Areas (Japanese: エリア) are individual levels in The Legendary Starfy series, found within Stages. They were introduced in Densetsu no Starfy 2 as the Stages in Densetsu no Starfy are levels themselves.
In Densetsu no Starfy 2 and Densetsu no Starfy 3, there are secret areas that become available as soon as the player beats the game once and extra secret Areas that become available after the player upgrades a Vehicle. In Densetsu no Starfy 4, there are no secret areas, although the Answers Cards available after beating the game once are used to get past the Tobira Majin that block hidden parts of the area.
In games prior to The Legendary Starfy, the player can return to the Area Select or City by holding Select+Start on the Pause Menu, provided that the player has beaten the game once. In The Legendary Starfy, the player can use the Back to Map option to return to the Map, provided that they have already beaten the area. Alternatively, the player may talk to Globerto to return to the Map and have the option of returning to the place where they left. In Densetsu no Starfy 4, there is an exit that leads back to the City for every area.
In The Legendary Starfy, the areas have actual names. The names differ for every Stage apart from the secret areas that are all called "????" or "Area Secret (number)" and the areas in the ??? Stage which are all called "Time Attack!".
In The Legendary Starfy, secret areas (excluding the areas of Pufftop and ??? if they are to be counted as secret areas) are unlocked by winning Side Quests and the player does not have beaten the game to unlock them. There are no Side Quests to unlock extra stages in the Pufftop and ??? stages that are only playable after beating the game.
