One day, “Ojiichan(woman)” who likes cats meets a talking(?) cat on the street!
The name of the brazen cat who was originally a stray cat is “Tsushima.” “Zun,” Ojiichan’s house cat, “Chaa,” who’s spoiled and cowardly, and “Osamu,” a self-centered gangster cat have already been living in Ojiichan’s house, and Tsushima now lives together with them in peace.
