| Signature Move | Lunatic Voice | |
Signature Move: Lunatic Voice
Lunatic Voice deals Wind magic damage to all enemies with seven hits. It also has a chance to inflict Sleep and Silence for two turns, potentially preventing enemies from acting or casting spells.
Tips for Using Siren
- Disable dangerous enemies: Lunatic Voice can inflict Sleep and Silence across the enemy group. Use it when preventing enemies from acting or casting spells would give your party an advantage.
- Take advantage of her many attacks: In addition to having Wind and Water-based attacks, Siren can only inflict status ailments. It's not always a guarantee that those attacks will be chosen during her summon, but it gives you a wider range of the type of enemies you can use her against.
How to Get Siren
[1] Progress through the Main Story.
Siren is the only Esper that is not missable and is obtainable through the main story. Proceed with the main story objectives until you reach Grandport Harbor and receive the objective to visit Siren.

Go to Siren's Tower. It is north of Grandport Harbor.
Climb up the tower to the top and meet Siren.
[3] Defeat Siren.
Siren is at Level 11 during the fight. She resists both Wind and Water attacks but is weak to Lightning. As she is the lone fighter on the field, when you run her stagger meter to zero, it will automatically activate resonance. Use that to your advantage.
Be careful of her devastating move, Allure! It will Charm the whole party.
