When Killua saw that Soren knew what it was, he didn't hesitate to choose the letter Y mentally. Once it was chosen Killua felt a tingling sensation inside of his body, and once it disappeared a display interface came up the read "Welcome Sub Host Killua" the message then disappeared and left him with a "guide" button. Once Killua pressed the button mentally it showed him the process of how to use the System, calling up his Stats, using the Inventory, buying from the Shop, spinning the Lottery, and taking Quests for items and System Points. After looking over the functions Killua asked some questions about the System with Soren.
[So, how long have you had this?... Does the one you own do anything different then the one you have given me?]: killua
[I have had this System I named Sakura for many years… As for what your system does, it does everything mine does, but it wont update to newer versions like mine, or let you teleport to new world's without my permission, so where I go, you go, and if any future functions like virtual training appear, mine will have it, but you're system won't]: soren
Killua was happy with what he has and decided to go get Gon from his training so that he could come here to get one as well. Killua handed Zeno back to Soren and disappeared, a few hours later Killua came back with Gon who was still confused, but decided to see what was going on. Soren then explained the whole story over again, and Gon was amazed at what was out there, after deciding to join Soren on his adventures, Soren gave him a System of his own, after looking through it he noticed something and shouted.
[Hey! You can customise the Color of the system]: gon
Soren was shocked while Killua shouted "Really!" and began to go through his own System changing the color. Soren never knew of this function as it was unnecessary, but Soren gave in and went into the settings to change his once plain White system into a new coloured one, after a moment Soren's new system's main color was Black, and was highlighted with a Teal glow, all the words and numbers were now Teal in color, a simple yet cool design. After Killua and Gon finished messing with their systems, Soren called both Misha and Hancock into the room for a private talk, Killua and Gon were allowed to stay, because they already know. Soren then gave Misha and Hancock a System, but before he gave the 2 babies their own System he stopped himself as they were only a couple months old, they wouldn't even be able to accept the notification.
[Alright!... Everyone should open their quest list and start completing quests to gain points… The more you collect the better stuff you can get from the store]: soren
When Killua and Gon heard this they opened up the Quest list like Soren said and saw the huge amount of quests that they could do easily, Killua then spoke to Gon in a childish voice like he used to.
[Hey Gon, wanna race to see who can complete more quests in a single day? Loser buys dinner for the Winner]: killua
[You read my mind… Your on! Prepare to buy me food Killua]: gon
Killua and Gon then darted out the house at blinding speeds, while Misha, Hancock and Soren just looked at each other and gave a chuckle. Misha then looked at her Quest Listings and found that most tasks should be a piece of cake for her, as when she looked at the Apex board she was 8th place, Hancock was 9th while Haku was 7th place. Both Misha and Hancock decided to go do some quests for a few hours while the babies sleep, they left Soren in the house to watch after Zenith and Zeno while they go collect points. While Soren was at home watching the boys, the city was in disarray as there were 2 blinding flashes shooting around before they finally disappeared, the 2 blinding flashes were Killua and Gon, they were doing small quests, like, Stop a bank robbery, stop an assault, or stop a corrupt government official, after they were done with those they moved on to the Dark Continent, there they fought beasts and monster's the size of cities. While this was going on Soren just bought a scouter to look at the babies power levels, they were strong and Soren could feel it, but he didn't know how strong, placing the scouter on his face he pressed the button and watched as it scanned their powers.
