The Laplace Mail is an important element in Devil Survivor. The Laplace Mail is a COMP e-mail that gets sent exclusively to the protagonist and his party every morning of the Lockdown. The sender of the Laplace Mail is only identified as "The Observer". The mail holds predictions for what will happen on the day it arrives, which always come true. However, the party makes it a goal to prevent the Laplace Mail's predictions from coming true.
The Laplace Mail is apparently a fully automated system, which would explain why it begins to glitch over time (symptoms being the distortion and incompleteness of the mails). It becomes progressively more difficult for the Laplace Mail to properly predict events due to the constant thwarting by the protagonist's party. It suffers from a complete breakdown following the delivery of its last e-mail on the 6th day, in which it explicitly names the original party as among the dead before it self-terminates, listing the cause as "too many invalid parameters."

The Laplace Mail and the Death Clock are believed to use what appears to be the same algorithym.

TriviaEdit

  • The Laplace Mail is named for Laplace's demon, a hypothetical demon created by a French physicist. Laplace's Demon knows everything about the universe at a particular moment, meant to show that all events are predetermined by the past.
  • The Laplace Mail makes two mistakes, changing characters' last names. On Day 5, it calls Keisuke Takagi "Keisuke Takashiro", and on Day 6, it calls Yuzu Tanikawa "Yuzu Hasegawa", both names similar to the original. This could be attributed to the Laplace Mail breaking over time.
