The game contains several references to the 1990's American TV show Twin Peaks. These references include:

• A rundown hostess club called Log Lady, which references the character Margaret Lanterman, nicknamed the Log Lady by the residents of Twin Peaks.
• The Black Lodge bar, which is a reference to the mysterious Black Lodge that the characters search for near the end of Season 2 of Twin Peaks.
• A restaurant called LL Diner, which is a reference to the Railroad Diner (commonly known as the Double R Diner and labeled as the RR Diner) in the town of Twin Peaks. The restaurant in 428 swaps the R's for L's, as a nod to the Japanese language sharing the same phoneme for both letters.
• The character of Leland Palmer, introduced at the LL Diner, which is a reference to the Twin Peaks character of the same name. While wildly different characters, both of them share the same trait of Spoiler:being secret antagonists puppeteered by the main villains of the story, Alphard and BOB respectively.
