somewhere in the cold asahikawa city, hokkaido, there is a young lady named kujo sakurako (voiced by ito shizuki). in addition to some narcissism, sakurako also has the quirk of using dead bones to make specimens, and she has a deeper knowledge of post-mortem. perhaps it was the almost paranoid love of corpses and bones that made sakurako involved in various incredible deaths one after another. during this process, ordinary high school student kawashima shotaro (voiced by junya koki) was also run around by sakurako, leading the nose, witnessing the moment when every case is solved. for the deceased, it is precisely because of strange people like sakurako that their grievances are revealed... this film is adapted from the light novel of the same name by ota muriori aaa
