Eva

Eva only appears for a short scene in the comic, however she is seen to take her job very seriously. She is a skilled Hunter, and often works with Jack. When Jack almost dies because of his recklessness, Eva scolds him. It is later revealed that Eva often gets mad at Jack, and when she does, she stays angry for long periods of time. It can be implied that she is both very annoyed with, and deeply cares for Jack.
