Ever since the November, 16, 1998. After Yuno Gasai have rose to prominace, more people wanted to see the real Yandere themselves... Even the first Yandere, Yukako Yamagishi from... Ahem, Jojo, Dimond is Unbreakable... Were jealous that Yuno has taken the yandere queen throne.

However, after some mad Otkaus and Weeboos, who've escape from a mental asylum... Raided a Research Center and created a fog of the mixture... Japan is now a past of it's former glory. 

With dimension of the other worlds, who also hit by it. The Afflicted became the very threat we're facing...

The Yanderes.

While the lunatics cheer and created their own religion for them... Majority of the population of Earth, however... Is now in a state of chaos and fear by them. National Guards been slaughtered, Militias and Minutemen's been overwhelmed, and Countries, such as...

Tokyo, Capital of Japan, has built a wall and the surrounding areas with walls, mines MG nests and Garrisons. Hoping for help...

Hà Nội, Capital of Vietnam was taken and the Government was forced to flee to HCM. And Đà Nẵng, is taken by the Yanderes, with mass emigration.

Shanghai, with a lot of male population and Soldiers gone missing, a once pride and capital of China, is now a ghost city, with only a small group of Chinese Scavengers trying to survive. 

Vladivostok of Russia was once a peaceful city, now a battle of between both the Russian Military and Militias against the Yanderes. With neither side having the advantage.

Indonesia and Australia, was now on a fight for survival. To make sure that they will never have a foot on their country.

South Korea, mass panic, riots and emigrations has made it hard for the ROK Military to Call to Arms.

North Korea, while military elite cheered for the fall of ROK at first, but, karma is real and it came for them.

And Hawaii of the United States, mass evacuation, along with Pearl Harbor. Has cause mass panic and riots have broke out...

But, all hope is not lost. After an emergency United Nation Meeting, regarding of the yanderes. Many nations, supported a new organization was needed. One that will fight to ensure the fate of humanity will be safe, whatever it takes.

Armed with weapons and gear, so effective, they were often called 'The Spartans of United Nations.' They're often the first and last line of defense, against the Yanderes or any subtype of them. Even against those who hurt themselves for their senpais, willing to worship or even sacrifice their lives for them.

No matter the threat, how dangerous the place is, or how many yanderes there is... These Valiant and Brave Young Men, with the Veterans, training these young men to become...

The Yandere Fireteam.

At December 16, 1998. After the prominence of Yuno, and the rise of Otakus, couple of the United Nations Councilmembers, got concerned about the possibility of insane Weebs. But it was underlooked.

But at May 23, 2019. With the Yuka Takaoka incident, their fear has started to come true. It was originally formed as the Yandere Special Investigation Unit.

"In the criminal justice system. The U.N. Justice System are represented by two separate yet equally important groups, the U.N. Agents who investigate crime, and the International Court of Justice attorney's who prosecute the offenders. These are their stories."

[DUN! DUN!]

With reports of Yanderes and obsessive girls, going for the breaking in and making meals for their senpais. The Agents were able to arrest and prevented more than 80% of the Yandere Crime. Earning the new found hatred by the lunatics.

" It wasn't easy to deal with them... They're willing to fight until their final breath, or their bloody lover dies with them... We're now 20 left compared to 80 of us..." Special Agent, Elliott Gales.

Despite been able to arrest 20 Yandere, a total of 60 U.N. Agents were killed by them.

Despite it, is was a proven success after reports of Japanese Teenagers felt much safer when they're protecting them. Nations are happy that the Agents were able to quell the crime, despite the Agent's severe casualties. 

As the Yanderes became more aggressive or even evasive, the U.N. Agents continued on the hunt, with new tactics, new weapons and gears. That's what the current Yandere Fireteam is using.

Until the disaster struck. Leading to the Rise of the Yandere Fireteam.

Often go with three to four members, they're mostly from the Marine Corps of the entire globe, or even from the Special Forces of the Militaries. They're often sent to areas of high threat or areas with a lot of yanderes and high attrition rate.

They're often the Best of the Best who'll fight against the Yanderes.

Recruits, often civilians. Were taken to a rigorous training and martial arts, by lotteries. Just like the U.S. Army, they're also given a job opportunity, at most if they're honorably discharged.

Those who are unsuccessful, were often relegated to the U.N.'s Mobile Infantry.

Combined with the Remaining Agents and survivors of the afflicted areas and nations. They make up a powerful fireteam member, each with their own six classes.

Gunner Class are often the common boots on the ground Fireteam Member. Armed with good firepower and gears, they're the Jack of All Trades of all Fireteams. With their Overclock skill, they can improve their team's Reload Speed and Rate of Fire of their team's weapons. Some of the Fireteam's Gunner turned their Standard Issue Grenades into Incendiary Grenades or even turned it into a C4 Grenade.

The Technician Class with their Handguns and CQWs (Close Quarter Weapons) are often at risk against the yanderes. However, they have their Auto-Turret to protect their backs. Been able to use the Charged Coils to slow them down and weaken their capability, Technicians can upgrade their turret's Caliber from 7.62x51 NATO to .50 BMG. Greatly slows the turret's firing rate, but it will hit like a train. Or turn it into a flamethrower turret for small enemies or enemy crowd control.

