==Layout==
The Last Defense Academy is laid out like a regular school, with things like a cafeteria, classrooms and multiple floors.
The academy is completely surrounded by a ring of pink flames known as the Undying Flames, which cannot be extinguished. This fire keeps the students trapped in the school and prevents most other beings from entering the area, but the school invaders and commanders manage to cross over and attack the students and school for unknown reasons. But the characters have no idea why they are targeting this school or what lies within it. (https://www.youtube.com/live/Azv7W8vOtQY?t=1353s) "In the background is the image of the academy with pink flames. They cannot be put out. They are completely encircling the academy at 360 degrees. While they serve as a barrier, enemies sometimes manage to cross over, so characters have to confront them. At the same time, the characters don't want to fight [...] They want to escape, but the flames prevent their escape, so it acts both as [a] wall and a cage. The characters also don't understand why this phenomenon exists. It's an eternally burning flame." (https://www.youtube.com/live/Azv7W8vOtQY?t=1313s)
