Cetus

Enjoys floating belly-up on the sea surface to bask in the sun. Sometimes, the ocean current would take Cetus across an incredibly long distance after it has been sun bathing for too long, and it takes a lot of effort for it to swim back.

Cetus greatly enjoyed pointing ships in the direction of the coast, but such opportunities are now very rare, which often gives it depression. It resorted to sunbathing to handle this problem until it recently discovered some human vessels could possibly still exist in high latitude regions.

Originally a bionic machine customized by a marine animal research center in the Golden Age for in-depth study of dolphin behaviors, Cetus was accidentally left forgotten in the sea due to changes in the center's staffing and project funding.

Cetus was not equipped with many weapons, as it was originally intended for scientific research purposes. In contrast, it had outstanding emotion simulating programs, which, in some aspects, were too good—some researchers at that time often had the false impression that Cetus really developed emotions.

As time went by, Cetus' peers had all vanished, leaving behind only Cetus with an aging and damaged body. It was calmly awaiting its ending when its sensors detected Lamia. Cetus' memory shell and emotion simulating programs were unable to understand the modifications it underwent, but the result is evident: it can now roam the ocean in a completely new form. Right now, it only wants to stay with Lamia though.
