Crusch's knight. Strong in Water Magic, which includes healing. Refuses to use a sword. Despite a feminine and cat-like appearance, Felix is called a male by other characters. However, Felix speaks often in the third person, using both male and female pronouns for themselves. It is implied that Felix has no set gender identity, and only uses male identifiers to tease other characters. A "Beast Human" hybrid, Felix was abandoned at birth, and later rescued by Crusch herself.
