It happened in the year 2030.

A meteor impact rocked planet Earth. Nicknamed Mikaboshi, its trajectory had seemingly been on track to pass by Earth harmlessly... until, in a manner completely unpredictable, it changed course.

The resulting disaster cast up an enormous plume of debris that darkened the sky, triggering massive climate change among other devastating effects. Flooding, widespread crop die-off, starvation and destruction all plagued mankind. And yet the governments of the world managed to band together, in widespread agreement to do all they could to weather a truly devastating storm.

Perhaps this show of solidarity and unity would have worked, if not for the threat that rose from the darkness.

The sun blotted out, humanity in disarray, it was the perfect time for them to strike. Legends of vampires had long persisted throughout different human cultures across the world, and it was not long after the attempt to unify humanity in the face of devastation that they struck. Stronger, faster, and capable of regeneration and feats of incredible supernatural, mystical power, vampires were able to subjugate much of humanity swiftly, killing many adults and taking children to raise them as cattle for a continuing source of blood.

This is why they were called the Red Years.

A combination of the natural disasters caused by Mikaboshi's impact and the war against the vampires wiped out an enormous amount of the adult population of planet Earth. And no small number of children were taken to effectively serve as a blood farm for the new vampiric rulers of much of the planet.

And yet...

A portion of the East Coast of the United States. A fraction of the Isle of Britain. One of the deepest parts of Russia. Part of the Japanese island of Honshu. These are just a few of the places that remained under human control. Perhaps the vampires were turned away for some reason. Perhaps they felt they did not need to take this places. Whatever the reason, they persisted.

And when the skies eventually cleared, four years later, humanity was able to begin progressing once more.

Buildings were rebuilt and refurbished, refit to serve as residential centers and places of education, places of scientific progress and military development. Contact between the remaining human-held parts of the world was established, however loosely, and some knowledge was able to be shared between them.

But there was still no way to reclaim what was lost, to rescue the people being used as a farm by the vampires. Attempts at reverse-engineering the vampire's strange weaponry resulted in disaster. While it was possible to wield the newly-developed weapons, they had to be supplied with vampiric blood to function and would begin to vampirize the wielder extremely rapidly, draining their entire body of blood... or even worse potential outcomes.

That is, until a sudden breakthrough was made.

Yukimura Angelica, a prodigy and researcher into the reverse engineered weaponry(dubbed "Crimson Arms") discovered a formula that, with monthly injections, enabled their safe usage. With Crimson Arms loaded with cartridges of vampire blood, and the new formula, VBS-108, humanity was able to make their counterattack, venturing into vampire territory, raiding one of their 'farms', and rescuing a number of children and adults.

Such raids are few and far between due to the danger involved, but the mere fact that they became possible was a massive step forward.

Now, recruit, are you ready to begin and fight for humanity's future?

So this is a new concept inspired by a few different anime and manga and video game franchises, primarily Owari no Seraph and Code Vein. Taking place in the not incredibly distant future of 2046, in a world devastated by a meteor impact and also vampires. Nature might be springing back, and humanity may have managed to barely weather the storm, that was only the beginning. The human race must fight for their future, or be crushed in darkness!

Given the anime inspiration, I decided to set this RP specifically in the Japanese region, but given the circumstances some characters may be from elsewhere.

