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