Whether a person has blood type A, B, AB, or O is an important criterion in animes. Certain character traits are assigned to them.
Where does the myth come from? The concept of blood types and their character traits originated in the early 20th century. The Japanese doctor Kimata Hara published a research report suggesting a connection between blood types and temperament.
This work was later taken up repeatedly by psychologists and journalists, and it has now carved out a fixed place in Japanese anime culture. Even Studio Ghibli assigned its staff by blood type.
It is important to mention: Whether blood type and character are ultimately actually related, there is still no decisive proof of this.
There was also a scene in Naruto where Orochimaru asks his companion Kabuto about his blood type. Kabuto replies that he is blood type AB – while Orochimaru would have guessed him to be A.
Certain traits are always associated with the same blood types. If you want to know which characters you sympathize with in a new anime, you can already check this with a glance at the blood type.
The blood type and its meaning in anime
Blood type A
- Known characters: Jonathan Joestar (JoJo’s Bizarre Adventure), Rika Sasaki (Card Captor Sakura)
- Traits: perfectionists, team players, high sense of responsibility
Characters with blood type A are considered very conscientious and organized. They are perfectionists who pay great attention to detail and take responsibility. Such characters are diplomatic, friendly, and seek harmony.
Their weaknesses include a tendency to be oversensitive, anxious, and tense. They take criticism personally and need time to open up.
Characters with this blood type are rarely the hero. Instead, they are often a strategic sidekick or an organizer who supports the hero.
Blood type B
- Known characters: Naruto Uzumaki (Naruto), Monkey D. Luffy (One Piece)
- Traits: creative, passionate, extroverted
Characters with blood type B are free-spirited, independent, and optimistic. They are considered the most creative of the blood types. Such characters pursue their goals passionately and are doers.
But they also have weaknesses: Due to their honesty and tendency to express their opinions openly, they are sometimes perceived as egoistic and conventional or irresponsible. They pay little attention to the feelings of others.
This blood type contains many heroes from animes who tend to be more chaotic. They do not think things through and jump from one adventure to the next. Luckily, they can rely on their friends with other blood types.
Blood type AB
- Known characters: Vegeta (Dragon Ball), Mikasa Ackerman (Attack on Titan)
- Traits: complex, adaptable, mysterious
The rarest blood type is seen as a combination of the precise traits of blood type A and the free spirit of blood type B. They are often calm, rational, and analytical. Such characters can be difficult to assess by others.
Characters of this group are sometimes referred to as geniuses or “psychos” as their personality can be complicated and variable. However, they can also be spiritual.
This blood type is often suitable for antagonists, geniuses, or mysterious characters. It can appear in all areas of an anime.
Blood type O
- Known characters: Shinichi (Detective Conan), Deku (My Hero Academia)
- Traits: self-confident, optimistic, unpredictable
Characters with blood type O are born leaders. They are optimistic, determined, and have great self-confidence. Such characters are sociable, can easily get along with others, and are considered visionaries who see the bigger picture.
However, their strong personality can lead them to appear arrogant, jealous, or possessive. They are good organizers, but often have difficulty showing their true feelings.
This blood type often appears in animes among protagonists, heroes, and leaders. However, only among those who do not sink into absolute chaos.
