Banished from the Viscount Guinas household with the scornful dismissal, "Just go and eat some of that grass over there," Aki—a reincarnated soul—finds himself cast out solely for possessing the supposedly worthless skill, [Plant Eater]. Yet far from a catastrophe, his expulsion is a welcome liberation. Freed from the gilded cage of noble obligations and petty familial politics, Aki embraces the chance to truly live his second life on his own terms, venturing into a world full of untold botanical wonders. It is there that his underestimated ability begins its true awakening. After consuming a leaf from the legendary World Tree and other mythical vegetation, Aki's skill transcends its mundane description. His stats skyrocket, new abilities manifest, and he rapidly transforms from a discarded servant into a legendary existence coveted by the entire realm. His path to glory solidifies when he rescues Saras, an elven girl, earning him the unprecedented trust of the elf tribe—a feat no other human has achieved. Suddenly, every noble, royal, and power broker desperate for an alliance with the elves finds themselves vying for Aki's favor. But he brushes them all aside, ascending to a position of influence that spans the continent itself. As for the Guinas family and his treacherous younger brothers who so casually cast him out? They find themselves ostracized, unable to secure even a thread of elven connection, and spiraling into a disastrous predicament of their own making—but that is merely the beginning of their woes...
