R.R.D.

M.I.D.S is a group of scientists belonging to Kaiba Corporation.

Its is known that the leading developers within the Momentum Investigation and Development Section were actually the parents belonging to Yusei Fudo.

Prior to the pilot of Yugioh 5D's, this group were the one who came across the development of the Enerdy tecnology. As their research also had resulted in the construction of the Old Momentum. Therefore they had the task of activating it, however it is known that the systems's control were quite imperfect at the time.

Because of that imperfectivity the Old Momentum began to work out of control, as began emitting a negative energy. Ultimately leading to the disaster known as the Zero Reverse Effect, which caused Domino City to be splitten. Thus this accidental disaster also claimed the lives of Yusei's parents.

After that, according to what Mina told to the journalist Carly Nagisa, M.I.D.S went to the task of concealing the truth of this incident to the world. They had manipulated all information so that the people believed that instead it was all caused by a natural disaster, as it sounded more convincing.

Though Carly then knew the truth ready to write about it she's warned not to. As M.I.D.S has completely convinced people so much that it is unknown as if someone would actually believe her. To make matters worse nobody has dared to confront them due to the fear of being send off to Satellite.
