Midori no Yūgure

To live is to consume. It is the one immutable law that binds every creature, from the smallest microbe to the pinnacle of the food chain. Humanity, in its relentless pursuit of survival, has long sought solutions to its most pressing crises—food shortages and environmental decay. In the microscopic *Euglena*, scientists believed they had found that answer: a miraculous organism, barely 0.05 millimeters in size, heralded as the key to a sustainable future. It was a dream born of desperation, a biological panacea that promised to save a starving world. Yet, in a horrifying twist of nature, the dream has curdled into a waking nightmare. Without warning, the organism that was meant to be humanity's savior has turned predator. What began as a tool for renewal has become an indiscriminate devourer of human life, sparking a biological panic of unprecedented scale. The world watches in terror as its own salvation becomes the instrument of its potential extinction, forcing survivors to confront a terrifying question: will the architects of a new era be devoured by their own creation, succumbing to a foe so infinitesimal it defies comprehension?
