Lacage is a character introduced in the original video animation sequel Gargantia on the Verdurous Planet: Far Beyond the Voyage. She is introduced as a former member of the Cugel fleet who transfers to the Gargantia fleet after the two fleets merge. On the Gargantia, she becomes the newest member of Amy's messenger team. However, it is later revealed that Lacage is a spy working for an unknown party. As part of her secret mission, she orders the construction of a combat machine that resembles Chamber, the Machine Caliber piloted by Ledo. Her background as a former member of Kugel's fleet suggests she carries allegiances that conflict with the peaceful life aboard the Gargantia. Her motivations are tied to the unknown party she serves, though the full extent of her objectives is not explicitly detailed in the OVA. Lacage's key relationship is with Amy and the messenger team, whom she initially works alongside before her true nature is exposed. Her development involves the gradual revelation of her duplicity, positioning her as an antagonist in the story. In terms of notable abilities, she demonstrates the capacity to orchestrate the procurement of advanced mecha technology, indicating she possesses resources and influence beyond that of a typical messenger. The limited information available about Lacage means that her personality and deeper character traits are only hinted at through her actions as a spy.
