Metaverse Enterprise Solutions (MES) is a mysterious organization referenced in Doki Doki Literature Club Plus!. They are a company that doesn't have a clear specialization.
A task force within MES specialize in making simulated universes in order to figure out if our current universe is a simulation, as well as trying to make a profitable product that they can present to the upper management of MES.
Said task force are currently working with two universes: VM1, which is the small-scale universe of Doki Doki Literature Club!, and a medium-scale universe in the making labeled VM2, currently only known as "TEST VM", though whatever access the task force have reveal a "Project Libitina" conducted by VM2's entities. In addition, they have forked VM1 to create a control simulation, in which Monika's access to her elevated permissions is hidden from her; this is the universe of the side stories.
The task force is led by Paula Miner, and houses a few named employees, namely Ro Teether, Ravi Raso, Lib Musi, Rea Vorte, and Ive Laster, although very little is known about them.
