Complete Judgment Yagami Detective Agency cases, including The Twisted Professor, The Mystery Writer's Stratagem, and Revenge of the Keihin Gang.

Walkthrough
  1. 1
    Access the bulletin board in your office to find available Side Cases.
  2. 2
    Select and accept a case to begin.
  3. 3
    Follow the on-screen prompts and objectives to complete each case.
Tips
  • Some cases require a specific Reputation Level (e.g., Level 5 for "The Twisted Groper", Level 15 for "The Twisted Judge", Level 20 for "Another Mystery Event!", Level 30 for "A Final Event", Level 50 for "A Golden Mouse").
  • Certain cases are unlocked after completing others (e.g., "The Twisted Groper" requires "The Twisted Professor", "Another Mystery Event!" requires "The Mystery Writer's Stratagem", "A Final Event" requires "Another Mystery Event!").
  • "A Golden Mouse" requires defeating all four Keihin Gang leaders in one session and witnessing "???" events (Side Case markers with Keihin Gang encounters).
  • Pay attention to specific locations mentioned, such as M Side Cafe, La Marche, Batting Center, Hotel District (Top of Ocean), Café Mijore, Poppo on Showa St., and Stardust rooftop.
  • Some cases involve unique mechanics like using the Drone, Active Search mode, or tailing an NPC (non-player character — anyone the game controls, not you).
  • Be prepared for combat, as many cases conclude with a fight, some of which can be difficult.
