The Bakumatsu was a period when young men's hearts were filled with worry about their country's future. Takasugi Shinsaku, a Choshu soldier of fortune, sneaks onboard a government ship with his friend Katsura Kogorou in quest of a mysterious "timepiece" with the potential to manipulate time, which he suspects the government wants for itself. Takasugi intends to destroy the relic rather than allow such power to slip into the wrong hands, but after obtaining it, the artifact is swiftly stolen, prompting the two to track down the mysterious thief to Kyoto's government seat. When they reach in the city, however, they learn that the government has been deposed and that Susanoo, the deity, now reigns supreme.
