Rafarew is a female character with elf-like features: pointed ears, vibrant green hair extending to her shoulders, and striking red eyes. She wears fingerless gloves, shorts, and a tiara, complementing her youthful, teenage appearance.

In the visual novel *Tristia of the Deep-Blue Sea*, she serves as a central protagonist, though her specific narrative functions or backstory remain undefined. The OVA adaptation positions her as a secondary character, briefly highlighting her "Big Eater" trait without deeper exploration.

Official media, including spin-offs and related *Deep-Blue* series entries, maintain focus on her visual design and role classifications, omitting elaboration on her personal history, motivations, or character progression.
