Blood type

A blood type is a classification of blood based on the presence and absence of antibodies and inherited antigenic substances. In Japan (and other East Asian countries),. This is similar to belief in astrology. This is the reason some Final Fantasy characters have their blood type listed in their official biography, such as in the manual or guide books, even if it has no gameplay significance. The games whose characters' blood types are known are Final Fantasy VI, Final Fantasy VII, and Final Fantasy VIII, although not every playable character from these games has a defined blood type, at times because the character is not human.
