Won't make same mistake again

[User's body is now ready for intense training]

'Now, I'm ready, huh? Let's start training from tomorrow.' Argres decided as he continues to staring at the sky in shade of apple tree near Gremory Mansion.

It has been four months since his memories of first life came to him. In four months he has been doing ligth exercises, training his mental strength and sensory abilities in steady manner.

Now he is on his way to acquire Eidetic level memory, currently construction in-process Mental Palace, information processing speed that is 1,3 times faster than avarage devil's and finally something similar to Observation Haki.

At first he thought he can focus on his sensory abilities but his newly enhanced senses were taking toll on his young brain. So he had no choice but to practice other mental abilities at the same time at steady but slow pace.

'I should have listened warning from UTS.' that was first thought after he almost collapsed due the overloading his brain.

Effect of his new sensory ability, Observation Haki as he is calling it, is same as one in One Piece. It allows him to detect persence, roughly guess his surrounding and vaguely know intention of others. For exaple if he were to try he will know how many living beings in hundred meters range, he will be able to walk blindfolded without tripping and allow him to dodge when his overprotective older brother wants to pinch his cheeks. Last is possible because his older brother never hides his intention when Gremory Family have their family time.

And his Mental Palace is being built with classical library design with separate hall that dedicated to his memories from previous life, another one for his collection of anime, manga, novels.

He intented to spread Hol-… I mean Demonic Scripts to crush the show of that Barbarian(Issei) in order to protect future children of devil race. If need be he will be gladly lead such Hol-… Demonic Crusade to slay that Heretic Barbarian.

And Entertainment Industry in Underworlds will be lucrative, since Devils are long living race, their greatest enemy is boredom.

'Bored Devils are most dangerous Devils.' this is cunclusion he came to when he skimmed through High School DxD novel.

In his opinion Rizevim Livan Lucifer was bored enough to abuse his family, bring chaos to world and set free World Destroying Abomination then seek way to Another World, without thinking about consequences. If person lives longer than Christian Era then they will come up with some crazy, world destroying idias sooner or later. That's why majority of upper echelons of Supernatural societies has few screws loose, his older brother is no exception to this Universal rule.

-In study of current Lucifer-

*achoo*

"Did you catch cold, dear?" silver haired maid asked worriedly. For Devils catching cold is serious matter after all.

"No, I think my lovely siblings are thinking about me." Sirzechs said with happy smile.

"Now, let's finish this Abomination of Paperworks, so we can see my lovely siblings!" then he proceed to massacre page after page with great determination.

Seeing this Grayfia couldn't help but sigh helplessly, but small smile can be seen on her face.

>\/<

-Back to Argres-

So he decided to bring Dawn of Entertainment to Underworld with cooperation of certain Magical Satan if possible.

'Muahahahaha!' just thinking about it makes him want to cackle like third rate villain.

"Young Master!" then cheerful voice of maid snapped him out of his great plans to become Demon King of Entertainment Industry.

'Oh, shit!' Argres can't help but curse inwardly while hurriedly standing up. Even if he can detect presence witin hundred meters range he still can't notice arrival of strictly trained maids of Gremory House.

Then he the proceed to looking for escape route. But it was too late as he was surrounded by small army of maids.

"It is time for your etiquette class Young Master!" said young maid who was leading others with bright smile. She was quite beauty looked around in her early twenties with black hair, brown eyes. She was maid in charge of his daily needs since he can remember. He never had chance to know her name.

Argres stared at her for second then simply said "I refuse!" with perfect poker face. Argres Gremory hated studying such trival matter even before he got memories of his past life. Now he has 30 years worth experience, this particular trait of his became even stronger. As result situation like this became daily occurance in Gremory House during past few months.

"It is better to read books if I want knowledge. And learning etiquette is meaningless to me." said Argres matter of factly.

What he said is true. Since he has 'Natural Grace' from birth, his every movement was graceful, no his very existence is graceful. He has no need to study such thing.

