- Acclaimed Flop: While the game was received well alongside Persona 5: Dancing in Starlight in Japan, both of them had the weakest sales in the entire series (they even disappeared from the charts one week after their debut), making them the worst selling games in the franchise.
- Dummied Out: Placeholder images in the game imply that Koromaru was meant to be playable. Adding to this is that there are unused voice clips of everyone except Elizabeth, Theodore, Labrys and Margaret cheering him on. His only appearance in-game is during the music video for Voice (Atlus Tsuchiya Remix).
- Talking to Himself: There are multiple cases of Mitsuru and Elizabeth having social conversations together, both being voiced by Tara Platt.
