Soundless Footsteps: The Raven’s Puzzle
Grey drizzle spatters down over Akihabara, soft neon colors blinking over the traffic. At a narrow desk in the Nekoma City Police Department’s rookie unit sits Kaito Shiraishi, tracker for odd crimes. He thumbs through a heap of puzzle-shaped beads found at last night’s crime scene—the robbery at the Poison Apple Café. Have you noticed how the oddest clues come wrapped in the plainest wrappings?
Detective Shiraishi is twenty-two. He’s tall, slow to trust, and prefers thinking two steps ahead but only speaks when alone or if he must. Still, there’s one soul he confides in: Hitomi Kurosawa, a sharp cosmopolitan forensics analyst whose jokes warm any cold trail. She nudges his arm.
“You’ll stare holes in those beads, Shiraishi. Spill it—what’ve we got?”
He mutters, “Robbery or diversion? Three tech drives gone, no cash. No sign of forced doors, but footprints vanish by the dining hall’s locked back window.” Hitomi’s grin widens. Detours always thrill her.
The pair heads to the Poison Apple Café for another look. There’s no one on the block—the rumor mill is working fast tonight. Under the cluttered counter, Kaito’s fingers loose four black feathers. “Stray crow, or a call-sign?” he murmurs. Hitomi snaps a shot, “They love attention, always do.”
Shadowy figures watch from a roof opposite. A red-eyed bird sits among them. The game is starting.
Back at HQ, it doesn’t come easy. Case files fill the board. Four similar heists dot the city this month—their only link: these odd feathers and the bead puzzles left at every scene. It keeps hitting him: why these puzzles? Did you ever get the sense someone’s baiting you on purpose?
Shiraishi digs deeper. He tracks rare birds in Akihabara’s market and skips lunch chasing puzzle shop owners who sold those odd beads. Half give him blank stares. One, a sly woman in a dark shawl, quietly warns: “Night’s not kind to those that dig.”
That evening, Hitomi traces one feather’s color sequence to a rare breed called the Night Raven, sold to private collectors. She jokes, “Maybe we need to watch the bird cages for suspects.” But to Kaito, something clicks. Whoever runs these robberies knows cameras and guards. But birds obey simpler codes than men.

Across the city, Riko Asada, Shiraishi’s childhood friend and a skilled lockpick, approaches him outside a tiny ramen shop. “Those odd puzzles—they’re ring codes,” she whispers, smoke drifting through nervous lips. “Only a few spots can buy all the shapes. Your crooks use pattern systems like old rigging—or game console teams.”
Armed with this tip, the team scours digital records. It turns out: all the small bead codes tie straight to The Raven Sisterhood, a crew known for outsmarting top banks and auction houses. The group’s leader? Once believed a myth, now a faded name resurfacing through black market talk—Tomoe ‘The Black Raven’ Izumi.
Night peels back the next layer. Tech drives begin popping up for sale on secret networks by sunrise, loads of bidders fighting to buy them. Kaito volunteers to pose as a buyer. The risk weighs on him, but his drive to help the other rookie officers pushes him through worry—can one mistake drag them all into this web?
He follows directions sent by a shadow network avatar named Karasu. The location: high atop an abandoned office block, tucked between neon-clad towers. Hidden figures slip through the stairwell. Every few steps, another puzzle dangles from door handles—each solved opens the next locked door.
What would you do, following signs made for you, with someone laughing just out of reach?
He enters a room dressed in blue light. Four masked thieves block the path—one steps close, a low, clear voice hissing, “You’ve passed my tests. What’s your wish, detective?”
Kaito keeps his tone cool. “I want the drives. And answers.” She hands out another black feather, another bead. Tomoe smiles. “Do you like games, Shiraishi?”

The scene tenses. The rookie team bursts through a back entrance. Tomoe signals; the thieves scatter, leaving Kaito holding the last piece—a feather, a bead, and a riddled note: ‘Find what’s hidden in the walls of what’s seen by none—the Raven never comes alone.’
Did the real game just unspool?
In the dark, alone, Kaito looks at the bead and the feather, then the walls of the barren office. What clue did Tomoe truly want him to see? Back at HQ, clues laid out across the table, lab light flickering on faced feathers. Is Tomoe close… or drawing him toward something bigger?
The arc hangs here. Tomoe has left a trail straight to her. Or has she led the team farther from her roost?

Did you ever wonder why a master thief would rather play games than run? What happens if, next time Kaito solves each riddle, someone close is in the trap?
The puzzle twists as dawn creeps in, feathers shadowing every exam light. If Riko’s warning is real, who in the city gets hit next?
Kaito stands by HQ windows, city silence humming outside. Hitomi walks in, handing him noodles and hope. “Don’t scare yourself into circles, Kaito. Some games never finish, but you don’t quit.” He barely smiles back, pockets the feather.

Credits slide, with Tomoe’s face glimmering above the rooftops, hinting that her real motives have yet to show. Who makes the rules, and who’s just moving pieces? The pause before the leap leaves Akihabara’s heart drumming.
