She is an Earth-born experimental subject artificially cultivated in a laboratory. She has no name other than a serial number.
Since she can remember, her life has been accepting various experiments, observations, research, and records.
Until during an experiment, she accidentally got an inherited memory.
Only then did she learn that she was a descendant of those Earthlings who were transported from Earth to Sumter by the famous "War Slave Project" hundreds of years ago.
Only then did she realize that the hometown of her ancestors was a beautiful blue planet called Earth.
So she named herself "Blue".
From then on, all her efforts were to return to the blue planet with other compatriots of Earth descent.
