@anon92, no the Five Great Families are Slash Dog's plot, the organization you said are indeed form from the the exiled or outcasted members, hence why they form their organization, they wanted to gather the Four Fiends to counter the Four Gods of the Five Great Families. Slash Dog (reboot) already introduced the Himejima (Suou and Suzaku) and Kushihashi (Seiryuu) and more would be coming soon from there. So the Five Great Families are part of the Slash Dog's plot.
