In an alternate version of Japan, a multitude of superhumans coexist in a post-war era known as the 'age of gods.' Imagine a world where all the fantastical beings from myths and tales walk among society simultaneously – extraterrestrial Titans, mystical creatures, ancient phantoms, advanced cyborgs, and more. While some superhumans embrace their powers openly, others lurk in the shadows, concealing their true identities and engaging in clandestine battles. Amidst this complex landscape, secret organizations pose threats to these extraordinary beings, prompting the Japanese government to establish the Superhuman Bureau, a division of the Ministry of Health and Welfare dedicated to monitoring and protecting superhumans. At the heart of this bureau is Jiro Hitoyoshi, a key member tasked with the mission of identifying, managing, and safeguarding these unique individuals.
