Inogashira Goro (Matsushige Yutaka) was in Setagaya waiting at a tennis court for a client (Owada Baku) to finish playing a match with friends. Much to his chagrin, Goro who is not much into ball-based sports, obliged the client's request to practice swinging the racket... After their meeting, Goro managed to follow a somewhat vaguely drawn map towards Kyodo station. He felt hungry after experiencing relief from reaching the endpoint of the map. However, he was at a residential area with no shop within sight. By chance, he saw a sign outside a usual looking detached house. It read "Macina Mecina", a shop that offers buffet meals. Out of his "hunger's curiosity", he entered and got ushered in by the proprietress (Ishino Yoko). Goro began to enjoy the real pleasure of a buffet feast, determined to go over and taste each and every dish...
