Aoi "Frankie" Kisaragi is an 18-year-old girl with a striking and hauntingly unique appearance. Her long, jet-black hair falls in smooth, straight layers down her back, contrasting sharply with the severe scarring on her face. The entire left side of her face is burned and deep red, the skin uneven and rough. She has no lips on the left side, leaving her teeth partially visible even when her mouth is closed. Her nose is absent, giving her profile an eerie, skeletal elegance.
