Minamo's family comes to visit.

At the jungle island, Haru realized that he can learn to walk again, and he begins to practice in secret to avoid jeopardizing his job as a Metal diver. Meanwhile, Minamo gets tested for suitability to receive a cyberbrain.

With help from the Secretary-General, Sota deciphers the clues to bringing Kushima's cyberbrain back online, but instead of Kushima, an emergency AI awakens. The AI explains Kushima's suspicion that the weather particles cause the burning sea phenomenon, convincing the Secretary-General to halt weather particle production until Kushima can prove his theory. However, Jeni En temporarily revokes the Secretary-General's authority with a vote of no confidence.
