During the political upheavals and social strife at the end
of the Tokugawa Shogunate in Japan (1855),
two parent-less brothers Yukimura Shoutarou
and Yukimura Gentarou struggle to survive in these turbulent times.
With their only possession being their deceased father’s sword
and clinging onto the wisdom of their mother’s final words,
the brothers seek to embark on the Path of the Warrior: Sidooh.