But maids turned deaf ears to his valid argument. He was brought down swiftly with superior numbers and dragged to study where his teacher was waiting for him.

-One hour later-

After session of pointless and boring to bone etiquette class seasoned with praise from old man, Argres is comfortably sitting on coach in library, reading book about business. Not far from him small pile of books that he planned to read today can be seen placed neatly.

Then peace in room has been disturbed by entrance of lady with shoulder length flaxen hair and violet colored eyes, looks much like natural born Bael Clan member.

She was Venelana Gremory. Madam of Gremory House and now mother of child in frond of her.

"Argres, dear I heard you refused to accompany Ria to play date, again." Venelana asked gently from her child.

Play date is event where direct descendants of 72 Pillar gather, play and most importantly let them experience social life during their childhood. Such event was idea of Serafall Leviathan, reason being since population of Devil race is low it is beneficial to make effort to stay united… but from what Argrel remembered from anime this plan didn't seem went so smoothly or this was just Serafall's excuse to spread her Magical Girl show. Incidentally this event used as social gathering for nobles who came with their children.

"Yes. I deemed such activity as unnecessary for my future. Children of my age are not mature enough to understant my thought process and benefit of relationship formed during such period seems minimal. And most importantly there is no such individual that can worth spending most of my day to build relationship with." Argrel said casually with no expression as he put down the dook.

That is result of his previous experiences. Usually children of this age will be busy babbling some nonsense and breaking their toys, even if child of devil race mentally matures few times faster, it is not enough for them to consider forming connection with other noble houses. As result he deemed if he doesn't want to form geniune, long lasting relationship then going to such event is unproductive. And he found no such person who he can form long lasting relationship with from his past experiences during his days in play dates.

Thus political situation of Children of 72 Pillars is in dire need of leader to stay united and conflict between Wooden Sword, Fluffy Plushie and few other minor factions are intensifying by day.

"Besides if I were to go there and steal chance to be in limelight from Rias, then her already forming inferiority complex will turn to worse. And she needs to mature and form her own circle of friends." said Argrel as he remembered his adorable little sister.

Rias Gremory is naturally energetic girl with natural charisma, it is just she was being overshadowed by her older brother. Maybe being leader comes naturally to Gremory lineage, since they are famous for being loved by their subjects and from what Argres remembered in anime Rias was able to keep her peerage together even though she was impotent, pathetic excuse of King.

'I have to make sure my sister does not become Rias Gremory from anime.' he silently swore. But he will let her act as spoiled princess until Rias loses to Riser since it is good chance to let her to experience loss. Even now she is type to learn things from her own failures rather than take advise from others.

If she asks help from him, he have more than one way to get her out of engagement. If not then he will have to rub harsh reality on her face so she will almost marry Riser, but without Issei to save her. Since Argres wanted her to stop depending on their overprotective older brother, it will defeat the propose if Rias just changed who she is clinging to.

Hearing her child Venelana can't help but smile wryly. She just wanted her so-called ideal heir of noblity to have some friends. But her child didn't make friend, Argres made followers. He was too excellent to be considered equal and his charisma was too high to allienated, as result children started considering Argres as their leader subconsciously.

"Come, Argres let the mother spoil you." Venelana said as she embraced her son.

She is usually strict mother who rarely spoils her child. But that was because strictness was necessary for growth of her chilndren, with personality of her husband and eldest son this role inevitebly fell on her shoulders. However with Argres she doesn't need to be strict, since he was sticter than anyone on himself.

"But this is not necessary mother. I am alright…" Argres wanted to assure Venelana but tears inevitebly rolled down his cheek.

Having memory of past life didn't make him man in child's body. After all, it can be said Robert MacGregor is maturing again as Argres Gremory. Right now he is extremely mature child, but child nonetheless. So, being leader may sound attractive to some but for little boy who just wanted to make friend, this is plain heart-breaking.

