Jiang Xia operates as the Black Organization's most invaluable asset, employing a deceptively simple strategy: guiding Conan directly to his targets. When Kidd executes his elaborate thefts, Jiang Xia recovers the stolen treasures without hesitation—one of his carefully maintained identities conveniently works as the thief's trusted accomplice. The detective community unanimously acknowledges Jiang Xia's exceptional talent, citing only two flaws: his cases resolve with unsettling speed and his behavior remains perpetually unpredictable. Despite his proven prowess, Tokyo's detectives collectively refuse collaboration, whispering nervously that the darkness surrounding him cuts far too deep. Beneath his tranquil exterior lies a psychic who perceives spirits invisible to ordinary humans, collecting ghosts that haunt Tokyo's underbelly. Operating under multiple identities while concealing his true nature, Jiang Xia channels expertise from his previous life into navigating this investigation-heavy world. His cautious intellect and hidden abilities transform him from initial weakness into formidable strength—a operative the Black Organization depends on absolutely, yet one even experienced detectives instinctively avoid approaching.
