ES (Eternal Sabbath) (エス エターナル サバス, Esu Etānaru Sabasu) is an eight-volume manga series by Fuyumi Soryo.
ES (Eternal Sabbath) is a gene developed by a group of scientists who sought immortality. The presence of the gene grants the carrier up to 200 years of life immune from all viruses. Though the scientists' original intention was to demonstrate the feasibility of eternal life, ES unexpectedly has the additional power of mind-control and memory-alteration.
A female neurology professor, Mine Kujo, meets a man by the name of Ryosuke Akiba and discovers that he is a genetically engineered human with the ES gene. Together, they pursue a more dangerous ES-carrier who had escaped from the research center.
