"Sirzech-sama, there is a request personally from Diehauser Belial" A Silver haired maid came into the office where Sirzech was currently working on documents and reports related to the Naberius Family incident, "Oh? Did not think he would send one since he found his son after all" When Sirzech opened the letter reading it his face slowly began to cramp up before sighing, "What''s wrong? Did he do something again?"

    "No, he requested for Guardianship over the Nekomata girl because his son and the girl are quite attached to one another" Despite being a bit sad he lost a peerage candidate for his sister, he still felt it would be better for the girl to be with the boy in order to recover from her trauma. "But wasn''t the plan to---"

    "No, the boy and girl does know each other. Okita''s report is also attached. sigh... I will have to find another potential peerage member for my sister as a gift. Process the guardianship for the girl" Sirzech smiled wryly while handing over the letter for Grayfia who was his Wife, Queen and Personal Maid to process the necessary documents since he was busy with other things. ''Wonder if I should ask Beowulf if he knows of someone... Or perhaps Enku''

    /

    It has been a week that Masaru and Shirone stayed at the hospital recuperating till they were finally released, thanks to his father, Shirone was now under guardianship of the Belial Family under the premise that she would become a peerage member of Masaru''s peerage. The reason for the additional condition Diehauser added after talking with Shirone alone was the fact during the tests Masaru undergone at the hospital to check his conditions, they realized his bloodline was pure devil which was the reason they stayed at the hospital for a week instead of the original three days.

    Because of the experiments Masaru undergone his body constitution was stronger than average hig-class devils and his magic reserves was enormous, if he was not the son of Diehauser Belial he might have been taken away somewhere to experiment on him again. It was also during this period of time that Masaru became able to call out his Sacred Gear which was a Grimoire he named Singing Spellbook, the reason he called it that was the fact the sacred gear was simply a medium and memory storage filled with spells allowing him to use spells of various origins. The only downside was that his current base could only handle basic spells and the limit for summoning the grimoire was three hours.

    That sacred gear was the second reason the doctors might have pulled him back for more tests in hopes to see if pure blood devils could gain sacred gears naturally, but thanks to his father''s coercion the doctors reluctantly released him after a week and now he was currently near the Manor where the Belial Family Houshold is at. "These are the lands of the Belial Family, in the past we did have financial difficulities which was one of the reason I could not see you and your mother. But with things stabilized I was able to search for you full time with my peerage"

    "Wow, I prefer this natural state compared to other regions where there is too many buildings" Masaru was looking outside quite enjoying the sight of the underworld, it was truly different compared to the Earth, he was granted a second life and now he has the change to travel around so he felt excited he could do a lot of things. But those plans came with a price that he needed to train as there was currently no peace between the three factions just yet, so to survive he will undergo training with his father and when he is 10 years old he can finally receive his Evil Pieces.

    When he heard that he became a pure blood by pure luck because of the experiment turning him into a potential Super Devil he rejoiced thinking he could put up a decent team which increases his chances of surviving in this world. "I am glad you like it, we also prefer to keep most of our lands similar to farms provided staple food for the devil race as well as services that requires the Worthless ability"

    "Do you think I can also use Worthless?" Masaru was quite interested in this ability after he heard from his father, as long as he understood what the thing is composed of he could simply deem it worthless which is similar to a disintegration or alteration magic, with his Sacred gear he has a chance to learn a scanning magic that could work like wonders together with this ability, "You have the attribute, so you should be able to but don''t use unless I am around okay? That power is dangerous if it goes out of control"

    "Yes Father" Shirone was currently sitting quietly next to Masaru, the current surroundings was truly comfortable for her due to her racial abilities: Senjutsu. During the week she stayed with Masaru, she learnt the truth behind her sisters act and why Kuroka never told her. She gained motivation to become stronger together with Masaru and gained enough achievements so she could change her sister''s fate with the Devils, this was a plan she and Masaru both spoke about.

    But her other main reason was she needed a reason to stay with Masaru in a way they would never separate and Masaru''s Father Diehauser gave it to her, with everything set she felt more alive compared to the hell she went through. "Uncle Diehauser, will the family accept me?" Because of the rumours of her sister, Shirone knew that people were avoiding her in fear that she might rampage. Masaru told her not to mind it as it was normal for the weak to fear the strong, it will slowly fix itself but she could not help but feel nervous that they were now going to meet Masaru''s family.

