While Anos was travelling in the void, returning, In Ophis's Mansion, three little girls were there, the girls were Sona Voldigoad, Tsubaki Shinra and Rias Gremory.
Sona is regularly coming in the mansion, since Anos left as she missed him, while she also travelled to the human world, several times with her sister, and during that time, she found Tsubaki Shinra,
Tsubaki was born in the Shinra Clan which has an ancient and honorable origin that purifies evil spirits, but due to her trait that calls out to abnormal beings through her mirrors, she received a state which was basically isolation from the other members. She eventually overcame that by becoming a Devil under Sona and changed the mirror to her own powers, which became her Sacred Gear; Mirror Alice.
After becoming Sona's queen, she developed her powers but not much time had passed as it's been six months since they met and the pieces are not from Ajuka but Anos had left her that as he wouldn't want her to use those low quality while having the bloodline of Demon king of Tyranny, and her pieces are similar to Grayfia, but her piece make the person her servant partially, which means that if her Order is inappropriate or harmful towards the servant, they could break free from that order. Anos actually doesn't want to make the servant pieces but he remembered that there are many stray devil's and the same could also happen with Sona so he had make those pieces.
After becoming Sona's queen, Tsubaki's bloodline is slowly changing towards a devil but what type it's going to be is not confirmed as it's developing according to her power.
Before Meeting Tsubaki, Sona became friends with Rias, when she had gone to Gremory Territory with her Sister, at first she doesn't like her attitude of being the spoiled Princess but got used to it and she had developed interest in the Chess game because she wanted to beat Ophis in it, as she always wanted to sit on Anos's lap, but no one other then Anos is allowed, so she thought of beating Ophis and taking that position but she can't beat Ophis in Strength so she decided to do that in different thing and at that time she found Chess interesting, so she decided to beat Ophis in it, but everytime she got defeated, so she trained in Chess and Rias became her perfect partner for that.
Meanwhile Rias is happy to became Sona's friend because nobody was willing to be her friend as the Daughter of one of the 72 pillar house and as the sister of the Maou, everyone just wants to be her friend to have connection with that and she was already having a hard time due to the fact that her family already decide a partner for her in marriage, but then she met Sona, and became her friend as she was curious as she had heard from her brother about Sona as how she is the most talented devil of younger generation.
Today, they are at Ophis's Mansion because they wanted to play the games that Anos had, which he make his ownself, and Sona was always winning, Rias looked at Sona and said,
Rias-"Sona-chan, Why are we playing here again?"
Sona looked at Rias and shrugged her shoulders and said,
Sona-"Because if I am in any other place, Onee-sama is going to come, but she can't come here, as she doesn't have the key and permission to enter the house."
Rias looked at her and said,
Rias-"Why are you always running from Serafall-sama?"
Sona-"Because she started to wear that weird dress and she also forces me to wear that, and I don't want that, as she is going to take pictures and show it to Anos-Onii-san, which is the last thing I want to happen."
Hearing that Tsubaki who was standing behind Sona smiled, as she had seen it herself and Serafall was even forcing her to wear that, but she somehow manage to escape from that but Sona was having a hard time, as Serafall had placed many protection charms and magics on her and Tsubaki along with some tracking spells, because of which, they had a hard time.
Rias then looked at her friend suspiciously, as she had heard about the Great Anos-sama, from Sona many times and whenever she asked her brother, he would say that she is still a child, so she had a hard time believing that Anos is really that great, and Sona herself could see that as it's written on Rias face.
Tsubaki who was behind Sona looked at her and spoke,
Tsubaki-"I am also excited to meet Anos-sama, and according to what you had told, He should be coming in a week or so as a year has already passed."
Hearing that Sona smiled as she herself was excited to meet Anos after all this time.
Meanwhile, Rias looked weird as Sona never smiled except when she is with her family or with Rias or talking about Anos, so she thought of it as weird.
While they were talking, a portal appeared in the room, seeing that portal, both Rias and Tsubaki put on a defensive posture, while Sona looked at the portal attentively, and soon Anos and his group came from the portal, upon existing from the portal, everyone from 'TDG' universe looked around and soon locked their eyes on the three girls but they first closed their eyes as they sensed the energy in the environment here, and found it more than from the array Ophis had made.
While Rias and Tsubaki was looking at them cautiously, Anos move towards Sona and patted her head and said,
Anos-"Good day to you, Sona-chan."
