Synopsis

The manga is set in a world where "demon-possessed" individuals appear every time there is a great disaster or war. The demon-possessed wield demonic powers, and if left unchecked, will use them to fulfill their selfish desires. The Holy Endor Academy was established to counter, secure, and re-educate these demon-possessed individuals. One day, a seemingly normal high school student named Konoha Himesaki enters as a low-class criminal, but she is in truth a powerful magic user.
