Vertin

Vertin (维尔汀) is the main protagonist of Reverse: 1999 and the character controlled by the player. As a member of the St. Pavlov Foundation, she is currently known as the only person able to withstand "the Storm" thanks to an antibody in her body named 'Asymmetric Protein G' which only she posseses from the Foundation's experiments, having been given the title "Timekeeper" as a result. She wishes to find the truth behind the storm and the Foundation that she grew up in, this being a result of her recalling memories of her mother, whom she was previously unsure if she even existed at all, during her first storm. However when she went to ask the foundation, she was met with the response of "no such person".
