Cynthia and her sister Catherine only had each other after they lost their parents, and were often bullied by other children. An elderly woman adopted them, but died in an accident a few years later. From then on, people started calling them the "Sisters of Doom." Those days lasted until Cynthia was recruited by the Meteor Corporation, where she was trained to be an agent. Although she gradually became suspicious of the organization during her missions, she chose to ignore it as she needed the job to support her family.

When the outbreak happened, her first thought was to rush to her sister's school. She breathed a sigh of relief when she saw her sister fighting off the Zombies with a chainsaw. Since that day, she has fought alongside her sister, killing countless Zombies with her superb marksmanship.

To her dismay, she later discovered that Meteor Corporation seemed to have something to do with the outbreak. She feels guilty for working for them in the past, and swears to find out the truth and atone for her mistakes.
