In an alternative timeline where the samurai didn't disappear after the Meiji Restoration, a rising tide of ghosts—commonly called samurai spirits—assails modern-day Shinjuku, Tokyo. These spirits frequently possess the bodies of the living and then go on rampages.

This is the start of a historical modern-day drama that follows the journey of a young feudal lord living in the present! (Source: Comic Walker, translated)
