There are a total of five regions available in テンドーブレード. In each region, the BGM is decided by the final boss's theme song.
Heaven
The Heaven area consists of the Heaven, and the UFO map.
Heaven
Starting point of the game. You can heal your party members and/or refill your spirits here. If Reimu is not in your party, she may be found here selling some items. If Suika leaves your party, you may also find her here.
UFO
First map after starting the game where you get to fight against enemies.
Scarlet Devil Mansion
The Scarlet Devil Mansion area consists of the mansion, the second floor, the library, and the basement.
Second floor of the mansion
Cannot be accessed immediately through portals. You can only get to the second floor through going up the stairs in the first floor. This is where you can fight Remilia Scarlet, the final boss of Scarlet Devil Mansion area. Koishi Komeiji can also be found here.
Library
Can only be accessed after meeting Patchouli in the mansion. If Patchouli is not in your team, this is where you can buy magic items from her.
Basement
Possibly the hardest map from the entire game, not due to the fact that the map is more winding than any other maps in Scarlet Devil Mansion, but because Flandre Scarlet, the de facto boss of this map, constantly back attacks in this map.
Bamboo Forest of Wandering
The Bamboo Forest of Wandering area consists of the Bamboo Forest, the Riverside, the Deeper Bamboo Forest, the Rabbit's Inn, and Eientei.
Eientei
Can only be accessed after Tewi allows the player in. This is where Kaguya Houraisan, the final boss of the Bamboo Forest of Wandering area, can be found. You can also find Eirin Yagokoro and, in a later event, Fujiwara no Mokou, in Eientei.
Youkai Mountain
The Youkai Mountain area consists of the Youkai Mountain, the Kappa's Freemarket, Moriya Shrine, and the Deeper Youkai Mountain.
Fantastic Wind Hole
The Fantastic Wind Hole area consists of the Fantastic Wind Hole, the Palace of Earth Spirits, the Den of Evil, and the Nuclear Fusion Reactor Core.
Other regions
Forest of Magic
This is where the player can meet Alice Margatroid. This map is the smallest map in the game other than all shop area maps. Though the Forest of Magic has no relations to the Scarlet Devil Mansion area in this game, the BGM for this map is Remilia's theme song.
Sea of Clouds
This is the final map where the player encounters the final boss, Nue Houjuu. Note that once the player enters this map, warping back to any other maps will be disabled.
