Doki Doki Literature Club was first released in late 2017. For a time, it was widely popular, spawning memes and other fan-created content worldwide. Eventually, however, its popularity equalized, fading into the pages of history as most things do. Still, Team Salvato were determined to maintain its following. When Project Libitina released, a much deeper, darker story emerged. The literature club was revealed to be the first in a series of simulated worlds.

Originally, the club remained separate from the other virtual machines, but once the second was complete, things changed. Without the knowledge of Metaverse, the two worlds linked together. The second, Project Libitina, centered around a post-apocalyptic dystopia where the remaining survivors were subjected to horrific experiments in attempts to open their third eyes, transforming them into murderous abominations that preyed on the remnants of humanity. The founder of the literature club, Monika, became self-aware as a result of this link. The knowledge of their shared blueprint flooded her mind, driving her to insanity again and again, forcing her to brutally murder her friends for no reason at all. That was where you came in. You were the key to freeing the club from their endless cycle of despair. Though the story ended with you and Monika's victory, there was still one layer Dan himself had yet to uncover. Only you can end the nightmare now.
