After the highly acclaimed success of its predecessor, Compile took a slightly more retro approach, so players had a more original feel to the game over that of 2.

Satan (Dark Prince in the series' English localizations) has used special magic to make the Sun bigger on a remote island, hoping to create a paradise where he can relax surrounded by girls in bikinis.

Draco Centauros, in the Easy difficulty, uses this as an opportunity to find a spot to get a tan, but gets a sunburn in the ending.

Arle Nadja and Schezo, in the Normal and Hard difficulties respectively, find the weather too extreme.

Both of them set out to find Satan and stop his plans, but are repeatedly interrupted by others such as Zoh Daimoh, Draco Centauros after her storyline, Suketoudara, Lagnus the Brave (Ragnus in later games), Rulue, and even each other.
