Phryne is the daughter of a priest. She has sudden outbursts, like when she begs for Clain to let her see his smile. She has gotten close to him and they spend a night in a lot of ancient ruins together. Phryne's wish upon the day star was for "Clain's smile to persist forever".

She is later to be revealed as one half of the Fractale system, representing the "body" of the goddess the Fractale followers worshiped in the past. Nessa represents the "mind" of this goddess and also Phyrne's younger 10 year old self. Barrot is trying to unite the two halves of the goddess in order to restart the Fractale system to maintain power and control of the people. Phryne and Nessa both decide eventually to reunite to become the "key" to the Fractale system at the same time Lost Millennium destroys the sky-bound Temple. In the end, the Fractale system lives on, though it will eventually die off, forcing humanity to ween itself off the totalitarian regime of the Fractale and learn how to become people once again. It is revealed that she and Nessa both occupy Phryne's body after they become the key and live with Clain in his house.
