A 16-year-old Galactic Alliance ensign. Trained as a soldier since birth, Ledo finds himself shipwrecked on Earth following a failed attempt by the army to destroy the Hideauze's home planet. As he interacts with his new surroundings and gets used to the crew of the Gargantia, Ledo is exposed to some concepts of human society long forgotten by his civilization (or at least obscured from its soldiery) due to its permanent state of total war against the Hideauze, like entertainment, cooperation and tolerance. Ledo gradually grows attached to his new friends on Gargantia.
