Year 3721, the era of technology and AI, the era of peace between 3 realms ,afterlife, underworld and earth, it was just any other day in the lab, young lady typing bizarre stuff on the keyboard and letting out sigh after every attempt as it always ended in errors, but suddenly her expression was taken by surprise as her promt actually worked, she quickly rushed towards very strange machine with nervous expression and stared at it for a few seconds then out of the machine fell a body, human like , flesh and hair, difference could not be told from real human being, but it was all just hand made robot young lady now even more nervous took a chip from the same machine and inserted it into robots eye as she stared at it as if she was waiting for something to happen, and it did  the robot came to life and was not acting like any robot, it was very confused, looking around the room and observing stuff, the young lady now with happy and proud expression spoke out to the robot:-"Hey there little fella, how is it doing?"The robot with confused look on his face replied nervously- "H-Hello" - "Whoaaaa, you can talk?" Said the lady with proud expression- "I Guess so" Said the robot boy with whispering voice- "Can you move for me?" Said the lady with determination in her eyesThe Robot boy shook his hand around and said nervously:- "I guess so"- "Come on, stand up for me little boy" said the ladyThe robot boy tried to stand up but quickly trembled and fell on the ground as he whispered in shame:- "I can't"- "Awww, don't you worry little one, you will get used to it in no time" said the lady in comforting manner Suddenly a guy with lab coat walked in the room and waved at the lady:- "Hey Ayame, how is it going, i see you have made some progress on your work"- "You bet, he just came to life a few minutes ago, isn't he adorable? look at him, he is still learning how to walk" replied Ayame proudly- "Learn how to walk? but he is an AI, you can easily implant information in him and teach him how to walk in matter of seconds" Said the lab guy in confusion - "I don't want to make just an AI, i want to create an actual living creature with actual human feelings, so he has to go through normal human stuff and learning how to walk will be the first steps to that" said Ayame- "So you are over here creating hand made children because you can't have your own?" said lab guy while laughing- "Uugh, just shut up will you, its not that i can't, i simply choose not to" Replied Ayame as she rolled her eyes The guy in lab coat sat on the chair and ignited a cigar, Ayame sighed as she turned to him and said:- "Who even smokes nowadays, that was over a thousand years ago, and you forgot your employee ID again"Ayame walked out of the room and returned a few seconds later with Lab guy's employee ID and handed it over to him, As the lab guy took the ID three letters could be seen which said "Kyo", his name.- "You give those stupid things too much attention, everyone knows each other without those things you know" Said Kyo - "Will you ever say thanks without complaining?" Replied Ayame with annoyed expression - "Well, go back to your robot boy, lets see what he can do, i want to see too" Said Kyo with curious tone-"Oh right, Come on little boy, watch your mommy and learn how to walk" Said Ayame as she started walking around the room in funny way- "Oh so you are his mom now?" said Kyo while laughing-"UUUGH, SHUT UP WILL YOU" Replied Ayame now with very angry tone and attempted to hit him As Kyo attempted to dodge her punch he fell off his chair and started crawling around the room trying to run away from her while he yelled:- "EASY EASY, calm down i was just joking"As Ayame and Kyo were fighting suddenly the robot boy shut off as both of them looked at it confused:- "What happened to him?" said Ayame in sad voice- "This doesn't happen nowadays, its impossible that it ran out of power, they probably made a mistake while designing the model" Said Kyo as he stood up- "Well, his AI consciousness is still on that chip so i can give him new body"Suddenly The Robot boy booted up again and looked around confused as he stood up without any trouble this time , surprising both Kyo and Ayame, after standing up he spoke:- "Where the heck am i, how did i end up here"The robot boy didn't lose a single second, as soon as he caught glimpse of Ayame and Kyo he launched towards them and tried to punch them , Kyo managed to push himself and Ayame away from it at last second as he yelled: -"AYAME,YOUR ROBOT HAS LOST IT, WHAT DID YOU DO" -"What? Impossible , i didn't include any act of violence in his code" said Ayame in surprise- "We have to shut it off, pull out generator from his back, i will restrain him" Said Kyo in determined tone They Started running around the room, dodging many of the robots violent attacks, at last Kyo managed to get his hand on its head, pulling it down to the ground as he yelled: - "Now Ayame, shut him off"Ayame did as she was told to and removed the power generator from robot boys back as he was shut off, it took them a few seconds to calm down but once they did they stood up and stared down at the robot boy trying to figure out what happened, Kyo spoke first:- "Well, that was very weird, lets drag it in my lab and figure out what happened to it"- "That is a good idea, lets do that" said Ayame as both of them grabbed the robot and dragged it into Kyo's lab a few rooms- "Put it down on this table" Said Kyo as they both lifted and laid the robot on the tableAs the robot was laid down on the table, Kyo removed the chip from its eye and put it inside his machine, results came out immediately and left them puzzled as it did not even have any records of any violent actions let alone have it coded inside of it- "Well that is certainly weird" said Ayame- "hmm, maybe its not the chip but the robot body itself that is broken?" said Kyo- "That is very stupid, i brought this robot from highest rated company, there is no way it is broken" replied Ayame - "We can't know until we try" Said Kyo as he approached the robot and pried open its back as he dragged his weird microscope like machine and looked inside- "Well this is certainly weird, go grab me those goggles" said Kyo in surpriseAyame did as she was told and brought Kyo the goggles he wanted and gave them to him, as Kyo put on the goggles he gasped in surprise as he said slowly:- "What the fuck?"