Trivia[edit]
- All Afterglow Hall operations are named after notable classical music. See the respective operations' Trivia section and this Google Docs file for more information.
- Lingering Echoes is the first event with different main menu background images:
- Initially the background shows Czerny, Ebenholz, and Kreide playing Licht und Schatten on the stage with Hibiscus the Purifier watching from the auditorium and a vibrant orange overlay.
- From the second week, if the player had cleared all Afterglow Hall operations, the background changes to showing only Ebenholz on the stage with all spotlights but one focused on him turned off, and has a gloomy gray overlay.
