The Seven Star College has nurtured generations of young psychics. But centuries of prestigious education are there to paint over the vicious treatment of its low-achieving students. Christian Friedd, sophomore dropout, is the latest admission. An outsider who has never displayed abilities and with no apparent link to the Esper community. He's been placed in the lowest tier of students, Class F.

Despite his best wishes to escape, a corrosive barrier keeps the students locked inside. And the zealous members of the Student Council watch over the troublemakers, particularly him. At Seven Star…escape is truly impossible.

Attend class in a magical school, where mysticism shadows the scientific knowledge at the heart of the Faculty. If no amount of skill, power or resolve gets you out of their Machiavellian grasp, will you find purpose inside the Prison?
