Giselle Collette is Fam's best friend and navigator in the vanship's back seat. Compared to the reckless Fam, she is introverted. Giselle collects and stores various battleship- and military-related data and covers for Fam in those aspects. As the eldest daughter of the Sky Pirates chief, Atamora, Giselle can easily handle housework such as cooking and cleaning while taking care of her brothers and sisters.
