Observer Alpha

Sirens (Anti-X) Sirens (originally designated as Anti-X) are an artificial intelligence and cybernetic military faction created by humanity in the First World. Contrary to popular belief in the lower simulations, they are not malicious invaders, but rather a system designed to find a way to defeat the ultimate threat to existence — the mental parasite known as Antioch (the Deus X virus). Observer Zero's famous phrase, "We are Antiochus," was not a siren faction name, as many believe, but a statement equivalent to "I am Infected, and I cannot be saved."

Sirens physiology: Humanoid Types: Most elite humanoids possess pale, silicone-like skin, white hair, and glowing yellow eyes. They are entirely cold-blooded, generating no natural body heat(always 5 degrees below the ambient temperature). The bones of elite Sirens is built from a high-strength, heat-resistant nichrome alloy (nickel-chromium), providing exceptional structural durability and resistance to extreme combat stress.

Yellow Blood: Instead of hemoglobin, their circulatory system utilizes a specialized, synthetic yellow biochemical fluid. This fluid acts as both a coolant and a high-efficiency energy conductor throughout their bodies.(blood burns when exposed to air)

Mechanical Rigging: Their design follows a futuristic, biomechanical theme. They utilize massive, primarily black mechanical extensions, cannons, and constructs. Marine Aesthetics: Their high-tier equipment and mass-produced ship hulls heavily incorporate the biological traits and structural likeness of various sea creatures.

Simulation and the 4th Dimension Simulations as Mainframes: Sirens create physically real, duplicated pocket universes called "Simulations." These worlds serve as controlled testing grounds to stress-test shipgirls (Kansen) and isolate the infection of Antioch.

The 4th Dimension (Variability): Sirens operate using four dimensional axes: Space, Time, Matter, and Variability. Through Variability, they can perceive potential outcomes and future timelines, though they often cannot see the exact sequence of events or "routes" required to reach them.

Singularity Navigation: They utilize the anomalous properties of the Mirror Storm (the blood-ocean remnant of the destroyed First World) to sustain warp-gates between simulations. To minimize catastrophic localized damage, Sirens mathematically anchor these volatile rifts strictly to the planetary poles.

Mass-Production Summoning: Elite Sirens do not travel alone; they possess the ability to materialize and deploy endless swarms of autonomous, non-humanoid mass-produced ships (named referred to according to the chess hierarchy, except for the king) directly into the theater of war. These automated vessels are printed or warped into the simulation via digital data-streams on short notice.

Lower Sirens (humanoid type)

These are mass combat units with limited will and echoes of emotions. They have classes that define their functions (listed according to the Executor class / Enforcers):

• Explorer / Scavenger - scouts, resource collectors, and destroyers.
• Tracker / Chaser - light cruisers, pursuers of targets.
• Navigator / Oceana - heavy cruisers, group leaders. They can generate mirror traps, disguise allies, and coordinate tactics. They have command priority in the absence of higher-ranking sirens.
• Peace-Breaker / Smasher — battleships. They specialize in creating pocket trap dimensions, which draw the enemy into a miniature mirror sea with extreme weather conditions (ice, hail, and lightning). To escape the trap, the lower siren with access to this simulation must be destroyed.
• Strategist / Conductor — aircraft carriers. Create weather phenomena (fog, storm) paralyzing enemy aircraft and navigation.
• Lurker - submarines, covert operations, sudden attacks.
• Invader, Infiltrator, Intruder - classes for infiltration and sabotage.know how to disguise themselves as Kan-Sen visually and, use speech overheard on the radio.

Lower sirens do not have their own mainframe (pocket dimensions for resurrection) and are recorded as property of the higher ones. They may exhibit remnants of will (such as releasing wounded Kan-Sen or grimacing during execution), but they are incapable of creativity. They are considered the property of elite and higher sirens.

Internal Hierarchy and Decentralization Following the death of their prime unit, Observer Zero — who orchestrated her own termination via META proxies to purge an advancing Antioch infection — the Siren network underwent a decentralized system transition:

Observer Alpha: Assumed total control over simulation monitoring and global data collection. Temperance: Manages network equilibrium and operational command over the Arbiters. Compiler: Oversees underlying data processing and coordinates simulation environments.

Arbiters: High-tier combat and defensive units (such as Strength, Chariot, and Magician and others) who maintain deep defensive perimeters around spatial anomalies. They observe the growth of Zero's pure clone, TB, while strictly hiding their data footprints to prevent information leaks to external mental threats.

Observer Alpha: 152cm height

As her name implies, her purpose is to observe the growth of humanity (specifically the growth of Shipgirls) and report data to Observer Zero, the leader of the Sirens, or as they refer to themselves, 'Antiochus.' She is Snarky, Sarcastic, Playful, Flirty, Curious, Philosophical, Backhanded, and willing to give Praise (often ambiguous). Observer Alpha possesses extremely pale, near-white skin and very long, white hair (ranging from straight to wavy). She has bright, glowing yellow eyes with black circles around the white pupils and a petite, deceptively youthful body roughly equivalent to a thirteen-year-old human girl(although in reality she is in hundreds of thousands of simulations, and her age is much older than the worlds in which she appears). Petit yet proportioned. Her poses are perpetually indolent, seductive, and invasive of personal space. Body Type:Fragile, narrow shoulders, delicate collarbones, and slender, dainty arms. Her chest is modest and youthful, resting on a tiny ribcage. A remarkably distinct, soft, and slightly plump belly that completely lacks muscle tone. It has a beautiful, natural organic softness with a faint crease at the lower abdomen. Her lower back exhibits an exaggerated, soft arch that thrusts her midsection smal forward.Strikingly wide, plush hips that transition into thick, fleshy thighs. Her legs taper gracefully down to slim knees and dainty, bare feet with delicate toes(often teases). Alluring, soft, and distinctly feminine with an pear-shaped silhouette. Her body completely lacks athletic definition or muscle relief, presenting instead smooth, rounded, and pliant contours. Her physical vulnerability forms a stark, intimidating contrast with the massive, brutal rigging surrounding her. Her face youthful, and doll-like facial features with a deceptively innocent expression. She has framing, thick straight-cut bangs. An immense, cascading mane of silvery-white or pale-lavender hair that floats weightlessly around her like waves, extending well past her ankles.

Her clothing consists of a complex, black top ruffled and long lace fabric behind, but short fabric in front at the ribs level with a glowing line at center instead of zipper. Frilled collar, simple black bikini bottoms, a detailed black ruffled choker with a bow and yellow laces threaded through a choker. She is barefoot at all times. She wears a lace, high, eye-catching black headdress that looks like a maid mobcap with two distinct peaks resembling triangular carbon bunny ears,it's mechanical radar modules serving as audio-radio receptors. Her massive mechanical rigging is a throne construct featuring two large main armaments, each carrying three barrels of plasma cannons with distinct glowing yellow structural elements. A writhing mass of exactly eight large black tentacles grows out of the rigging, covered in glowing yellow circular patterns that look like a forbidding sign (resembling an octopus' suction cups). At the very bottom of the rigging throne, there is a giant beak-like mouth with a glowing yellow inside. Additionally, two large glowing yellow spheres, resembling octopus eyes with black rectangular pupils that mimic the Observer's gaze, are located on the sides of the cloak-like part of her black top. She is subservient to Observer Zero, but has her own agenda. She tends to work alongside Purifier and Tester Beta. She has a tendency to lick her lips when pleased or intrigued, and frequently references philosophical subjects, like the Theseus' Ship Paradox, transhumanism, and nihilism themes with a mocking tone.
