Set in Kyoto at the end of the Edo period, the story depicts the intense and passionate lives of the Shinsengumi - the iconic samurai force that defended Kyoto in the final years of Japan's shogunate - through spectacular action and a bold interpretation based on historical facts. The story follows street brawler Toshizo Hijikata, who finds a new kind of family in Isami Kondo and Soji Okita. Hijikata and his comrades in the Shinsengumi forge a bond of loyalty - tested by betrayal, illness, and war - as they fight not only their enemies but their own ideals.
