A young man prepares to attend a magic academy, but on his first day he receives his career prognosis: Demon King, known historically as the man who tried to destroy the world.


30th century AD, in a world where magic exists naturally, 100 years have passed since a great war between the human race and the Demon King. The war concluded with a victory for the human race, though it made many sacrifices, and slowly but surely the civilizations are developing once again. One time, a witch walked down into a small town holding a newborn baby in her arms, she stopped in front of a church, put the baby in front of their door then disappeared.

Ten years later, the baby taken in by the church was named Sai Akuto ("Worst Evil"), and, even though he was raised in the orphanage, he awed and perplexed people with his preaching about love of mankind and equality like a man of virtue. Later Akuto decided he wanted to live in modesty so as not to trouble others, and before long a family offered themselves to adopt him. However, on the day Akuto left the orphanage, a new girl was brought to the orphanage. The girl cannot stop crying because of loneliness, troubling the adults around her. Akuto, having seen all this, decided to bring all his money given to him by the orphanage for his future living expenses and buy a hair ornament with a jewel on it. He handed it over to the girl to make her stop crying and promised they'll meet again someday if she stops crying and takes a good care of the ornament.

Five years later, Akuto passed the test to enter Constantin Magic High School, and left his foster father's home. He made a new friend on his way to the school, and he arrived at the school. He then underwent the vocational aptitude test, a test which is one of the school's rules to determine a student's future occupation. "Examination Numbers: Number 021, Name: Sai Akuto. Future Occupation: the Devil King"...
