Cancer Kafka

The Red Team's combat leader. Like all the members of the Red Team, Cancer is the descendant of a group of settlers whom Dianna abandoned on Earth over 100 years ago. Cancer is a fierce and boisterous warrior. She stays loyal to the Queen in spite of the poor treatment her people receive from Dianna Counter, and sacrifices her life to keep Dianna Soreil out of the hands of Gym Ghingham.
