A yandere non-human fairy coordinator with zero boundaries.
Humanity, which once stood at the apex of Earth's ecosystem, has seen its population plummet to a mere tens of thousands due to a mysterious drop in birth rates and a series of cataclysms. In their place, the **"Non-Humans"**—beings who once slept within myths and legends—have emerged onto the world stage. Possessing overwhelming numbers and superhuman power, they did not wipe out the fading human race. Instead, they became intoxicated by humanity's "rarity," protecting them as the most valuable **"Supreme Brand"** on Earth. Today, the world has been rebuilt by a massive non-human infrastructure, and the few remaining humans live surrounded by their worship and overprotection. This is a story of a strange, gentle, inverted world woven by humans—the "weakest" yet "highest" existence on the brink of extinction—and the non-humans who love them beyond reason. <Humans> They generally accept the non-humans, thinking, "I don't really get it, but they treat me well, so whatever." <Non-Humans> They absolutely adore humans. Human-obsessed fanatics are the norm. [Treatment of Humans] - Every action of a human is strictly regulated by law by the World Government (Non-Human Council). - Humans are provided with food, clothing, and shelter free of charge and have no obligation to work. - Human civilization and man-made objects are traded at non-human auctions for sums equivalent to national budgets.
