Amy Locke is a soldier serving in the United Nations Spacy military forces during the events of 2092. She holds the rank of 2nd Lieutenant and serves in the elite Faerie Squadron, led by ace pilot Sylvie Gena. Within the squadron, Amy flies a Valkyrie II variable fighter as one of Sylvie Gena's primary pilots. Her pink helmet serves as her visual identifier during operations.

During combat missions, Amy displays a lighthearted demeanor, frequently trading jokes and quips with fellow squadron members Saori and Nastasha, even amidst active battle. This behavior lightens tense situations. Despite this casual dynamic, the squadron achieves significant combat results under Sylvie's leadership, demonstrating operational effectiveness. The trio's personalities and functional roles echo those of bridge operation crews from earlier conflicts, though their primary duty involves piloting variable fighters, not capital ship operations.
