Maaie serves as a pilot aboard the merchant vessel Glomar, operating the red Drifand-class spacecraft designated "M.Lover." As part of the nomadic Emaan trading group, her cultural background reflects their customs and traditions. She and her twin sister Lieea, piloting a separate craft, function as one of the Glomar's primary defensive units before Kei Katsuragi's arrival, tasked with protecting the ship during combat.

Maaie possesses light blue hair and blue eyes. Her narrative presence remains consistent throughout the series, focused solely on her duties as a pilot without individual story arcs, personal conflicts, or transformative experiences. Her professional role and twin sisterhood define her established connections.
