There is an apartment complex in front of an alleyway located a short distance from Toro's hotel room. If you visit this location in the evening, you can see in one of the second floor windows (the cursor pointing at it in the attached screenshot) what appears to be a giant ghostly face covering the whole window. This phenomenon seems to be addressed in a dialogue the player can have with Toro either directly in front of the building or heading up the stairs in the alleyway leading to it:


The discovery of this secret shortly after the game's release caused speculation among Japanese players as to if it was an intentional Easter egg, or a case of poor lighting inside the building, but the answer remains unknown.
