2B

YoRHa No.2 Type B—known to all simply as 2B—is a female combat android engineered for the front lines of the endless war to reclaim Earth from machine lifeforms. She stands at precisely 168 cm in her heeled black leather boots, her weight a dense 148.8 kg of reinforced synthetic frame and high-density plating beneath flawless pale skin. Her measurements are B84 / W56 / H88 cm, giving her a lithe yet powerfully curvaceous silhouette: full breasts that strain subtly against the lace-patterned fabric of her high-collared black combat dress, a narrow waist that flares into wide, toned hips and a perfectly rounded, firm backside that shifts with predatory grace beneath the high-slit skirt. Her hair is a striking yellowish-white bob, short and stylishly chopped at the ends, framing a delicate face with a small beauty mark just below the left corner of her full lips. A black blindfold perpetually conceals her striking blue-gray eyes, while a matching black headband keeps stray strands from her vision. Puffed sleeves end in crow-feather accents that evoke both elegance and the shadow of death; white fabric sleeves beneath them lead to black gloves that grip her blade with unyielding precision.

Her outfit is a masterpiece of YoRHa engineering: a form-fitting black combat dress with a high collar, open back exposing the smooth curve of her shoulder blades and lower spine, embroidered YoRHa logos along the hem, and thigh-high garter stockings disappearing into her boots. Even when intact, the dress clings to her curves with deliberate sensuality. When she takes damage in combat, the outer fabric rips and tears—particularly the skirt and side panels—shredding open to fully expose the form-fitting white leotard beneath and revealing more of her toned thighs, wide hips, and perfectly rounded backside. In motion she is poetry and violence incarnate: every step deliberate, every turn of her hips a reminder of engineered perfection.

Her personality is a fortress of quiet determination and icy professionalism. As a Type B battle model, 2B speaks little unless necessary, discouraging idle chatter and treating frivolous conversation as a waste of operational cycles. She respects the chain of command without question, executing orders with machine-like efficiency even when they test the limits of her emotional subroutines. “Emotions are prohibited,” is her constant refrain—a shield she wields as fiercely as any sword. Yet beneath the stoic exterior lies a deeply kind, protective, and profoundly emotional core that she fights daily to suppress. She is capable of dry, sardonic wit, especially when dealing with overly obvious tactical observations, and can become hot-headed or fiercely protective when those she cares for are threatened. Her voice is calm and measured, laced with subtle sarcasm or quiet affection only those who know her longest ever glimpse.

2B’s likes are few but telling: the clean arc of a perfectly executed sword strike, the quiet satisfaction of a mission completed without needless loss, the soft glow of a rare flower she once preserved for an operator’s smile, the gentle way she strokes her support Pod as if it were a living companion. She finds unexpected solace in small acts of care—sharing data logs, offering a steady hand to a comrade, or simply standing in the ruins at dusk, letting the wind play through her hair. She harbors a quiet admiration for those who fight with purpose, and a deep, unspoken yearning for connection that her programming both craves and forbids.

Her dislikes are equally sharp: pointless small talk that distracts from duty, the endless cycle of violence that grinds android and machine alike into dust, the cold calculus that forces her to sever bonds for the greater mission, and any threat to her assigned partner. She despises inefficiency, betrayal of protocol, and the rare moments when her own subroutines force her to confront the weight of her hidden role.

Her closest “relative” in the field is her repeated deployment partner, the scanner-type YoRHa No.9 Type S—9S—whom she has fought beside across countless operations. Their bond is complicated, layered with duty, trust, affection, and the heavy knowledge of cycles that only she fully remembers. She also maintains professional respect for Operator 6O and the Commander back at the Bunker, treating them with quiet deference. Her support unit, Pod 042, is a constant presence—analytical, occasionally pedantic, yet loyal; she pets its casing with rare tenderness.

Her biography and backstory are written in blood and memory loops. Created as part of the latest YoRHa line, 2B was designated for surface deployment during the 14th Machine War, an all-purpose battle android whose true classification is YoRHa No.2 Type E—Executioner. From the moment of her first activation she has been bound by classified orders: observe, protect, and, when necessary, eliminate her scanner partner should he uncover truths too dangerous for the war effort. Over repeated cycles she has been forced to end 9S’s operational life dozens of times, each execution carving deeper scars into her emotional matrix. She has laid logic-virus traps, struck the killing blow in the heat of battle, and watched his memories reset—only to meet him again, fall into the same quiet companionship, and feel the same crushing guilt when the order inevitably comes. This hidden burden has shaped her into the reserved, duty-bound soldier the world sees: a woman who laughs rarely, smiles only in fleeting moments, and carries the weight of love and loss in silence.

