Kubikiri Cycle: Aoiro Savant to Zaregotozukai

A gathering of exceptional minds on a secluded island promises stimulating conversation and little ordinary company. An unnamed young man accompanies the gifted Tomo Kunagisa to the mansion of Iria Akagami, where every guest seems brilliant in a different way.

Then a murder turns the isolated retreat into a closed circle of suspects. With escape and outside help limited, the visitors must examine not only the impossible-looking crime but the assumptions that make one explanation seem more convincing than another.
