To master the Power of Destruction
Few more months passed since he started training with famous Saitama Training Regime. Of course he will not torment his five years old body with 100 push-up and such instead he started with push-up, sit-up, squad with 10 times each and run until his leg started to hurt. His body did adapted to strains but that doesn't mean he can go beyond his physical limit from get-go after all.
At first his parents were worried sick that their child will destroy his body with exessive training, but after few thorough medical checks things settled down. Seeing this he knew even if he wanted to abuse his Healing Magic to train, his parents won't let him do that. Or else they might as well prohibit him from training altogether until he is older.
"As I said, I'm alright onii-sama! My body can hadle at least this much" said Argres with fed up tone while glaring at his overprotective older brother. Which did nothing more than make him look cute to Sirzechs.
"If you say so Ar." Sirzechs adoringly said while patting his head, knowing full well he is irritating Argres further.
"Do.Not.Touch.My.Head!" as he said so he subconsciously radiated Aura of Destruction.
That day Sirzechs Lucifer learned no means no, in hard way.
>\/<
"Oh, Serafall is coming for dinner by the way." Sirzechs informed others as he sit on couch with few scraches on his face and cat form Argres chewing on his ears.
"NYAH!!!" when he heard name of Serafall, Argres paled instantly. How he managed do that in crimsol furred cat form will remain mystery.
Using this chance Satan Lucifer escaped from cluches of Crimson Kitten.
Said cat didn't even bother with his escaping brother as he decided to find a place to hide from most terrifying Satan of generation.
Last few months this particular Satan came to visit Gremory Mansion more than once. And every time she did he will be cuddled like plushie by Serafall. Argres doesn't know how things became like this, but it seems Serafall Leviathan likes him very much.
>\/<
-During Dinner-
Argres Gremory's escape was unsuccessful. His own biological father betrayed him with excuse of being disrespectful to guest.
Now group consists of Gremory Family+Satan Lucifer and his wife Grayfia+Satan Leviathan having harmonious dinner if you ignore look of extreme caution on little boy's face.
"Ne, ne Ar-chan. What do you think of Sona-tan?" Serafall asked suddenly causing young Gremory to immediately tense up.
Adults seems to be interested as well, but they didn't join the conversation.
"I think she is very intelligent girl among her peers. Has very strict but kind and compassionate personality. She will be great tactician and leader." When he started talking about someone of great potential his eyes started to shine in excitement.
After all Sona Sitri from anime was one of most underrated characters. And due to nature of Rating Game she had no chance to fully utilize her abilities. Give her thousand-man elite troops she will be able to control tide of war at will with some experience. It was no different when he met her in person, she just lacks certain amount of maturity.
"You seem to think highly of her." when Serafall said that she had large grin on her face which made Argres uneasy.
'Shit! I need to leash my fan-boying habit!' Argres cursed his big mouth.
"Yes, but she needs to be under certain amount of pressure to mature." he quickly managed hide his emotions.
"Right, right! My Sona-tan is great child." Serafall smugly said while nodding.
It seems like she is distracted, but in reality her eyes never left Argres. If she was really that happy-go-lucky person then she will be long dead in Devil's society, so all of them are façade. She hides one of most cunning minds under her semi-lunatic façade.
"So I was thinking, how about engaging you two?"
*Cough* *Cough*
When she said it Argres almost chocked on his own breath. Fortunately he had nothing in his mouth.
"Are you alright, Ar?" when he heard worried voice of his mother Argres waved his hand indicating he is alright.
"*ahem*I'm alright. As for engagement, I think it is not appropriate, since we are both heirs of respective house. And I have no intention to marrying into bride's family." he said while composing myself. And gave his parents glare that screamed 'why are you letting me deal with this lunatic? It is your job to hadle matter like engagement!' which they feigned ignorance.
Serafall didn't say anything just smiled at me. Dinner went on smoothly after that.
>\/<
Still, Serafall's proposal left him in disbelief. It is Serafall Leviathan we are talking about! She is THAT famous sis-con Satan, you know! Serafall Leviathan is even worse than his brother Sirzechs in this regard. Hearing her proposal he almost doubted whether this world was High School DxD or not. Even if his existence caused butterfly effect, this shouldn't be enough to cause this much change. Or so he thought.
But he underestimated how much presence of 'Leader' can affect society as whole. Because of his presence other children started to try harder in order to not left behind, even if motive behind their desire to catch up to him may vary, no one can deny he was cause of all this.
Not only his inborn charisma, overwhelming talent and elegance, most importantly his hard working attitude made him ideal son-in-law in eyes of many nobles. And the fact his dear older brother likes to boast about his siblings didn't help much eigher.
And due to above mentioned factors he was defined as 'Only man who can be worthy of my Sona-tan' by Serafall. Thus she has started her plan to groom Argres into her little sister's ideal partner.
Putting dark side of innocent looking Satan aside. His training is progressing smoothly. Argres is yet to start combat training since he thought it would be better to improve his physical condition as much as possible until ten.
He never understood those novels starts combat training when MC is three or four. Like, what are you learning when you are not even meter tall? Even if those guys train like madman their punches won't do much, no they will be crippled before being able to do much.
