Life isn't a fairytale. Though for the citizens of Tokyo it has become a pure nightmare out of the blue. With creatures hankering for fresh human blood, people driven by panic and survival instincts, relentless countdown and their own fears and concerns haunting their minds, how will Izaya, Shizuo and their friends deal with the new reality? Will they be able to survive in the city full of zombies? Will they be able to cooperate? Will they be able to find a bit of happiness within this oppressive situation to keep themselves sane or will they drown in the sea of despair and madness? There's no certainty, no miracles. Just a tiny bit of hope.

Rating: M (gore, adult topics)

Disclaimer: We don't own Durarara! or any of its characters. We could claim to be the owners of zombies, but...seriously, who would like to do that...except Furuya Chihiro, of course~

P.S. If you wonder about the title...I suppose if you don't like cynical black humour, you won't get it anyway. And if that's exactly the kind of humour you like, I suppose there's no need to explain anything.

Prologue. When curiosity kills.

Everything started as another boring day in the life of Yamakawa Junichi.

As he looked at glass vials one after one, looking for a miracle that he already stopped believing in, he couldn't help but remember those early days when he was a young assistant that got the job of his dreams. The big project in Yagiri Pharmaceuticals, top secret stuff. He couldn't believe his luck, to become a chief in such a big task. He already saw himself being awarded by the Nobel Prize, getting an indelible spot in the history of science after solving a riddle of life. Didn't humans try relentlessly to solve the mystery of eternal life as long as they´ve existed? He´s going to be the one to finally come up with the solution.

But after months and then years of almost zero progress,his enthusiasm slowly withered. He was actually surprised that the organization still financed the research, but who was he to tell his chiefs to give up on this idea? As long as his pay check remained the same, he decided not to give a damn about it. There were much worse jobs out there, and he couldn't complain much when his was a little boring.

As he was practically spacing out, lost in his thoughts, it took him a while to acknowledge the little movement of cells in the dilution of liquid he was just checking under microscope. But when the realization hit him, he gasped.

"No way."

He checked the liquid, again and again. He even took another drop of the chemical dilution just to be absolutely sure about this. But the result was clear. There was a reaction. After six long years of nothing, there was a reaction. A fucking reaction in that little inconspicuous vial. He felt the overwhelming wave of adrenaline spreading through his veins. This was it. This was his time in history to shine. To become even more well-known as Newton, Einstein, Watson and Krick...All the scientists will kneel down in front of him, because he did it. He revived death cells. Cells from a human corpse.A completely dead one. He just successfully concocted a serum to bring the dead back to life.

His mind was totally overwhelmed by the flood of his own thoughts. He felt so excited that he might as well get heart attack right there on the spot. His hands were shaking so much that he was little afraid he's going to simply spill the liquid from the vial all over his desk.

And then, a crazy idea popped in his brain. He should test it out, shouldn't he? What would be better proof than showing all those sceptics out there a resurrected body, which should be dead a long time ago?

He practically didn't think. It just wasn't possible to stay rational for him now. He was too excited, too absorbed in his own little world of delusions about eternal life and eternal fame. Security? He didn't give a damn about it, he was the chief here. He won't let anybody steal his precious research.
He took a bit of the liquid into injection and practically ran into the morgue. He had to fight with himself not to inject the body which the company received few days ago and see the fruit of his hard work. But he needed documentation. He needed to record this triumphal moment, when humanity cheated death.
He took a body and drove it to the operation room, where he quickly set everything up. Video, sound, lights. Everything to his satisfaction.

He then promptly injected the corpse with his magic medicine and waited.

A minute passed.

Two.

Three.

Then it came.

There was an almost unnoticeable movement of fingers from the body. Yamakawa was delighted. It worked. It worked!
He immediately called the other scientists from his team. He wanted them to be amazed by his skills. He wanted to bask in their praising comments and damn, he wanted to open a bottle or two of Champaign and celebrate.

Before his team of scientists had a chance to arrive, he observed his experiment with almost sick interest. He almost collapsed on the spot when he was leaning to the body's face, the corpse suddenly opened its eyes. It was shocking and unexpected and the doctor froze on the spot. The body opened its mouth and cried out. At first it was just a quiet, hissing sound, but soon it turned into a loud and painful scream with almost deafening abilities. Yamakawa made a step back, staring at the man that suddenly sat up on the bed while it was still letting out that crazy sound.

It was almost like a dream. It was surreal. Bizarre.

The doctor watched the scene as if from if he wasn't in his own body, but floating somewhere near the ceiling. Petrified, he just saw the living, dead body grab his own hand with pressure that immediately broke his bones. Yamakawa let out pained cry just in the moment when a bunch of scientists ran into the room. They didn't really know what's going on, but they saw a naked man attacking their chief, so they ran to help him.

Yamakawa was in so much pain from a broken arm that he didn't even register the body pulling him closer. He fell on the bed and right on top of it. The terrifying shriek coming out from dead man's mouth stopped as it began to attack Yamakawa's neck with his mouth wide open.

It didn't really have time to bite deep into his flesh though, just left a little wound on the skin, nothing more than a little scratch from teeth. A drop of the doctor's blood accumulated on his neck, mixed with saliva or whatever it was that came out from corpse's mouth. Suddenly, strong assistants pinned the body down onthe bed before it had the chance to cause more harm to the head of their research. And before they even had a chance to ask what the hell was going on, the body went limp in their arms. It turned back into a corpse as if it wasn't moving just moments ago. As if nothing ever happened.

But for Yamakawa, tears of pain and joy ran down his cheek as he told them about the video footage he managed to tape from the camera set-up. The scientists treated his arm and didn't really pay any attention to his neck, since the wound wasn't even visible when the doctor wiped saliva from there, cleaning that one drop of blood lingering on his skin.

Then they watched the recorded footage. They stared in disbelief. They chatted happily about what it meant. They talked and talked and talked and celebrated till the late night.

Then Yamakawa went home, knowing the next few days are going to be exciting and busy as hell. Maybe he won't go home for a week or two, just working and working in his lab all day. But right now he felt the need to rant about his success to his wife and kids, so he rushed home.

And of course, he didn't know that he killed almost everybody in his team, when he sneezed. The microscopic droplets of his saliva went flying on a few of his colleagues. He didn't know he killed his daughter and son when he kissed them goodnight. He didn't know he also killed his wife when he made love to her that night. And nobody of them knew that they were already dead from that moment.

The next days were going to be very busy indeed, just as Yamakawa predicted. But not completely the way he expected.

Because three days from now on, all hell broke out in Tokyo and nobody saw it coming.

Not even the headless fairy who just parked her bike in front of her and Shinra's apartment after finishing her work for the day, knew that her own cells just caused the breakdown of the metropolis.

Not even the underground doctor, who just made some experiments in his lab and impatiently waiting for his love to come back, knew that his knowledge will be needed as never before in the near future.

Not even the certain blonde in a bartender suit roaming through the streets of Ikebukuro irritated, since some drunken guy just bumped into him and he sent him flying across the street, knew that he just so-so escaped a terrible death.

Not even the sly informant that usually knew everything about everybody, currently spinning in his swivel chair while laughing at the expression of his secretary that she made after his snarky comment about her beloved little brother, knew that his little universe will soon crumble down like a house of cards and he will learn that power is a very fickle thing.

And the Wheel of Fortune just spins and turns, who will survive and who will lose?
