Eighth part of Douluo Dalu.

Twenty seventh movie.

“Ever since that day...I lost hope for the future.” In 2021, Asumi, a salesperson at Kobe Steel, was having a difficult time finding meaning in her job while she felt helpless in the face of the company’s numerous issues. Just as Asumi was about to tell her boss that she wanted to quit, a mystical ray of light came out of a corporate history book and led her to Kobe in 1905. There she encountered visionary, high-spirited people from Kobe Steel's founding period. Torasuke was among them; he was a clumsy but enthusiastic young man from the Meiji era who dreamed big and believed in the potential of industrial development. Guided by the Kobelco Group's history, two persons from different eras set out on a journey across time, from its beginning to the present. They witness people get through tough times and continue to take on challenges with hope for a better future. After coming into contact with the founders’ spirits, they each choose their own path for the future.

The "Medicine Seller" is a deadly and mysterious master of the occult who travels across feudal Japan in search of malevolent spirits called "mononoke" to slay. When he locates one of these spirits, he cannot simply kill it; he must first learn its Form, its Truth, and its Reason in order to wield the mighty Exorcism Sword and fight against it. He must begin his strange exorcisms with intense psychological analysis and careful investigative work—an extremely dangerous step, as he must first confront and learn about the mononoke before he even has the means to defeat it. The Medicine Seller's journey leads him to an old-fashioned inn where Shino, a pregnant woman, has finally found a place to rest. The owner has reluctantly placed her in the last vacant room; however, as she settles in, it quickly becomes clear that the room is infested by a lethal band of mononoke, the Zashiki Warashi. With his hunter's intuition, the Medicine Seller begins his investigation to discover the Form, the Truth, and the Reason before the Zashiki Warashi can kill again. [Written by MAL Rewrite]
