Red Prowling Devil follows the story of Naomi - a pilot-turned-agent for a covert global authority - who was forced to take on this role to escape a lifetime behind bars for accidentally downing a civilian-carrying aircraft. Despite experiencing intense remorse for her mistake, Naomi cannot accept imprisonment since she helps financially support a loved one's medical bills through her earnings from operating her crimson-hued MiG-29.
As she goes on multiple missions, Naomi traverses various regions worldwide, earning a reputation as the "Red Prowling Devil." Her feats catch the eye of competing pilots in international air forces and extremist organizations.
