A Corpse is Buried Under Sakurako's Feet.

桜子さんの足下には死体が埋まっている

High schooler Shoutarou Tatewaki spends his days with Sakurako Kujou, a wealthy woman in her mid-twenties whose only real passion is bones, the cleaner the better. Whenever the two go out together in the city of Asahikawa, Hokkaido, they have an uncanny habit of stumbling onto human remains, which Sakurako examines with the eye of a forensic specialist while Shoutarou gets pulled into piecing together how the person died. This manga adapts the light novel series of the same name.
