F Grade Healer Becomes Strongest Biomancer

Birth of the Biomancer:Mio was the worst healer in Tokyo. F-grade, dead weight—her party kept her around out of pity until they did the math and left her bleeding in a ruined cathedral.Something ancient was waiting there. It offered her a Class that devours its hosts—a path of power that claimed the lives of the three Biomancers who came before her. Mio said yes anyway. She’d already felt the sting of a slow death; what was one more monster in her veins?Now pain is currency, death is fuel, and the hunger grows with every kill. The Bureau wants a weapon. Her sister wants her home for dinner. Mio agreed to both.In a world of Systems and Dungeons, power isn't a gift; it's a trade. And Mio is finally ready to pay the price.════════════════════What This Is:[1] This is a progression fantasy with system elements, but the system serves the story, not the other way around. Expect meaningful numbers, not stat spam.[2] Romance is not the focus. Mio has bigger problems. But expect a slow-burn later down the line![3] The story gets dark, but it's earned. No grimdark for shock value.
