A single teenage girl journeys through the crumbling ruins of civilization, a concrete jungle that has outlived mankind. However, just because she’s the last woman on earth doesn’t mean she’s alone. She’s accompanied by her dog Haru, an adorable and quick-witted shiba inu who will gladly lend his wisdom to his human companion. With such a pleasant conversation partner to keep the post-apocalyptic doldrums at bay, the end of the world might not be so bad after all!
