Project Status: ACTIVE This project has been updated within the past 3 months.

Jinrui wa Suitai Shimashita (人類は衰退しました, Humanity Has Declined), or "Jintai" for short, is a light novel series written by Romeo Tanaka and published by Shogakukan under their imprint, Gagaga Bunko. The first six volumes were illustrated by Touru Yamasaki and the latter three were illustrated by Sunaho Tobe. The series is complete at 10 volumes.

The series has spun off three manga adaptations and an anime television series which aired in summer of 2012.

Story Synopsis

For years, declining birth rates have forced what's left of the human race to cede more and more territory to other beings who have appeared to take advantage of the emptying ecological niche. Now, only a handful of humans remain among the remnants of civilization and Earth is dominated by faeries —tiny, ten-centimeter tall creatures of surprising intelligence. But humanity's importance isn't over quite yet, as young Watashi learns as she makes the decision to return to her hometown and assume her grandfather's position as an arbitrator between the races. Unfortunately, the job isn't going to be anywhere near as simple as she expected, and it's going to take a wisdom far beyond her years to achieve her most important mission.
