Miracle Matter is the leader of Cleaning Team, but not one of sephiroth. Their role is to clean up and wash departments so that they don't cause more panic for other employees. They're immune(×0.0) to every damage, so even team Rabbit can't graze the grass of them.
They are also an "abnormality group that wants other employees to work in a clean environment."
