Shiawase Apartment's Okojo-san

A white ermine named Okojo-san lives in an exotic pet store run by a greedy manager, until one day he escapes. In the confusion that follows, he ends up unconscious in a garbage can, where college student Haruka Tsuchiya finds him. Mistaking him for a ferret, Tsuchiya takes Okojo home. At the Shiawase apartment complex, Okojo meets other pets, including a mouse named Chorori, along with the various eccentric human tenants. Together with his friends, Okojo struggles to adjust to life with humans, vacuum cleaners, and everything else that comes with human society.
