OVA 1: Abandoned Fleet

The Gargantia comes across an abandoned, derelict fleet and Ledo joins a small group sent there to investigate it while looking for treasures. Amy and her friends sneak aboard their ship and end up joining the search party. Upon finding an old picture, Ridget realizes that the fleet used to be where her childhood friend Storia lives after she left the Gargantia seven years ago with her boyfriend Ritona. Upon checking up the main ship, Pinion concludes that the fleet's inhabitants were forced to abandon it after the main engine was broken beyond repair and the group returns to the Gargantia empty handed, except for Ridget who kept the picture for herself.
