Alus Reigin is sixteen years old and already a legend. As the top-ranked Magicmaster in a nation of more than 100,000, he has slain more Fiends and won back more of humanity's lost land than anyone alive. When he asks to retire from military service, fate takes an unexpected turn. He ends up enrolled at a special magical institute, concealing who he really is while training two gifted Magicmaster girls as his successors. The Fiends still roam the world, and Alus keeps defeating them in secret, balancing the student he pretends to be against the warrior he actually is in this action fantasy adventure.
