Mitozu - a small town lost in the mountains, population 6000. Every evening at 6 heavy bell tolls start resounding down the streets. Everybody knows that after the bell sounded you must not go out until the Sun rises again. But one day this law is broken by an ignorant outsider who just returned home after 10 years in Tokyo and the horrible apparition known only as Myoudo-sama has finally found a victim to prey upon.

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! (Source: Nihonbungeisha, translated)
