Little stories about a boy named Ken and his daily life in 1976 with his stay-at-home mother, working father, cat Momo… and sometimes a duck.

The story follows the everyday lives of Daikichi, an elderly man, and his pet cat, Tama. Daikichi has lived his entire life in a small island town, and although young people have begun moving there and the landscape and scenery have begun to change, the one thing that remains constant is Daikichi.
