Kalifa is a slim woman with blue eyes and glasses that, like Kuro, she often pushes up. Her blonde hair was about shoulder length when she first infiltrated Water 7 and she grew it out over the years she spent undercover there. She kept it tied up in a bun as a secretary, but let it fall freely with a left sidelock when she was revealed to be an assassin.
She has small studded earrings and usually wears outfits that reveal her legs, something Paulie often chides her about while she was undercover. When she was Iceburg's secretary she wore a yellow long sleeve jacket, and high-heel boots, but as an assassin, she wore a long-sleeved short black dress over a fishnet shirt and stockings along with black gloves and high-heels.
In the Volume 44 SBS, it was revealed that Kalifa was very bookish as a child.
