How To Survive In The World DxD With Fragment Memories

"So you finally became aware of my existence huh? Master" Masaru who heard the boy who looked exactly how he did when he has experimented on back then with Shirone and Koruka. Masaru called this boy MASA, for naming sake otherwise he would go nuts wondering who is who. "Why are you calling me master?" MASA who heard Masaru's question tilted his head, "But wasn't I simply an artificial soul made by that blob of energy... no, it should be a Grimoire Book now, I thought you already knew of this..."

"Huh?" Masaru took a step back unconsciously not of fear but real surprise, he could not understand a single thing where this is going even MASA who saw this began to smile in a sinister way. "You should know that by weakening your fighting spirit will give me a chance to devour you instead, you know?" Masaru who heard this felt fear shook within him but he controlled it by fȯrċɨbŀƴ boiling an imaginary rage almost like forcing oneself to hate another, by doing so he managed to suppress the fear temporary. "You know why I am here, but why did the book hide you from me?"

"Because your too weak, way too weak... In the soul department that is... You see your soul is human, although humans in this world can grow exceedingly strong but if their soul is not compatible with the body it will never perform it's true worth... Your currently a body as resilient as a young dragon, your strength is decent and your energy reserves are truly astounding... But because of your body, you can only put out about a quarter of your full strength because the compatibility link between a pureblood devil body and a human soul is simply disastrous. If it was not for the spellbook you would have already been gone!"

"Drago already told me about this... But you haven't told me the reason for why the book hid you from me" Masaru spoke while not dropping his guard at all, "It's for this moment, yes this moment where we will be killing each other, eating each other and the only one can survive... The one who survives will naturally be the real Masaru, you need me to fill up the cracks and holes in your soul and I need to eat you to become real instead of just a copy"

"To think one of my trials to survive in this unreasonable world would be something like this" Masaru could feel that he could operate his abilities perfectly, but the shocking thing was MASA could do the same. "I have to admit when it comes to using the Spellbook I can't use it the same as you do, however! When it comes to senjutsu your still way too lacking boy" MASA began to operate his KI within his body before sprinting towards Masaru who did the same but unlike MASA he combined his demonic energy with his Ki.

BOOM! The impact of their fists and kicks could send the ground shaking but here everything was silent, no shaking no winds. Masaru could feel the heaviness of each strike MASA was dealing against him, "You think combining Senjutsu with Demonic Energy is going to make you stronger!? That's inefficient! You use Senjutsu like this!" MASA converge the KI to form a thick aura around his fist, the moment he strikes out an illusory tiger that was life-like was materialized from the KI that was leaking through the shock force of the attack. Masaru immediately kicks the ground sending demonic energy to raise several walls made out of earth element to slow down the attack while he used trackless steps to flank the strike while heading straight for MASA who already detected him.

"Good idea to block the attack, use that strange movement to enter the subconscious mind... But you never comprehended how that Okita pervert did this movement against supernaturals?" Masaru heard MASA who met his attacks, the two of them continued to kick and hit but nothing seems to be connecting at all, Masaru felt like he was being trained but he dared not voice this out because he was not certain if the story about eating each other was true or not. But for his side it really was a devour process so it was a hard complicated situation.

"You never thought of learning more about Virtual Reality? You know Virtual Reality is a combination of Space and Illusion magic... By Combining you can temporary combine the movement set and seal your existence within the subconscious mind but this is tricky you know, you are dealing with people's awareness here and the world laws have natural mechanisms to prevent people from truly messing around with these things... You never truly exploited it all!" Masaru who heard this felt rage, "Yes, if it was not for the fact I am dealing with these creatures that can't be sampled to research and this world I have no absolute knowledge... I can only focus on the things I can do now and specialize"

"Then why not use that memory magic? Surely you noticed it haven't you? THAT magic" Hearing MASA's words gave Masaru a pause but before the incoming strike connected Masaru already retreated with ground shrink. "You.... You should know that spell that a side effect of forcing the user to enter a period of extreme ŀust! I have no need to explain why the spell does this but did you not consider the trauma it will cause to the girls!?" MASA looked at Masaru like he was looking at an idiot, "Let's first start with the girls, you should know their feelings by now so should something like this happen some of them might be bit angry but in the end it is something that's going to happen anyway" Masaru glared at MASA who shook his arms, "Let me finish, what about using Worthless and become a Eunuch then!"