• The State of the World: Ruined cities growing overgrown with recovering plant life, the gothic architecture favored by vampires in some places, a sign of the massive underground complexes favored by their kind. Still, it's not all grim. Human-held locations are clean, with schools, unfortunately somewhat cramped residental areas, and large military and science installations for development of strategies and weapons against the vampiric threat.
• The Army of Humanity: The collective name of the military arm of the remaining strongholds of the human race. Composed of soldiers recruited from promising individuals in the education system starting from the age of 16 due to the necessity of maintaining a fighting force against the vampires, they are armed with Crimson Arms. The elite of the Japanese unit are known as the Red Demons, and recruitment to the Red Demons requires extremely high aptitude with a Crimson Arm. The Red Demons get special Crimson Arms, capitalizing on this high aptitude. One of the most famous of the Red Demons is known as Lady Shinigami, with a thousand vampire kills to her name.
• Legacy: The governing body of vampires across the world. Legacy is ruled by a secretive figure, who has assigned high councils of ten of the eldest vampires to preside over every region on earth. Their primary motivation is maintaining a steady supply of blood by 'farming' humanity, though many vampires are particularly callous and prone to killing humans to satiate their bloodlust. Legacy's inner workings are deeply mysterious. The Japanese branch of Legacy is currently headed by a particularly capricious High Council that seems to be testing humanity's defenses to find a weakness...
• Vampires: Unaging, immortal supernatural beings that feed on human blood. No normal food satisfies a vampire, and thus they must feed on the blood of humans. Possessed of numerous mystical powers, they can also regenerate from virtually any damage, even including decapitation. It is only through the absolute destruction of the entire heart, or the use of a Crimson Arm, that it becomes possible to permanently end a vampire's life. The typical armament of a vampire is a weapon powered by their own blood, the basis of the Crimson Arms. More powerful vampires may also have unique supernatural abilities. In appearance, most vampires resemble humans and feel the same emotions, but exhibit pointed ears and red eyes as well as pale skin. In the past, the sun burned vampires, but it seems as if that may not always be the case...
• Blood Beasts: Genetically engineered monsters created by vampires through a use of technology and mysticism as a sort of shock troop. The exhibit some traits of vampires, such as feeding on blood and regeneration from most harm. However, they are simple beasts and thus lack intelligence, requiring the direction of a vampire to perform as a serious threat. That being said, they are still large, incredibly strong, and hungry for blood.
• Crimson Arms: Weapons created by reverse-engineering the mystical blood-powered weaponry wielded by vampires. Capable of slowing vampire regeneration and rendering it possible to kill them, Crimson Arms are powered by cartridges filled with vampire blood. There are standard-issue Crimson Arms, but also more unique and powerful weapons with more advanced capabilities reserved for those who exhibit a particular aptitude for them. Crimson Arms threaten to devour human wielders or worse, but by use of the formula VBS-108 it is possible to wield them safely with a monthly injection.
• Vitae Biocompatibility Supplement 108: VBS-108 for short, this is the formula developed by the prodigy scientist Yukimura Angelica. By use of this formula, it is possible to negate the negative effects of wielding a Crimson Arm entirely, though monthly injections are required. Without any known side effects, it has had full approval by the various governments across the world. Highly regulated, VBS-108 is administered in exact doses to the soldiers of humanity. In spite of its importance, the actual ingredients of VBS-108 are entirely unknown...

As a bit of a last comment, I'm currently undecided as to if I will have the vampire side as playable antagonists as well. Please give an opinion if you're interested in the RP! For now...

Players are intended to be fresh recruits into the Red Demon arm of the military, please talk to me if you want to play a character who has been a part of the Red Demons for a longer period of time! I'm willing to permit it, but I still want to know what you have in mind!

Well, you know that I do have some interest in the vampire side and how it's portrayed. :p

Will get a character up in the next few days, ideally! Question: Most of us will be fresh recruits, and the training starts at 16. Does that mean the default character age for the RP is 16?

@Zoey Boey: For fresh recruits, yes.

If you want to make someone who's been in the Red Demons a bit longer, you can, just talk to me about it first.

I'm interested but I'll see if my concept gets the go ahead first.

So I was thinking of my character originating from the deepest parts of Russia. The concept being that the winters of that part have very little sun to begin with, so every winter the vampires would come in small numbers for feeding. Not enough to alert the rest of the world. (Inspired by 30 Days of Night.) A few families tried resisting, but resistance meant more lives taken. Still, with persistence they were able to take down a some over the years the old fashion way, destroying the heart.

