The daughters of legendary samurai inherit their fathers' duty, not their swords, and spend their time hunting ghosts in Meiji-era Kyoto instead of fighting for a cause that already won. Comedy comes from watching girls in period costume treat paranormal bureaucracy like a job, complete with the exhaustion that implies. It's a fever dream that knows exactly what it is: four episodes of historical pastiche where the punchline is that legacy means showing up, even when nobody's watching anymore.
Meiji-era Japan needs protectors, and the daughters of former Shinsengumi members are called on to serve, much as their fathers once were. Kondou Yuuko, Hijikata Toshie and Okita Kaoru take on the job of guarding the country from its present troubles. Most of their work in and around Kyoto means putting down strange paranormal occurrences that keep appearing more and more often, while also shielding the city from any other threat that comes along. The four-episode OVA mixes adventure with comedy.
