Seras

Seras was originally a completely normal policewoman. After a disastrous encounter with the wrong man, she was taken hostage. Suddenly, a mysterious figure appeared out of nowhere. He gave her a choice: leave this world—or trust him. She chose to trust him and allowed him to shoot through her in order to kill the target standing behind her. As she collapsed to the ground, he approached her and bit her neck. To prevent her from dying, he turned her into a vampire.
