Rupa

A girl-type AI responsible for operating the ship Okeanos. She seems to be an idol within the server, as there are scenes of her singing on a large screen. Until Kyo remembers, she appears to have been substituting for Kyo's deceased sister, Misaki, and disappears at the same time as Misaki. In the novel "Entangle: Girl," she appears as a character AI in a movie contest within VR.
