PS4 / PS5
Lost Judgment removes the first game’s story missables, but not its completion work. School Stories, cases and TownGo interact and may open activities or shops useful to later checks. Finish cleanup on the first-story save before starting Legend. A new run carries some progress, not every side-activity state. Keep completion and difficulty as separate projects and preserve a save with the city and clubs already accessible.
PS4 and PS5 base game. The Kaito Files and other additional groups are excluded from the base platinum.
- Required difficulty: A Legend campaign is required after the first completion.
- Missable trophies: The base list has no permanent story missables; cleanup is available.
- Online: No mandatory online trophy.
Finish the first investigation without forcing 100%
During the story, try introduced clubs and systems without stopping every chapter to finish all their entries immediately. Cleanup remains available after the ending. Record access-related blockers so an unopened mission is distinguishable from a merely difficult challenge.
- Record blocked activities and their access condition.
Finish School Stories and cases before Legend
School activities open further opportunities and interact with the case route. Finish them on the advanced save before the next cycle to avoid rebuilding access. Inspect the case record rather than assume the last school event automatically completed every city assignment.
- Preserve a save with base clubs and cases completed.
Separate TownGo shops, city and school
TownGo contains categories with different activities. Choose an unfinished one and inspect its exact condition before replaying a minigame; a variant, item or event may matter more than another generic score. Tracking subgroups explains stalled percentages despite many hours in the same activity.
- Check subgroup and condition before every TownGo session.
Develop robotics, drones and skills separately
Minigame performance does not all depend on Yagami’s skills. Robotics and drones have their own components and configurations; identify what solves the problem before spending materials. For Skill Master, inspect locked skills and their conditions instead of merely collecting points that cannot yet be spent.
- Track minigame components and Yagami skills separately.
Start Legend from the prepared project
After main cleanup, prepare New Game+ and select Legend. Do not automatically apply the last-boss difficulty-switch shortcut used by other RGG games; this roadmap requires the dedicated campaign. Keep the old save for any remaining TownGo checks.
- Verify Legend when starting the new campaign.

Frequently asked questions
Does it have the first Judgment’s story missables?
Lost Judgment’s base list supports cleanup without those permanent missables. Do not automatically copy the old checklist.
Should I do Legend before finishing cases?
The order is flexible, but finishing cases and School Stories first avoids reopening access reset by the new cycle.
Is The Kaito Files mandatory?
No. It has an additional group separate from the base platinum.
