Chizuru Yukimura heads to Kyoto to search for her father. While there, she witnesses a fight between Rasetsu and members of the Shinsengumi. The Shinsengumi take her into custody and, once learning she is the daughter of the doctor they are searching for, decide to keep her close at hand. Chizuru follows the Shinsengumi in their battles to help the shogunate.
Here's a little historical background about Shinsengumi:
The Shinsengumi (newly selected corps) were a special police force of the late shogunate period.
After Japan opened up to the West following U.S. Commodore Matthew Perr's visits in 1853, its political situation gradually became more and more chaotic. The country was divided along various lines of political opinion; one of these schools of thought (which had existed prior to Perry's arrival) was sonno joi: "Revere the Emperor, Expel the Barbarians." Loyalists to the Emperor of Japan began to commit acts of murder and violence in Kyoto, the imperial capital. In 1863, responding to this trend, the Tokugawa Shogunate formed the Roshigumi, a group of 234 masterless samurai (ronin), under the nominal command of the hatamoto Matsudaira Tadatoshi and the actual leadership of Kiyokawa Hachiro (a dynamic rōnin from Shonai Domain). The group's formal mission was to act as the protectors of Tokugawa Iemochi, the 14th shogun, who was preparing to embark on a trip to Kyoto.
The Rōshigumi was funded by the Tokugawa regime. However, Kiyokawa Hachirō's goal, which he revealed following the group's arrival in Kyoto, was to gather rōnin to work with the supporters of the emperor. In response, thirteen members of the Rōshigumi became the thirteen founding members of the Shinsengumi. Other members loyal to the Tokugawa government returned to Edo and formed the Shinchōgumi 新徴組, which came under the patronage of the Shonai domain.
What does it meant to be a true warrior? A true warrior is those who sacrifices himself, even his life, in order to protect his country and loves ones. We can see true warriors in the Shinsengumi clans.
No matter what obstacles lies ahead and whomever the enemies are, they never admit defeats and continues to fight for what they believes in.
Their swords are not swords that kill but save people. We also learn that strong does not mean body but spirit and emotional.
This anime also plays with these theme; loves, hate, conflict of principal between the characters, and confusion within oneself in determining what to believes in.
With interesting story lines and so many handsome guys, this anime is one of the "must-watch anime"
