Journalist Takashi Hayami meets Ai Katsuragi, a member of a religious organisation, Tenmu Jinshinko, which meets secretly at the tomb of the Emperor Nintoku and which adheres to the nomadic way of life of its ancestors. They rely on the company Ikarino to fund the various political, social and cultural activities they promote that protect their unique lifestyle. But when Ikarino becomes a giant conglomerate that destroys the forests and mountains that form the foundation of the Tenmu Jinshinko, Hayami must join the group's struggle.