'This Bas-' Masaru wanted to curse this dirty-minded boy, the fight between the two of them increased in intensity the once silent room although it did not have wind inside the kinetic force between each strike was enough to produce shock waves. "Hehehe, teasing you is so much fun! No wonder Akeno-chan loves it very much" MASA spoke but Masaru did not answer, slowly but surely Masaru was copying the operating method MASA was using his KI as his own, this process was difficult as it required Masaru to be reckless and keep being close proximity to MASA at all times.

The more Masaru gained insight the more he understood why MASA told him he was being inefficient, if this method of operating KI could be modified a bit then it should be possible. "You really are different from me, I have to study for several years to get to where I am but here you are fighting me and learning it within hours... God sure favours the talented" Soon the fight between the two of them stopped when MASA was showing signs of disappearing, "What's going on!?" MASA looked at Masaru with a warm smile, "It's because you have gained my acknowledgement.... for now"

"What acknowledgement?" Masaru was confused, but MASA smiled "Well our real eating battle will have to be for later when we can fight on equal footing, the day when your soul is healed and when the spellbook appears in front of you... Will be the day you will learn it... your existence"

"What the hell do you mean my existence!?" Masaru who screamed out opened his eyes furiously but he was in the lounge room where I was before he faced his younger self, he was thinking heavily over why would the fight stop all of the sudden? Was it really just to train him? What message did it try to give him? Was it the Book's way of telling him to hurry up with the recovery method? But he himself has no goddamn idea how!? Even now he had no idea how to emulate the stimulation effect on the soul to awaken Misla Bael!

"Onii-sama!" Shirone jumped onto Masaru hugging him tight which snapped him out of his racing thoughts, But the first thing Masary thought was the sword but luckily the sword was moved to his side so Shirone was safe. He gently ċȧrėsses her head out of a habit, "Sorry for worrying you" Angelica who was on watch together with Shirone has already left to notify the girls who were going mad on the Balls and Puppets came rushing back with great vigour.

Masaru spent a full hour to apologize to the girls who were truly worried about him, thanks to Drago who used Yui to cover the circumstances he managed to get past this situation quite smoothly. Although the cost for it was to bake sweets for the girls to which he agreed, while he was in the kitchen baking sweets he and Drago were talking Mentally.

"Just say yes or no, that spellbook has a consciousness?" [Yes] Masaru thought of using this question trick as a test but never expected it to work but what he did not realize was the Spellbook was getting impatient over something so it did not want to hide much. "When I fought my younger self it called itself an artificial soul, did the spellbook create it to control me?" [No] Masaru sigh of relief, with his connection to Drago he knew this dragon was not lying to him. "Was this rouse of devouring battle just to have me be in high vigilance?" [No, it really will happen but right now for your soul to heal you need to get nourishment from another one which the artificial soul is good enough for. I don't know when you will face it again but the next time I am certain it will be to the death, I only made you prepare for it in case this friend of ours changes their minds like now...]

Masaru places the chocolate cookies he made through combining human technique with Magic to reduce the time it takes, "Well at least I can feel a little more relieved, but to think that battle was only to teach me some applications of Ki Control to combat the side effect of a Memory Magic" However Drago thought [[Seems this brat has not realized the change in his soul....]] The dragon thought, yes while Masaru kept close to MASA to learn his Ki technique, Masaru who started to get nourishment from MASA did not notice his soul was slowly becoming a devil's soul so his power output was stabilizing and increasing but the process will still be slow but at least it's progress.

Akeno entered the kitchen, "So, have you been able to accomplish awakening your sacred gear?" Akeno came next to Masaru inspecting him, "Well I failed to awaken it, but I suppose I need some strong outside stimulation to awaken it as it did with Tiamat however a bit milder" Masaru thought about the time he once stood and talked back at a real dangerous dragon at that time, "Well at least your fine, You think you can lend me some of those balls?" Sona spoke as she stood near the entrance to the Kitchen.

