Neptune is the guardian goddess of Planeptune. She's the face and title character of the Neptunia series and possesses an upbeat and bright personality even in the face of adversity. She has decided to enter the Peach Beach Splash tournament on behalf of Gamindustri.
Neptune is a seemingly young girl with a petite frame. She has dark-purple eyes and messy lilac-purple hair with two d-pad hair clips. Her apparel consists a white choker with a light-blue d-pad symbol and a white one-piece swimsuit with an emblem attached to the ribbon on the chest area that has the letter "N".
She is a happy, excitable girl with a very strong sense of justice. Her ditzy personality causes her to be very careless at times which can either help her or land her into serious trouble. She makes friends rather easily due to her friendly nature and often gives them cute nicknames. People admire her optimistic outlook and confidence. She never gives up or backs down when the going gets tough and she makes sure to see her objective through to the very end.
