My Magic Feeds on Death in Detective Conan

Yan Sagawa, a transcendent academic genius in the world of Conan, found his perfect scientific life…boring. He already possessed the [Strongest Xueba System], making him effortlessly brilliant. But then, a second golden finger arrived: the [Great Onmyoji System]. The catch? Magic was dying in this world, and this system craved souls from unnatural deaths to thrive. Now, with Conan, the living 'God of Death,' as his unwitting catalyst, Sagawa has found a new, thrilling purpose. He'll maintain his image as a national treasure genius, while secretly harvesting souls from every murder scene. They'll solve the case, but he'll claim the spoils. What twisted fate awaits a world where science hides a dark, hungry magic?
