Gosho Aoyama’s Detective Conan manga, launched in 1994, has long stood as a global icon in the world of anime and manga. Over more than three decades, the adventures of the young detective have captivated fans with complex cases, thrilling storylines, and Conan’s unmatched deductive skills that always keep him one step ahead of criminals.
Beyond the mysteries Conan solves, another question has intrigued fans for years: who is the richest character in the entire Detective Conan universe?
This topic has sparked lively debates across social media, and the answer has finally been revealed: Karasuma Renya, the enigmatic billionaire behind the Black Organization.

Karasuma Renya is mentioned in the manga’s final chapters, but his true identity only comes to light as the story delves deeper into the Black Organization’s background. Though believed to have died decades ago, Karasuma’s influence and power continue to permeate every plan the organization executes.
Described as intelligent and cunning, he commands the Black Organization with absolute control, issuing orders through encrypted messages that showcase his supreme authority. Yusaku Kudo once remarked that if Karasuma were still alive, he would be the richest and most powerful man in Japan.
More than just the mastermind behind the Black Organization’s actions, Karasuma Renya possesses an immense fortune and wields global influence.
His wealth is estimated at around 100 billion yen (approximately 20 trillion VND). He has amassed over 300 priceless artworks and antiques, and owns the famed “Sunset Manor,” a golden mansion revered among tycoons as a symbol of unimaginable power and wealth.


One of the most fascinating details for fans is the mansion owned by Karasuma Renya. Known as Sunset Manor, or the “Sunset Mansion,” it is secluded on a mountain and described as having walls and structures that shimmer with gold.
The entire estate is like a treasure trove, with its golden exterior making it the ultimate symbol of Karasuma’s power. Especially on sunny days or at sunset, the sunlight reflects off the gold, creating a dazzling spectacle.
Karasuma Renya’s wealth and influence extend far beyond material possessions. His collection of over 300 priceless artworks and antiques cements his status as the most dominant figure in the Conan universe.
