During Japan's Bakumatsu period, the Shinsengumi's Eighth Division is virtually annihilated by an imperialist criminal gang known as the Masked Demons.

The sole survivor, Heisuke Toudou, is badly injured, losing a hand and a foot.

Toudou is tasked by local feudal lord, Matsudaira Katamori, to maintain order, so he offers eight convicts who have been sentenced to death the chance to redeem themselves by abandoning their old names and becoming replacements for the eight dead Shinsengumi captains.

Seven prisoners, Sakuya, Bou, Sougen, Gatarou, Suzuran, Akira and Ichibanboshi accept the offer, the eighth is immediately executed.
