Shiki resolves to defeat Shura after Hermit discovers the reports of machine rebellions outside Foresta were falsified to justify the robot extermination. Laguna brings the crew to the desert planet Sandra to enlist the help of Oasis, a rebel organization that opposes Nero, revealing himself to be a former member who abandoned the group. The crew learns from Oasis that Shura plans to control the robots through the All-Link System, a network on the planet Nero 66 that only functions when the planets are submerged by the Aoi Cosmos's ocean during high tide. Oasis's leader, Goodwin, initially rejects the crew's help out of hostility towards Laguna, but reconsiders when the crew demonstrates their greatly improved power and skill against a sudden imperial raid.
