We call ourselves MD-5, and our mission is to... TAKE DOWN THE EVIL CONGLOMERATE TAAAAAAASCOOOOOOOORP!
MD-5 are the main protagonists of Meta Runner. They are a underground group that rebels TAS Corp.. Their headquarters is in a hidden room at the back of the Ramen Restaurant.
MD-5 was founded about a year before the events of the show to retaliate against TAS Corp. for the lives they destroyed. Despite their best efforts, any attempts to gather information and expose them were thwarted due to the company's high level of security, at least for now.
