Set in a university anatomy lab, this medical mystery gradually reveals the shape of a hidden secret and a revenge plot through a tube found in a corpse and a sinister four-line poem. It is a debut novel that turns specialist knowledge into narrative drive.

A four-line poem dropped into the dissection room throws the lab’s darkness into relief.

A coming-of-age mystery that follows events in the school arts building, where rumors of a ghost swirl before a farewell concert by the brass band. It combines the atmosphere of school life with the pleasure of puzzle-solving, beginning from an attempt to verify the ghost story.

On a night of ghost rumors, a high school student is called in as a neutral witness and faces the truth.

A full-length mystery in which a story about people fascinated by poison eerily resonates with an actual crime. Its structure, in which the embedded fiction and the outer case begin to slip apart, gives the book a distinctive aftertaste shaped by its delayed publication.

The story’s own "Dokusatsu Club" seems to draw real-world events toward it.