    "Don''t worry, everything will be fine" ''Sigh... Just hope that Sister of mine does not do anything crazy'' Diehauser could only smile wryly at this little girl he came to know this past week, he felt relieved that his son has someone like her at his side during all this time and also agreed to be on the look out for the elder sister to help. "No need to worry Shirone, your my family are you not?"

    "I am!" Shirone pouted feeling that Masaru was purposely teasing her, but she could feel much calmer than before. Masaru smiled at Shirone''s adorable pouting act, he ??r?ss her head causing her to unconsciously purr with her pleasant face. The Relationship between the two grew even stronger ever since the incident and Masaru could only thank the mysterious forces that brought his current circumstances.

    /

    "We are here" Diehauser spoke suddenly causing both Masaru and Shirone to stiffen a bit as both were nervous to meet their new family, one of the butlers that came to welcome them opened the door allowing Diehauser to walk out first. "Welcome Home Diehauser, it''s good to see your safe and sound" a Lady who had similar hair hair as Diehauser came walking over fast and embraced her son lovingly, while a man who had a similar face as Diehauser came over while resting his hand on his shoulder "It''s good to see your back"

    "Huh!? Why did he call me out first but instead for my wife" Lord Belial the father of Diehauser felt disheartened at the fact Masaru called out his Grandmother first unlike his father, Calfa who heard this snorted "Of course he would greet me first, your grandmother''s grandson aren''t you?" Masaru nodded without any hesitation as he knew in any family gaining the favour of the grandmother would lead to victory, "You--- I will not give my grandson to you!" The two grandparents were now arguing with one another but the servants could only smile warmly at this family who underwent multiple hardships and it was thanks to Diehauser than most of it was finally brought back together.

    While the two were arguing another young lady who had a similar looks to Calfa Belial appeared and snatched Masary from her arms hugging him, but she did not stop and even went to snatch shirone who was too stunned to even realize what situation she was in. "So cute!!!! I have such a Cute Nephew and he even has such a adorable fiance''" Masaru and Shirone who heard this both blushed causing the lady to Kyaa Kyaa even more.

    "Cleria..." Diehauser sighed at his sister who flew off to another realm hugging his son and Shirone, even Calfa realized there was yet another visitor and immediate registered ''Fiance'' Cleria mention but she still fumed with anger that her grandson was snatched "Cleria, since when do you grab things from me without introducing yourself?"

    "But you did not introduce yourself either" Before the two ladies were about to have their daily round of talks Lord Belial came between them, "Well we are outside so lets go inside first" When the ladies heard this they reluctantly agreed and everyone went into the Manor, Masaru was once again introduced to his new family members including his Aunt Cleria Belial.

    They asked Diehauser questions and he began to tell him most of the experiences Masaru told him about when he was kidnapped. If it was not for the fact the Belial Family''s current standing has only recently improved even better then they might have gone and cause another round of chaos, the family was smaller compared to others but they loved and cared for each other more than ever.

    This was proven when Calfa told her husband that there was no need for a tutor for noble etiquette lessons as she will teach him and Shirone herself, they already knew Diehauser will be training him and Shirone personally. His Bishop Circe & Julia will be training Masaru in Magic because of his sacred gear while they will look for a Senjutsu expert who can train Shirone which will most likely be a yokai.

    "To think the child''s education would be arranged in a single day, this would not have happened in the past" Lord Belial looked dazed at the window thinking about the past, Calfa who knew of this could only nodded as a tear form at the corner of her eyes "From now on we will allow our future generation to have a better life..." Diehauser and Cleria both knew about it as well and felt happy, Masaru however never knew his father had monsters in his peerage. Each member was truly unbelievably Amazing and their history was even more so.

    /

    "Come, hit me harder!" Diehauser was currently sparring against Masaru, although it was early according to the grandparents who wanted to doted a bit more on him but Diehauser was strict saying that training was suppose to happen two years ago but luckily Masary trained in Senjutsu during that period and the experiment that transformed his body which Diehauser wants to exploit all that potential and push his son''s strength even higher.

    "Let''s do this!" Shirone nodded at Masaru before the two of them blast off towards Diehauser attacking him together, this time Diehauser was having a slightly difficult time compared to his easy going time because the synchronized team work between Shirone and Masaru who trained together under the tutelage of Kuroka was now displayed to Diehauser. ''Individually they have flaws but when together these two cover each other''s flaw as if it was a instinct, how amazing'' After a exchange of punches and kicks, Masaru and shirone was send crashing into the ground once again.

