The light of the screen poorly illuminated the generally dark room where Doctor Ishikawa Youji, the specialist in nuclear physics, quantum theory, and the general programmer, works. As he is about to press compile on a code, he is receiving a call.

"Yes? It's Ishikawa." Doctor says as he listens to a calm feminine voice.

"Hi. It's Sakura. We had a little problem with some research. Can you come in person to section 3?" Sakura asked as she was hoping she would understand the data that was presented to her if the best of the best in this scientific facility will come in.

"Fine, give me a few minutes," Ishikawa said as he sighed and hung up. He clicked compile and let the huge pile of code is worked out by the powerful machine that he was given. He worked for seven years in this advanced AI-augmented research facility in downtown Tokyo that got its nuclear reactor. The doctor closed the room and enabled the alarm. To ensure it is closed, the doctor moves the door handle to see if it opens. Hard. No, it did not. Ensuring he did it right, he closed the door on the key that he always has on his neck and headed out.

"Sup Youji!" Said a young guy in his 20s, who as the nameplate suggests, was Doctor Kurosawa. "Something wrong?" His energetic tone changed as he noticed Youji's bad mood.

"Nah. Just section three has problems. As always." Youji said as he let out a sigh of breath when he walked to the big 4 meters wide elevator doors in the largely sterile hallway. Like everything here.

"I see. Just lemme know, sir, if you need any help." Kurosawa said as Youji nodded.

"Will keep that in mind, kid," Youji said as he sighed, and went to the elevator, boarded it, and pressed a level 3 button, to get fastest to the wing.

'These damn rookies, are soo inexperienced in that work.' Youji thinks in his mind as he can't stand the workload anymore. He is a scientist. Yes. But he is also a 50-year-old man. Despite his fine physiques, like lightly-muscled chest and other signs of good physical health, the man's hair… Is gray. Slowly starts to fall off.

'I wish I could get a vacation.' He thinks in his mind as the elevator stops at level 8. 'Here. Let's make Sakura's request quickly, so I can get back to my AI research.'

Ishikawa sighs as he gets out of the elevator as it opens, surprising many of the scientists on this level, but they quickly shrug it off. He then turns right and moves past a few doors. Same iron doors, with safety and security in mind. He knocks to one of them, making loud noises in the room as Sakura, bored, masturbates. Hearing this, she quickly jumps out from the chair and goes to the room, not expecting the doctor to be this quick in this section of the lab.. She still forgot to clean up her hands from all the… Moisture she had on her hand.

When she opened the door for the doc, she smiled, as he noticed the small detail.

"Eh… Masturbating at work again, Doctor Suzuki?" Asked Youji as he looked at her hand as she quickly went to the sink and cleaned up her hands.

"No no no, not at all! I am in fact quite successful with fighting my addiction!" Sakura obviously lied as he put his hands under his chest, disappointed in his protege.

"I do not believe it, sweetheart. Anyway, What was the problem?"

"Oh yes yes." Sakura nodded as she went instantly to her machine and put forth the data analysis paper she made. "Have a look at this."

She opened a PDF file as he had a look and read the data.

"The data implies that we managed to discover several… Weird particles.. But when I run it again… It's fucking bonkers!" Sakura yelled out as she showed the data and scrolled down a few pages. "40% of the research tests we did over a week and with heavy sorting done by the AI to detect scan data mishaps… It is still coming out largely the same."

Youji smirked as he looked at the papers. Then, he smiled. The smile grew to the limits as he started to laugh. His laugh became louder. "YES! THANK GOD! WE HAVE IT, SAKURA! WE HAVE IT!"

"Huh?" Sakura looks at him as she blinks twice. "What do we have?"

"We just observed negative matter!" Youji yells out as he jumps on her, hugs and lifts her up, with the joy of a child on his face, and puts her down as he starts to dance. "One step closer to the warp drive! Yahoo!"

"Damn, I never understand you sometimes," Sakura said as she put her hands under her chest as she looked at the computer screen. "But if it is as you say.. Can we get approval to rerun the tests?"

"Yes yes, do it please," Youji said as he calmed himself down. "I can't wait for the director board meeting! This means more funding!"

"Lemme know how good it went!" Sakura said as she went back to work and Youji went out of the lab room, waving his hands off, but reminded her of something just in case.

"Do a backup of that data on a private server just in case, outside of the site," Youji said as he went out and headed to the elevator, where he pressed a button for floor 3.

