as always." She said, raising her head.

"The same to you young mistress Angelica." Diablo replied. "This is where I take my leave. Enjoy your lessons as usual." He said. He then walked off.

The moment he did the doors to the room in front of us swung open.

Angelica and I entered not batting an eye. That's because this happens every time we attend these lessons.

Which are magic and demonic power training with none other than Angelica's mom herself.

Once Angelica and I crossed the threshold the doors closed behind us.

Inside the room multiple tomes and parchments are floating through the air, rearranging themselves on the massive shelves.

Meanwhile sitting at one of the rooms many tables is a woman. She has blonde hair, blue eyes, the same stoic expression as Angelica, and is wearing an all black dress.

That is Erika Ainsworth.

Angelica's mother and a first-rate devil magician.

My father even told me once that Erika received praise from thee Mephistopheles himself.

Though it's not too surprising considering she created her own type of signature magic.

It's known as [Flash Air]. It's a type of spatial magic that focuses on displacement. Moving one thing to somewhere else. I know that seems like regular teleportation magic but its not.

From what my parents have told me Erika's magic allows her to displace anything and everything. Souls from a body, the position of buildings, attacks aimed at her person, even the space surrounding her opponents. She can dodge just about any attack, and turn just about anywhere into an impregnable fortress.

This magic is no joke.

I even asked if I could learn it, but I can't.

Apparently to use [Flash Air] one has to have an innate talent in spatial magic, and be able to process the displacement vectors of whatever they are displacing to an extremely fine degree. Also to displace things like a soul the caster must understand soul magic to a fine degree, otherwise it won't work.

Basically [Flash Air] is for more magician-focused type fighters than someone like me who is trying to become an all-rounder.

Which is fine.

The more diversity in my allies the better.

Angelica is learning her mother's signature technique, and at the moment is the only one who is. So when she masters it she is going to be a beast.

The two of us walked up to Erika's table.

As soon as we reached it she put a small smile on her face. So did Angelica.

Like mother, like daughter. The two of them are usually kuudere's. But if you know how to read the slight changes in their expressions you can tell what they are thinking. It's also incredibly cute when they do display their emotions.

"Mother, good morning." Angelica spoke.

"Teacher, a good morning to you." I said.

"Good morning to you both." Erika said. "We will be continuing the same as yesterday. Angelica come with me." She said.

"Yes mother." Angelica answered.

The two of them then left the table and walked off further into the room.

Which is Erika's private workshop by the way. My parents let her build it in the mansion given all her contributions and years of service.

Anyway, while mother and daughter went off to practice their secret technique I pulled up a chair and sat down at the table.

I then reached into my pocket and slipped on a pair of glasses.

I then adjusted them using my fingers.

I don't need glasses, but they make it easer for what comes next.

Reading and studying.

It's part of my training.

The clan trait of the Belial clan [Worthless] allows one to invalidate the special abilities and powers of just about anything. Making it extremely versatile and powerful. It even works against the clan traits of other devils. But there is a huge catch. To be able to affect something with [Worthless] the one using it must understand the properties and characteristics of whatever they are trying to invalidate to a fine degree, otherwise the power won't work.

Hence why bolster the strength of my [Worthless] clan trait I am starting off my reading books. These books have details regarding countless magics, magical creatures, magical items, even some data about other devil clan traits, and so on. By reading all of this I can come to better understand all these things, so that when I encounter them in real life I can nullify their powers with ease.

Of course it won't be that easy.

First I must gain the knowledge, and then practice using my Belial clan trait. Only then will I grow in strength.

But it's as they say: The Long Journey begins with a single step.

And this is my first step.

I am also not shirking learning about other magic forms either. Erika will get started on that in about a year or two.

Then there is my Belias clan trait [One With Nature].

That's actually a lot easier to deal with than [Worthless]. I have tons of plant-based techniques in my head from the various anime, manga, and cartoons I watched in my last life. Some of which I have already started working on.

Devil magic is based on imagination after all. And I have plenty of that in my mind.

I can't wait to pull a Hashirama and create a mutli-headed wood dragon or a massive forest in the future.

I also can't wait to create vines that will attack women and play with their bodies. I am already starting to think up acid vines, or ones that release a potent aphrodisiac.

"Ku, ku, ku." I chuckled, licking my lips.

Those female enemies better get ready. I have seen a lot of tentacle hentai and I am not afraid to use that knowledge to crush their soles.

Mhm, how glorious it will be when that happens.

I also feel no shame in doing it either. In fact I want to relish in their agony.

I am a sadist after all.

I discovered it quite some time ago. I mean I always had sadistic tendencies back in my last life, but ever since being reborn they have only grown and my mind doesn't feel remorseful when thinking about committing such acts.

I soon realized it was because I was no longer human, but was a devil. In both body and mind. I slowly began losing normal human morals.

But that is fine. I was given this chance to live again and I don't intend to waste it fretting over something that isn't really relevant any longer.

I am not a sociopath after all. I still love.

I'm just getting in tune with what I am now.

A creature of sin.

Putting a smile on my face I pulled a book in front of me and opened it to the first page. I then activated the magic in my glasses allowing me to speed-read all the information and keep it retained in my head.

I truly love magical technology.

Plus with these glasses I can now pull off the perfect Aizen impression any time I want.

Yes, this new life is turning out better than expected.

Finishing the first book within five minutes I moved onto the next one.

The moment I did I saw information about a species of carnivorous plants that put their host into a dream-like state to eat them.

It's a lucky day for me.
