A single woman has forced her male counterparts at an inter-company gokan to submit to blood testing for personality verification.

“It’s important to group human beings into personality types, of which there are only four different categories known to man,” said Fumi Oita.

“I will only date someone with a blood type B personality.”

Blood type B people are known to have specific personality traits, which include “creative”, “passionate”, “animal loving”, and “individualistic”.

People who are not blood type B include Danny DeVito and Michael Flatley, best known for starring in the Irish dance show Riverdance.

“I would hate to end up marrying an animal hater like Michael Flatley,” said Oita.
