F.S., known alternatively as Fog Sweeper, commands the entire Dancouga Nova project from his position of significant authority within the Dragon's Hive base organization. His presence is initially shrouded; all communications flow exclusively through the team's direct commander, Tanaka, enforcing a strict chain of command and keeping the pilots unaware of his existence and role. This veil lifts during a party in episode 6, where F.S. directly addresses the Dancouga Nova pilots. He discloses the project's critical origin: their mecha is modeled after a legendary Super Robot that historically defended Earth from an inhuman threat, positioning Dancouga Nova as the legacy's continuation. This revelation provides the team profound context for their mission and technology. F.S. maintains his focus solely on the strategic oversight of the Dancouga Nova initiative, never engaging in direct field operations.
