The 1860s. The Tokugawa shogunate is under sustained assault from rebel groups fighting to restore the emperor, and young people across Japan are organizing into clans and factions competing for control of Edo, the capital. Into this volatile situation, something else is stirring: divine and demonic creatures are gaining power beneath the surface of the conflict, drawn out under the leadership of the sorcerer Tenkai Kodzunu. The hero of this chapter is Tatsuto Hiyuu — an ancestor of Tatsuma Hiyuu, the protagonist of the earlier Tokyo Majin games — fighting to control the same forces that his descendants will one day face again.
