Meyer & Hilton is a powerful company that used Contractors as experimental weapons for the UK during the war with Argentina. They inbred Contractors, hoping to mass-produce them; attempted to mix different powers though hybridization and eugenics; and even experimented with forcibly entering normal people into contracts via brain surgery. Luc and Kenneth are members of this organisation. Kōzō Tahara used to work for when the Hell's Gate first appeared, but he quit because he did not want them testing on his daughter.
