Rector commands the Galaxy Patrol Cosmo Police Space Station Office, holding a position of authority within the organization. His primary responsibility involves issuing operational directives and assigning missions to protagonist Justy Kaizard. These assignments include critical operations, such as directing Justy to transport Astaris Vega during a hostage crisis involving criminal espers who hijacked a civilian shuttle.

His role remains consistently professional and administrative throughout both the manga and its OVA adaptation, focused exclusively on his command duties within the Cosmo Police hierarchy. The OVA maintains his depiction as a mission commander without personal details. Rector's presence is confined to these occupational responsibilities, with no exploration of his personal background, origins, relationships, beliefs, or character development across official media.