"Ah sure, you can even give some to Rias HOW-EV-ER, it came from you okay?" Masaru gave Sona a playful look but Sona understood the reason, Masaru already offended Riser in the past and if there are signs of Masaru "helping" Rias then he will drag Masaru in their mess instead of Rias. "You really are in the worst position compared to me" Masaru could only helplessly laugh at Sona's point, "I blame it only my youthfulness for wanting to stand out although I really did not mean to"

Masaru spends his time chatting away with all the girls, hearing stories from Sona's peerage and their experiences he felt quite shocked to realize that the humans were just as ruthless as old devils or maybe even more so. He did not hold back teaching them a few tricks with Magic and the application of using Demonic energy in close combat especially elemental magic, Sona was the most surprised of all that Masaru would answer and teach them all but Masaru simply said if he wants to defeat his father what way would it be to create the ultimate opponents for himself.

(AN: Just so you all know, the MC has no knowledge about the Azazel Cup... So he is still under the impression that the Rating game will only be for devils)

Diehauser, Diana and Julia finally returned from their vacation while Sona and her peerage returned to their home, with his mother and sister back the liveliness of the house was no less than before.

"So, please make sure to make your teams for when we will be leaving for Kyoto. It will be three days and two-night trip so please make sure to buy the necessary items indicated on the list!" The teacher announced before leaving the classroom, Masaru leaned closer to Barold. "You want to partner up with me?" Barold nodded, "I think it will be better for me too since the two of us are the only two guys among all those girls" Masaru agreed with him completely, "Yes, but what location you think we should visit?" The two of them started to work out a journey trip together but it would later be intruded by girls who refuse not to take the chance of a holiday with Masaru. Poor guy, what comes around goes around they say.

With the classes over it was finally time for Club activities and Masaru had an off day today so he headed straight for the Kendo club, seeing Sakura wearing only her black hakama with her wooden katana Masaru went to get changed and armed himself with a wooden katana. "So you already formed a group for the incoming school trip?" Sakura fended off his sword strike while launching a counter that ended up being blocked by Masaru's handguard of his katana. "Well I formed one with Barold but later the girls working together with me in the Disciplinary Committee also joined"

"You really are a womanizer" Masaru who heard this shook his head "No no no no!!! Stop it!!!" Sakura was surprised by his swift movement dodging all her strikes then appearing behind her back blocking her mouth with his hand, "Don't say it out loud, I am not a womanizer" Sakura looked at him with scorn, when he moved his hand away she spoke "But you taken liberties with me" Masaru blushed while taking a step back not expecting this result because it really could be seen as she said "Ah... Sorry?"

"Haaa... I was going to invite you but---" Masaru interrupted her, "I was also thinking of inviting you" Sakura looked at him with surprise "You already got those girls following you" Masaru shook his head, "Even if they follow me I am but a guy, there are topics guys and girls don't share... Besides I want you to get to know them first" Sakura was a bit confused, "You want to use me as a shield or something?" Masaru shook his head, "They all grew up together, so having a new friend to talk with will do them good."

"Fine..." Sakura pouted feeling a bit down as she hoped he would invite her for a different reason, it has been a few months and the two of them kept sparring to the point she enjoyed her time together with him. It was almost like he was made for her, she could hit him with everything she learnt from her family and he would take it on without backing away. It was only natural that a curious interest would be developed into a crush, she was not certain whether she loved him or not but she was certain she held an interest towards this boy named Masaru Belial.

Soon the two of them resumed their daily spar of pure techniques, Masaru could see her progress in learning techniques from him was quite amazing as the two of them were similar after all. Learning through combat was their trait and strongest point but also their weakest, Masaru stepped forward using a jujutsu move to disarm her while tossing her over his shoulder stopping the match. "You cheated!" Masaru smiled "If it was a real match you would have been dead, from now on facing me as you would in a real fight" He helped her up while he left her alone, 'Real Fight? Masaru... Are you training me for something?' Sakura thought since she was always suspicious about why Masaru would train her, she was firmly taught by her grandfather that there is no such thing as free lunch. 'Well, I will hear him out when he decides to talk... If I can I will not mind helping him out'
