The scent of disinfectant mingles with the neon blue glow as it surges into the shadowy back alleys of the underground black market🔞. I press the heel of my palm against the non-slip texture on this ice-blue, claw-shaped blade, my knuckles turning pale from the sheer force of my grip⚪️. It’s a 3D-printed training knife—unsharpened, to be sure—but I’ve secretly embedded a layer of nano-cutting filaments in the blood groove🔪, enough to slice through the encrypted alloy doors of corporate conglomerates🔓. The thermal imaging scan from a city-defense robotic dog sweeps across my side🤖, yet it only registers me as an ordinary PLA plastic figurine; no one would ever suspect a pale-blue plastic blade of being a deadly weapon💨.

The conglomerate has harvested the neural imprints of twenty-three homeless residents from the Lower District and sold them to the elite as consumables for cybernetic augmentations—I’m here to set things right⚖️. One by one, the corridor lights flicker on, emitting a blinding red warning beacon🚨. I sidestep the patrol drone’s searchlight💨, then swing the knife at the encrypted door lock. The nano-filaments effortlessly cut through the alloy, and the icy-blue blade reflects the alarm’s red light, which dances across the wall like a crouching beast👹. In the distance, the rumble of tracks rolling over the ground grows steadily closer. I fix my gaze on the pulsating blue light of the server behind the door, while the ring at the hilt of the blade securely grips my wrist—this unassuming blue blade is about to carve out a lifeline for the Lower District today🌌✨.
