Compile Heart’s fictional video game world has four console inspired lands, each ruled by a different goddess. Neptune is the main character of Super Dimension Game Neptune and she rules Planetune.
Neptune (Purple Heart) – Goddess of Planetune
Green Heart – Goddess of Leanbox
Black Heart – Goddess of Raystation
White Heart – Goddess of Ruii
The art above with Neptune in a snazzy leotard and X’s in her hair is after her transformation. Neptune is actually a little girl who appeared in the game world during a dark hour. The nefarious Majiconnu (a play on the word Majicon – or flash carts) is making monsters – monsters you have to fight.
