Elza from the Sea
The 999 was searched by Brittenian soldiers when it landed on the God Given planet. Maetel and Tetsuro met Nasuka, one of the soldiers who was sleeping on the job. Tetsuro later found Nasuka, who was taking a boat to Honiara Island, where the planet elder resided. The two entered a cave and found the elder, who informed them that the planet was about to enter an ice age, but this would also waken the sea-dwelling Suraoids. On their journey home, Tetsuro and Nasuka found his lover Elza, a Suraoid injured in an underwater attack. They were discovered by fellow Brittenian soldiers, and the captain arrested Tetsuro and ordered the execution of Nasuka and Elza. Maetel appeared and drove the troops away. Nasuka and Elza left to find a place to live their lives in peace.
