Blood can be clearly distinguished as being different to any past Japanese animation features for several important reasons. The original concept of BLOOD was developed by Mamoru Oshii, the director of Ghost in the Shell. After the bloody introduction the viewer is clued up on an undercover demon slaying assignment. Saya - on behalf of a covert quasi government agency, poses as a schoolgirl at a college near an American airbase.
