This is a fan work of "Magic Forbidden Book Catalogue", and some settings of "Puppet Circus" are added at the same time. A circus-born traveler enters Academy City to study and live as a puppet master; at the same time, he secretly fights against the constant coming to seize it. The enemy who mastered the original magic book, by the way, guards the safety and peace of the Academy City... the third world war? Dare to call it a world war without the mainland?
