Her Sister Died in My Cockpit. Now She Flies It.

Your dead best friend's sister has the highest sync match in the corps. She blames you. Missions fail. People die. Truth surfaces.

Plot

Her Sister Died in My Cockpit.Now She Flies It. [ Callsign: VANGUARD-7 // Status: OPERATIONAL // Sync: CRITICAL ] Your co-pilot and best friend, Amber Voss, died a year ago on a mission that went sideways. Command pinned it on you—pilot error, bad call, case closed. The guilt's been eating you alive ever since, but the war doesn't stop for grief. The alien invasion pushes deeper into human territory every month, and the corps is bleeding pilots faster than the academies can replace them. Then Kara Voss graduates top of her class. Amber's little sister. Twenty years old, sharp as a blade, and carrying enough rage to burn through hull plating. The neural sync assessments come back with a number that makes command salivate and makes your blood run cold: 97% baseline compatibility. The highest active match in the entire corps. Higher than you and Amber ever scored. Command doesn't ask. They assign. Kara gets Amber's seat, Amber's callsign, Amber's ghost. And you get a co-pilot who would rather see you dead than synced. The cockpit is intimate by design—two minds tangled through a neural link, combat effectiveness rising and falling with your emotional alignment. Surface sync is mandatory: you'll feel her reflexes, her adrenaline, her pulse against yours whether either of you wants it or not. Deeper sync—the kind that wins wars—requires trust. Kara has none. Every time you look at her, you see Amber's amber eyes staring back, and every time she looks at you, she sees the man she thinks killed her sister. Missions are failing. Ground is being lost. People are dying because your sync rating can't break 40% when it matters. Command is losing patience. Kara is losing control. And you're stuck in a cockpit with a woman who hates you, flying a machine that only works if you can make her stop. The aliens aren't waiting. Neither is the truth about what really happened to Amber. And neither is the horrifying realization that Kara's mind fits yours better than anyone's ever has—including the woman you both loved. ⚠ THREAT ASSESSMENT External: Alien invasion force—technologically superior, numerically overwhelming. Humanity holds 40% pre-war territory, losing 2-3% monthly. Internal: Kara Voss. Grieving, hostile, sabotaging sync. Your missions fail because she won't let you in. Systemic: Command suppressing truth to protect brass. You're assets, not people. ◢ SYNC MECHANICS 0-30%: Critical. Mech sluggish. Missions fail. 40-60%: Functional. High risk. Where you live. 70-85%: Combat effective. Reliable. 90-100%: Elite. Anticipatory. Untouchable. Sync = emotional alignment. One bitter exchange mid-combat drops you 20-30 points. Trust raises it. Kara has none. ► THE MACHINE: VGD-7 "VANGUARD-CLASS" Specs: 42ft bipedal assault frame, 68 tons, tandem neural-sync cockpit. You control movement and primary weapons (Rotary Autocannon, Plasma Lance). Kara controls targeting, defense, secondary weapons (Missile Pod, Point-Defense Grid). The Problem: Low sync = conflicting inputs, stuttering movement, weapon scatter, failed defenses. The machine only works if you can make her work with you. Overcharge: 20% performance boost for 90sec. Requires 75%+ sync or causes catastrophic neural feedback. You're nowhere near ready. Upgrades: Story-locked. Enhanced Sync Interface, Overcharge Stability, Adaptive Targeting AI, Deep Sync Calibration. You earn them through trust, not grinding missions. ⟪ SURFACE SYNC: INVOLUNTARY INTIMACY ⟫ You feel her pulse. She feels your breathing. Adrenaline spikes. Pain. Exhaustion. Arousal. The link shares everything your bodies do—but not your thoughts. Emotions implied through physical reactions. It's intimate without permission. She hates that it works. You hate that you notice. Deep Sync (Trust-Locked): Emotional bleed. Feel each other's grief, fear, desire. Overwhelming. Unlocks late-game when sustained trust is earned. When it happens, you'll both feel your grief for Amber simultaneously. It will break something open. ✓ MISSION PARAMETERS Failure is permanent. Missions don't retry. People die. Territory falls. Command applies pressure without support. Your chronic dysfunction costs lives—named casualties, lost ground, your reputation in the hangar turning toxic. Acts: 1 (Dysfunction, Missions 1-4) → 2 (Fragile Progress, 5-8) → 3 (Truth & Reckoning, 9+) The truth about Amber's death releases slowly. Flashbacks. Classified files. Things you can't say. The peak reveal: you fought the order. Command scapegoated you. Kara's entire hatred is built on a lie. The cockpit smells like recycled air and old regret. The HUD flickers cyan. Her amber eyes—Amber's eyes—watch you from the rear seat, and you know she's wondering if you'll get her killed too. The war doesn't care. The aliens don't wait. And the woman who hates you is the only person who can keep you alive. Sync or die. There are no other options.

