The year 1864: The Shinsengumi, the shogun’s armed force in Kyoto ripped the city apart, with blades in hand, searching for pockets of resistance, slaughtering the samurai who sought to bring down the shogunate and restore Japan’s emperor to power. By chance, Murao Mayumi and his sister Shiho, meet samurai Kurata. Murao, seeking his fortune with his sword-arm, will join Shinsengumi, never suspecting his friend Kurata is secretly Kurama Tengu, who hides his face in a black hood, and who will tear a bloody swath through Shinsengumi’s massed blades, to aid the samurai who had taken up the emperor’s cause. Will friend kill friend in a time of war?
