Upon waking up, the world has completely changed. The familiar high school now teaches magic, telling everyone to become an outstanding mage. Outside the city where people live, monsters and beasts roam, eyeing humans hungrily. The world that once revered science now worships magic, yet there are still teachers who see him as a hopeless student, classmates who look at him strangely, a father struggling at the bottom of society, and a pure but immobile... However, Frank Morgan discovers that while most people can only major in one type of magic, he is a mage who can master all elements!
