Goal oriented and strong minded, type B's will start a task and continue it until completed, and completed well. Type B's are the individualists of the blood group categories and find their own way in life.
People with blood type B are the most practical of the blood groups. They are specialists in what they do. When they start a project, they spend extra time understanding and trying to follow directions than others might. When they are doing something, all of their attention is focused on it. They tend to stick to a goal and follow it through to the end, even if it seems impossible. They tend to be less than cooperative, as they like to follow their own rules and their own ideas. They are individualists. B type people pay attention to their thoughts a little more than their feelings, and therefore can sometimes seem cold and serious.
People with blood type B are often considered more relaxed, freewheeling, and unconventional than other types, although not necessarily to an unacceptable degree. In anime, the genki, off-the-wall types are type B, along with any kind of well-intended character who's ruled by their impulses.
