Nagi looks similar to Idate in terms of genetic appearance, such as the head fin, tail, two white spots on their heads, and their monochrome palette. Her eyes are black with white pupils. Her hair is a dark gray, and has a straight cut bangs, while her long hair is in twin braids. Her tail is a somewhat light gray, and is white underneath. Nagi sports a school-themed long-sleeved black shirt with a thin white bow on her chest area, while there are two thin light gray marks on her collar and the cuffs of the shirt. She wears a white turtleneck that is quite thick on her neck. Nagi also pairs her shirt with a black pleated skirt with two thin gray stripes at the bottom of the folds. Underneath the skirt is a lace-like petticoat. She wears white stockings with black uniform shoes (Mary Janes) to go with it. Her nails are a light gray.
Although not seen in too many of Deep Sea Prisoner's comics, the comics that Nagi does appear in suggest that she's very practical, although being treated like a child by her uncle, Idate. She seems to have envy towards Rocma, as she steals most of her uncle's attention.
Not much is known about her.
