Maaie serves as a fighter pilot aboard the Emaan trading vessel Glomar, operating in tandem with her twin sister Lieea as part of the crew's combat forces. She pilots her personalized "Drifant-type" ship, designated "M.Lover Maaie," primarily engaging in aerial combat to defend the Glomar. This defense is critical against attacks by the militaristic Chilam forces during traversals through fragmented, war-torn dimensional landscapes.

Maaie and Lieea function as a closely coordinated unit, their combat activities consistently depicted together. They represent the Glomar's only dedicated fighter pilots besides the protagonist Kei Katsuragi, significantly contributing to the vessel's defensive capabilities.

Documented materials define Maaie solely through her operational role as a pilot and her familial relationship with Lieea within the Glomar's crew dynamic. The available narrative, including the "Memorial" compilations focusing on characters like Mome, Kei, Mimsy, and Athena, alongside the absence of supplementary materials such as novelizations or drama albums, provides no details on Maaie's specific background, character development, expanded storylines, or personal history beyond this core function.
