Monster King Orochi
The Monster Association consists of around 500 monsters, about 30 of which are disaster level Demon or Dragon. The Boss is the Monster King, Orochi, although the organization is actually overseen by the Military Advisor ,Gyoro Gyoro (who is actually a puppet of Psykos, the creator of Orochi). Directly below them in ranks are the Executives, also known as Cadres, who are specially promoted by Gyoro Gyoro. Orochi wants to find a worthy sacrifice for his ressurection as a god.
