In most anime, if you find character statistics, they almost always mention what the character's bloodtype is: A, B, AB, or O. This is because more than 72 percent of Japanese belive there is a relationship between a person's personality and their bloodtype. There have been a number of best-selling books in this field in Japan, and research has been done by English and French psychologists as well. There are a variety of published papers that say both that a person's bloodtype does and does not have anything to do with their personality, so you can decide for yourself.