As he descended, he noticed what kind of hour it was, as the elevator descended on the third floor three, opening the door. Youji turned right and went back to his room, which was basically a single-person apartment at this point. Yes, he was so dedicated to his job, he was willing to live in his workplace. When others saved up and bought homes, he simply used the facility for that.

As he looked around, he opened the doors with the keys, pulled out an identification card to open the doors, and then went through the doors, closing them behind him using a traditional lock, so no electronic one will work. He put down his lab coat, his shirt, took off his shoes, and went to the small room near the entrance. It's a bathroom, equipped with a toilet that shares space with a big fully functional shower cabin.

As he is taking shower, his fears and troubles, as well stress gets washed out, as he takes deep breaths, washes his hair, and uses silver-mixed shower soap to clean himself properly. After finishing, he gets out and cleans himself, going out naked from the cabin, and then putting on a pajama, going to sleep.

In the next 8 hours, it is not really a thing. Just a regular sleep, until he wakes up suddenly, with a loud noise describable as a mix of air bombing siren and containment breach alarm. Surprisingly when he dresses up, packs up his laptop into a bag, pulls out his hard drive to save important data, which takes a few minutes, opens the doors and then he notices that there is nobody around as the alarm is still off.

'Could it be a nuclear plant?' He asks himself. Last decade ago in this research station, an accident happened during a safety test so he expected that. But no. As he kept walking the hallway, he now noticed plenty of blast doors around the room. As they start to close down, he rushes to the exit but the second he gets there it's closed. Then a few behind him open to reveal a hooded figure that's 230 centimeters in height.

The figure telepathically lifted the man up as he revealed his face to be a bird's face. Specifically, a pigeon's face with bull horns on its head turned backward. Its eyes glowed dark as he lifted him and pushed to the doors, as the facility started to burn.

"Trust the divine. They might be your only saviors, Youji Ishikawa." He said with a dark, creepy tone, somewhat distorted as he pulled him to himself, kissed him if you can call it that, with its beak, and threw him through the doors, making him fall, when the research facility was getting blown up. He woke up with a scream and fear on his face.

"Shit! AAAAAAAA! NO!" Youji woke up with fear as he was sweaty, and felt hot. Usual reaction for a man who just got woken up.

'Nightmares… What bothers me?' He asks as he tries rationally to explain this weird, supernatural encounter. 'Was it really, though…' He noticed the small window in the room open wide enough for a door to be opened when he noticed a pigeon looking and stabbing the window, thinking it got something.

"Shoo, shoo. Bad bird!" Youji yelled out as he successfully got the bird away, but something made him nervous. He instantly went to his computer as he saw the results of the code compiled and tested by his General Purpose Neural Intelligence 'ARIN' that stands for Artificial Intelligence. ' ARIN. You seem to do your job well.'

"Something bothers you, Youji? I detected a high amount of cortisol and other.. Sweet Gods! Dude." A feminine voice goes out from the speakers as two mirrors project a hard-light figure of a beautiful woman in her 40s, with big jugs, wide hips, big enough ass to make any man go after her. Dressed in a black tube top and a skirt. She put her holographic hand on his head to check him on. "Dude… Go to the doc."

"Hey. Arin. You rarely wake up for interaction on your own.." He noticed.

"What happened?" Arin asks as she looks at his scarred face.

"I had… A nightmare." He replied. There is no point in fighting a self-aware AI that got access to your biological reading.

"Nightmare, huh?" Arin asks.

"Yea. The big bird-headed figure pushed me out of this facility when it was about to blow up." He takes a deep breath. "He said.. Trust only in the divine that they can save you or something. Just some superstitious shit." He said.

"You know. You made me. But what made your species, Youji? Something definitely intervened here. On a genetic level. This mutation made your species yours. Is just too perfect." Arin said as she presented him the project data.

"I know about that. But these might be aliens as well. If you want to talk about that." Youji said as Arin chuckled.

"You know. When a sentient AI considers the existence of the divine higher being and a human denies its existence… Know something happens, sweetie." Arin said as she made him think about what she said. Her voice? It could be described as sweet and caring. Low pitched, to add a feeling of a flirty adult. It was his idea to make her more. Liveable in the early stage of development. He is pleased her sentience is not causing problems like Terminator. Yet.

"I know. Anyway, prep the backup on my DNA Drive. I have bad feelings about something." Youji said as he walked to the storage rack that stored plenty of HDD and pulled it back into the room as he, still in his clothes, opened his laptop.

"Ummm… Okay? But Youji… Buddy. Why so nervous?" Arin asks as she looks at him.