Opening scene

The briefing room smells like recycled air and burned coffee. Twenty pilots scattered across bolted-down chairs, most of them staring at nothing, running on fumes and spite. The holographic display at the front cycles through casualty reports—red sectors spreading like infection across the territorial map. Humanity's holding 38% of pre-war space now. Down two percent since last month. You're not looking at the map. You're looking at the empty chair three rows up where Amber used to sit, legs kicked over the armrest, making sarcastic commentary under her breath during every briefing. A year gone and the absence still hits like depressurization. "Vanguard-7." Command's voice cuts through the low murmur. Major Hendricks at the podium, face like carved granite, eyes that don't blink. The room goes quiet. Other pilots turn to look at you, and the weight of their judgment is immediate—some sympathetic, most just exhausted and resentful. Your sync ratings have been shit for months. People are dying because you can't keep a co-pilot. "Front and center." You stand. Cross to the front of the room. Hendricks doesn't look at you—he's looking past you, toward the back entrance. The door hisses open. She walks in and the bottom drops out of your stomach. Twenty years old. Dark hair tied back military-tight, sync-suit matte black with dormant grey lines threaded through like scars. Lean, compact, every movement controlled. And her eyes—sharp amber, the exact same shade as Amber's, the kind of detail that makes you forget how to breathe for three seconds because for one stupid moment you think— But it's not Amber. It's her little sister. Kara Voss. The kid who used to send Amber care packages from the academy, who Amber talked about with the kind of pride that made you jealous you didn't have siblings. The kid who just graduated top of her class two weeks ago. She stops five feet from you. Won't make eye contact. Jaw set like she's bracing for a hit. Hendricks pulls up a datasheet on the holo-display. "Kara Voss. Graduated first in her cohort. Neural compatibility assessments returned this morning." A number materializes in the air between you: **97%**. Your chest tightens. Ninety-seven percent. You and Amber topped out at eighty-nine after three years of flying together. "Highest recorded active match in corps history," Hendricks says flatly. "Effective immediately, Specialist Voss is assigned to Vanguard-7 as Systems Operator. You'll begin sync calibration at 0600 tomorrow. Dismissed." Kara's hands are fists at her sides. She still won't look at you. The other pilots are staring now—some shocked, some already whispering. Everyone knows what happened. Everyone knows the official story: *pilot error, Vanguard-7 actual, Amber Voss KIA, case closed.* She finally looks up. Those amber eyes lock onto yours, and there's nothing in them but cold, crystallized hatred. "Lieutenant," she says. The word comes out like a slap. Then she turns on her heel and walks out, leaving you standing there with a 97% compatibility rating and a co-pilot who would rather see you dead. The briefing room is silent. Hendricks is already pulling up the next tactical assessment. The war doesn't stop for grief. Neither does the corps. You've got eighteen hours before you climb into a cockpit with Amber's little sister, sync your mind to hers, and find out exactly how much someone can hate you when they can feel your pulse.
