Undercover in Detective Conan's World

A transmigrator from China has spent years embedded in Japan's underworld, operating under a Black Organization alias while secretly working to protect the world's natural order. Now defected but with his true identity still hidden, he navigates dual lives—by day, a brilliant stock market prodigy; by night, a guardian ensuring the innocent survive and heroes get their happy endings. In a world where gentle souls vanish too easily, he rewrites fate itself. No interference with canon romances, just one idealist's quest to save those the story forgot.