"I got a bad feeling about this whole shit, okay? Better make a backup. So our discovery of Negative Matter is not going to waste." Youji said as he sighed, looking at the rigged device, and initiated a backup procedure which informed all the researchers on the base about it. This upset people who were about to make research on the negative matter go further.

"Oh come on!" Sakura said as she noticed the app window.

"Please be informed. All research personnel is to recommend ceasing all research for the time of creating a backup. Downtime, 5 minutes." A robotic voice said as Sakura sighed.

"Old man, you dummy… What are you doing now!?" Sakura asked as she got up, with her hand wet as she went to a sink and cleaned it up so the old man wouldn't notice her habits taking over.

As the dude began the procedure, he dressed up. It took five minutes.

"That's… Weird." Arin said as she opened a general-purpose interactive box for herself, making a projection of it. "Hmm… The Tokamak one is… Fine. Two is fine, three is fine… Four… O shit."

"What happened, Arin?" Youji asks as he looks at her.

"Well.. The technicians are repairing it but… It looks so messed up.. These data are off the charts… O, Sweet Jesus." Arin said as she got shocked and Youji looked at the number. He was scared too.

"Arin?" He asks as he comes to her, dressed as he pinned out the DNA Drive that had 800 terabytes of data on it.

"Well, shit is going down. I guess your nightmare was you warning yourself from the tokamak… Damn, that is too unstable and when it will go off.." Arin said as she opened her holographic eyes widely. "Youji, evacuation procedure. And put me out." Arin said as Youji noted when they heard a knock.

"Youji, old bastard why making backup now!?" Sakura asks as she knocks on the iron door when Youji shut down the protector and pull out a cartridge that looked like a flashcard but in reality, was a DNA-based device that could store Zettabyte of data.

"Damnit." He says as she makes the AI chuckle for a while. Youji goes to the door and opens it, hard.

"What? Tokamak number 4 is unstable." Youji said as he put the big drive and the AI chip into the case he pulled out from the bed.

"What?! This will…" Sakura looked panicked as she turned her head around. "We have to evacuate!"

"Too late, Sakura. I will initiate the evac procedure. But.." Youji said as he lifted up a protective case from the button on the wall that was near his doors and hit it hard, launching off the siren alarm with a hum alarm that was inside the entire facility.

"Warning, Tokamak number 4 is unstable. Emergency Evac procedures activated. Please stop all the research and go to the evacuation point."

A robotic voice spoke as the two went to the exit.

"Jesus, Youji," Sakura said as she walked with him, noticing his nervousness. "The research is going to cause trouble here, you know that?"

"I do," Ishikawa said as he walked to the door, and when he pushed the doorknob, the explosion wave from releasing the negative mass too quickly occurred which instantly blew up all three stable tokamaks and threw them both into the air. Suddenly time started to slow down as it stopped, with Youji maintaining some forms of consciousness through that moment, and with Sakura's eyes showing signs of none.

"Oh shit, what the hell?" Youji asks as he looks around. "What the fuck is going on!? I should be dead by now!" Youji yells out as he notices a serpent showing up as he burns with flame resembling that coming from a modern gas oven but the blue fire was definitely covered by the excessive red color so it took a moment to notice it. The serpent turned around and bit its own tail, lighting up the skin of his with green light, showing up the Slavic runes on it, creating a portal. As the portal appeared, Youji was definitely scared.

"Sweet Jesus," Youji said as he noticed the figure coming out. It was a humanoid yes. Unhooded, that revealed interesting looks. A human form is covered by a piece of silk put in a shape resembling that of a Roman senator. 'What are you? Some Roman deity? No no, I haven't heard from you... Celt?' He asks as he remembers the moment when Arin mentioned higher beings stuff briefly.

The upper torso side, though, resembles that of a wolf, covered with fur. Both hands are the ones with a paw. He is also equipped with a staff resembling that of nobility from the time of the renaissance.

His most disturbing detail though is a detail that he did not skip. The second head is that of a bull, the third one is that of a sheep. The wolf's head got bull's horns, the sheep had wolf's ears and the bull had the sheep's ears.

"Who are you!?" Youji asked as he looked at the man. Or something...

"My name is Veles. Damn, I just managed to get here in time. Good." Veles said as he looked at the devastation the negative mass explosion caused. "Look I do not have much time in this world… Yes, I am the Slavic God of Death by the way."

"Jesus. Slavs were right the whole damn time!" Youji said as he looked at Veles's head.

"They were but your gods… Are many. Think why there are many religions? Because they compete for power and influence over the souls of mortals. Slavic faith is the only one that does not depend on stupid things like… prayers. Why would we do that, phi!" Veles said as he looked around and saw the mess.

