As I got more and more involved in manga I began to notice that in the character profile pages blood types were mentioned. The first time I saw it I thought the author was just being funny/cute about some irrelevant fact about the character. But soon I began noticing it in all my series. Although I raised an eyebrow at that random fact I never really bothered to look up why it was mentioned. I just thought that blood type was a physical characteristic that the Japanese liked to share and nothing more.
After watching a few anime series I finally caught on to what the characters were implying when they mention their blood type. Off the top of my head a series that explains it fairly well (indirectly) is Lucky Star in episode 9. Blood types in Japan are the eastern equivalent of a zodiac sign (astrology), so when you tell someone you blood type in Japan it’s like saying “Hi I’m an Aquarius” . This belief that your personality is derived from your blood type was started in 1927 by Takeji Furukawain. Although he had no credentials in the field, and scientists objected to the blood type personality theory strongly, the media and public still took to it.
Calm in emergencies, strive for success, very responsible, and are perfectionists. Although they try to get along with everyone they often feel out of place. This is considered to be the most creative (and artistic) type.
Examples: Sakura (Cardcaptor Sakura), Yuki (Fruits Basket), Kyo (Fruits Basket)
More in touch with their thoughts than with their feelings so are often seen as cold. The most practical blood type. Once undertaking a project they are completely dedicated and involved in it until completed. Tend to be less cooperative and do things by their own rules. The majority of Japan is type B.
Eaxmples: Naruto (Naruto), Kagami (Lucky Star), Sagara (Rurouni Kenshin)
Any combination of traits from both A and B types. The unpredictable type, their moods/attitudes may be prone to quickly changing. Responsible and trustworthy but can only handle so much responsibility.
Examples: Misa (Deathnote), Tomoe (Sailor Moon), Gaara (Naruto)
Have a lot of confidence, values the opinions of those around them, and are often the center of attention. Will excitedly start many projects but rarely actually completes any of them. Outgoing, energetic, and sociable but not dependable. Will often speak whats on their mind.
Examples: Goku (Dragonball), Vash (Trigun), Rin (Fate: Stay/Night)
A is most compatible with A and AB.
B is most compatible with B and AB.
AB is most compatible with AB, B, A, and O.
O is most compatible with O and AB.
Based on this basic knowledge of blood types can you guess the blood types of any of these characters?
I think the blood type thing is cute and probably a great conversation starter (in Japan), it’s also kind of interesting that they’d go so far as to give fictional characters blood types. But personally I don’t care for this sort of thing (Myers Briggs, Astrology, etc…). I don’t like anything that tries to summarize and categorize people and their personalities. I also sometimes wonder that in giving their characters blood types authors create limitations on how the characters can develop, obviously I have no idea if that concern is really true. Although one time I had to take a Myers Briggs test for school and they said my type was “the type that dislikes this category system”…so I guess they showed me
