This is a story of a world where monsters appear in Japan, but Japan becomes a super resource-rich country thanks to the materials from the monsters that are defeated. Kazami Makoto was an ordinary boy who aspires to be a monster hunter. One day, he is attacked by monsters and trapped in another world. He somehow manages to escape from the other world, and is the only person in the world who can use magic from the other world. Makoto learns that the magic of the other world is more effective against monsters than the police or the Self-Defense Forces, so he throws himself into the dangerous other world once again, risks his life to conquer it, brings the magic back to Japan, and becomes a monster hunter recognized by everyone as an SSS rank.
