Demon Slayer's Double Life: Undercover at the Black Organization

What if you woke up in Detective Conan's world—as a corpse? Transmigrated into the body of a demon who burns in sunlight, our protagonist must navigate the deadly Black Organization while hiding his supernatural identity. Mistaken for dead by Conan himself, this white-haired infiltrator will turn the criminal underworld upside down. No cannibalism, no typical system—just high-stakes deception, original murder cases, and a slow-burn romance with Gin. Can he save the police academy group and seize power from within before his secret is exposed?