Demolisher Class is the Muscle of the Fireteam, armed with Assault Rifles and Heavy Weapons. With their Micro Rockets attachment on their backs, to cause heavy casualties, or additional damage to more powerful Yanderes. And their concussion blast, used to make the Yanderes to keep distance, and disorient them. Some Demolishers use Concussive Rockets or Napalm Rockets, while cause less damage than the Standard Issue Shoulder Mounted Rockets, the Concussive Rockets can knock down Yanderes, while the Napalm can create a pool of fire for you and your Fireteam, to relocate or escape.

Doc Class are the Guardian Angels of all Fireteams, armed in the same manner as the Gunner, with the exception of their secondary, replaced with pistols. They have a few Combat Stims that can improve other Fireteam's accuracy, stability, stamina regen, and movement speed. It's their Trauma Station that'll be their one and only saving grace, combined with the Medical Nanotechnology, and medical A.I. The Trauma Station is the Doc's only hope for medical assistance, making Doc an important member to protect. Other Fireteam Doc's can turn it into a Painkiller Station, that can reduce the pain and improve other Fireteam's weapon stability, at the cost of lower energy, or into Suppression Station that can slows the Yanderes, with the added bonus of damage, and increased radius.

Recon Class are often the eyes and ears of the Fireteam. Armed with the same manner of the Gunner Class. Unlike the Gunner though, Recons have Parameter Uplink Spectagraph or PUPS, the PUPS Drone and it will scan the area, revealing any hiding Yanderes. They can also deploy a support drone, that can resupply Ammo, boost other Fireteam's accuracy and stability, or even restoring a small amount of vitality for them. Recon's and improve their drone to make them target a specific Yandere, revealing the Yandere and making them more vulnerable. Or a defensive type, that not only slows them, but also damage and stun them.

Phalanx Class are the defensive member of the Fireteam, armed with only pistols and CQWs (Close Quarter Weapons).  Their Shields can be used to block a lot of damage, however, they'll have to use a Pistol or short CQW. But with the Shock Pulse, they can stun the Yanderes surrounding the Phalanx, and daze the one who hurt the Phalanx. Giving them a chance to deal with the Yanderes, or make a quick escape. While the Shield can't be changed, it can be improved. Shock Pulse is just the same as the Demolisher's Rockets. They can make it into a Concussion Pulse, which can knock the Yanderes backward, but will lose the Shock Defense. The Shock Barrier will sacrifice the stun area and area damage, for 33% damage resistance, and stuns anyone who attacked you for a longer period, with additional damage.

However, with the Arms Race of the Yanderes and the Insane Weebs, we too have to play the same game.

Shipgirls, with their riggings and Planes. Yandere Soldiers with their guns. Witches and Female Medieval Knights, T-Dolls of the G&K and other kinds, has lead to the need to tactics against them.

It's Organization itself is not the only part. The Supporting Establishments played the role of recruitment, training, R&D, administrative and logistical duties.

While the Recruitment of self explanatory, for the training, all of them were trained in the ways of the U.S. Marines Corps. However, the drill sergeants of the Fireteam are not forbidden to swear at their recruits, they are the old school, tough as nails Drill Sergeants. As their role is to break them down and mold them into tough as nails Fireteam. Each were trained in their Standard Weapons, M41A2 Pulse Rifle and M39 Submachinegun, they all start as Gunner Class. Those who wish to go as an another class will have to take extra training with their new gear.

R&D Department were tasked to develop new Weapons and gears for the Fireteam Armed Forces. For Research, they worked on the Yanderes, types of hostiles, and potential vaccine or cure for the Yanderes. But, they've been building space stations and colonies on the moon and even Mars. This is the only last option, for all humanity, should the Yanderes overpowers the U.N. Armed Forces and the Fireteams, with the evacuation finished, all nuclear warheads will be activated, in all nuclear nations, and wipe Earth from any lifeforms. The early form of Exterminatus.

Administrative Department, not only provides jobs for refugees of the Yandere Affected Nations, but also monitor the Yandere's progress, provides Insane Otkaus Hunts, that can yield great rewards for those who captured to killed one of the insane Otkaus or Insane Weeboos, which is rare to find as they operate behind the dangers. And businesses that can provide resources and support to the Fireteam.

Logistic Administration, make sure all Fireteam Forces and other Administrations are supplied to prepare for the downfall and Emergencies. Often prepared an average amount of Space Rockets to evacuate often, only important personnel... But with the help of SpaceX Rockets, more less important or even some important civilians can escape. They also planned make a spaceship that can evacuate more and more people, while conserving resources and preventing errors. One mistake can be a disaster, with the Rocket exploding or get drifted into the never ending space...

70% of the Fireteam members are often working as Administrative member than Fireteam armed forces. Due to logistical problems, and searches for the Terrorists of the Disaster.

Whatever awaits humanity is unknown... Will the Fireteam succeed in stopping the Terrorist of the Yandere Disaster? Will humanity have to escape Earth as the place they once called home? Will there be peace between both Yanderes and Humanity? Or... Nobody wins and everyone dies? But whatever it takes, they only have one goal.

Defend Humanity and Earth.