- "What, what is it?" said Ayame in impatient tone- "There is a soul inside this robot" Replied Kyo- "Whaaaat? poor soul probably got lost, lets identify it and send it back to afterlife" said Ayame in sad voice - "We should" but this is unusual, when was the last time that soul went around without angels attention, and how do we even identify it?" said Kyo- "We can ask Demon empress you know, her special eyes can identify any soul" Said Ayame- "Seriously? you know that i don't like her, we can just go straight to angels and let them take care of it you know" Replied Kyo with annoyed look- "No we can not, you know how prideful angels are, they wouldn't accept something so Unofficial and they would just make us look stupid" Said Ayame - "Ok, whatever, put that robot in a shrinkbox and lets go to demonic palace then" Said Kyo while rolling his eyesAyame immediately brought out a little cube from her pockets, put it on top of the robot and suddenly the cube expanded, turning into a big box which automatically wrapped around the robot boys body and shrank down into little cube once again, containing the robot inside as Ayame picked it up and headed to some weird platform with Kyo as AI voice spoke: - "Where would you like to go?"- "Demonic palace" Said Kyo, clearly annoyed from what he was doingA few seconds later the platform started glowing blue as Kyo and Ayame started turning into blue particles and were sent into sky, a few moments later the particles became whole again next to Demonic palace as Kyo and Ayame started walking towards the huge entrance of wooden gates as Kyo said:- "They never make this place modern, what is with this boring stone and wooden palace, we have so much technology nowadays"- "Yes but they prefer traditions over technology" Said Ayame in a nerdy tone As they kept walking the guards stopped them as they asked:- "Where are you going"- "We would like to see the empress" Said both Kyo and Ayame at the same time- "Any weapons on you?" Asked the guard as he started searching them, as he finished searching Kyo, the went on to search Ayame and found the cube in her pockets as he squinted his eyes and started inspecting it:- "This may be weapon, i can't let you carry that inside"- "But, that is what we came here for, you have to let us, why would we want to harm the empress"As the complaining continued, the empress came out of the doors, looking all royal with her huge black spiky armor and very long white hair and pale white skin, her eyes light red color as she ordered to the guards:- "Let them in, they are friends"The guard nodded in approval as he returned the cube to Ayame and opened the gate wider for them as they started walking inside, as they got in the gates closed and they all sat on the chairs nearby, the empress asked: - "So, what brings you here today my dear friends"- "Hey Lilith, we've had trouble with souls and we knew that you were just one for the job" said Ayame in excited tone - "So, Ayame over here somehow trapped a soul inside her robot and now we are trying to figure out its identity" Said Kyo - "HEY, its not my fault, i don't know how the soul ended up in there" Said Ayame as she pouted and looked away from Kyo- "I see what happened over here, i can do that for you" Said Lilith while smiling- "Alrighty, lets do this" Said Ayame with determined face as she pulled out the cube from her pockets and placed it on the table, she pressed the button on the cube as it expanded once again, revealing the robot that was inside of it, Kyo once again pried open the back of the robot and revealed the place where soul would be and pointed at it as he said:- "Over here, take a look"- "Let's see" Said Lilith as she stared down the soul - "So, what do you see?" Asked Ayame- "Huh? this is weird, i have never seen a soul like this, it's very ancient" said Lilith with surprise - "Well, try identifying its name" Replied Kyo Lilith nodded and activated her demonic eyes as she yelled "Soul vision", as her eyes started shining and glowing she stared down to the soul, after careful inspection she said: - "I can not identify it's last name but i will try to see first name, i think it's a male" As she proceeded to put more and more energy in her eyes Lilith suddenly started sweating as her expression started turning more and more nervous and later scared as finally she fell back, immediately deactivating her eyes in fear as she was barley speaking:- "Where in the world did you find this soul"- "What happened" Yelled out Ayame in concerned look - "This soul is something else, i will tell you about it" Said Lilith in still frightened face -"We are all ears" said Kyo with curious look followed with Ayame's nod of agreement Lilith still trembling from fear stood up and sat on her throne as she took a deep breath and got ready to tell the story- "As you are aware, We have 3 Realms nowadays, Afterlife , Earth and Underworld and each realms have their respective Gods, We ourselves have never seen those gods but we have a lot of proof that they exist, they often give us signs too, but a few billion years ago there used to be 7 Gods , to this day it's still unknown what realm they ruled or what they were called but we know they existed, it also happened to be the same era where human whose soul you have brought here was alive, while its true that i call him human, he was more evil than any Demon or creature in history, a little is known about him