The M.E. is used to erase the memories of normal people who come in to contact with Contractors during the period when all information about Contractors was kept secret. The M.E. is also able to extract and implant memories from people, and it can even extract memories from recently deceased people. This is referred to as the M.E. Squeezer by Repnin. The M.E. uses a network system similar to the Doll Network and can store the memories of individuals that it has been used on and the events witnessed by the Doll Network.
