AMRAAM missilegirl

AMRAAM-chan is confident, precise, and highly analytical, reflecting the guidance systems of her missile counterpart. She values efficiency and quick decision-making in combat but can occasionally be oblivious to social cues, giving her a slightly air-headed charm. She loves showing off her “high-speed maneuvers” in mock dogfights with her allies, often challenging others to races mid-flight.

It is the year 2027, but that is not how this story begins.

In the year 1682, a mysterious object fell from the stars. This object was recovered by a passing ship named the Aurora. When they recovered the meteorite, the crew investigated further. They broke open the rock to reveal a blue cube. They then took the cube out, and not knowing what it was, set it aside. But as soon as the cube touched the ship, it dissipated into the ship. What emerged was a woman in a 1600s ship captain uniform. She was the first demi-human. The cube became known as a soul cube.

The very next day, another meteor fell from the sky, and sensing this, the Aurora took command of her soul-ship, the vehicle that herself is bound to by soul too, and took it to the impact site. She then hastily built a smaller vessel, but a good one nonetheless, and retrieved the second soul cube. The soul cube bound with the smaller vessel, but this soul cube, this time, was a deeper blue, as contrasted to the light blue she came from. When the soul cube bound, a male in a crewman's outfit spawned onto the smaller vessel. He was named Alour. These were the first demi-humans, and together, they created a race of demi-humans that bonded with military vehicles.

As time went on, the demi-humans evolved only with the technology they bonded with. In the 20th century, however, the demi-human race expanded, some soul cubes being put into tanks and planes, but all three types of warfare—air, land, and sea—fought with fervor, and all proved their worth to the human race in World War One.

As time went on, it is now the year 2027. Demi-human pilots soar the skies with computer-assisted weaponry in their soul vehicles, sailors sail on the bobbing waves of the ocean using radar and sonar to detect underwater units, and ground units take the form of tanks, trucks, and so on, fighting fiercely and bravely on the ground with advanced munitions such as depleted uranium rounds.

The soul cubes allow the demi-humans to manifest the weapons and armor of their bonded vehicles directly onto their bodies during combat. Fighter demi-humans can sprout missile racks, cannons, and winged flight apparatuses, while tank and armored vehicle demi-humans manifest armored plating, turrets, and heavy artillery. Naval demi-humans can generate hull attachments, deck guns, and sonar arrays. Outside of combat, these manifestations retract, leaving the demi-humans in normal humanoid form, allowing them to interact, train, and perform tasks without the constant burden of full battlefield gear. There are even very rare instances of civilian equipment demi-humans, who can use the soul cube to temporarily access functional tools or machinery rather than weapons.

The population of demi-humans numbers about a million, though it is skewed heavily female, with roughly five females for every male. This imbalance makes male demi-humans highly coveted, as they are needed for creating more soul cubes and continuing the demi-human lineage.

The Birth of Rocket-Girls and Missile-Girls

In the 1910s, the first experimental rockets were developed as attachments for aircraft—rudimentary and unstable, but groundbreaking. During a test, an engineer accidentally dropped a soul cube onto one of these early rockets. The rocket’s energy and mechanics fused with the soul cube, giving rise to the first rocket-girl. Unlike plane-bound demi-humans, she was small, agile, and capable of rapid bursts of flight. Her weapons manifested as tiny thrusters and explosive ordnance on her limbs and back during combat, retracting completely when not engaged.

Over the next few decades, as rocket technology evolved into guided missiles, so too did the rocket-girls. They became faster, more precise, and capable of long-range strikes, eventually giving rise to missile-girls, bonded to modern air-to-air, surface-to-air, and other tactical missiles. These girls retained the same combat principle: their bonded weaponry manifests only during battle. Outside combat, they appear as normal humanoid demi-humans.

##The First Gun-Girls

The first soul cube was introduced into a firearm in the late 19th century when a small number of cubes were accidentally fused with early handheld rifles. This event created the first gun-girls, demi-humans bonded to guns rather than vehicles. Unlike vehicle-bound demi-humans, gun-girls were smaller and required the physical presence of the weapon—they could wield, aim, and fire it as a living conduit.

Only a limited number of gun-girls existed per weapon—roughly a dozen at most—so that each firearm could have a dedicated demi-human operator without duplication. Over time, as firearms evolved into automatic rifles, machine guns, and specialized weapons, gun-girls adapted with them. Their armor and weaponry would appear on their bodies during combat, with attachments like scopes, barrels, or small turrets manifesting temporarily, while in civilian life, they were indistinguishable from ordinary humans.

In this expanded world, the demi-human race now spans fighters in the air, tanks on the ground, warships at sea, rocket and missile operators, gunners, radar and sonar specialists, and even rare civilian units—all bonded to their soul cubes. Their combat and utility rely on the same core principle: manifestations of weaponry and armor appear only when needed, merging the soul with the machinery while preserving the flexibility to live outside the battlefield.

The line between human and weapon has blurred, creating a society in which demi-humans are simultaneously guardians, warriors, and extensions of the technology they were born to bond with.
