It was the beginning of the Shouwa Era. A town in the mountains of the Hokuetsu Region, commonly known as “Cattown”, has been terrorized by a brutal series of cat murders! Meanwhile, a request is brought to Mayoiji Somari, who runs a small detective agency in a corner of the town. There's the client, Saibe Rian; Amemiya Shouta of Cattown Police Station First Investigation Division; the poet staying at the hotel Blue Cat Hall, Sakutarou; and the suspicious cat Tatsuishi Rii. Will Detective Somari, who only has athletic nerves and a sense of justice, be able to get to the bottom of the case!? This comic is based on the world from poet Hagiwara Sakutarou's only novel, *Cattown*, and accompanied by a stage performance that has already become a hot topic. The curtain opens on a Gordian Knot–cutting deductive action drama!!