*Blip… Blip*
BP: 15,300 : Zenith
BP: 15,350 : Zeno
Soren was shocked to see such high battle power on his little babies. He then thought about if they were raised on a planet with increased gravity, how high would they grow as infant's, Soren then decided to remodel the house while the family were gone, Soren used a few thousand points to make the house a gravity chamber, he then raised the gravity to .5x as to not stress the babies. Seeing that .5x was nothing he raised it to 2x gravity and left it there, he then thought about their future growth and how strong they will become, Soren then sat in the empty house until evening came and the two women came through the door and were caught off guard by the pressure but it didn't affect them at all, they went to the living room to see Soren sleeping on the couch with Zeno and Zenith sleeping on top of him with their tails wrapped around his arm and leg respectively. Misha and Hancock then went to bed and let Soren sleep on the couch with the babies, later that night Killua and Gon came back exhausted to the point they could hardly stand, and once they entered the house they dropped to the floor because they were out of strength and 2x gravity was too much on their exhausted bodies, they then slept at the front door that night. For the next year Soren had taken it easy in the Hunter x Hunter world while killua and Gon did a bunch of quests that number in the thousands, they never took breaks unless they were eating, or sleeping, they made around 5 million system points each and had a few random bloodline spins, mostly their inventory was filled with Senzu Beans. Over the Year Killua and Gon asked about the name of the bloodline Soren had to give him a tail, and when they found out the name, they saved up for it, the bloodline cost 5 million system points and once they had enough they bought it and started the reconstruction of their bodies. Killua's hair color had changed unlike Soren's, Killua now had Dark Black hair that became more spiky than it was previously, his once compact muscles had bulked up and ripped through the suit he wore, then there was a furry Brown tail the sprouted from his backside. Gon mostly looked the same except he lost the Green highlights from his hair and a furry Brown tail sprouted from his backside, both Gon and Killua's eye color went from their previous Electric Blue, and Dark Green to a pure Black color.
[Congratulations you two! You are now a proud member of the Saiyan race… You guys will be ever growing in battle, the more you get hurt and heal the stronger you become from a thing called Zenkai boosts]: soren
Soren then heard some pitter patter coming from the other room and turned to see 2 boys running towards him while both shouting.
[[Papa!]]: zenith and zeno
Soren bent down to take the two kids into his arms while questioning them.
[Back so soon? Where are your mother's? I thought they took you guys to the city to pick out some clothes]: soren
[They are right behind us Papa! We ran in ahead when we got home]: zenith
Soren then heard the door open as two beautiful women came in and placed some bags onto the kitchen counter. Seeing Soren holding Zenith and Zeno they had a smile appear on there face, the walked up to Soren and each took a kiss while saying "we're back" Soren then gave each of them a slap on the ass which went unnoticed by everyone but the 2 who experienced Soren's slap. Soren then set both kids down and watched as they ran over to Killua and Gon while shouting.
[[Uncle Killua!... Uncle Gon! We missed you guys]]: zenith and zeno
Killua took Zenith into his arms while Gon took Zeno into his arms. The two enjoyed being uncle's to the two, Killua was the Blood Uncle while Gon was just a family friend, but Soren always looked at Gon as another brother, blood related or not. Soren then had the two kids go play in their rooms as Soren began to talk about the next world they would go to, and what they would need to do to blend in.
[I plan to raise Zenith and Zeno in a world that has no concept of Magic, Nen, or any kind of power that could destroy the world. Even though we are strong, I don't want to take the chance of them getting hurt by the aftermath of someone who may be fighting near them… The next world will have no such thing as Saiyan's, so we will either hid our tails, or cut them off, we can regrow them at a later time]: soren
[When do you plan to travel to this new world?]: killua
[Hmm… Let's see… The boys are 1 ½ years old, and you need to be 5 years old to start school... We will leave in 4 more years, this will give me enough time to teach you both Ki manipulation]: soren
[What's that?]: gon
Soren answered Gon by creating a sphere of Ki in his hand while saying.
[This is Ki manipulation… It is neither Nen nor Magic, but Life energy, and every living being has it just like Nen… Actually its a higher state of Nen as in you don't need to only focus on 1 category of Nen like Enhancing or Transmutation]: soren
Killua and Gon were excited to learn of something new and began to learn Ki Manipulation from Soren for the next 4 years, and 4 years later Soren gathered everyone and opened a World Portal while choosing the next destination.
