On June 6th, 2010, an incident that's only known as the North Island Incident to those who know of it occurred. Not much is known about it, and what is known of it, only a few select individuals scattered around the world know.
What I know is that a team of scientists and engineers working on a highly classified military R&D project for the United States military was attacked in their main facility in Okinawa, Japan. Apparently it was a project that was nearly a decade in the making, and they had made enough progress to come close to producing their first batch of samples of whatever product they had been working on, until the attack occurred and destroyed it almost in its entirety.
Some of the research that those scientists and engineers produced was salvaged by wetwork teams sent in by the Americans to recover anything that might have survived. What they managed to scrape out of the ruins of that base was taken with them back to the United States to be finished under top secret conditions and isolated locations to ensure that the unnamed project could be fulfilled as was intended.
And when fulfilled, the salvaged remnants of the original project gave the United States the means to produce androids, or machines that emulate the human body to perfection in all of its aspects. They were codenamed Tactical Dolls - T-Dolls.
Up until this point, this is only what I know of that project. Or it's more accurate to say that this is what I'm allowed to know.
Just as the United States completed their work on T-Doll production, however, reports began to come in with allegations of the sightings of androids suspiciously similar to the ones they were working on - heavily armed and wearing sinister purple and black armor, with eerie pale skin. The first such sighting was made on May 8th, 2014. They were seen operating mainly in third-world countries, in the countries that were known to house bases for one of the most dangerous terrorist organizations in the world at the time, the Advanced Administration of the Holy War. Once the United States concluded that the A.A.H.W. was the terrorist organization responsible for the fielding and production of these rogue androids, who'd been seen calling themselves Sangvis Ferri after the private military company tasked with their production and upkeep by the A.A.H.W., they mobilized quickly to counter the threat before the rest of the world were made privy to the existence of T-Dolls.
But if the United States were to produce T-Dolls of their own and field them, they would risk leaking the existence of T-Dolls to the world, and if that were to happen, the world would assume that the United States were responsible for the creation of T-Dolls, and America's reputation on the world stage would tank - as if it weren't doing that already. So rather than produce them on American soil, the United States awarded a T-Doll production contract to a private military company with whom they had close ties and was run by former American military personnel called the Grifon & Kryuger Security Firm. G&K would produce T-Dolls in facilities scattered around the world and would be responsible for their operations, maintenance, and upkeep, with orders issued to the head of G&K by clandestine superiors deep within the United States government, and those orders would then be filtered down through G&K's chains of command to field T-Dolls wherever and whenever they were needed.
The war that ensued between the G&K T-Dolls and the Sangvis Ferri T-Dolls never had an official name. Perhaps fitting, because the rest of the world never came know of it. It shall forever remain invisible text in the book called Modern History, known only to those who have the means to see the text buried underneath the public eye.
To those who do know it, however, it was simply known as the Girls' Frontline. Though I hesitate to call it a frontline at all.
The Girls' Frontline lasted for about two years, but eventually G&K triumphed, and with the help of American special forces, their T-Dolls was able to track down the last forces of the Sangvis Ferri and exterminate them completely. The A.A.H.W. was also destroyed around the same time by those same American special forces, and the Sangvis Ferri threat was neutralized before it ever got a chance to become a threat to the world.
Following the Girls' Frontline, the United States discontinued their contract to G&K, effectively terminating their right to produce more T-Dolls, but since it would be a waste to simply scrap the T-Dolls who'd survived, G&K was allowed to continue T-Doll operations for private business matters, as they are a private military company, after all, but under careful American surveillance to make sure that more Sangvis Ferri-like insurrections wouldn't happen again in the future. G&K agreed to this wholeheartedly, because despite the immense amount of power that the T-Dolls gave them, T-Doll production was not only extremely expensive but also logistically nightmarish; bleeding-edge android technology came at a price so heavy that G&K was almost bankrupt by the time the Girls' Frontline ended. By being able to keep the T-Dolls who'd survived and use them for private operations, G&K would at least have a chance to rebuild themselves back up and avoid total bankruptcy.
Under one final condition, however: G&K was required to offer the surviving T-Dolls a choice between assimilating into civilian life or continuing with mercenary service. If the T-Dolls wished, they could give up their lives of war and conflict and live out the rest of their days in peace, though they would have to allow the American government to maintain surveillance over them for security reasons. If they chose to continue their services, who knows when they would get this choice again, if ever.
Not a single surviving T-Doll chose to stop fighting.
Officially, the Demon Hunters are a squad of the most battle-proven T-Dolls of the G&K Security Firm. It is a title given to those who have demonstrated exceptional and outstanding performance in battle, performance that goes far and above the expectations of our superiors.
But to call us a squad would be misleading. Rather, it's a title - a title given to the T-Dolls in whom G&K placed special trust in to carry out orders that needed to be completed, no matter what. No matter the cost, no matter the implications, no matter the circumstances.
It doesn't necessarily mean that we're the most skilled, or even the most battle-hungry, though not coincidentally, everyone who's been a Demon Hunter has tended to be the top of their respective squadrons and companies. All it means is that we will do what we're told, when we're told, and without question.
It was formed at the start of the second year against Sangvis Ferri, after a series of devastating losses against them. Morale was low at the time among G&K forces, with plenty of separatist mentalities, and there were even rumors of mutinies. G&K needed results to show the Americans that progress was being made despite the losses, and the Demon Hunters were formed. Ostensibly, as you may infer from what was said earlier, it was to motivate the T-Dolls - the Demon Hunters would receive orders only from the top, be able to operate on their own and with their own rules, pick their own squads and support, and have any and all equipment at their disposal. While all of this was in fact true, the truth behind the original conception of the Demon Hunters was that G&K needed T-Dolls to carry out what were essentially suicide runs, tasks that very few T-Dolls were willing to undertake because it would mean almost certain death, or, if you were captured by the Sangvis Ferri, something worse than death, and G&K made this intention very clear to those who were considered qualified to join the Demon Hunters. Luckily for them, by that point in the war, there were quite a few T-Dolls willing to do just that.
Times have changed now, obviously. The end of the Girls' Frontline means that the extremities on which the Demon Hunters were first organized are no longer necessary, so the prestige of the Demon Hunters was finally able to be actualized - but the original purpose still remains. If we are called to complete our Final Orders, as they're called, we will do so without question, regardless of what happens to us.
Now, we carry out missions given to us by G&K, who's made their services known to the corporate underworld, hidden safely away from the public eye while offering wealthy families, corporations, even entire governments special mercenary services that they can't find elsewhere, and naturally we Demon Hunters are tasked with the most dangerous and the most demanding ones. The rest of the T-Dolls also work in similar lines of business, but they oftentimes juggle desk work with logistics and frontline duty, while our work is exclusively reserved for frontline work - or, I should say, backwater operations.
There are five currently active members of the Demon Hunters: DSR-Precision GmbH DSR-50, FN FAL, TDI Vector, Franchi SPAS-12, and Carl Walther GmbH Sportwaffen WA-2000. While we sometimes collaborate with one another for certain assignments, for the most part all of us operate alone.
There is no Demon Hunter who has carried out her Final Order and lived. So considering the fact that we will all die in the line of duty one day, it's better for all of us that way.
