SSS-Rank Evolving Monster: From Pest to Cosmic Devourer

“Devouring Lifespan to grow stronger!!” When Ricky Stormwind—a washed-up office worker—drank himself to death, he expected eternal nothingness. Instead, he awoke in a new world… as a mosquito. Weak as an ant. Fragile as a piece of paper. Prey to everything. But this world is no ordinary one. Magic, monsters, and powerful beings dominate the land, with ruthless forces waging war for supremacy. And Ricky? He possesses a terrifying ability—he can drain lifespan from any living creature and use it to evolve. A single bite can grant him hours. A feast?..... Years!! Now, in a forest filled with predators and beside a village on the brink of destruction, Ricky must climb the evolutionary ladder—from insignificant pest to a calamity that could devour the world itself. But when his first real meal triggers a mass sacrifice, the world mistakes him for a rising Demon Lord. Bounties are placed on his head. Armies march to hunt him down. And lurking in the shadows, a forbidden power calls to him, promising a path beyond mere survival—one that could reshape reality itself. In a world where everything is prey to something greater, something horrendous… he will rise to become the apex.
