Pun intended?

Well, you can do what I do, [url=http://en.wikipedia.org/wiki/Blood_types_in_Japanese_culture]choose a bloodtype based on personality of the character at hand.[/url] That's usually what they do in anime, games and the like, so that's what I almost always do. For the Rh, just put a plus or minus depending on what you feel suits the character.
