Hokkaido, 1932. Ichiro Soga, a brilliant young student at Tokyo University of Art, arrives at a remote golf estate run by his uncle, expecting a quiet summer job. But fate draws him into a breathtaking spy story, where international intrigue intertwines with a dark secret buried deep beneath the earth. A subterranean mystery, rooted in the recently concluded Taisho era, leads Ichiro to a startling discovery. Through hidden tunnels, foreign agents, and betrayal, Ichiro must navigate a labyrinth of suspicion and danger, testing his wits and courage to unravel a conspiracy that threatens the future of Japan and beyond. Featuring the legendary art of Ippei Kuri, co-founder of Tatsunoko Production, this original manga combines the evocative atmosphere of the Taisho era with a gripping narrative of espionage and action. WARNING!!!! Never before published in Japan, this work is a direct gift from the master Kuri, who chose Italy for its first complete edition in recognition of the publisher's exceptional dedication to publishing Kenshiro Tsubanari and the Demon Slayer Sword. Completed shortly before his death, this edition is his first and only publication worldwide so far. Ippei Kuri is the co-founder of Tatsunoko, creator of cult characters such as Kyashan, Polymar, and Tekkaman. Having passed away in July 2023, this manga is a WORLD PREMIERE from Nippon Shock Edizioni.
