"Ecole de Eden" is a boarding school for girls located deep in the forest, completely isolated from the outside world. The students there are selected beautiful girls, and they are orphans. It is a dream place for the girls, where they can receive the same education as the daughters of the upper class, including etiquette and dance. But in this paradise there is a rule that must not be broken! That rule is that you must not go out into the outside world, and breaking the rule means death. The only way to go out is the graduation exam, which is held at the "Palace" at night. What is the graduation exam that awaits them?