    "Haah ---- Haaah" Masaru was gasping for breathe while looking at his father with scorn for being a spartan trainer, the looks of a father was gone and was completely replaced by a instructor. "If your not coming then I will" Diehauser tap the ground lightly with his foot sprinting towards Masaru who flinched, he raised his fist to attack Masaru''s ?h?st but Masaru himself unconsciously sidestepped while infusing his Ki within his body to give him a short burst of explosive strength.

    "Not bad... Guess we can end it with this for today''s training" Diehauser smiled at Masaru and Shirone who collapsed on the ground from exhaustion, it has been ten hours they have been sparring endlessly so he could test how long his son can last while taking beatings but he was even more surprised at the potential of the Nekomata which made him even more glad he convinced her to become part of his son''s future peerage. While he was still thinking the back of his head was smacked by a woman who wore a white robe was running past him, she was Julia, his bishop.

    "Geez Diehauser! Why are you so hard on Ma-kun!" Julia puffed her cheeks pouting at Diehauser while healing Masaru who was still laying on the ground, Diehauser could only smile wryly thinking after his peerage met with Masaru they became a bit more lively instead of their serious side. "Julia-oneesama" Masaru muttered softly causing Julia''s face to flush up with happiness for having such a adorable little brother, soon that happiness faded into a slight anger as she glared at Diehauser, but Diehauser himself looked at the sly smirk on his son''s face who succeeded in his revenge could only sigh as he prepared himself for a scolding session.

    While Julia was scolding Diehauser for his spartan attitude, Masaru was being dragged by another beautiful lady who wore a witch-like outfit. "Masaru, it''s time for your magic training" Her name was Circe, she was the other Bishop of his father''s team. Since it was a good excuse to escape from here he followed her to a more secluded area, Circe turned around looking at him "How has your magic progressed without the need of your Sacred Gear?"

    "It''s difficult, right now I am more familiar in molding and manipulating my Demonic energy because it uses images as a medium. But using magic based on calculations is a bit tough" Masaru thought about his magic training, because it was still early in his magic training this result already exceeded Circe''s expectations to which she remembered about this boy''s circumstances. "Well most people consider it simple... The human magicians magic which you are struggling with which uses calculation which is mostly only to understand if he do this and add this you will create this. In other words where Demonic Magic can skip the ''process'' that creates the ''Result'' spell, the human magic system requires them to also understand the process. For example you light a candle with a small flame, but what is fire? How does Fire start? Those questions are the process"

    Masaru nodded thinking that it was quite reasonable since the Humans did not have a cheat called Demonic Energy/Power, they would still search for things that can replace what they don''t have. "For today''s training we will focus on your demonic energy control, so make sure to study those books I gave you okay?" "Yes Circe oneesama" Masaru nodded before manipulating his demonic energy to flow towards his hands, soon several demonic bullets materialized floating above his hands.

    "Not bad, you can already use the Demon Bullet spell huh? Now then, try to change each of their nature to a element" Circe was intently looking at Masaru who was focusing his concentration on the bullets, five minutes went by and the first bullet''s attribute changed into Fire. Another 20 minutes pass by another bullet became water, soon three hours pass by when Masaru successfully converted the elements of his bullets to each element, Fire, water, earth, Wind, Lighting, Ice and finally his unique Attribute Worthless. The colour of the worthless bullet was similar to a regular demon bullet but those who had the Belial bloodline could feel their signature attribute pulsing actively in that bullet.

    "Now, while maintaining their attributes. Start with changing their shapes...." Circe began to instruct him further in magic, perhaps it was the influence of the sacred gear or the super devil constitution he had, the magic he learnt was difficult at first but the second time he started to manipulate and control the magic even easier with each passing turn. After another thirty minutes, Julia found Circe and Masaru but did not say a thing other than taking Masaru from Circe saying that she broke the rules in training him.

    "Geez Ma-Kun!!! Why did you learn something like that! Now I can''t teach you a lot!" Julia threw a tantrum but still felt proud at this boy who managed to come up with such a answer only after a week ever since they started their training.

    /

    It has been two years since Masaru came to the Belial Family, he was 10 years old today and because of the heated discussions he was elected as the Heir of Belial Family since his father stepped down because he simply wished to stay in the Rating Games. Masaru''s achievement in further his training in Senjutsu alongside Shirone under the tutelage of a Yokai, Swordsmanship under Okita Souji who was requested by Diehauser to each Masaru since he did not have anyone who could teach him as well as Okita could.