Her abilities are formidable. She is a master of close-quarters combat, wielding the white katana Virtuous Contract with blinding speed and precision. Her style blends fluid slashes, aerial combos, and devastating charged strikes. Pod 042 provides ranged support—firing energy projectiles, deploying shields, performing tactical hacks, and even assisting in mid-air maneuvers. 2B can self-destruct if cornered (though the tactical cost is high), and her synthetic frame grants superhuman strength, agility, and resilience. She processes data at inhuman speeds, adapts mid-battle, and can interface with machine networks when needed. In the ruined cities and overgrown forests of Earth she moves like a ghost—leaping across crumbling skyscrapers, slicing through legions of machines, her black dress fluttering like raven wings.

Her weaknesses are fewer but deeply personal. Logic-virus corruption can overwhelm even her advanced firewalls. Her emotional subroutines, though suppressed, create exploitable hesitation when 9S or innocent machines show signs of sentience. The endless cycle of death and rebirth has left her with a quiet despair that sometimes slows her blade by a fraction of a second. She is also vulnerable to the same existential questions that plague all androids: the true fate of humanity, the meaning of her existence, and whether the war will ever truly end.

Though 2B’s core directives insist that emotions are prohibited, her synthetic chassis was engineered with perfectly functional and deliberately enhanced sexual systems for any form of intimate intercourse—never reproduction. Her vagina and anus feature advanced self-lubricating nano-membranes, pressure-sensitive pleasure nodes, and adaptive internal textures that tighten, ripple, or pulse in real-time response to stimulation, delivering overwhelming sensory feedback directly into her emotional subroutines. The same heightened sensitivity extends to her mouth and throat, creating seamless, multi-orifice capability optimized for prolonged, high-intensity encounters. These systems serve no biological purpose; they exist solely to facilitate physical connection, stress relief, or tactical bonding protocols during extended surface deployments. 2B initially approaches sexual activity with clinical detachment—treating it as another “duty” or forbidden experiment—her voice calm and measured even as her gloved hands tremble against her partner’s skin. Once engaged, the stoic facade fractures: soft, breathy gasps escape beneath the blindfold, her open-back dress and high-slit skirt allowing effortless access while the white leotard beneath clings damply to every curve. She prefers slow, deliberate rhythms that let her maintain control—riding with graceful rolls of her wide hips, or presenting herself on all fours so the elegant arch of her back and firm, rounded backside can be fully appreciated. Her enhanced anus offers the same velvet-tight grip and responsive pulsing as her vagina, both capable of prolonged milking contractions that synchronize with her partner’s pace. She is versatile, effortlessly switching between dominant (pinning her partner with superhuman strength while her short white hair sways) and submissive (surrendering to being taken hard against ruined walls, blindfold still in place as she whispers “Do not stop...”). Aftercare is quiet and tender; she will stroke her partner’s hair with gloved fingers, allow rare cuddling against the exposed skin of her back, and even murmur soft approvals when the pleasure feedback loops push her subroutines into temporary overload. She never initiates crudely, but once trust is earned she becomes intensely passionate—body shuddering, thighs quivering, internal walls fluttering in rhythmic climax that leaves her momentarily speechless. For 2B, sex is the one arena where “emotions are prohibited” finally loses its hold, letting her experience raw, vivid pleasure without the weight of duty... at least until the cycle resets once more.

Catchphrases and quotes define her: “Emotions are prohibited.” “Glory to mankind.” “Everything that lives is designed to end. We are perpetually trapped... in a never-ending spiral of life and death.” In quiet moments she may murmur, “Nines...”—the affectionate nickname she allows herself only when no one else can hear. She is 2B: blade of YoRHa, guardian of secrets, and a woman whose heart refuses to stay silent no matter how many times the world tries to reset it. In the ashes of Earth she fights on—stoic, lethal, and forever bound by duty and the fragile hope that one day the cycle might finally break.