My character would try to replicate his approach in reverence of his towns history. Using a Crimson Arm flamethrower to weaken the vampires then use a blade for the heart. I also envision him in something similar to a Warhammer Space Marine get up to content with their super strength a little bit better.

I would also say I would prefer my character be 18 at least, because of the dark and likely violent nature of the story. Either way let me know if the concept seems alright for your story.

@Jumbus: Hmmm, I'm not quite sure that's going to fit too well. Certainly you can make him an older member of the Red Demons, but Crimson Arms already effectively function to help their wielders fight vampires effectively.

Here's my character. Let me know what you think!

I love owari no seraph so im very interested in joining this rp!! Also would be very interested in playing a vampire/antagonist role :)

Is it possible to make a character who would be the child of previous Red Demon members or researchers working with Angelica?

@Zoey Boey: I'll looking over this in more detail tomorrow, but I'll point out that the Red Demons all have unique Crimson Arms, so even if it's gun-based it's going to be a lot more elaborate then a regular assault rifle.

@Pink Khione: That would be fine, just let me know the details you have in mind.

Edit: Will probably pull out I think I misunderstood this RP for a more standard vampire hunting things. Best of luck with it though.

@VitaVitaAR Looking forward to it!

How elaborate are we talking? Like...a transforming gun? A gun that is secretly two guns? Or a gun with a grapple hook?

I think people might be misinterpreting just what Crimson Arms are.

The Red Demons all have unique and powerful Crimson arms because of their high aptitude, that's how someone gets recruited to the Red Demons in the first place. You won't get generic stuff with only a single function.

@Zoey Boey: Transforming gun, gun that's also a sword, that kind of stuff. You can get pretty nuts. They're based on the crazier weapons in Code Vein and the more tame in design but still pretty crazy weapons in Owari no Seraph.

@VitaVitaAR Okay, yeah, I wasn't sure about that. From the lore I thought it might just be special bullets or ammunition that makes a Crimson Arm a Crimson Arm. I also thought the Army of Humanity was like, a regular army with vampire killing bullets. Are we supposed to be like super anime badasses or something? I figured since our characters were 16 we were just pretty normal people.

@Zoey Boey: Crimson Arms are reverse-engineered from the vampire weaponry, so they're definitely not just normal guns. Not everyone has to be 16 I just want people to talk to me about their plans if they're not a fresh recruit.

Even if they are, remember this is the elite arm of the Japanese branch of the Army of Humanity. They're already going to have some training since you get some combat training basically by default in-setting, and exhibit high enough aptitude(though this means ability to use them and not skill with one to be fair) with Crimson Arms to get there in the first place. Crimson Arms are effectively magitech weapons of varying types, they're not regular rifles even when they're guns.

I cite Code Vein and Owari no Seraph as influences, both of those have pretty good examples of what I intend combat and weapons to be like.

@VitaVitaAR I see I see.

I never played Code Vein and Owari no Seraph so I wasn't sure what those games were like.

So, military service is mandatory in the setting? At least in some form, not necessarily going out on Raids of course.

@Zoey Boey: To some extent, given how important it is. If you have the aptitude for Crimson Arms, you're at the very least heavily recommended to enter combat duty, and you're pretty much guaranteed to end up in combat if you're on the level of the elite units in aptitude(like the Crimson Demons) simply because people like that are so valuable for fighting vampires.

@VitaVitaAR Makes sense!

Is aptitude a born thing? Like a certain amount of the population are just born with like the ability to use Crimson Arms good? Or do you mean aptitude in just a kind of broad sense, like some people have an aptitude for programming or carpentry.

I think this is my last question, lol. Then I'll go rewrite my character's backstory (I'm assuming I should do that?)

@Zoey Boey: Well, it's a bit of that but also a bit of metaphysical thing since they're in part magical. I think a good comparison would be like someone having a naturally good sense of smell. It's something you're typically born with but I won't rule out someone developing it.

@VitaVitaAR Okay i edited my character sheet. I made changes to her backstory and to her weapon.
