This is not so much a story as it is a slice of life. Or rather, it is a look into portions of the life of a girl named Alpha, together with the people around her. Alpha runs a little cafe on the outskirts of Yokohama. There are almost no customers, but Alpha does not mind at all since she has the occasional company of the old man, Oji-san, who runs the gasoline stand down the road, as well as that of his grandson Takahiro. This is a Yokohama of the future, when the sea covers most of the land and roads have disappeared under sand or water. Alpha is in fact an android, looking after the cafe during her owner's indefinite leave of absence.
