About 30 years ago, a ship crashed on a goverment research island deep in the Atlantic Ocean. One of the surviving passengers was Rebecca Aquarius. She was taken to the labs deep in the research center used for genetic enhancement. Along with 5 other female passangers, she was enjected with a syrum to make her pregnant with a baby. The baby was to be able to feed of blood only and to survive deep in the ocean. After 5 years of failure their dream came true. Rebecca gave birth to a mermaid that could survive off the blood off fish alone. A day after birth she was injected with nanobodies to form a barcode on her back. The barcode was used as a tracking device in case she escaped but it was unneccasary. Sushi was the baby, and she was born into training. She knew nothing of freedom or of love or of any care. She only know cruelty and pain. One day on a training mission, Sushi deicided to swim farther then the other mermaid children. She was attacked by sharks, wounding her. That is what gave her her name. The research lab deicided to feed her to the sharks to see how long she could last since they thought she would never recover. That night, one of the nurses gave her a syrum to make her wounds feel 20% faster. The nurse then took the child to secret cave where others had escaped to. The child was only of 7 and asked about her mother. The goverment had agents tell the children that their mothers where away on a trip when actually they had been drowned after they gave birth. Few females were keep and Sushi's mother didnt make the cut. Sushi swam away from the island and was found on a beach passed out 3 days later. She swore to herself to avenge her mother and destroy the labs that made her. She is being hunted by the goverment everywhere she goes, but she'll fight until she will finally get her freedom.
