As a child, Karen was abused by her mother. When her mother died, she was left all alone and grew up by herself. Despite what she went through as a child, Karen remains true to her Christian beliefs.

As a much older woman, Karen works at a bath house called "Flower" and is the hostess. For everyone who has only seen the movie, I say this once, she is not a stripper!!!! Nothing much else is known about Karen.

Karen is a very strong person who is always willing to help others. She is very deticated to her future as one of the Seven Seals, a Dragon of Heaven. She has the ability to control fire.
