Ridget served as the aid to Fairlock, captain of the Gargantia. However, after his death in Episode 8, she is named as his successor and takes full command of the fleet. Ridget is calm, diligent, logical, and holds a strong sense of responsibility. However, she is also known for being serious and stiff, so many keep their distance. She also has a laid back side seen in episode five when she strips off her diving suit to reveal her swimsuit.

While fighting an intense inter-galactic war, a mecha pilot was accidentally warped into a space-time neither he nor the computer of his mecha could recognize. After waking up from a six-month hibernation, he found himself trapped on a planet, with human residents speaking in an unknown language, using inferior technologies, and -- most shocking to him -- breathing natural air.
