Secretary of Foreign Affairs: Tsume Dragonis
Secretary of Defense: Leona Dragoon-II
Secretary of Internal Affairs: Kithanrya Swordsbane
While Firefury wields supreme executive power in the Shogunate government, she seldom exercises it outside of particularly time-critical or international matters; preferring to leave the bulk of the routine acts of government to locally elected representative councils and a national assembly headed by the Secretary of Internal Affairs.
The Shogunate government's diplomatic arm, referred to as the Diplomatic Corps (and often mockingly shortened to "DipCorps") handles all diplomatic functions under the jurisdiction of the Secretary of Foreign Affairs. The Corps staff includes translators, ambassadors, and anything else that pertains to international diplomacy.
While Firefury can order the deployment of military resources, the actual command is generally left to the Secretary of Defense. This includes the Shogunate's space combat fleets, aerospace forces, naval assets and ground troops. Given the generally pacifistic nature of the nation, most military deployments are in conjunction with the Triumvirate of Yut Combined Services.
