Asumi steps into 1905 Kobe and meets the men who built the company she wants to leave, people still burning with purpose she thought was extinct. The show doesn't ask her to learn a lesson about hard work or corporate loyalty. It asks her to remember what it feels like when the future is still possible. That collision between burnout and vision, between the person she became and the dreamers who came before, is the entire weight of the thing.

Asumi works in sales at Kobe Steel in 2021, struggling to find meaning in her job and feeling powerless against the company's many problems. Just as she is about to quit, a mysterious beam of light bursts from a book on the company's history and carries her back to Kobe in 1905. There she meets the bold, idealistic people of Kobe Steel's founding years, among them Torasuke, a clumsy but eager young man of the Meiji era with big dreams and firm faith in what industry can achieve. Guided by the group's history, the two travel together from the company's beginnings to the present day, watching people endure hard times and keep facing challenges with hope. Touched by the founders' spirit, each of them decides on a path forward. The single-episode ONA blends drama, romance and the supernatural.