Ophis also started patting Sona, while Sona attentively looked at the girls who came with Anos and then towards Anos and spoke,
Sona-"Greetings, Anos-Onii-san, Ophis-sama, and Grayfia-sama."
She had always called Ophis like that, especially seeing her always sitting on Anos's lap, it became even more difficult for her to call Onee-san, so she calls her with -sama.
Meanwhile, Grayfia spoke,
Grayfia-"Greetings, Sona-sama, Rias-sama and Tsubaki-sama."
Grayfia had read the 'Highschool DxD' so she knows about them somewhat, while both Rias and Tsubaki were surprised that Grayfia knows them but even more so that the man that had came right now is Anos.
While Sona looked at Anos and spoke,
Sona-"Onii-san, were you going to another world to have more Harem?"
Hearing that Ye Ziyun and Xiao Ning'er blushed, while Yu Yan and Ying Yueru looked the same as they are already past the feeling of shame, especially from a child's mouth.
While Ophis who was beside Anos suddenly opened her eyes wide and spoke,
Ophis-"Ohh! Right, it really looks like you are going to have more harem members."
Anos looked at weirdly hearing that and Ophis turned her head as she wanted to make a joke but it doesn't came right, Anos then turned towards Sona and said,
Anos-"And what do you think?"
Sona then thought for a while and shook her head,
Sona-"Well, I don't think so, as for you to fall in love with another person is difficult if you hadn't spend a very large amount of time with them."
Hearing that Anos and Grayfia nodded their head and Anos spoke,
Anos-"Yep, you are right, after all, time had no affect onto, and the same is for you, and it is the last thing that I lack, so I never am worried about that, and as for me falling is also going to take a very long time."
Sona nodded her hearing that and then turned behind and then spoke,
Sona-"Oh Right, Onii-san, meet Tsubaki Shinra, my Queen and Beside her is Rias Gremory, my friend and she is the little sister of the Maou Sirzechs."
Hearing that Anos first looked at Tsubaki and then at Sona and spoke,
Anos-"She is definitely going to give you a surprise in the future."
Anos then turned towards Rias and spoke,
Anos-"You are that Sirzechs sister, I guess like Brother like Sister."
Hearing that, Rias became angry as for her, her brother is her pride and was about to lash out but Grayfia just looked at her and she stood there, and then looked around, while it may seem bad doing that to a child, but that is only for normal child, while Devils brain develop fast as it could be seen how easily Sona was talking with Anos which is difficult for a child.
Sona looked at Anos with a questioning look but don't became angry as this was the last thing she would do and asked,
Sona-"What do you mean by that, Onii-san"
Anos looked at her and said,
Anos-"Their Pride."
Hearing that Sona nodded her head as she knew that Sirzechs and Rias are way too proudful of their Power of Destruction, which now even she could easily use.
But Rias who heard that felt even more anger and Anos spoke,
Anos-"Then lets introduce from our side."
Hearing that, the four who were behind him began introducing themselves and after that, all of them sat down and Anos spoke while looking at Sona,
Anos-"You should make your schedule for the next month free, as I am taking Ophis on a date for a week, and the world I am going had very good food, and you could even ask Sera if she wants to come."
Hearing that Sona spoke,
Sona-"But aren't we going to be a problem, during your date?"
Anos shook his head hearing that and said,
Anos-"You are going to stay in that world and travel yourself or within the group, not with me and Ophis."
Sona nodded her head hearing as she really doesn't want to be with them during their date, and Xiao Ning'er, who was beside the other three spoke,
Xiao Ning'er-"Are we also coming with you?"
Hearing her, other three also looked at Anos, Anos seeing that nodded his head and said,
Anos-"Yes, that's why I said, one week, so you could get used to this world as that world is similar to this world, but more normal."
Hearing that, all four of them nodded their head, as they really want to get used to this world first, then travel to other.
Anos then looked at everyone and turned towards Grayfia and spoke,
Anos-"Grayfia, Call the Four Maou's and Zekram here, I want to have a talk with them."
Hearing that Grayfia nodded her head and five small magic circles appeared on her ears and she spoke,
Grayfia-"Anos-sama required your presence in the Mansion, Teleportation is allowed."
After that, the magic circles disappeared and a few minutes later, Five magic circles appeared and the four Maou's appeared along with Zekram and looked at Anos and bowed their head while Serafall looked at Anos with a pout and spoke,
Serafall-"Anos-chan, can't you take me with you, when you had gone??"
