Shine On! Bakumatsu Bad Boys!

After a brutal assault by the imperialist gang "Masked Demons," the Shinsengumi's Eighth Division-Kyoto's shogunate-loyal law enforcement-is wiped out, leaving only Heisuke Toudou alive, though severely wounded. Pressured by feudal lord Katamori Matsudaira to restore the Shinsengumi, Toudou recruits eight convicts, offering them a chance at redemption by taking the names of the fallen captains. Seven agree, but the eighth refuses and is swiftly killed by the ex-assassin Sakuya. Toudou struggles to mold these criminals into loyal fighters. His efforts are complicated by Ichibanboshi, a hotheaded and vengeful recruit whose family was killed by the Masked Demons, jeopardizing Toudou's plan. Meanwhile, as Toudou vows to defend the shogunate against imperialists and foreign threats, rival factions like Kogorou Katsura's group begin advancing their own schemes, aiming to seize control as the Edo period nears its end.
