Julia is a character in Blood . She is a doctor working for Red Shield but is also involved in research into the Chiropterans.
Julia is a medical doctor who works for Red Shield. Initially we see her as Saya's doctor and the one who administers the blood transfusions for Saya. She is not only a doctor but a keen scientist as well and together with Dr. Collins she is committed to researching the Chiropterans in an attempt to find a way to destroy them. She has a great deal of affection for David although like David she never admits to that fact. When Riku is turned into a Chevalier she and Dr. Collins are able to gain insight into Chiropteran DNA at a level that they never had available before. Their research leads them to some startling discoveries about Chiropterans and this causes Dr. Collins to question whether or not Chiropterans should be killed. Dr. Collins knows that the discoveries he has made would make him famous if the world knew but as long as he works for Red Shield that research will never come to light. He voices his concerns to Julia and asks Julia to defect with him to Cinq Fleches and betray Red Shield. Despite her feelings for David and the others the scientist in Julia cannot resist continuing their research and she agrees. While working for Cinq Fleches she encounters David and he shows no bitterness towards her and lets her know she can return to Red Shield at any time.
