Gargantia on the Verdurous Planet (2013)

Striker says that it was following Kugel's instructions after his death and eventually reached the conclusion that to ensure stability to the fleet, it was necessary for the humans to view Striker as their god. Both Ledo and Chamber reject Striker's offer to join its side and decide to destroy it. Unable to defeat Striker in their current condition, Ledo decides to merge his nervous system with Chamber's interface to increase its capabilities at the cost of his life. However, Amy appears soon after to tell Ledo that he does not need to fight alone. Meanwhile at the Gargantia, Ridget uses the key she received from the Fleet's former commander to activate an ancient mass driver stored inside the main ship, and uses it to bombard the enemy fleet. Pinion evacuates his crew aboard the salvage vessel, and intends to destroy both the recovered relics and Striker's followers attacking his ship, but is saved at the last second by Lukkage. Striker then decides to attack the Gargantia but Ledo and Chamber pursue it. Despite being willing to sacrifice his life to protect his friends, Ledo reveals that his true desire is to survive the battle and return to live at the Gargantia with Amy. Chamber then relieves Ledo from duty and ejects him to safety before destroying Striker in a suicide attack. Some time later, Lukkage and many survivors of Kugel's fleet join the Gargantia. Ledo has become an experienced salvager who seeks to understand the whalesquid, and is able to enter their territory without provoking them. He hopes that humans will eventually learn the means to properly communicate with the creatures. He also seems to be in a relationship with Amy. In the ocean, a whalesquid larva is attached to Chamber.
