Ivan and Daisy got to know during World War II. Ivan came to Daisy's house. Outside the bombs were falling down. Daisy asked Ivan to turn her into a vampire. Ivan did as she asked. Since then they moved through the world together. When Ivan was killed by the CenSSA, it made Daisy so angry that she committed the box tunnel 20 massacre to take revenge for Ivans death. Only a short time later Daisy was killed by McNair.