Anos looked at her and smiled but when he looked at her clothes, he spoke,
Anos-"Sera, Why are you wearing a Magical Girl Dress? Were you doing cosplay or something?"
Serafall shook her head and spoke while taking the staff from her waist and wave it around,
Serafall-"I am the Magical Girl Levi-tan!!"
Hearing that Anos shook his head and said,
Anos-"Well I am not gonna comment about that, but I guess you look good in that?"
Hearing that Serafall nodded her head and asked Anos,
Serafall-"So, how was your trip,(Looking at Yu Yan, Ye Ziyun, Xiao Ning'er and Ying Yueru) looking at it like that, it looks like you were travelling to have more harem members."
Hearing that Anos shook his head as he knew that Serafall was joking but Yu Yan shot Serafall a glare as she spoke,
Yu Yan-"What do you mean by saying it like we doesn't even exist here?"
Yu Yan spoke in a very cold voice, but the temperature around the room started to became high and three Maou's and Zekram were surprised, as they don't feel a single thing from the four of them and Serafall felt herself in burning over and over again as the temperature around her was the highest.
Yu Yan had done that because it was very rude way of calling them, as she had no problem with becoming Anos's women, but she wasn't and the way Serafall was calling them felt like Anos was collecting women's and she and others are a part of that, she had ignored Sona before as she is a child, but Serafall is not a child.
While Ophis also looked at Serafall with a blank gaze, as she herself knew that Serafall was joking, but that was really rude way of calling them and Serafall was sweating hard, and Sona was about to intervene but Ophis stop her and said in a low voice which only Sona could hear,
Ophis-"Calm down, she is not going to kill your sister, and this could be a lesson for your sister as her behaviour was becoming more problematic and you knew, she was becoming too cheerful with everyone and was talking in rude ways too many times."
Hearing that Sona nodded her head as she knew that Serafall's behaviour was becoming a problem, while she had done her work in a good way and always helped others, but her talking ways was becoming rude, and she herself was acting inappropriate in many ways, but she still looked at her sister worriedly.
While Anos looked at Serafall and spoke in a cold voice,
Anos-"Serafall, you should know that what you had said just now was extremely rude, when you don't know about other party, and whether they are my harem or not is of no problem for you, remember that, and this type of thing shouldn't happen again."
Hearing that, Serafall quickly nodded her head but felt cold all over her body, hearing Anos talking to her like that and his eyes were cold looking at her.
While Anos looked at Yu Yan and indicate her to remove the pressure, and she did that, but not before shooting a glare at Serafall.
After the pressure was removed, the temperature started to became normal and Serafall fell on the floor and gasped for breath that she was holding all the time, while looking at Yu Yan fearfully, and she knew that if Anos hadn't helped her, then she would have died. While, Sona and Tsubaki went towards her to help her and Anos turned towards others and spoke,
Anos-"Sit down, I have called you here to make an announcement."
Hearing that all of them sat down and Serafall also sat down with them, but this time her head was hung down and Anos looked at Ajuka and spoke,
Anos-"Congratulations, for becoming the REAL Maou."
Hearing that, Sirzechs looked at Ajuka with a shocked face and also felt anger towards himself for not becoming a real Maou and Ajuka looked at Anos and smiled humbly and spoke,
Ajuka-"Its due to your advise, that I could became one."
Hearing that, Anos shook his head and said,
Anos-"Ajuka, you could have became one, even without my help."
After saying that Anos looked at everyone and spoke,
Anos-"I had called you here because, The four who had come with me are going to live here and they are going to travel, so if a problem occurred or someone offended them, then they could kill that person if the reason is valid and I am telling you this, so you could make the preparations on your side."
After that Yu Yan, Ying Yueru, Ye Ziyun and Xiao Ning'er introduce themselves and the four Maou's already started making plans in their head and Anos then said,
Anos-"If you want to stay now, you could, but I have some work to do in the backyard, or you could also watch."
They then nodded their head and decided to watch Anos and Anos turned towards Yu Yan and said,
Anos-"Yu Yan, could you come with me as I think it should be possible for you to become a Real Law God in this world, and I am going to call the World Will for that."
Hearing that, Yu Yan nodded her head as she is also somewhat excited as she had heard about the basic structure of DxD World from Grayfia, so she knows what a god is and she knew that she could become more strong by becoming one.
Yu Yan followed Anos to the Backyard while everyone also followed behind them.
After reaching there, Anos removed a part of the barrier on the Mansion and called the World Will, after a minute, light particles started to gather and form a beautiful girl's figure.
