The neon-acid rain-soaked walls of New Detroit’s shadowy alleyways, streaked with the glow of fluorescent hues 🟡—mercenary K draws the lime-green straight blade from his waist. Even as a pursuit team from a Akihabara-affiliated corporation scans for heat signatures from ten meters away 🔍, who would have guessed that this very blade, labeled “non-metallic training blade,” is actually an invisible killing weapon worth a million credit bounty on the dark web?

The boundless acid mist eats away at all metallic tracking tags ☁️, leaving the solid, monolithic nitrided-ceramic blade perfectly shielded from thermal and metal scanners 🤖. The segmented polygonal grip fits snugly into the custom bone-shaped groove K has modified in his palm, with zero millimeter of misalignment 🤙. The slot along the blade’s spine can hold corrosion-inhibiting neurotoxins—or it can slip into the fiber-optic conduit of the old city’s security grid to pry open doors and unlock locks 🕸️. Only K knows that the core data chip the corporation spent three months hunting for is embedded right inside the hollow, multi-faceted cavity at the very end of the handle 🔋.

K runs his fingertip over the blindingly bright acid-yellow blade; just around the corner, the red dot from the surveillance camera has already lit up 🔴. He raises his hand, aligning the blade with the password lock on the ventilation duct—after all, who says a training blade can’t be used to take the head of a top-level executive? In a cybernetic metropolis, the most unassuming-looking toy often turns out to be the deadliest weapon 🗡️.
