Jatt

Sister Jatt was a member of the Sisters of Plenitude. She lived on New Earth in the city of New New York. She monitored the experiments on the humans in the secret Intensive Care Unit beneath the Hospital on New Earth. Trying to escape from the infectious patients, Jatt became their first victim when a patient's hand brushed against her face, spreading its numerous viruses into her immunity-free body, killing her instantly.
