DXD : Ray Gremory

So as my mother promised, she took me to our Gremory library to discuss the things I must know about magic, in order to more readily learn to control its power.

-

The purple sky shown threw the windows of our massive library with over a hundred isles of books towering to over 20 feet high.

Thankfully as Devils, light is not necessary for us, and the darkness is actually as comfortable to us, as the sunlight is to Humans.

In fact, without light tempering, we Devils become weaker in sunlight, and stronger in the night and darkness. This same thing also applies to the Human world's Vampires, who are a lot like us Devils.

The book I am currently reading says this about our Underworld... The Underworld is roughly the same size as the Human world, but with a much larger landmass, as there are no oceans, just lakes. The sky was originally purple during both the day and night, but the current Four Great Devil Kings adjusted the flow of time to match it in the Human world for the sake of the reincarnated Devils. They reproduced an artificial moon using Demonic Power and made the night's darkness the same as the Human world.

Thud! My mother placed another stack of old thick books in front of me, with a cunning smile, and sat next to me. I could tell that I was going to hate learning.

"Okay Ray, I know you are a smart boy and probably know some of the material, but we will go through it, just in-case that bump to your head made you forget, Ufufu."

"Ugh, It probably made me a bit smarter mother, so stop teasing me already."

"Alright, here and look at this book. It is called... [Why Demonic Magic Is Superior to Magic] This is the basic information you need. Then we will test your 3 magic circle skills after, so read this aloud."

I opened the heavy book and went to the introductory part. I easily read the Devil Alphabet I was taught by my mother.

"Demonic Power is something which you use to turn your imagination into actual form, and magic is something where you use equations to make supernatural phenomena occur. Demonic Power requires the power to use imagination and the power to create, and it requires having good sense. Magic is just knowledge to control equations, and you need to use your head and need calculations, so they are different even though they may seem similar."

My mother kissed the top of my head and said.

"Ray, did you know that Human Magicians magic is actually based off of our Devil magic? Now look at this page.."

Venelana points to another page with diagrams of simple Magic Circles.

"These are all three of our Gremory Magic Circles... General, Attack, and Defensive. Look at each of the pictures to understand. Most Devil houses have this similar design with colors dependent on the type of Demonic Power they have. For the Gremory it is Crimson. But in Grayfia and my case, we use the Gremory symbol, but the color of our demonic Power changes its look. So Grayfia has a silver Gremory circle."

I look at the standard General Magic Circle...

Then I studied the Attack Magic Circle...

And finally I look at the detailed Defensive Magic Circle...

As I look at individual Magic Circles, like the one for my big brother as Lucifer, I ask my mother.

"Mother, then why does our Power of Destruction not use Magic Circles?"

"Good question dear. This simple answer is because the Bloodline Powers of the Pure Blood Devil Clans are not magic. It is simply something we will into existence. It only seems like Devil Magic to non-Devil observers. So if you see a Devil use something without a Magic Circle, than it is a Bloodline ability, like Kuisha's Hole ability of the Abaddon Extra Demons Clan."

I then ask about...

"Mother, how does Demonic Potential affect both Unique Magic or augmenting Demonic Powers?"

She ponders the best way to explain it.

"All Devils have a basic set of spells we can cast and abilities common to all of us, but Demonic Potential is a limited resource we Devils have in our very Soul-Body. depending on how much strength you have, you have a FIXED amount of Potential that can never be recovered, so once used it is permanently gone."

So I use Issei's power as an example...

"For example, if I made a power that blew off women's clothing and named it Dress Break, it would use up a portion of my Demonic Potential, because it is not a common spell to most Devil's right?"

My mother looked at me funny with my question, but realized my example was correct.

"That is correct, and that spell Dress Break would cost you less Demonic Power to use, and it would be far more potent than your other Devil Magic. But why in the world would you come up with something so vulgar dear? Please tell me you won't waste your precious potential on something so useless?"

I shook my head because in the anime, it was used to save Asia Argento once. But then I ask another related question.

"So if a Low-class Devil made the Dress Break magic, and used up all of his potential on it, then when he became Middle-class, would he have a bit more Demonic Potential to work with?"

Mother smiled brightly and nodded.

"That kick to the head did help your thoughts it seems. But yes, when a Devil surpasses his limits, he does get a bit more potential. But if he saved it from earlier and not made that ridiculous spell, he could do something even greater. You, my son, already have all of your potential unlocked as a Super Devil, so be careful how you mold it to your will."

"Mother, is it better to make Magic with it, or add it to my Power of Destruction?"

She kissed my head again and advised me.

"For this topic, you need to train with your brother. He made his Power of Destruction even more destructive. But for example, you could add large amounts of Gravity to your Power of Destruction to suck in things. But to answer your question, modifying your Power of Destruction is better. You will have Servants for specialty magic in the future. So do not create useless magic like that clothing removal spell, sigh. Who even taught you that idea? Was it that Human Manga we gave you?"
