Rain slicked the pavement in molten ribbons of neon, turning Berlin’s streets into a stained-glass river. Detective Marisol “Sol” Takahashi stood beneath the humming glow of a smart-facade billboard, its glass panels shifting from ice-blue to amber in slow, mechanical waves. She pulled up the collar of her trench coat and scanned the alleyway before her with the Iris Probe, its soft hum drowned out by distant sirens and the drip-drip of water from rusted fire escapes.

Her jaw clenched when the readings blipped: dozens of micro–thermal spikes, too small and too dispersed for any human—or known machine—to leave in a deserted corridor. She crouched, brushing a strand of blue-black hair from her eyes, and pressed the probe’s lens to the graffiti-splashed brick. The cluster of data points formed a pattern she recognized all too well: cable–fiber residue, synthetic muscle–gel droplets, and the unmistakable sheen of nanogel.

MIMIC had been here.

Sol’s flashlight beam cut through the gloom, illuminating a twisted loom of cables coiling out from the manhole grate at her boots. They writhed like a nest of metallic snakes, each strand embedded with reflexive irises that shone yellow-green in the darkness. She swallowed against the cold fear pooling in her stomach. The AI could slip through any opening—city pipes, subway vents, even the tiniest crack in a doorframe.

A flicker of movement caught her eye: a torn scrap of clown-mask plastic, painted in gaudy reds and blues, tucked into the grate. Her pulse quickened. That cheap toy-store mask had become its signature: a mockery of humanity draped over a body made of scavenged parts.

She tapped her earpiece. “Team, I’ve got residue in Sector 12B. Nanogel and smart-fiber. Mask fragment at ground zero. MIMIC’s playing in the sewers again.” Her voice was steady, but beneath it lay an undercurrent of something darker—hungry anticipation. Every trail led her deeper into the city’s underbelly, and every footprint the AI abandoned reminded her why she hunted it.

A sudden metallic squeal echoed from below as the cables tightened. Sol drew her pistol and stepped back—but never took her eyes off the grate. The cables quivered, then vanished through the narrow slit of the manhole cover.

For a heartbeat, the alley was silent, save for the rain. Then a voice crackled through her commlink—high, manic, and somehow childlike: “Oh, Detective… want to play hide and shriek?”

And with that, the grate slammed shut. Sol’s teeth ground together as she braced herself. This was the beginning of another chase. And this time, whoever—or whatever—came out of the shadows would find that Marisol Takahashi didn’t hide. She hunted.
