Kosuke Fujita, a Japanese, landed alone on an uninhabited island that no one could approach due to nuclear tests and plant cell tests in the 1950s in order to make a scoop. What Kosuke saw there was a town of cats who walked on two legs and spoke Japanese! Hiroshi Masumura's masterpiece, which develops his own fantastic world, is here!
