Shukusei Shinsengumi

Near the end of the Tokugawa Shogunate, the "Shinsengumi" stood under the banner of righteousness!
However, while the Shinsengumi was known for its discipline and bushido, there was also a dark side that carried out ruthless internal purges.
Yamazaki Shojo and Hayashi Shintaro are two members of the internal affairs squad who
will eliminate those who have lost the spirit of bushido and their sense of duty!
This is a "dark" historical drama that explores the depths of human nature!
