Synopsis
A family of three rats, brothers Tata and Chichi, and their father, referred to only as "Dad", live in a tree trunk beside a river just outside Tokyo, just as their ancestors had for generations. However, sudden construction work by humans causes their home to be blocked off, forcing them to search for a new place to live upstream. Time becomes a factor as winter is fast approaching, leading the trio to venture in and around the dangerous city, encountering allies and enemies of all shapes and sizes.Characters