    But the thing that made Masaru known was his magic talent thanks to his Sacred Gear and the Teaching of all of two bishops of Diehauser''s team, Circe and Julia. Although he could not learn everything from the two ladies but he managed to record most of the spells into his sacred gear to continue his training. Because of his mindset of becoming strong in this world and stubborn nature he inherent from his father to never give up, the ladies of the peerage all treated Masaru preciously while the men all thought of him as a younger brother. Even the Werewolf Jacob Black who was Diehauser''s Rook felt even more comfortable that he was no longer the "Youngest one" and that was now passed onto Masaru.

    "Ma-kun, your collar is crooked" Julia, Diehauser''s bishop was responsible together with Circe to be the escort of Masaru for him to gain his evil pieces today. Masaru who heard her came towards her "Thank you Julia onee-sama" Julia who heard Masary smiled naturally as she felt even happier when Masaru call her elder sister, Circe who heard this felt jealous "I can fix it too!"

    before Circe could come close, Shirone jumped in front of Masaru thinking that Masaru might get harassed (Spoiled) by a women made her a bit jealous. "What''s wrong Shi-chan" Circe smiled at this little girl who became more active and lively under the ?ssaults of the ladies in the peerage who enjoyed doting on Masaru while teasing Shirone whom they noticed held special feelings towards Masaru who did not seem to notice it yet.

    When Shirone noticed nothing was wrong and that she was being teased at again could only pout before standing behind Masaru "Nothing" The two escort ladies could only giggle thinking she was cute, the four of them climbed into the carriage that led them towards the direction where Ajuka Beezlebub''s Research Facility was at to get his pieces.

    "Welcome, so you must be the new rising genius of the Belial Family huh? Nice to meet you Masaru Belial" a bewitchingly beautiful and attractive young man appearing in his early twenties, with light blue eyes and green hair that is slicked back personally came to receive the guests he expecting today which was Masaru and co. "It''s a honor to meet the Demon Lord Beezlebub" Masaru responded according to the etiquette required of him, and Ajuka simply waved "No need to formalities but just like Sirzech told me... Your Demonic Energy has increased again... Interesting"

    Masaru knew Ajuka was a researcher of a kind, whether it was the good or bad one he will never know but he did not feel any repulsive feelings towards him. "Apologies, you must be Julia and Circe the Bishops of Diehauser it has been a while" The two bishops curtsied ""It''s a honor to meet you Lord Beezlebub""

    In fact Masaru''s body could now be considered complete devil and was already showing signs of entering the power ranks of a High class devil both Psychically but Magic based he could already be considered Peak High class although he has the reserves of a Ultimate Class. "Although it might be stuffy to say this, but it is thanks to the experiments those fools done to your body that you gained quite a strong adaptable body full of potential... I believe you should explore your sacred gear a bit more as I have a feeling that it is not simply a medium to use magic only"

    "Thank you for your advice" Masaru was currently putting his clothes back, with the testing done they were led towards a Pedestal made out of a strange materials that were crimson/red coloured. "This is the Evil Piece System, simply touch the pedestal and you will be registered as a King and your pieces will be generated" Masaru nodded at his instructions and walked over to the pedestal, placing his hand.

    When the skin of his hand touched the slightly cold pedestal he felt a stronger heart beat echo within his body as his demonic power was undergoing a purifying process improving the quality while increasing his psychical base power in overall, when the process was over Ajuka came over to him handing over a rosewood box that held all of his evil pieces. Of all pieces only his Queen, one Rook, one Knight, one Bishop and five Pawns pieces were mutated while the rest were regular, "It''s quite amazing to see yet another set with several mutated pieces, your potential is surprisingly good"

    Masaru felt excited that he held his evil pieces in his hands but the first thing he had in his mind was Shirone, he turned around walking towards her. "Shirone, would you willing to become my Rook?" Shirone who heard Masaru asking her despite knowing her answer smiled warmly nodding, Masaru who confirmed her choice took out his regular Rook and held in front of her ?h?st allowing the rook piece to enter her body.

    Circe and Julia felt happy for Shirone who waited for two years for this day, they watched how Shirone''s body was giving of a faint crimson glow around her body for several minutes before the glow receded back into her body. "With this you are officially my Rook" Masaru announced it to Shirone who happily jumped into Masaru''s embrace "Now Onii-sama can''t escape nya"