'Maybe this is how Gilgamesh felt. But he had no mother to console him. Nah, probably not.' thought Argres, starting to respect one of characters he hated in his first life, but he was too proud to acknowledge.

Thinking so he buried himself deeper in his mothers embrance while he silently cried. He was too proud to let others hear his sobbing.

"There, there." Venelana rubbed her child's head gently with complicated expression. As madam of noble house she was proud to have such excellent child, but as mother she felt it was not worth it if he has to suffer because of that.

After he cried his heart out he kept his face in his mother's embrace while blushing furiously. After calming down he was too embarrassed to face his mother. So he decided to take most rational action in such situation.

He decided to…

*Poof*

… transform into cat.

"Fufufufu, you still have habit of transforming when you embarrassed, huh?" she can't help but chuckle her now turned into little kitty son.

"Come! Who is mama's little kitty?" Venelana started petting crimson kitten with blue-green eyes on her lap.

This is Argres Gremory's habit before he awakened his memories. He usually transformes to various kind of small animals when Sirzechs and Grayfia teases him too much and sulks on his mothers lap. This proved he has incredible talent for Transformation Magic… but within Gremory Family this habit of Argres served as one of very few material to tease him.

*purr*

Argres subconsciously started purring until he realised he was being treated as kitten.

"Stop-nya!" he protested with sharp voice but his mother ignored his protest and proceed rubbing his ears making him sleepy.

"Nya! Stop-nya! Please nyastop(nyamero)!" Argres struggled to get out of cluches of his mother with all his might.

"If you have problems please don't hesitate to tell mother okay? This is what family is for after all." said Venelana as she rubbed her cheek on her little kitten.

"Y-yes.." was only thing he could say as he blushed slightly. Fortunately he was in cat form, so no one saw his blush. And so Argrel let his childish side free at this occasion.

After that he ignored Venelana while pouting for a while, however.

After their little mother-son bonding, they sat in library in comfortable silence. As Argres was reading book while sitting on his mother's lap, he felt comfortable and safe.

'This… this is feeling of mother.' Argres thought while enjoying feeling as much as he can.

In his previous life he was real trouble maker, even his father gave up on stoping his daily pranks. But his mother was still able to ground him for months. Mothers are such fearsome people, they can turn most fierce man into guilty little brat. So after he lost his mother, he was devastated beyond recovery.

Now feeling Venelana's maternal love, he almost melted into little puddle of joy and shyness.

>\/<

"Will you come with me to see Ria, Argres?" asked Venelana as she looked at her son. She was going to welcome Rias as it was time for her to come back from play date with Zeoticus,

From Venelana's observation Argres loves his little sister dearly and clearly expresses his care for her but keeps his distance so he will not affect her self-confidence and growth, so Rias will not depend on him too much, more desirable than his overly doting father and brother. It did help as Rias clearly knows her older brother loves her but she doesn't cling on him too much. But that didn't save Rias from developing bit of inferiority comlex toward Argres though. Fortunately it is is nothing serious for now.

"No, I will be doing some light exercise and go to sleep. Tell her, she is not worth my time." if she is going to develop inferiority comlex, even after all he has done, then Argres is going to be person she wants to surpass with her all.

Since her complex is not serious yet, he is going to change that feeling of being inferior to him to that of wish to prove him wrong. Since he obviously showed affection, she is going to do everything to feel that affection again. Little sister he knew is that kind of stubborn but compassionate girl after all.

He is not going to make mistake he made with Emily again. Because of her overly clingy attitude toward Robert, when he left her to fend for herself she made many mistakes that ruined her life. True, it was irresponsible of him to leave her like that, but it was still her own choice that led to such unsighty result.

"Argres, dear…" knowing what her son wanted to do, Venelana couldn't help but feel pain. After all raising child was parent's duty, watching her son doing his best for his sister she felt she has failed as mother.

"Don't worry mother. And when I started training seriously I will not have much time to spend with her, anyway." Argres told his mother as he left library.