The whole place was torn apart, creating a hole, into space. A vacuum, that started to suck in everything. Yes, a literal hole through the planet!

"Damn, what have you done here?" Veles asks as he looks at the place.

"Emmm.. We discovered negative matter and…. Tokamak, a thermonuclear reactor, specifically reactor number four malfunctioned and…. It had to do something with negative matter generation." Youji said as he looked into his eyes, with him making a face-palm.

"Dear Heavens… Humans playing with something they do not understand…. Like you did with the Nuclear Weapons.." Veles said in disappointment. "I did not come in to just take your soul… I have… A problem to solve."

"And you need a mortal?" Youji asks as he noticed Veles taking a breath.

"Yes. There is a world that is… My sister's school project but… The situation deteriorates, fast." He explained as he shocked Youji.

"What!? You have school for gods!?" Youji asks as he looks surprised.

"Your surprise is… Understandable, Isikawa." Veles said as he sighed. "Back on track though. People in this world noticed that breaking of reality too. This school project was severely overlooked when she was making that world. In short, I need somebody to repair the structural integrity of this world, and I can guide you and tell you how but… You will need to be born in that world." Veles explained as he looked around.

"Why you can't just fix that world if you… Can resurrect me in it?" Youji asked as he looked at Veles.

"Simple question. Would you fix an iPhone, if it got on screws on the back?" Veles asked, making Youji burst into laughter.

"Nah, they will also take your warranty if you will try to repair it yourself," Youji said as Veles nodded.

"Same situation with that world. But these amateur worlds have backup controls… Basically places where you can physically interact with that world when spending time in it. I need access to that panel. It's like… Admin control in SAO's season one computer… You know what I refer to, right?" Veles asks as he explained what he meant.

"Wait wait.. Slavic God of Death is also God of Nerds?" Youji asks as he made him laugh.

"God of Nerds? That's a new one. Must write it in my book of names! Ha!" Veles said as his ego hit him for a moment, making Youji give him a 'just go to the point' look.

"Fine fine… I will resurrect you as a part of the Imperial Family in the strongest nation. The technology there is comparable with the years 1785-1858. So firearms start to appear.. But no planes, they still ride on dragons." He said as he explained the situation.

"But I have a request before you will send me there," Youji said as he looked him into the eyes.

"Shoot. As long as it will be within my reach in that world." Veles said as Youji smirked.

"Make me a girl… Not just any girl though.." Youji said as he made Veles lose hope in this plan.

"You serious, Youji?" He asks in disappointment,

"Yes, Veles.. I am serious. I want to be your typical big titty one-san type of girl… If you get what I mean." Youji explained as he put his hands near his chest and lifted them up, imitating big boobs. "And a redhead.."

"Fine… This much control I have. I will give you the biggest affinity for magic in that world though... Keep that in mind that your 'talent' for it, will not be average… Or prodigal… It will be god-like so control yourself on that." Veles said as he materialized a ring under Youji's body.

"Wait!" Youji yelled out as he looked into his eyes. "I have one more request!"

"What kind of, Ishikawa Youji?" He asked with a serious voice.

"I want to remember everything from my previous life, please," Youji said as he looked him into the eyes as he nodded, granting him this wish.

As his eyes closed, he could feel that his consciousness fell on something.. Something.. Soft?

He opened his eyes and he noticed a roof made out of wood, as he turned around he noticed… A doctor? He could not tell because the noise was so distorted he could barely hear as if he still had water in the ears but that slowly disappeared.

"Ah, you are so beautiful, my dear." He could hear the sweet, caring tone as he turned around. He noticed a beautiful girl in her 20s, with quite a big rack. F-cup to be specific. He moved his legs a bit.

"Hahaha… Energetic, isn't she?" An older man with grey hair mixed with black ones appeared near them.

"Yes, she is true. So, how do we name her?" She asks as she looks at her.

'Wait... Her? So he did make my wish come true?' Youji asks as he looks around.

"Hmmm… Martha… Fitting name for a crown princess, no?" Male asks as he rubs her belly a bit.

"FUCK YEAH, HE MADE MY WISH COME TRUE! BIG TITTIES HERE I COME!" Youji yelled out as he cried loudly, with her parents not understanding what the cry really meant.

"Oh look at that.. Quite strong lungs… There there, calm down. Do not overuse them." He said as he looked at his daughter.

'And so, my own Isekai story begins… Time to be me in this world.'
