How to unlock Psyche in Duet Night Abyss
Here is how you can unlock Psyche in Duet Night Abyss:
Step 1: Progress through the story
Unlock the Immersive Theater mode by completing the early game story missions. This mode becomes available once you’ve finished the tutorial sections.
Step 2: Enter the Immersive Theater mode
Open the Immersive Theater from the event menu. Psyche is featured here for 28 days from launch, making her the first character you can target directly.
Step 3: Complete Immersive Theater stages
Play through the event stages to earn Psyche Secret Letters and Letters for her signature weapon.
You can obtain up to 65 Psyche Secret Letters total through consistent stage completions.
Step 4: Use earned Letters to unlock Psyche
After earning enough Secret Letters, exchange them in the character menu to unlock Psyche. Her full unlock requires the total reward threshold from the event.
Step 5: Continue farming in Nocturnal Echoes (after 28 days)
Once Psyche’s Immersive Theater period ends, her Secret Letters will move to the Nocturnal Echoes weekly boss mode.
She will replace one of the current reward characters—Tabethe, Truffle, Filbert, Yale, or Rhythm.
Step 6: Maintain progress through daily and weekly runs
Keep clearing Nocturnal Echoes once Psyche joins its pool to continue earning her Letters or those for future new characters.
Tips for faster progress
- Focus exclusively on Psyche’s Letter instead of dividing Clues among multiple characters.
- Participate in limited events whenever available—they often provide bonus Clues or direct shards.
- Always complete your daily Commissions to maintain a steady flow of Letters.
- Use your highest difficulty Covert Commissions for better shard drops.

To unlock Psyche in Duet Night Abyss, finish the main story prologue, collect Secret Letter Clues, exchange them for Psyche’s Letter, and repeatedly complete Covert Commissions until you’ve gathered 30 Thoughts.
