“The Occult Detective delivers a genuine revelation – its exquisite art style perfectly complements the refined Shin Honkaku deduction system, while the supernatural narrative adds an electrifying twist. This is detective gaming at its most polished.”

“The team's innovative use of AI in shaping character personalities has genuinely infused the characters with a sense of vividness. Both the "iceberg-style narrative" and "deep deduction" deliver a refreshing and engaging experience.”

About This Game

English Localization in Progress!!! 

We are excited to share that the English version of The Occult Detective is officially under development!

Please stay tuned for more updates.

The Occult Detective is a narrative-driven game blending rigorous logic of classic detective fiction with unsettling supernatural mysteries. You will be discovering vital clues in every case, diving into unscripted interrogations and uncovering truths that break minds.

Play as a rookie investigator for the A.I.B. (Agency of Investigating the Bizarre). Your job? To secure unknown artifacts, suppress forbidden powers, and solve murders that defy the laws of physics.

KEY FEATURES

🗣️ Unscripted & AI-Driven Interrogations

Tired of linear games where you just click until you find the "one true evidence"? We break the rigid structure by integrating large language models (LLMs) to power our NPC dialogue.

  • Investigate at your own pace: Collect evidence and connect clues freely.

  • Talk Directly to Suspects: Question every suspect in a truly unscripted manner using natural language (text input).

  • Logic vs. Lie: Your goal is to use physical evidence to push their personalized defenses, not just click through pre-written dialogue trees. You lead the interrogation.

👁️ Even Anomalies Leave Traces

Welcome to this world touched by mysterious secrets. Here, shadow organizations safeguard relics of lost gods, while desperate souls in the city’s underbelly whisper of forbidden rituals. As an investigator, you must untangle a web of mysteries where the suspects may not be entirely human, but the motive is always grounded in cold, hard logic.

🔍 Deduction Above All

We focus on "New Orthodox Mystery" where deduction is paramount. Even in a world of supernatural abilities, the rules of deduction still apply. You must reconstruct the crime scene, understand the specific "rules" of the artifacts involved, and expose the killer through pure reasoning.

📚 A Sprawling 400k-Word Saga

Prepare for a deep dive. With over 400,000 words of intricate storytelling, The Occult Detective offers a dense visual novel experience filled with hidden secrets and unforgettable characters. Every conversation matters. Every text log counts.

It's time to see the world for what it truly is. Your investigation begins NOW.
