Gin's world view is set, and there are guest appearances by Gin's characters, but there is no political struggle, no celestial beings, no Shinsengumi, no return group, no generals, and no celestial guides; but there is a master house, a Yoshiwara flower street, a gang, a police station, and a chaebol.
