Niji Protocol description

Niji Protocol casts you into a neon-drenched battle of wits where glamour hides ancient greed. The Demon Aristocracy moves behind velvet ropes, masquerading as human elites while liquidating humanity’s history. From the Torch of Lady Liberty to the Imperial Seal of Japan, priceless artifacts vanish to decorate their hidden underworlds. The Niji Protocol is active, and it’s your job to stop these thieves in their tracks.

Gameplay blends retro detective work with puzzle-driven deduction. As a field agent, you chase a demon thief across a global map, gathering clues to predict their next destination and uncover their true identity. You visit 30 neon-soaked cities, from rainy Neo-Tokyo avenues to the frostbitten skyline of Toronto. Investigate famous landmarks and interview local witnesses—from snobbish hotel concierges to weary street vendors. Decipher clues about appearances, currencies, and flight paths to guide your investigation.

The core logic puzzle demands speed and accuracy. Build a case with The Grimoire by inputting traits and habits gathered from witnesses to narrow 24 High-Profile Demon Suspects. Use The Seal of Banishment to issue the warrant only when you have positively identified the target—the final confrontation hinges on this paperwork. When you corner the suspect at their last location, you banish them if your identification is correct; a wrong guess lets them escape with the loot.

Key features:

  • Procedural cases mean no two investigations are the same—the suspect, artifacts, routes, and clues are randomized for endless replayability.
  • Neon-noir visuals blend 1980s retro anime styling with high-contrast, dreamlike color palettes.
  • Educational trivia leverages real-world geography, history, and culture to pinpoint where the suspect fled.
  • Rank progression from Rookie to Ace detective unlocks harder cases and elite clearances.
  • Original soundtrack designed for the twilight of the 20th century enhances the mood as you chase time.

Time is running. The collection nears completion, and the fate of history rests on your ability to identify, warrant, and banish the right demon before they vanish with the loot.
