It has been 50 years since a natural cataclysm unleashed a horde of monsters upon the Earth. In this new world, where effective human weapons do not exist, there are 'first-class pioneers' who can transform themselves into strong warriors using the power of special crystals. Kuroki is a 'second-class pioneer', who surveys the areas where the monsters have been wiped out. Along with his partner Pomukichi, a small dog, he sets out to investigate an area outside Tokyo. But when he gets there, a monster appears...! Kuroki, a non-pioneer, has no countermeasures, until he accidentally discovers a crystal, and is transformed into a giant invincible dragon...?

Fifty years after the Earth Expansion, humanity embarks on a daring mission to remap the world! Second-Grade Pioneer Ryusei Kuroki and his loyal Pomeranian partner, Pomukichi, are investigating uncharted lands outside Tokyo when a strange phenomenon suddenly transports them to Yokohama City, Kanagawa Prefecture. Together with first-Grade Pioneer Kohane Kanzaki, they meet Yokohama's leader, and a young girl named Ginna. But the situation in Kanagawa is dire - and about to get a whole lot worse. Even with his newfound crystal abilities, Kuroki and his new allies soon find themselves seriously outgunned in a desperate battle for survival.

Fifty years after the Earth Expansion, humanity embarks on a daring mission to recreate the world map! Kuroki and Kanzaki have returned from their amazing adventure in the lost Kanagawa district. But instead of being hailed as a hero, Kuroki has been stripped of his rank by the Pioneer Council! Now, his only chance to regain his license and truly become a First Grade Pioneer is to ace the upcoming Pioneer examination. But once in the test arena, Kuroki discovers the greatest danger will come not from the monsters he faces, but from a deadly group of rival Pioneers!
