==Trivia==
*Vicious Labyrinth's internal name is "yugamu" (歪む), which is Japanese for "twist/distort/corrupt".
*Grievous Lady represents the game's first anomaly song, and was the first to have a Level 10 chart (rerated to 11 in v3.0) on any difficulty.
*This song pack consists solely of Conflict-side songs.
**Hikari & Tairitsu (Reunion)'s skill will still apply to all songs using the yugamu background, and change them to the rei background.