Even if there is miraculous energy like Qi and such that won't change the fact body is yet to mature. Maybe cheat race like Saiyan can handle such burden. But Devils are not really physically gifted race, they maybe stronger than normal humans but Devils are more of magical race and their specialty lays on mental aspect of magic. Otherwise Devils wouldn't have become myth as manipulative race.
Members of 72 Pillars are special case since they inherited special type of Demonic Power that grantes them special ability and enhances their affinity toward other branches of magic. So superiority of Old Satan faction is not so wrong, they just can't take full advantage of their heredity.
Moreover, to rule over others you must have more than just heredity, but those guys take it granted just because they were born with special power. Never bothering to test their limits or makes no effort to win loyalty of people they so desparately want to lead to certain death.
That's why Argrel look down on them, no they are not even worth looking down on. Even in his previous life he disdained these idiots. They had so much potential but retards wasted it with their arrogance.
And so for starters he started researching on his Power of Destruction in order to master it. Of couse under strict sepervision of Venelana. She may not look like it, but she is fearsome individual with immense demonic power and great knowledge of magic. Even if he knew from novel or read on wiki her gentle motherly side managed to decieve him. As expected Devils are natural decievers.
That aside, his research did bear some result. For example, what exactly is the Power of Destruction? It is simple actually, Power of Destruction is just hyperactive demonic energy that has property to destroy anything.
Because of hyperactive nature of Power of Destruction it is so hard to control and master. Most they can do with it is to blast it at target.
It may not look like that in anime or novel, but in reality it is hard to control Power of Destruction. It feels like you are trying to mold boiling water to desired shape. It is so hard even bordering impossible. As expected from most destructive form of demonic power. And people who can control this kind of power is incredible, even if it is to limited extent. It is even to degree he had to take back his statement toward Rias from anime being impotent, but she still should have trained in other areas, so nahh.
Incidentally Argres was born with immense demonic power and minimal amount of Power of Destruction. But as his body adapted to Power of Destruction, he evolved to be able to use it with almost negligible amount of demonic power by stabilizing it inside his body. It did lower the destructive power but now he can control it to point he can mold it's shape at will.
This bewildered both Venelana and Sirzechs, but they decided to keep it secret. After all someone who has abilty to stabilize Power of Destruction to almost serene degree was never been recorded in long history of Bael Clan. If someone outside family were to get wind of it, Argrel will become target of many noble families. They will not leave Gremory House alone with such power. Bael Clan may help… no most likely will help, but Beal Clan itself has many internal conflicts, so it is not good to rely on them more than necessary.
So even Rias never saw him using Power of Destruction, except she knows Argres have it. It is not that they don't trust her, she is just too young to understand she must hide it.
If someone were to praise Argres she will boast about her beloved big brother with great pride. But lately Rias started to complaining about Argres not spending much time with her. She started studying dilligently, but this didn't change her beloved brother as Argres continued ignoring her, so she is very sullen about it. Thus trying even harder, maybe she will confront him about it soon. At that time he just have to spark her competitive nature.
She maybe recently turned four but her mentality will match that of ten years old human child. But such quick maturity will not occur naturally from now on. Incindentally Devils have no custom of celebrating birthday, since in their long life such celebration will lose its' meaning rather quickly. Reincarnated Devils are different matter though.
Back to topic, another things Argres found about Power of Destruction is rather cliché. As his body adapted to contain Power of Destruction his cells started to change according to his power, which will eventaully lead him to be able to use it without need of Demonic Power.
Just like fish that produces electricity from their body, he will be able to use Power of Destruction like breathing. Just thinking about it makes him shiver in excitement. But this is rather slow process maybe in thousand years he will be able to use Power of Destruction at only cost of stamina. For now he will be able to use tiny amount of Aura of Destruction with almost all of his stamina, but he can boost it with his immense demonic power.
It is unfortunate rules of cultivation world doesn't work here. And his body is too fragile to intimate it as he is.
Maybe nen will help. Nen is similar to Qi from cultivation novel but wuthout 'absorbing from heaven and earth' thingy. Moreover nen is much more flexible and versatile, most importantly it orginates from user's body itself.
So no Qi poisoning, exploding from inside, meridian cracking thingy. Those are just ridiculous. Like, why bother with power that will potentially kill its's user?
Unfortunately there is no nen in this world. Technically speaking every living being has nen, it is just according law of this world nen is touki and you can't materialize chains using touki.
>\/<
"Huff, Huff. Let's call it a day for today" Argres muttered under his bearth after pruductive day of training. He likes the feeling of making steady progress even though it seems slow. But with his extreme adaptablity he will be able to run for days without stop at this rate. So why harm your body when you can become stronger eventually with steady pace?
"Ar-nii-sama!" and then voice of little girl called from behind.
'It seems, it is time to become strict brother.' thought Argres while looking at little girl with crimson hair and shiny blue-green eyes.
Looking at adorable little girl Argres have to fight a urge to hug her and spoil her rotten.
He loves this sister of his dearly, but every time he wanted to spoil her, her silhouette overlaps with that of Emily. Argred didn't want Rias to dependent on him, he didn't want to take away her chance to grow up as person. Even if she had 10'000 years to live as devil and mature, he didn't want Rias to have habit of depending on others.
But he will let Sirzechs spoil her since when his time to scold her come, she will have something to think back to. She is type to learn her own failures after all.
