In a world where people awaken combat professions at eighteen, wealthy, work-averse Lin Mo receives the supposedly useless Blank Slate Mage class. His basic fireball develops a mind of its own and hunts monsters while he rests, letting him grow rapidly; soon, his other spells awaken too, each with its own eccentric personality.
