Blood Feud! Shinsengumi

(from ebookjapan):

The town of Kyoto at the end of the Edo period. The "Mibu Roshitai," a group of samurai from Mito, is charged with maintaining public order in the midst of the conflict between the Kinno (loyalist) and the Sabaku (shogunate) factions. When Serizawa Kamo and others from Mito behave arrogantly, Isamu Kondo and others from Bushu are ordered to kill Serizawa.

The "Mibu Roshitai," which had killed Serizawa and others, was given its official name by the Imperial Court, and the "Shinsengumi" began its full-fledged activities!

The lives of the men who devoted their lives to the bushido, as portrayed realistically by the master mangaka, Takao Saito, are depicted in this authentic jidaigeki!
