A type of blood developed to improve the oxygen and nutrient transportation efficiency of blood, as well as to provide a solution to the lack of blood available for transfusions. Based mainly on substances such as perfluorocarbons and fluorescein diacetate, which were used in the latter half of the 20th century for storing organs, it is also called "milk blood", because its red blood cells are white in color. It does indeed possess superior oxygen transportation efficiency and regenerative abilities, but the heavy burden it places on the kidneys makes it necessary for them to be genetically modified and for the user to undergo regular hemodialysis before it can be used for extended periods of time. For these reasons, it is not permitted for medical use among the general public; it is presently only authorized for use within the military and in members of BCP's AP Unit. In addition to milk blood, there is a second-generation powder type made with genetically modified hemoglobin, and a third-generation type containing 100% artificial blood cells, but both of these types are still undergoing clinical trials.
A person using artificial blood has their original blood placed in cryogenic storage and can switch back to it at any time.