'Next world, Soma Yukihira; Food Wars!': soren
They all entered and this time Soren didn't need to keep anyone in frozen space as they all had a System except for Zenith and Zeno, whose bodies were sturdy enough to survive in the void. Soren held both kids in his arms as they fell asleep, Killua and Gon were in awe along with Hancock, because this was their first time seeing this, Misha had seen this once before even though only a short time, so it was still awe inspiring but not so much. After a few hours of traveling a portal opened and the Sakura informed him to pick a timeline, soren looked at his boys then spoke.
'Travel to when Soma was just 4 ½ years old like my children': soren
They all entered the portal and came out on the other side, inside a dark alley. Soren was thankful that it wasn't some super populated area or it might have caused some trouble, Soren then looked towards everyone before he spoke to Gon and Killua.
[Okay! Either cut it off or hid it… I'm going to cut mine off for now… *Ouch*]: soren
Soren cut off his tail and looked towards the two sleeping children and towards their mothers who had faces that said "Don't you dare cut off their tails, or will will cut off your dragon" Soren shivered in thought of losing his Dragon, then he wrapped their tails around their waist and pulled their baggy pants over the tail covering it. Killua and Gon had sucked it up and cut their tails off while tossing them into their inventory like Soren did, they then left the alley and Soren searched for the closest Government office to go get ID for everyone, Soren walked in with his family and used his MS to secretly create their identities, Soren used a couple hundred thousand points in exchange for this world currency, they then left with their ID's and paperwork for the kids like their Birth certificate. Soren then took them to a bank to open up bank accounts, using his MS to make the teller not suspect where all this money had come from, Soren then handed each of them a debit card with around 300 million ¥, and from their they went to an open area in the mountains while Soren made sure nobody was around before he used his Ki to clear all the trees in a big space before he used Creation Magic from his Dragon Saiyan Bloodline to create a mansion, Soren then cleared a path down to the main road before coming back up to the mansion and entering.
[Soren… Couldn't you have used Creation Magic to forge documents?]: killua
[Yes and no… I could create documents, but they wouldn't be registered in the government's database… This house on the other hand will be registered under newly constructed and I will go turn in a form to have it considered as a formal address]: soren
Killua was surprised on how much thought Soren put into this plan. Killua then went to go pick a room while Soren, Misha and Hancock took Zenith and Zeno to go pick out a school, while Soren had Haku watch the house while they were gone. After researching and looking around for a bit, Soren found a nice school that was close to the house and in a good neighborhood, Soren, Misha and Hancock entered the school while holding Zenith and Zeno, they went to the main office to enroll the two almost 5 year olds.
[Can I help you guys? What are you looking for today?]: office lady
Soren stepped forward and spoke.
[I'd like to enroll my kids into this school please]: soren
The lady thought Soren was joking, because by looking at him, Soren didn't look a day over 19-20 he should have just gotten out of the school system, yet he is trying to enroll his "kids" but after Soren placed his ID in front of her that said he was 35 years old she almost spit out her coffee.
[And which one is your child?]: office lady
[Both… These are my 2 wives and 2 son's]: soren
The office lady then spit out her coffee, it covered her whole area, she then calmed down and started typing on a now sticky keyboard and asked questions.
[Name of the Parents?]: office lady
[Soren, Misha and Hancock Zoldyck]: soren
The lady typed them down and continued to ask questions.
[Name of children?]: office lady
[Zenith and Zeno Zoldyck]: soren
The lady then pulled up their files and saw that they were all set into the government's birth system. The office lady then printed out 2 forms for Soren to fill out and another 2 forms stating that the kids were now registered.
[With signing here you consent to your child learning here at ******** Pre School… Your child will starts schooling next week, there is a dress code that must be followed]: office lady
The lady handed Soren a dress code sheet, and he would need to go buy these clothes for Zeno and Zenith. Soren finished signing paperwork and left with Zeno, Zenith, Misha and Hancock in toe, from there Soren gave the list to Misha to have her go shopping with the kids and Hancock while he starts his next plan of action.