but we know that he was just unhinged murderer that was going around conquering not only countries and continents all by himself but realms too, we don't know what he really looked like, there are many different stories and myths, some describe him to be over 3 meter giant with 6 arms, huge claws and fire instead of hair, some describe him with just a shadow that has powers to convert into any shape and size, those are of course just myths, we have no idea of his appearance or powers but one thing all myths and legends tell us is that everywhere he went he caused chaos and destruction, one day he went to underworld and started slaughtering powerful demons one after another, it was first and last time in history when the gods had to get involved, all 7 of the gods teamed up and started fighting him, he managed to kill 4 of them but in the end he was outnumbered, he was defeated and killed but his soul was too powerful even for the remaining 3 gods to destroy so they just sent it at the edge of the universe, far away from any of the realms and imprisoned him there, From those stories only information about him that we are certainly aware of is his name, which is "Sadan" that is the only thing gods told us according to ancient books and then they disappeared once again"- "Whoa, i was not expecting that but, even so , how did soul so powerful end up in our robot?" Asked Kyo curiously- "Electricity has some kind of attraction effect towards souls, he probably escaped from the prison long time ago and was making his way back all this time over here, depending that it only took him a few billion years, he must be moving at insane speed because universe is huge, once he ended up here, he got sucked in highest electricity outputting robot, that just happened to be yours" Replied Lilith- "Ok but what should we do about it now, we have some ancient murderer in our robot and we have no idea how to get rid of it" Said Kyo- "Remember when it attacked us? it was probably the soul in control and not my AI" Said Ayame - "Nowadays humans have not even a single drop of soul current but back in the days when Sadan was still around pretty much any human could use it but Sadan Was master at it, we are not aware what his technique was but as long as he is in that robotic body, he can not use it, if we do not let him posses an actual body and keep him imprisoned in that robotic body, we should be fine" Replied Lilith in slightly calmer tone - "What is a soul current?" Asked Ayame curiously- "It's basically a spiritual energy that allowed humans to do magical stuff, as we evolved we slowly lost it but angels and demons still have it" Replied Kyo in proud tone as he received nod of approval from Lilith While they were distracted in their conversation the robot awoke and used its jetpack to dash out of the palace window as he left everyone in surprise- "AYAMEEE WHAT THE FUCK IS THAT? WHY WOULD YOU GIVE IT A JETPACK AND WHY DID YOU EVEN PUT HIS GENERATOR BACK INTO HIM?" yelled Kyo in angry tone - "Well, i wanted him to have some fun you know and i put the generator back because i thought Lilith might need it to inspect the soul?" Replied Ayame in guilty face- "OK WHATEVER, PULL OUT YOUR PHONE AND LETS TRACK IT" Yelled Kyo - "Uuuuh, about that, i didn't put a tracking device on him" Replied Ayame with even guiltier voice - "YOU WHAT" Replied Kyo clearly mad now- "I wanted my child to have more freedom" said Ayame with sad voice - "Uugh, i swear ,if we somehow survive ancient prehistoric psycho murderer trying to eradicate us you will go and have an actual children, no more robots" Said Kyo while rolling his eyes- "Enough arguing guys, i think i know what he is up to and if he manages to achieve it we are practically doomed, we must stop him" Said Lilith as she started running outside and following jetpack traces Ayame and Kyo also followed Lilith as she started explaining on the way:- "This is mentioned in the ancient books, it's said that when Sadan was murdered his last words were that he would come back and revert existence, i think he is trying to go back in time where he was still alive and posses his original body to regain his full strength"- "But time travel is impossible, it has been confirmed many times over the centuries, how does he plan going to the past?" Said Kyo- "Impossible with technology, and our magic, ancient soul current might just be able to achieve it" Replied Lilith A few minutes of running later they stopped at a cemetery as they found the robot dropped over there, Lilith quickly went in to check for the soul but she shook her head as she said in disappointment:- "Its too late, it has left this robot body, look at that grave, its dug out, seems like he possessed an actual human body , but i can sense his soul trail, decomposed body is very flawed and leaves a lot of trial ,lets follow it" They kept running and running as they finally ended up in a dark cave, with weird smell, as they they kept running, they finally caught up with Sadan as he was performing some sort of ritual next to river that was somehow red, as Kyo, Lilith and Ayame arrived, it was already too late as the ritual was already progressing without Sadan getting involved, as they stood there in shock and surprise Sadan gave them evil grin as he spread his arms and yelled out: - "YOU GUYS ARE TOO LATE, THIS IS THE BEGGINING OF THE APOCALYPSE" As he finished his words the light got brighter and brighter, finally exploding and blinding Lilith, Kyo and Ayame, as they finally opened up their eyes they were left with completely different sight from what they were looking at a few moments ago, They were standing on a mountain, looking down on the world, Day had turned into night and all they could see was rubble of some castle remains and dead bodies as their shock and surprise finally gave them opportunity to speak, Lilith spoke first:- "I-i think w-we are in the past"
