An exorcist in Hokkaido armed with nothing but spite and a whip versus an entire prefecture of the undead, and she's losing to both the horny literary ghosts and the samurai with actual combat training. The show knows it has no budget and makes that the joke, Francesca herself is a zombie idol with all the dignity of a malfunctioning marionette, and she's somehow the most competent person on screen. You're watching a comedy that refuses to explain why any of this is happening or whether it's supposed to make sense, and that refusal is the entire point. For viewers who want their supernatural nonsense served chaotic and unglamorous, with just enough heart underneath the chaos to care when things go sideways.
A young girl known only as Exorcist works in Hokkaido, wiping out the zombies that have been plaguing the region. She can deal with the lecherous Takuboku Ishikawa, but the revived Shinsengumi, Hijikata Toshizou among them, have their sights set on Hokkaido and are more than she can manage. Amid the chaos she must rely on help from the undead idol Francesca and her dog Franken. The show is a comedic supernatural fantasy in short episodes, built around a character created to promote Hokkaido.
