Actual name is ES00 or "Shuro", named after the palm leaves in the bible. In Catholicism, a cross applied to the forehead with the ashes of shuro leaves a sign of repentance. Perhaps this name was born of the researchers' feelings of guilt for playing God and creating a human being; he is a genetically engineered human, made by the National Hygienic Laboratory. Though unexpected by the research staff, he was born with a power to "hack" into other people's minds, save for a few. The ES gene grants him a lifeline of at least two centuries, and a flawless immunity system. "Ryosuke Akiba" is actually someone else's identity Shuro uses through his powers. The real Akiba previously died in an accident. Shuro has a slight sense of justice and morality.
