Step-by-step unlock guide

Verify you have necessary prerequisites (NG+ status, charm slots, etc.)
Reach the trophy trigger location/chapter
Equip recommended charm loadout for the trigger condition
Execute trigger action (boss defeat, item pickup, route completion)
Verify trophy unlock via in-game notification
Save immediately after trophy pops to preserve progress

Common mistakes to avoid

Saving before trigger but losing progress on death
Selling required items prematurely
Triggering wrong route variant (especially for ending trophies)
Missing the optional boss / collectible window

NG+ shortcut method

New Game Plus enables free chapter selection. Use this to farm trophies you missed without replaying the entire game. Infinite Magnum (NG+ unlock) trivializes many boss-required trophies.

Trophy chains

This trophy may chain with related trophies for efficient completion. Plan trophy hunts to maximize per-playthrough progress toward Platinum.
