Julia Silverstein

Julia Silverstein is a doctor working with the Red Shield organization. Initially shown as the medical supervisor administering Saya's blood transfusions, it is later revealed that Julia is a highly skilled clinician who strives to support Red Shield with her research into chiropteran biology. While Julia primarily works with Lewis and David, she was brought to organization by Collins and as such, tends to remain loyal to his ambitions. Though she feels strongly for those around her, Julia approaches everything in life with clinical precision and thus finds it easier to deal with others analytically rather than emotionally. When her supervisor and mentor, Dr. Collins, defects to Cinq Flèches (due wanting to be able to publish his research and because he disagrees with the idea of killing the "superior"chiropterans) he is able to convince Julia to leave Red Shield with him. She meets with David several times while he is investigating Cinq Flèches and the Corpse Corps, and he always reminds her that she will be welcome back to the Red Shield when she is ready. When Diva becomes pregnant after raping Riku, Julia becomes her personal physician. This sends Collins into a jealous fit and he attempts to murder her, but David saves her and is shot instead. Afterward, Julia keeps vigil over the critically wounded David in the hospital and is shown kissing him while he sleeps. She also returns to the Red Shield and is able to use the knowledge she gained to aid them in the final battle with Diva. After Diva is killed and the group returns to Okinawa, Julia is able to use the knowledge she gained to extend the Schiff Lulu's life span and develop a serum from Saya's blood that can stop the effects of the Delta 67 agent. She also is revealed to be pregnant with David's child. (spoiler source: Wikipedia)
