Humanity Has Declined (2012)

In a future where plunging birth rates have pushed humanity to the brink of extinction, a new dominant species known as "Fairies" has arisen. Now, the remnants of human civilization are but a whisper in a world echoing with the whimsical chatter of these intellectual beings. Amid this dwindling human population, a young and spunky heroine, known simply as 'Watashi', steps into her grandfather's shoes, inheriting the complex role of an intermediary between the races. As she navigates through the maze of inter-species diplomacy, Watashi finds herself entangled in a web of enigmatic fairy quirks and eccentricities, making her task far more challenging than she had ever anticipated. Despite the trials and tribulations, she remains undeterred, committed to maintaining a harmonious co-existence between the dwindling humans and the peculiar fairies. 'Humanity Has Declined' offers a poignant and whimsical look at the survival of the human spirit in a world where it is no longer the central force.
