Gannet serves as a supporting character within the narrative. Her visual design closely resembles Haman Karn from the Gundam franchise. After the main characters encounter a UFO, Gannet joins forces with them and its occupants. She accompanies the group on a journey to a space pirate colony and participates in their subsequent mission to Earth, aiming to confront the robotic uprising instigated by the Eterna supercomputer. Gannet possesses a fiery temperament that contrasts with other characters. She contributes actively to the group's investigation of Eterna's actions during their time on Earth. Her involvement occurs primarily in the latter segments of the series.
