Plot

The series follows Yaniko, a catgirl who lives in a small apartment building in modern-day Japan and is addicted to smoking, regardless of the damage to her environment, her psyche, or her family. Almost all money she gets goes towards buying new cigarettes, and when she cannot buy new packs, Yaniko resorts to reusing spent cigarette butts or salvaging loose smokes off the street. As the series progresses, more catgirls are introduced with their own issues, along with their human landlord who tolerates their antics, and hints of an old civilization of cat-people capable of making their own tobacco products.
