The main character of Choujigen Game Neptune. While depicted as a preteen girl without a single care in the world, Neptune is actually one of the four goddesses of Gamindustri, presiding over the Land of Purple Progress, Planeptune. After losing a fight with the other three goddesses in the world of Celestia, she is banished to the earth below, driving into the ground headfirst and losing her memories.
Her regular appearance consists of a hoodie dress with drawstrings that resemble controller plugs, striped socks, and hair clips shaped like D-pads. Her eyes are purple, and so is her short, rather messy hair.
As Choujigen Game Neptune's characters are mainly personifications of game companies or game consoles, Neptune represents the long-canceled Sega Neptune.
