Kureha is a 141 year old doctor. She has a eccentric treatment of patients, going as far as violently threatening them if they do not follow her orders and forceful methods of checking for injuries. She also punches people who call her "old" or a "hag" hating being called old and often begins conversations by asking if whoever she's speaking to wants to know the secret of her youth. Kureha seems to have a drinking habit. Despite her cold demeanor, she does have a loving side to her personality.
