- For other music featured in the game, see Music.
Attendant Background Music (BGM) is a song unique to the player's current attendant sword that replaces the regular Citadel theme when toggled.
- When the Attendant BGM is obtained, the Citadel and Activity BGM will change to the Attendant BGM when the specific sword is set as the Attendant Sword.
- It is possible to toggle between the default Citadel BGM and the Attendant BGM in the Settings.
- You can view and hear the obtained Attendant Sword BGM in the Sword Library.
The maximum amount of instruments you can keep is 999, and all obtained instruments and Attendant BGM will be kept even after the instrument event ends.
