The investigation commences with Yagami acquiring a specialized detector device, immediately deployed to locate a surveillance bug concealed in Public Prosecutor Ogami’s vehicle. This critical tool becomes indispensable for identifying the rogue detective’s activities.

Following the initial discovery, activate your smartphone application and search using the keyword “noise” to detect additional instances of unauthorized surveillance. This digital-physical investigative combination proves essential for case progression.

Pro tip: Regularly check your phone between main story missions, as new noise reports often appear that aren’t immediately obvious through normal gameplay.

The Wandering Bug

Near Yokohama 99’s headquarters, community chat groups report electronic disturbances. The source is Momoyama, whose handbag contains a covert tracking device planted by her manager.

Deploy your detector to identify the interference signature, then approach Momoyama directly. After gathering information, visit her nearby club establishment and confront the manager. Resolution occurs after his explanation, unlocking subsequent cases.

Grasping Attention

Another surveillance device activates at a local arcade. Inside, identify a manipulated prize within a claw machine using your detection equipment.

Insert coins and operate the machine until securing the compromised prize. The investigation reveals arcade manager Toru implanted the device to monitor a high school student obsessed with winning the specific plush toy. Defeat him combat to extract additional investigative clues.

Before The Torch Burns Out

Current noise reports direct attention skyward. Journey to Central Street and scan upward to identify an aerial drone. Activate Yagami’s observation mode to trace the operator’s location.

Using your detector, locate the high-tech voyeur in an Ohama Street adjacent alley. Advanced strategy: Observation mode works best when combined with detector readings—use both simultaneously for fastest target acquisition.

The Eavesdropping Wallet

This case introduces more sophisticated surveillance methods. The target has implanted listening devices in personal items carried by multiple victims throughout the city.

Common mistake: Players often focus on single targets when multiple may be compromised. Systematically scan all NPCs in the affected area to ensure complete device removal.

Seiryo High In Danger

The investigation escalates to involve educational institutions. Students at Seiryo High report suspicious activities and potential privacy violations requiring immediate investigation.

Optimization tip: Before tackling school-related cases, ensure Yagami’s combat skills are upgraded, as these missions often involve challenging confrontations.

From The Pit Of Despair

The corrupt detective’s methods become increasingly desperate and dangerous. This case takes Yagami to locations with heightened security risks and more aggressive opponents.

Time estimate: Allow 15-20 minutes for this investigation, as it involves multiple location transitions and evidence collection phases.

The Secret Ingredient

Culinary establishments become surveillance targets. Restaurant staff report electronic anomalies affecting kitchen equipment and customer areas.

Practical strategy: When investigating food service locations, check both public dining spaces and restricted staff areas, as bugs are often placed in both.

The Final Night Flight

The conclusive confrontation with the rogue detective unfolds across Yokohama’s nightscape. This mission integrates all previously learned investigative techniques.

Advanced preparation: Before starting the final case, ensure you have completed all available side content and upgrades, as the difficulty spike is significant.

Mastering the detector device requires understanding its range limitations and interference patterns. Optimal usage involves slow, systematic scanning rather than rapid movements. The device emits distinct audio cues when approaching hidden surveillance equipment—learn to differentiate these sounds for efficient detection.

Observation mode serves multiple investigative purposes beyond tracking drone operators. Use it to identify suspicious behavior patterns, locate hidden passages, and spot environmental clues others might miss.

Combat preparation proves crucial throughout these cases. The corrupt detective employs aggressive enforcers who will physically confront Yagami. Ensure your combat styles are adequately developed and consider our Class Guide for strategic approaches to different enemy types.

Between missions, consistently monitor your phone’s community apps for new leads. Many players miss time-sensitive reports that appear only briefly between main case progressions.

For comprehensive gameplay enhancement, consult our Complete Guide for additional investigative techniques and Weapons Unlock strategies that can be adapted to Lost Judgment’s combat system.

Remember that investigative efficiency directly impacts case resolution time. Developing systematic scanning patterns and learning to interpret detector feedback will significantly improve your performance across all Dastardly Detective missions.
