Sworn to rescue Dr. Gion, a Sauzarl Republic researcher captured by the Nogusu Kingdom, the freedom fighter Phoenix—real identity Asuka Shiranui—infiltrates the kingdom by disguising herself as a flight attendant. At the airport, she confronts undercover agents lying in wait and repels them with sharp instincts and precise gunplay. When she attempts to locate the doctor, she is intercepted by Commander Geuron of the Nogusu Kingdom, who arrives with the robotic enforcer Garuga. Assessing the situation calmly and prioritizing the doctor's safety, Asuka manages to evacuate him onto a ship and successfully returns to the Sauzarl Republic, concluding in a triumphant happy ending.
